Zinthi Mail

A shared inbox for small teams — read, reply, and discuss in the same place.

Internal Comments Assignments Status Tracking Gmail OAuth Now in early access
  • 01 Discuss any thread alongside the email itself, with mentions and reactions — never sent to the customer.
  • 02 Hand a thread to a teammate with one keystroke. Track open, waiting, or done — like Linear, but for your inbox.
  • 03 Connect via OAuth — your address stays yours, your mail stays in Gmail. We never store mail bodies.
  • 04 Use Mail standalone, or alongside Chat and Boards in the full Zinthi workspace — same inbox, two places.

Legal cleared 1.5% flat. The 99.9% SLA is the one to push back on.

Zinthi Chat

One workspace for messages, files, calls, and the things in between.

Channels & DMs Voice & Video Threaded conversation File sharing Coming soon
  • 01 Channels and DMs that feel like Slack — but without the bloat. Threads, mentions, reactions done thoughtfully.
  • 02 Drop into a voice or video call from any channel with one click, no link sharing, no third-party tools.
  • 03 When a thread becomes work, convert it into Mail or an Epic — context follows wherever the conversation needs to go.
  • 04 Native desktop via Tauri. Lightweight, fast, distraction-free — built for the way teams actually work.

Love the new flow on step 3. The drop-in call idea is really clicking.

Zinthi Boards

An infinite canvas for thinking together — sticky notes, diagrams, live cursors.

Collaborative Canvas Live Cursors CRDT Sync Drop-in calls Coming soon
  • 01 An infinite canvas with sticky notes, frames, arrows, and shapes — built for the messy middle of figuring something out.
  • 02 See your teammates' cursors in real time, sub-second sync. CRDT-backed conflict resolution means nothing ever overwrites.
  • 03 A board opens the moment a call starts. No exports, no screenshots, no "let me share my screen."
  • 04 When a board needs to become a doc, an issue, or an email — convert it directly, the rest of Zinthi is right there.

Problem
Teams lose context when switching tools.
Next step
Prototype the channel → board flow.
Insight
Drop-in calls feel more natural than scheduled meetings.
Opportunity
Unified workspace = less overhead.
