I want a sales CRM with a pipeline by stage, my contacts and what's due this week

After that, just ask: “add the phone number to the customer record”.
Five apps that work together.And a builder for whatever's missing.
What you write down becomes a task, the task shows up on your calendar and the daily summary pulls it all together. You never copy anything from one place to another.

6 videosRecorded in the real theo. The people and numbers in the videos are examples.
A second brain that works while you live.
It starts with a conversation to get to know you: your work, the people, your routine. Then it reads your Gmail and calendar, read-only, and handles what you don't have time for.
Daily summaryBefore you open your email, the day is already summed up.
Meeting prepWho'll be there, what you talked about last time and what's still open.
Email triageSeparates what needs you from what can wait.
After the meetingRecord the conversation. It writes the minutes and creates the tasks.
Memory of peopleEvery person and every project with its history, in your MyNotes.
You're in controlNothing leaves theo without your OK. Everything it does has Undo.
From morning coffee to the end of the day, nothing slips.
A sample Thursday. Each step uses a different app, and none of them makes you copy anything.

Ask Claude. theo does it.
Connect theo to Claude once and just ask: it queries your apps, writes in your MyNotes and files everything in the right place — in the chat, the app or the terminal.
Your apps. “How many orders are late?” It reads the app's tables and answers — and only changes the rows you point to.
MyNotes. Minutes, proposals and summaries: it writes, edits just the part you asked for, and builds databases, mind maps and diagrams.
With your permission. The connection only exists after you click Allow on theo's screen, and you can disconnect anytime in Settings → Connections.
