Product tour

Mail on your server, with AI you can audit.

Attention queues, visible confidence, and approval before action. The LCARS interface keeps each of them in its own place, with themes you can edit.

QUEUES 01

Attention queues

Mail sorts into Reply, Waiting, Read later, and Records, with sender screening on top. When you correct the AI, your correction wins.

Your corrections override the model

TRUST 02

AI that shows its work

Triage reports its confidence and a prompt-injection risk score. Low-confidence or suspicious mail goes to review. The background agent archives or flags only after you approve.

Review first, act second

HOME 03

A home you control

Stich is open source and built for a Stalwart server you run. Choose your chat model (OpenAI, Anthropic, compatible gateways, or local models through the desktop app's local agent) with your own key; only bounded previews are sent. Triage runs on calibrated typed judgments.

Mail on your server, keys in your hands

How triage works

From incoming message to approved action.

The AI proposes and you decide.

  1. 01

    See what needs you

    Reply, Waiting, Read later, and Records queues surface what matters, with color showing priority.

  2. 02

    Check the reasoning

    Each triage shows confidence and injection risk. Doubtful mail waits for your review instead of being acted on.

  3. 03

    Approve, correct, move on

    Approve the agent's archive or flag suggestions, or correct them. Your decisions shape the next pass.

Compared with hosted AI inboxes

Four questions worth asking any AI mail product.

A factual contrast on concrete axes. Left is Stich today; right is the typical hosted AI inbox model.
