Submergent brings Claude, ChatGPT, Copilot and more into one desktop app that works with the files you already have. Bring the plans you pay for. Your work stays on your machine.
Available on Mac. Windows and Linux coming soon.
Did the new onboarding actually move engagement? Compare people who signed up before and after it launched.
Yes, clearly. Since the new onboarding shipped, weekly active users are up 18% and new people come back more often in their first week.
The lift is biggest for teams of 5–20 people. Want me to turn this into a one-page summary for Thursday’s review?

Introducing Submergent
Submergent gives every AI you use one home on your computer. Point it at a folder, ask in plain words, and get real work back: a summary, a chart, a rewritten doc. Switch models mid-thought without starting over. Nothing you do is uploaded to us.
What it does
No prompts to engineer and nothing to install beyond the app. Talk to it the way you'd brief a sharp colleague.
Pick any folder on your computer. It reads your docs, spreadsheets and notes where they are, so there's nothing to upload and nothing to copy back.
When a chart says it better, you get a chart. Live pages appear right in the conversation, ready to expand or share.
Start a second task while the first is still thinking. A quiet dot tells you when one is done or needs you.
01Merge the three pricing docs into one outline02Rewrite the FAQ in plain language03Save a draft next to the originals for reviewAsk for a plan first and nothing gets touched until you say go. You decide how much it can do on its own, and it asks before the rest.
Continuous context
Use Claude to think it through, ChatGPT to draft it and a local model to tidy up. The conversation moves with you, so you never explain the task twice.
Help me plan the launch email. Who is it for, and what's the one thing they should do?
Trial users who haven't invited a teammate yet. One action: invite someone. Lead with the hour it saves them each week.
Perfect. Draft it in under 120 words.
Done. Saved as launch-email.md next to your brief. Subject line: “Your team's first project, in two minutes.”
Tightened it to 96 words and kept your subject line.
Use cases
Tell Submergent what you do the first time you open it. It shows what you need and keeps the rest out of the way.
Privacy and control
Submergent runs on your computer. Your account with us is for licensing the app, not for storing what you do in it.
Chats, files and history live on your computer, in app data you can inspect and delete. Your work is never uploaded to us.
What you send goes from your computer to the AI you picked, under its terms. We don't sit in the middle or keep a copy.
Crash reporting stays off unless you turn it on, and even then it never includes prompts, files or paths.
Choose how much it can do alone. Anything beyond that waits for your OK, one action at a time.
Runs locally, in folders you choose, with the AI plans you already have.
