Otis lives on your Mac and runs your mail, meetings, docs and browser by voice. Want it to work differently? Say so, and Otis rewrites itself to fit you.
Meetings
Otis listens to the call from your Mac: the call app's sound and your mic. It transcribes on your Mac as people talk, with names from your calendar. During the call it flags questions and facts worth checking. When the call ends you get a summary of decisions, open questions and next steps with owners and dates, plus a follow-up email drafted and waiting.
Dictate
Tap the mic and speak. Your words appear in the message box as you talk, and Otis keeps listening through pauses until you tap Send. On iPhone it uses the phone's own speech recognition, with punctuation, and you can start it from the lock screen, Control Center or Siri.

One list of everything that needs your tap: approvals, drafts, sign-ins and reviews. Otis checks each item first and closes what is already done.
QueueEach morning your to-do list fills from your mail, calendar and meeting notes. When an item is done, Otis closes it and says why.
To-dosOtis browses in its own tabs, signed in as you, while your tab stays in front. When a page needs you, it hands it over.
BrowserOtis is not a password manager. It fills your sign-ins from the one you already use, after one Face ID or Touch ID tap, and never sees the password.
Sign-insWrite together with comments and tracked changes. Otis suggests edits you accept or reject, and Word files go in and out.
DocsSpreadsheets with formulas, formatting and comments. Import and export Excel and CSV files.
SheetsDecks you comment on slide by slide, mark up with a pen, and present. Export to PDF or PowerPoint.
SlidesAt 6 a.m. Otis writes a briefing on the topics you set, with sources. It skips what you already read and reads it aloud.
BriefingA coach built on your Strava runs and Garmin health data: today's workout for the time you have, a weekly plan, readiness and trail routes.
CoachSee the Claude Code sessions on your Mac from your iPhone, with new replies marked. Open one to read its thread, then reply by voice or text, photos included. Your reply goes into the running session, or resumes it if none is running.
SessionsA chat app waits for you to type. Otis keeps working on your own computer, and you reach it wherever you are.
Otis runs on your own Mac, day and night. Long jobs run in the background while you keep talking. Your files and memory stay on your machine.
Talk from your iPhone with the screen off, from AirPods in the car, or from a button on your earbuds. Otis knows your voice, and only your voice can give it a task.
Ask for something Otis cannot do yet. It writes the code, tests it and ships it, usually while you carry on. If you do not like it, one tap undoes it.
Each of these runs today.
A short read on the news you care about, with sources. Tap Listen and Otis reads it aloud.
Articles, PDFs and posts in a natural voice, with skip, speed and a to-read list.
Otis checks new mail through the day and offers Draft reply, Remind me or Add to calendar. Drafts land in your Drafts folder.
A live transcript, a summary at the end and a follow-up email, drafted and waiting.
Write docs, sheets and slides together. Otis leaves comments and suggested edits you accept or reject.
A short round of A or B picks. Otis keeps the rules you choose and follows them from then on.
Otis runs its full test suite every night and tells you in the morning if a change needs undoing.
You say what you want. It plans the change, writes it on its own branch, runs the tests and merges it. You get a card with Details and Undo.
Your agent grows around how you work, not around a product roadmap.
Most of Otis was built by voice, by its first user.

Learns you
As it works, Otis notes the calls it made that you never ruled on. At 8 p.m. it asks a few as quick A-or-B picks, about two minutes. Your picks become rules that every chat and task follows. Otis tests a rule on past cases before it keeps it, and you can keep, change or drop any rule.
It also remembers. Each night Otis saves the day's decisions and preferences, and it searches that memory and past conversations before it says it does not know.
Under the hood
Otis is a set of Claude agents on your Mac, wired into your voice, your files and your day.
Ask for a change and Otis writes the code on its own branch. A test gate runs before every merge, and a failed test blocks it. Every merged change has a one-tap Undo.
Up to 16 background agents run at once: 12 for research and writing, 4 for code. Each code agent works in its own isolated git worktree, so changes never collide.
A fast voice model (Claude Sonnet) starts answering as it streams, with read-only access to your calendar, tasks, docs and memory. Anything that needs action goes to the full agent (Claude Opus on Claude Code).
Whisper runs locally on Apple silicon. Dictation turns into text in 0.34 seconds, and your audio never leaves your Mac.
Each night Otis distils the day into dated facts and a summary. It searches that memory and past conversations before it answers.
One agent, reached from the Mac app, iPhone, Siri, iMessage, earbuds, an e-ink tablet and smart glasses.
Otis does most work on its own. It never sends, deletes, signs in or buys until you say so. Each one waits in the Queue with one clear button.
Waiting for you
Otis runs on your computer. Its memory is plain files you can open and read.
Sign-ins fill from your own password manager after Face ID or Touch ID. Otis sees the result, never the password.
Mail and texts arrive as drafts. You send them.
Demo mode lets friends try Otis with no access to your memory or files.
Otis comes from Caloa Professional Services Inc., a small security consultancy in Squamish, BC. Its builder runs a working week on Otis and asks it for a new feature most days. It is in private testing now, and we are opening a few more spots.
Otis carries the name of a good dog: loyal, steady and on your side.
A Mac that stays on and online, and an iPhone. Otis lives on the Mac, so think of it as a small home server for your agent. The iPhone, earbuds, Messages and an e-ink tablet are ways to reach it.
Otis keeps its memory, files and settings on your Mac. To think and speak, it sends your requests to the AI model it uses (Claude, from Anthropic). It does not sell or share your data.
It works on its own for most things: drafting, reading, researching, writing documents, building features. Sending, deleting, signing in and buying always wait for your tap.
Otis needs its Mac awake to work. Keep it plugged in with sleep turned off, and Otis is there around the clock.
Each request becomes a background task on its own branch. Otis writes the change, runs the tests and merges it only when they pass. Every change has an Undo.
We have not set a price. Early-access testers will hear first, before anything is charged.
Not yet. Otis is built for macOS and iPhone first.
Early access opens in small groups. Leave your email and we will write when your spot is ready.
