Don’t say “let me check.” Just answer.

A Mac app that answers questions about your own product during calls, from your code, docs and past calls, with sources, and hands what you promised to Claude Code or Codex.

They’re built to write good notes after the meeting. Stuart is built to answer during it, from your code and docs, with the source. It writes a transcript and a summary too, but that isn’t the reason to use it.

You can, and it works well for looking things up after a call. But a notetaker doesn’t know your code, and Claude Code doesn’t hear your call. Stuart does both while you’re still talking: it answers from the repos, docs and past calls you picked, with the source, keeps each promise with the person you made it to, and hands it to Claude Code afterwards.

Both help during calls. Stuart answers from your own work and shows where every answer came from. It never hides from screen share, and it gives you a line to tell the other people it’s there.

Only if you share your whole screen. Stuart never hides, so what’s on your screen is what they’d see. Share a single window instead, or choose “Quiet for this call” so answers stop appearing at the top of your screen.

In many places you have to tell people a call is being transcribed, and in some places everyone has to agree. Stuart gives you a line to say at the start, or to paste into the meeting chat with one tap: “I’m using Stuart to take notes on this call. Tell me if you’d rather I didn’t.” Using it within the rules where you and the other people are is up to you. Our consent guide covers the basics.

No. Point it at your docs and notes and it answers from those. It’s strongest when it can also read the code your product is built from.

Every answer shows where it came from, so you can check before you say it. Each sentence has to point to a real source from your work, and a sentence without one is removed. If Stuart can’t find anything solid, it says “Not sure” instead of guessing. Sources can be out of date, so each one is a click away.

It’s built to stay light. The model Stuart uses to search your work takes about 240 MB of memory. The first time you ask something, it downloads a 151 MB model that ranks what it found; that one uses about 320 MB while it works and is unloaded after 10 idle minutes. Calls are kept as text; the audio isn’t saved.

Stuart is in early access. Leave your email on this page and we’ll email you the day Stuart for Mac is ready to download.

Code repos and their git history, Claude Code, Codex and Cursor sessions, folders of docs and notes (Markdown, text, PDF), Obsidian and Logseq vaults, Apple Notes and your Mac’s calendar if you allow them, and the calls Stuart listened to. It reads from your Mac. It doesn’t connect to your email or chat apps.

Some things do, and we’d rather say exactly what. What Stuart has read of your work stays on your Mac. When you ask a question, only the excerpts that answer it are sent to Stuart’s service, which passes them to the AI model and doesn’t store them. On a call, audio or transcript lines are sent the same way. Your account email, the name of each Mac you sign in on, usage counts and billing state are stored. The privacy policy has the full list.

No. Stuart doesn’t train models on your data. Stuart uses Google’s paid Gemini API. Under its terms, Google doesn’t use prompts or responses to improve its products. Google keeps them for a limited period only to detect abuse. Web searches send only the short search query to Brave Search, which keeps a record of it for up to 90 days for billing and abuse prevention.

A Mac with Apple silicon and macOS 15 or later. On macOS 26, English calls are transcribed on your Mac. On earlier versions, and for other languages, Stuart’s service transcribes them. There’s no Intel or Windows version.

No. What Stuart reads stays on your Mac, but writing answers needs Stuart’s service, so you need a connection.

Each plan has one monthly allowance for Stuart’s cloud features: answers, talking to Stuart, help during calls, summaries and transcribing calls in the cloud. Stuart shows it as one percentage in Settings, with a note if you’re on pace to run out. If you use it up, those features pause until the 1st of next month (UTC), and your calls keep being saved on your Mac. You’re never charged extra. To keep going before the reset, upgrade to Pro or Max, or add 3× Free’s allowance for $10 for the rest of the month, from the app.

Cancel anytime in Stuart under Settings, Account, Plan. You keep your plan until the end of the period you paid for. Ask within 14 days of your first payment and you get all of it back; the refund policy has the details, or write to hello@stuartdesk.com.
