AI That Acts, Not Just Answers
GemiHub is an AI assistant that reads your files, finds what you need, and gets things done on its own. Connect external tools, search across your documents by meaning, and automate repetitive tasks — all while keeping your data in your own Google Drive.
Ask a question and the AI figures out what to do: read a file, search your Drive, look things up on the web, or call an external service. You just ask — it handles the rest.
Your files are indexed so the AI can find relevant information even when the exact words don't match. Ask "when was the budget meeting?" and it finds your "Q3 finance review" notes.
Hook up web search, databases, or any compatible service. The AI automatically discovers what's available and uses it during your conversation.
String together AI prompts, file edits, web requests, and more into automated workflows. Or just tell the AI what you want and it builds the workflow for you.
Have a conversation with AI that can read your files, search the web, generate images, and use external tools — all on its own.
Search your Drive files by meaning, not just keywords. Search for "meeting" and get results mentioning "conference" too.
Jot down notes in Markdown. Save ideas and meeting notes straight to Drive.
Just describe what you want and AI builds an automation workflow. Works with Drive, the web, and external services.
Add new features from GitHub. Plugins can use AI and Drive, so you can build custom tools and advanced automation.
Turn any Drive file into a public web page. Share via URL with no hosting required.
All files cached in your browser for instant access — even without internet. Edit offline, then push changes to Drive with one click. Conflicts are detected automatically.
No external database. Everything stored in your Google Drive. Supports encryption and self-hosting.

AI Chat & File Management
Write notes in a rich editor and let AI proofread or summarize them. Chat with web search, file search by meaning, image generation, and connections to external tools.

MCP Apps
Connect external apps via MCP (Model Context Protocol). The AI discovers available tools automatically and uses them in your conversation — calendars, databases, and more.

Workflow Builder
Build automation with a drag-and-drop editor. Connect AI prompts, Drive operations, and web requests into a single flow.

AI Workflow Generation
Describe what you want in plain language and AI creates the workflow for you, with a live preview.

Smart File Search
Sync your Drive files to meaning-based search. Ask questions naturally and get answers drawn from your own documents.

Push/Pull Sync
All data lives in your Google Drive. Push and pull changes with automatic conflict handling.

One-Click Publishing
Turn any Drive file into a public web page. Share via URL with no hosting required.

Fast & Low Cost
Input: ~20–40M tokens. Output: ~3M tokens. For personal development and data analysis, this is practically unlimited — even processing hundreds of books barely scratches the surface.
High Intelligence & Complex Reasoning
Input: ~4–5M tokens. Output: ~800K–1M tokens. More expensive than Flash, but still enough for thousands of standard chat round-trips.
Index & Search Your Documents
Indexing is extremely cheap — $10 covers tens of millions of tokens (thousands of PDF pages). Retrieval uses standard model pricing; with Flash, the cost is negligible.
With Gemini 3 Flash as your File Search engine, $10/month goes surprisingly far. Build a personal AI librarian from your entire PDF library without worrying about the budget.

GemiHub uses your Google account to sign in. Here's what we access and why:
Your Google account is used only for authentication. Your name and email are not stored or displayed.
Chat history, workflows, and settings are stored in a dedicated "gemihub" folder on your Drive. Files outside the app are never accessed.
Your data is never sold or shared. Everything stays in your own Google Drive.
No database — all data lives in your Drive. If this service shuts down, just run your own instance and everything is right where you left it.
