Saarthee CoPlanner by NAS

Your personal operating system for mail, calendar, and work

One place that reflects mail, calendar, tasks, files, and Notion — with sync you can trust and AI that grounds on your data, not a blank chat window.

Pilot is invite-only — connect Google or Microsoft mail when you're in.

What Saarthee does today

Core read + send paths are live for Gmail and Microsoft. Calendar CRUD and deeper automation are on the roadmap.

  • Unified inbox
    Gmail and Outlook in one list — synced to your database, filterable by account, with read detail and send on the providers you connect.
  • Today hub
    Mail summary, calendar, and tasks on one screen. Built for people who live across Google and Microsoft, not just one vendor.
  • Your truth layer
    OAuth into your accounts; metadata lands in your Postgres. Search and AI read durable cached data — not only live API calls per click.
  • AI coworker, rules first
    Sync and deterministic workflows come first. AI assists on cached mail and calendar; destructive actions stay gated with human confirm.

Why Saarthee is different

Planners rarely own email deeply. Mail clients don't build a cross-stack object model. AI assistants often skip durable sync. Saarthee bridges that gap.

  • Not another chat wrapper

    A personal operating system — inbox, calendar, files, and Notion in one place — not a session that forgets your mail when the tab closes.

  • Engineering-grade sync

    Incremental sync, outbox for sends, idempotency, and Sync Health visibility. Built for reliability as accounts and volume grow.

  • Trust by design

    Revoke connections in Settings, explicit scopes, privacy and terms in-app. You control which providers are linked and when.

  • Multi-vendor by default

    Connect several Google and Microsoft mailboxes. Saarthee normalizes them into one queryable store — the gap planners and mail clients leave open.
