Now taking early seats

A second brain that's already thinking before you are.

tentus captures what you read, hear and write — then hands it back with every claim cited to your own material. No filing. No folders.

How the line works

Seats open in order. Sharing moves you forward.

Access opens in small groups so every early user gets a real reply from a real person. The list is the only way in.

01

Get in line

One email. You get a position and a personal link — nothing else, because nothing else would be used yet.

02

Pass the link along

Send it to the person you know with too many notes and no system for them.

+1 place per confirmed signup
03

Your seat opens

One email with your way in. Free while you evaluate.

What's inside

It captures. It recalls. It arrives prepared.

Most tools stop at storage and ask you to be the librarian. tentus does the librarian's job so you can do yours.

01 — Capture

Friction is the enemy.

Talk, paste, drag, clip. Gmail, Calendar, Drive and Slack feed in on their own.

  • Voice memos transcribed and indexed
  • No tags, no folders, no decisions at capture time
02 — Lumi

Answers from your own material.

Ask a question, get an answer with the sources it drew from — your notes, your calls, your history. Not the internet.

  • Every claim cited
  • Says it doesn't have something rather than guessing
03 — Ready before you ask

It arrives prepared.

What you owe whom, what you're walking into, and the patterns it noticed across the week.

  • Delivered before your first meeting
  • Sharper the longer you use it
Questions

The short answers.

When do seats open?

In small batches. Your position decides your batch, and you get one email when it's your turn.

What does it cost?

Nothing while you evaluate. Pro is $12/month. Joining from this list makes it $10/month for your first 12 months, and $12 after that. Everything you put in is exportable whether you pay or not.

Where does my data go?

Into your own workspace, encrypted at rest. Lumi only reads what you've connected and never trains on your material. Disconnect a source and its content goes with it.

Does it replace my notes app?

It can. It doesn't have to — tentus is happy sitting alongside Notion or Obsidian and reading from them.

Start thinking with a quieter notebook.

Get in line now. Move up by sharing.
