Two products,
one conversation store.

The free desktop is a complete product. Pro is the convenience layer for multi-device users.

  • Native macOS via Tauri + React + Rust

Why pay,
when the desktop is free.

Pro doesn't unlock features. Pro pays for infrastructure you cannot replicate alone.

01

Cross-device access

Your chats on iPad, iPhone, web, or another Mac. Requires a server. The desktop app stays free; the cloud is what costs us money.

02

Append-only sync

An append-only conversation log replicated across every device you sign in on. No copy-paste, no exports, no diff.

03

Backup

Your Mac dies, your chats survive. Your laptop goes through airport security, your chats survive.

04

Search across everything

Query your entire history from any device. No more "where was that thread about…".

/ 03

Zero-knowledge,
by architecture — not by policy.

ChatGPT.com, Claude.ai, every chat SaaS has admin access to user content. We can't, by design.

Your passphrase derives a key in your browser using Argon2id. Conversations are encrypted with AES-256-GCM on the device, then uploaded as opaque blobs. The server stores blobs and never sees plaintext content.

A database breach, a subpoena, an internal mistake — none of them can leak what was in a chat. That's the moat. It's the thing nobody else can copy without rewriting from scratch.

Honest phasing.
No promises before they ship.

We won't claim active web chat before the relay lands. Here's exactly where we are.

shipping next

Phase 3 · sync MVP

after Phase 3 lands

Phase 4 · active web chat

WebSocket relay. Your Mac is the engine; the browser is a remote control. Chat from your iPad, your Mac at home does the talking.

Phase 5 · team & mobile

Team workspaces, mobile PWA, plugin marketplace. Only after the solo product is loved.
