“Why is this container restarting?”
docker logs --tail 200 <id> + the likely cause, risk-rated, one click to copy.

Speak once.
It already knows where you are.
Press ⌥ Space in any app. Smarn reads the window you're looking at — the terminal, the error dialog, the email thread — and answers in place. No copying, no tab-switching, no re-explaining.
Free during early access. Everything you capture stays on your Mac.

The problem
Every AI micro-task costs six hops.
A question the model answers in five seconds takes thirty to sixty seconds of copying, switching, pasting and re-explaining — and breaks your flow every single time. The assistant doesn't know what's on your screen, so you become the clipboard.

How it works
Bring the AI to the context, not the context to the AI.
Trigger
⌥ Space, or hold Right Option to talk.
Capture
Front window, selected text, terminal buffer — plus a screenshot read on-device.
Ask
Type or speak. Capture is already done before you finish.
Answer
Streamed into a small overlay as typed blocks: command, code, draft, steps.
Act
Copy, insert, or run — behind a deterministic risk gate. Nothing runs without you.
Capture is taken from the window that was frontmost before the overlay appeared. Smarn never screenshots itself, and a screenshot alone can't give you exit codes or scrollback — so it captures structured context first and uses vision to fill the gaps.
Use cases
Built for people who live in a terminal, a browser and a mail client.
Build or test failurecode
“Why is this failing?”
The stack trace read off your screen, an explanation and a fix — or a hand-off to Claude Code with the right cwd.
Browsertext
“Explain this section simply.”
Uses your selection if you made one, otherwise the visible page. Cites the part it used.
Any error dialogsteps
“How did I get here and how do I fix it?”
Screenshot + on-device OCR of the modal → diagnosis and copyable steps.
Maildraft
“Reply saying we can do Thursday, keep it short.”
A draft in the thread's tone, ready to paste.
Memorysearch
“That Postgres vacuum thing I read last week?”
Search everything you've captured — by app, by text on screen, by date. No AI needed.
Local memory
Google Photos, for everything you've seen.
Every capture you ask about is kept on your Mac — the image and the text on it — and indexed for search. Type whatsapp and every WhatsApp screenshot appears. Type half an error message and find the moment you saw it.
- ● Search runs on-device. No AI, no upload, no account.
- ● Only redacted text is stored — keys and passwords never touch the disk.
- ● Forget any capture, or everything, in one click. ⌥ ⇧ Space to open.

Privacy, by construction
Nothing leaves your Mac without you knowing.
Captures only when you trigger it
No always-on recording. No background memory. Pixels are read the moment you ask — never before.
Reads on your Mac
Screenshot OCR and speech recognition run on-device with Apple's frameworks.
Scrubs secrets first
API keys, tokens and passwords are redacted in the Rust core before anything leaves the machine.
Sends only to your AI account
The captured context and your question go to the provider you connect, under your own key and its terms. Never to us.
Never runs commands on its own
You click Run. A deterministic risk gate — code, not a prompt — decides what may run at all.
Memory never leaves the machine
Your captures are files and a database in your own Library folder. Delete them whenever you like.

Put it on your Mac.
Early-access build. Signed and notarized. Bring your own Anthropic API key — it's stored in your Keychain and only ever used to make the request.
