Capture by voice or text in seconds. Thoth turns everyday thoughts into a private, on-device personal memory you can search, connect, and act on with Google Tasks, Calendar, and smart reminders.
Designed for the moments when opening a traditional notes or todo app creates too much friction.
Save facts, preferences, ideas, and notes by speaking or typing. Ask Thoth about anything you've saved in plain language—Thoth selectively retrieves only the relevant local memory snippets needed to answer your question, keeping your personal context private and organized.
Manage tasks, subtasks, lists, and recurring due dates with two-way Google Tasks sync. Check or schedule Google Calendar events, look up contacts, and compose confirmation-gated Gmail drafts.
Capture thoughts in seconds from the Home Screen Widget, Quick Settings Tile, persistent notification, or your Wear OS smartwatch tile and complication.
Organize notes with color tags, pinning, archiving, smart memory curation, location map view, and an interactive Knowledge Graph showing how your memories link together.
Your memories, notes, and conversations live in a local SQLite database on your phone with Android cloud auto-backup disabled. We never sell personal data.
Speak or type a thought from the app, home-screen widget, Quick Settings tile, or Wear OS watch.
Thoth stores your context locally in SQLite, links related facts, and keeps your notebook and tasks tidy.
Sync with Google Tasks, schedule Calendar events, set exact-time or location reminders, and get daily briefings.
No vague privacy claims. Here is the exact boundary between your local SQLite vault, AI requests, and Google permissions.
Your personal memories, Keep-style notes, reminders, Knowledge Graph, Memory Map, and offline speech-to-text stay in a local SQLite database on your phone with Android cloud auto-backup disabled (allowBackup="false").
When you actively send a chat message, a local RetrievalGate selects only the relevant memory snippets needed for your prompt—never dumping your entire database—and sends them over TLS.
Sign-in uses basic profile identity only (id_token). Separate scopes for Google Tasks, Calendar, Contacts, and confirmation-gated Gmail drafts are requested incrementally only when you connect or use them.
Open Settings → Data Boundary & Local Vault anytime to switch Tasks back to local-only, disconnect Google Workspace scopes, or wipe your local SQLite database in one tap without deleting your account.
No API keys required from you. Transparent plan limits.
Everything you need to capture local memories, notes, reminders, and tasks.
Built for daily power users who rely on Thoth as their personal assistant and memory hub.
Your memories, notebook entries, tasks, and conversation history are stored locally in an SQLite database on your Android phone. Android cloud auto-backup is disabled for personal memory data. When you ask the AI assistant a question, Thoth only includes the relevant context needed to answer your request.
No. Thoth uses a secure, managed server-side AI connection through Firebase Functions so you can start immediately after signing in with Google.
You have full control at all times. You can wipe your local database and delete your cloud account in one tap directly inside the app (Settings → Delete Account) or on the web at hermes-thoth.web.app/delete-account.
