GemiHub
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. Read PDFs, EPUBs, and notes with quote-anchored memos, connect external tools, search across your documents by meaning, and automate repetitive tasks — all while keeping your data in your own Google Drive.
Read & Memo
Open PDFs, EPUBs, Markdown, and images, select a passage, and attach a memo right where you read. Quotes are highlighted and jump both ways. Notes are saved as plain Markdown in your Drive.
Personal Dashboards
Build a home screen from file viewers (Markdown, PDF, EPUB, images), memo lists, cards, editable tables, kanban boards, workflow output, and web embeds.
AI Chat
Have a conversation with AI that can read your files, search the web, generate images, and use external tools — all on its own.
Ask Your Files
Search your Drive files by meaning, not just keywords. Search for "meeting" and get results mentioning "conference" too.
Notes & Editor
Jot down notes in Markdown. Save ideas and meeting notes straight to Drive.
Workflows
Just describe what you want and AI builds an automation workflow. Works with Drive, the web, and external services.
Obsidian-Friendly
Use Obsidian-compatible Canvas files and sync notes with the GemiHub Drive Sync plugin through the same Drive metadata.
Plugins
Add new features from GitHub. Plugins can use AI and Drive, so you can build custom tools and advanced automation.
One-Click Publishing
Turn Drive files into public pages, or use Pro features for CDN-hosted HTML pages, custom domains, and AI-assisted web building.
Works Offline
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.
Encrypted Secrets
Store API tokens, passwords, and other secrets as RSA + AES encrypted files in your Drive, organized into folders and searchable by name or description — without ever exposing the value.
Your Data, Your Control
No external database. Everything stored in your Google Drive. Supports encryption and self-hosting.
See It in Action
Read, Highlight & Memo
Read PDFs and EPUBs in the built-in viewers, select a passage, and add a memo. Quote-anchored highlights link both ways between the document and its memo timeline.
Personal Dashboard
Create a home screen with file viewers (Markdown, PDF, EPUB, images) with per-document memos, memo lists, cards, tables, kanban boards, workflow output, and web embeds. Dashboards are saved as plain .dashboard files in Drive.
Dashboard Editing
Toggle edit mode to add widgets, drag and resize panels, configure sources, undo or redo layout changes, and switch between rendered and raw YAML views.
Workflow Widgets
Run a workflow from a dashboard and render the result as cards, a table, Markdown, or HTML. Optional auto-refresh keeps generated reports current.
Kanban Boards
Turn Markdown files in a folder into a kanban board. Create cards from the board header or drag cards between columns to update frontmatter in Drive.
Secret Manager
Create, browse, unlock, copy, and update RSA + AES encrypted values from a dashboard widget. Organize secrets into folders and search by name, description, or visible metadata without ever exposing the encrypted value.
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.
External Skills
Install Agent Skills from the official catalog with one click — like OKF Authoring, which teaches the AI to turn your notes into knowledge bundles.
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.
OKF Knowledge Bundles
Keep curated Markdown knowledge bundles (OKF) in Drive and switch them on per chat — the AI answers with your domain knowledge always in context.
Obsidian-Compatible Canvas
Open .canvas files with text cards, groups, file previews, web pages, and curved links. Edit mode lets you arrange cards and connections.
One-Click Publishing
Turn any Drive file into a public web page. Share via URL with no hosting required.
Push/Pull Sync
All data lives in your Google Drive. Push and pull changes with automatic conflict handling and diff previews.
Premium Plans
GemiHub is useful on the free plan by default. Paid plans are for features that need heavier server-side processing, such as streaming files over 20 MB, Gmail integration, or temporary upload/edit URLs. Choose Pro when you want to add AI-assisted web service publishing with natural-language build and edit flows, custom domains, and login support.
