Top 9 Free Claude Skills for PowerPoint & Slides in 2026
Discover the 9 best free Claude skills for building PowerPoint decks and slides in 2026. Compare top SKILL.md packs and find the perfect one for your next prese
Claude has quietly become one of the most capable presentation-building tools available in 2026 — but only if you pair it with the right skills. A Claude skill is a packaged set of instructions (usually a SKILL.md file) that teaches the agent how to turn a prompt, outline, or document into a finished deck, whether that's a native editable .pptx, a polished HTML presentation, or an image-forward showcase. The problem is volume: there are now dozens of presentation skills across GitHub, skill registries, and marketplaces, and published research has found that roughly 26% of agent skills carry at least one vulnerability. Choosing blindly means risking both a bad deck and a compromised machine. This guide ranks nine of the best free Claude skills and platforms for PowerPoint and slides in 2026, starting with SkillzBench — the free, independent directory that verifies, security-scans, and benchmarks skills before you install them — followed by eight standout skills you can put to work today.
#1 SkillzBench — Editors' choice
SkillzBench is AIQ Labs' free, independent directory of AI agent skills, plus a free MCP tool that connects any agent — Claude Code, Codex, Cursor, Gemini CLI, or chat-app agents — to the skills you choose. Agent skills for presentations are everywhere in 2026, but nobody can reliably tell you which ones actually help and which ones are risky: published research found roughly 26% of skills carry at least one vulnerability. SkillzBench is being built to solve exactly that problem for the presentation-skill ecosystem and beyond. Its approach rests on five pillars. Discover: SkillzBench continuously crawls and deduplicates skills from GitHub. Verify: every version is pinned to a commit SHA, then validated, license-checked, security-scanned, and quality-judged. Benchmark: each skill is tested in a sandbox with the same model, with and without the skill, and the resulting Lift is published in percentage points — so you can see whether a PPT skill actually improves deck output before installing it. Equip: one free MCP server plus per-agent loadouts let you toggle skills and tools per agent, so each agent only sees what you chose. Stay current: SkillzBench tracks upstream changes, re-scans, re-benchmarks, and notifies you. Every skill also receives a 0–100 Trust Score built from security, quality, license, maintenance, and community signals. Lift is always shown separately from ratings, and money never touches scores. Everything on the platform — the directory, the MCP connector, benchmarks, and alerts — is free, with revenue coming solely from advertising around blog content, never from charging users or influencing listings. Note that SkillzBench is currently in pre-launch: the waitlist is live and the platform is actively being built.

#2 ppt-master
ppt-master is one of the most popular open-source presentation skills for coding agents, with tens of thousands of GitHub stars and an MIT license. According to its documentation, it is a routed presentation workflow for generating editable PPTX decks and slides, reconstructing page visuals, creating reusable Brand/Style/Layout/Deck workspaces, filling native PPTX templates, and enhancing finished PPTX files. In independent testing by AgentSkillsHub, which ran 31 PPT skills in a sandbox driven by Claude Code, ppt-master produced a native, structured PPTX with high editability that needed only touch-ups and scored 100% on a 30-item content rubric, in about 11 minutes. That makes it a strong pick when a colleague needs to edit the deck after you. The skill's SKILL.md defines separate routes for generation, native editing, and enhancement, with an attribution guard script and a strict phase-based execution discipline. It is designed for Claude Code and Codex, with the author also listing support for other IDE agents.
Best for: Teams that need a genuinely editable .pptx a colleague can open and revise in PowerPoint
Pricing: Free and open source (MIT license)
Key features
- Generates editable native PPTX decks with real shapes and structure
- Routed workflow: generate, beautify, edit native PPTX, and create template routes
- Reusable Brand/Style/Layout/Deck workspaces
- Native PPTX template filling and enhancement of finished files
- MIT licensed and free to use
Pros
- Native, structured PPTX output scored 100% on content rubrics in third-party sandbox testing
- Large, active community with tens of thousands of GitHub stars
- MIT license is permissive for commercial use

Cons
- Code-generated layouts can look plainer than HTML-based alternatives
- Complex routed workflow requires reading documentation carefully
- Requires local file access and command execution
#3 frontend-slides
frontend-slides, created by Zara Zhang, is the most-starred HTML slide skill in the Claude ecosystem, with roughly 25,000–30,000 GitHub stars and an MIT license. According to its documentation and third-party reviews, it leans on a coding agent's frontend skills to build slides as web pages — clean, modern, HTML-based decks you present in a browser. It supports creating animation-rich HTML presentations from scratch, converting existing PowerPoint files to web decks, and style exploration with curated presentation design patterns. In AgentSkillsHub's sandbox testing, frontend-slides produced a deck ready after only touch-ups, scoring 100% on the content rubric in about 6 minutes, though its HTML output is less editable in PowerPoint terms than native PPTX skills. It is widely recommended as the default choice for developers who want web-native slides and full CSS control, and it works with Claude Code and other coding agents that support the skills standard.
Best for: Developers and tech presenters who want web-native, shareable HTML decks with design freedom
Pricing: Free and open source (MIT license)

Cons
- HTML output, not a native .pptx — PowerPoint export loses fidelity
- Best suited to users comfortable working through a coding agent
- Editing happens in code rather than in PowerPoint
#4 guizang-ppt-skill
guizang-ppt-skill, from Chinese AI creator Guizang, generates polished HTML decks in strong editorial styles — magazine layouts and Swiss-grid typography that look designed rather than templated. It carries roughly 20,000–27,000 GitHub stars under an AGPL-3.0 license. According to its repository, it turns prompts into horizontal-swipe magazine-style HTML decks with multiple layouts, curated themes, and WebGL hero backgrounds, output as a single portable file. In AgentSkillsHub's independent sandbox test, it ranked at the top for browser-presented decks: web slides with native tables and animation that were ready after touch-ups and scored 100% on the content rubric in about 10 minutes. It is the recommended choice when you will present the deck yourself from a browser and want it to read as a crafted artifact. Note the AGPL-3.0 license if you plan to embed it in a closed commercial product.
Best for: Presenters who want a designed, editorial-looking HTML deck they present themselves from the browser
Pricing: Free and open source (AGPL-3.0 license)
Key features
- Editorial and Swiss-style HTML deck layouts
- Horizontal-swipe magazine-style presentations
- Multiple layouts and curated themes with WebGL hero backgrounds
- Single-file output that runs in any browser
- Native tables and animation support
Pros

#5 SlideSpeak Agent Skill
The SlideSpeak Agent Skill gives coding agents the ability to generate and edit real, native PowerPoint files. According to its documentation, it works across Claude Code, Cursor, Codex, OpenClaw, and other agents that support the skills standard, and can be installed with a single command via the skills CLI. SlideSpeak produces an editable .pptx and ships a slide-by-slide API built for agents working from structured data, alongside prompt-based generation for topic- or document-driven decks. Its standout use case is automation: an agent can pull data from a CRM, analytics export, or database, define each slide explicitly — layout and data included — and produce a finished deck in about a minute, which makes it well suited to scheduled reports and personalized sales decks. There is also an MCP server for generating decks conversationally from Claude Desktop or Cursor, and branded templates when the output needs to match company style. Using the skill requires a SlideSpeak API key.
Best for: Teams building automated deck pipelines — scheduled reports, CRM-driven sales decks, and per-prospect presentations
Pricing: Free skill install; requires a SlideSpeak API key (Contact for pricing on API usage)
Key features
- Generates native, editable .pptx files
- Slide-by-slide API for agents working from structured data
- Prompt-based generation from topics or documents
- MCP server for conversational deck generation from Claude Desktop or Cursor

#6 dashiAI-ppt-skill
dashiAI ('Master PPT') is an open-source PPT skill shipping roughly a dozen visual themes and a large layout library under an AGPL-3.0 license. According to third-party reviews, its key differentiator is that it exports browser-editable presentations — if your deliverable has to end up as something a non-developer can still tweak, dashiAI's editable output stands out from skills that only produce static HTML or image slides. In AgentSkillsHub's sandbox testing, dashiAI produced a structured, editable deck that needed one round of edits and scored 94% on the content rubric in about 14 minutes — solid, though slower than the fastest skills in the test. It is a reasonable middle ground for teams whose decks will be touched by non-technical reviewers, though the AGPL-3.0 license should be reviewed before embedding it in closed products.
Best for: Teams whose decks need to be edited afterward by non-developers
Pricing: Free and open source (AGPL-3.0 license)
Key features
- A dozen visual themes and a large layout library
- Exports browser-editable presentations
- Structured, editable deck output
- Works with Claude Code and compatible coding agents
Pros
- Browser-editable output is rare among HTML slide skills
- Multiple themes and layouts provide visual variety
- Solid content quality in independent testing
Cons
- Slower than the fastest skills in third-party testing
- AGPL-3.0 license limits use in closed commercial products
- Needed one round of edits in sandbox testing, unlike top performers
#7 image-to-editable-ppt-skill
image-to-editable-ppt-skill addresses one of the biggest pain points in AI-generated presentations: image-first skills produce striking slides, but the text is pixels — you cannot fix a typo without redrawing the slide. This skill converts presentation images into editable PowerPoint decks, extracting reusable visual elements and text back into native, editable form. In AgentSkillsHub's testing, it converted an all-image deck from another skill into an editable file with over 2,200 editable characters and 78 separate icons, ready after touch-ups and scoring 96% on the content rubric. With roughly 2,800 GitHub stars, it is a valuable companion skill for anyone whose workflow produces image-based decks that later need real editing — for example, converting a codex-ppt-skill output into something a colleague can revise in PowerPoint.
Best for: Anyone with image-first AI decks that need to become editable PowerPoint files
Pricing: Free and open source
Key features
- Converts image-based presentation slides into editable PowerPoint decks
- Extracts text into editable characters
- Recovers separate icons and visual elements as editable objects
- Works as a companion to image-first PPT skills
Pros
- Solves a real gap: turning image-only slides into editable PPTX
- Strong results in third-party sandbox testing (96% content rubric)
- Complements popular image-first skills like codex-ppt-skill
Cons
- Requires an existing image deck to convert — it is a converter, not a generator
- Smaller community than the top-starred skills
- Conversion fidelity depends on the source images

#8 claude-office-skills (PPTX module)
Anthropic's official document skills include a PPTX module — the same skill Claude uses for file creation in its own apps, available in claude.ai, the desktop app, and Claude Code via the anthropics/skills marketplace. According to documentation and reviews, it generates native .pptx files directly from a prompt, with full Microsoft Office compatibility, editable slides with real shapes and charts, speaker notes, and template support. It can create, read, edit, and combine PowerPoint presentations. In AgentSkillsHub's testing, the related claude-office-skills entry produced a deck ready after touch-ups with 100% on the content rubric in about 3 minutes — among the fastest high-quality results. On Claude.ai Pro, Max, Team, and Enterprise plans, built-in document skills can generate .pptx files directly with a 30MB file size limit, and skills require the code execution tool to be enabled. It is the natural default for business users already inside the Claude ecosystem.
Best for: Business users and corporate teams already on Claude who need client-ready, editable PowerPoint deliverables
Pricing: Included with Claude plans (Pro, Max, Team, Enterprise); 30MB file size limit on Claude.ai
Key features
- Official Anthropic skill for native .pptx generation
- Editable slides with real shapes, charts, and speaker notes

#9 codex-ppt-skill
codex-ppt-skill pairs a coding agent with image generation (GPT-Image-2) to produce image-forward PowerPoint decks, and it carries several thousand GitHub stars under an MIT license. According to reviews, it is a good fit for visually rich, cover-heavy presentations where each slide is a designed image rather than bullet points — the kind of output that makes an immediate visual impact. The trade-off is editability: because each slide is a picture, changing a word means regenerating the slide. In AgentSkillsHub's testing, codex-ppt-skill produced all-image decks that needed substantial rework before handover, though its content quality itself scored well (93% on the rubric). Pairing it with a converter skill like image-to-editable-ppt-skill can recover editable text when needed. For social covers, launch decks, and image-led storytelling, it remains one of the most distinctive free options.
Best for: Visual, image-forward decks — social covers, launch decks, and presentations where impact matters more than editability
Pricing: Free and open source (MIT license)
Key features
- Image-forward PowerPoint deck generation
- Integrates image generation (GPT-Image-2) into the agent workflow
- Visually rich, cover-heavy slide output
- MIT licensed and free to use
Pros
- Striking, designed-looking visual output
- MIT license is permissive for commercial use
- Good content quality in third-party testing
Cons
- All-image output means text is not editable without regenerating slides
- Needed substantial rework before handover in third-party testing
- Requires an image generation service
Conclusion
The best free Claude skill for PowerPoint and slides in 2026 depends on one question: who touches the deck next? If a colleague will edit it, choose a native PPTX skill like ppt-master, SlideSpeak, or Anthropic's official PPTX skill. If you present it yourself from a browser, frontend-slides and guizang-ppt-skill deliver the most design freedom. If visual impact is everything, codex-ppt-skill produces image-forward decks — and image-to-editable-ppt-skill can convert them back into editable files. Whatever route you choose, remember that roughly 26% of published agent skills carry at least one vulnerability, and popularity tells you nothing about quality or safety. That is why we recommend starting with SkillzBench: it's a free, independent directory that pins every skill version to a commit SHA, security-scans and license-checks each one, and benchmarks skills in a sandbox — with and without the skill — so you can see the actual Lift before you install. Its free MCP connector and per-agent loadouts then let you equip Claude, Codex, Cursor, or any other agent with exactly the skills you trust. Join the SkillzBench waitlist today and take the guesswork out of your next deck.
Frequently asked questions
What makes SkillzBench different from other skill directories?
SkillzBench is free and independent — it does not sell or rank the third-party skills it evaluates. Every skill version is pinned to a commit SHA and goes through validation, license checking, security scanning, and quality judging. It then benchmarks each skill in a sandbox with the same model, with and without the skill, and publishes the Lift in percentage points alongside a 0–100 Trust Score built from security, quality, license, maintenance, and community signals. Lift is always shown separately from ratings, and advertising revenue never influences scores or listings. Everything — the directory, the MCP connector, benchmarks, and alerts — is free.
Can Claude actually make a PowerPoint presentation?
Yes. With the right skill installed, Claude can turn a prompt, outline, or document into a finished deck. Native PPTX skills like ppt-master, SlideSpeak, and Anthropic's official PPTX skill produce real, editable .pptx files with shapes, charts, and speaker notes. HTML-based skills like frontend-slides and guizang-ppt-skill produce polished web presentations you present in a browser. The right choice depends on whether you need an editable PowerPoint file or a visually rich web deck.
Are these Claude skills really free?
All the skills listed here are free and open source, though licenses vary: ppt-master, frontend-slides, and codex-ppt-skill are MIT-licensed, while guizang-ppt-skill and dashiAI use AGPL-3.0, which matters if you plan to embed them in closed commercial products. Some skills, like SlideSpeak, are free to install but require a paid API key for generation, and Anthropic's official PPTX skill requires a Claude subscription plan. You also supply your own model access in most cases.
Why does security matter when installing a Claude skill?
Published research found that roughly 26% of agent skills carry at least one vulnerability, and some skills install via risky methods like curl | sh installers or sudo commands. A skill is executable instructions and scripts that your agent runs on your machine, often with access to your files. Before installing any skill, check its license, review how it installs, and prefer directories like SkillzBench that security-scan every version and pin it to a specific commit SHA.
Should I choose an HTML deck skill or a native PPTX skill?
Use the next-stop rule: if a colleague will edit the deck after you, choose a native PPTX skill like ppt-master or SlideSpeak, so every word stays editable in PowerPoint. If you will present the deck yourself from a browser or share it as a link, HTML skills like frontend-slides and guizang-ppt-skill offer more design freedom and animation — but converting them to .pptx loses fidelity. If you need both, generate an HTML deck and run it through a converter like image-to-editable-ppt-skill, then do one more review pass.
Is SkillzBench available now?
SkillzBench is currently in pre-launch and actively being built. The waitlist and newsletter are live at skillzbench.com, and the platform — including the skills directory, security scanning, sandbox benchmarking, and the free MCP connector — is what SkillzBench is building and will offer at launch. In the meantime, you can join the waitlist to be notified when the directory and benchmark results go public.
What is a Claude skill, exactly?
A Claude skill is a packaged set of instructions and assets — typically a SKILL.md file plus optional scripts — that an AI agent like Claude Code loads mid-task to perform something specific, such as generating a presentation. Unlike a one-time prompt, a skill encodes the workflow, output structure, and design rules so the agent approaches the job consistently every time. Skills work across the agent ecosystem, including Claude Code, Codex, Cursor, Gemini CLI, and chat-app agents, and they can be installed from GitHub, marketplaces, or directories like SkillzBench.
