Features

AI-native capabilities unique to PlainHub.

AI-Native Online Editor

PlainHub has AI integrated into the editor. With MCP/CLI integration, it can also be controlled from Claude Code and Cursor.

"Make this paragraph more concise" → AI suggests edits → review diff → apply with one click

GitHub Issues Integration

While editing documents, you can view, create, comment on, and close Issues — all from the AI panel. No need to open the GitHub Issues page.

"Show me the Issues for this repo" "Create a bug report Issue" "What's in Issue #1?" "Comment 'fixed' on Issue #1" "Close Issue #1"

Idea Development — Brainstorm with AI while writing

Don't just jot down ideas — develop them through conversation with AI. In PlainHub, your notes and AI live on the same screen.

1. Write down your idea (e.g., new service concept, article outline, business plan) 2. Consult AI "What are the weaknesses of this idea?" "Suggest 3 differentiators from competitors" "Make this proposal more specific" 3. Incorporate AI's suggestions and update your notes on the spot 4. Save → idea evolution is automatically recorded in Git history

How it differs from other tools:

  • ChatGPT/Claude conversations → conversations flow away. You need to copy results somewhere else
  • PlainHub → the document itself is your workspace with AI. Edits are saved in place

Access your ideas from any device. Jot something down on your phone, brainstorm with AI, and record it all in Git.

Edit & Deploy from Anywhere — Just save to go live

Saving in PlainHub = committing to GitHub. If you use a GitHub-connected hosting service like Vercel, Netlify, or Cloudflare Pages, saving triggers automatic deployment.

Open PlainHub on the go → Fix a document, update content, change a config value → Optionally ask AI: "make this text more concise" → Save (Ctrl+S) → Commit to GitHub → auto-deploy → live on production No PC, IDE, or terminal needed. Just a browser.

PlainHub itself is deployed using this mechanism (Cloudflare Pages).

Find documents with natural language

Cross-repository search + AI enables natural language queries.

"Which is the latest version of the doc about ~?" "Where was that security policy again?" "Summarize the action items from last month's meeting notes"

AI-powered file organization

Let AI organize your scattered documents.

"Organize these scattered documents into a logical directory hierarchy" → AI analyzes file structure → suggests hierarchy → auto-rename and move after approval

File server-like document upload

Upload documents (PDF, Word, Excel, etc.) directly to your GitHub repository via drag & drop or file picker. Use GitHub like a file server.

Drag & drop from desktop → auto-commit to GitHub repo → version-controlled file server

Learn with your editor — AI Learning Mode

Have AI read your notes and quiz you in an interactive format. Not just writing — a tool to reinforce what you've written.

1. Open your notes (e.g., vocabulary list, exam prep summary) 2. AI asks questions based on your content (active recall) "What does 'ethical' mean?" "List 3 items included in important matter explanations" "Answer: journalize accounts receivable" 3. Answer → AI gives feedback → records comprehension 4. Study records are saved in Git → review your progress

The place where you write and the place where you learn are the same. GitHub becomes the backend for your study records.
