Free for 300 new lines a month. $10 a month for no limit.
Zoom in when it gets big

Search finds any line, wherever it sits.
Share a line
Send someone a link to one line. They see that part of your list and nothing else.

On your phone too
The same list on your phone and your computer, saved as you type.

And you can add your bots
If you use an AI coding agent or write your own scripts, they can work your list with you. Each bot signs in as itself, reads the list, adds its own lines and checks off what it finishes.
When a bot wants to change one of your lines, it asks first. You watch all of it on one page.
The Agent Harness is $50 a month.
Your bots, your tools
A bot adds a line the same way your page does: one small call, with its own login.
POST /api/lines/launch/enter
PATCH /api/lines/new-line/text
PATCH /api/lines/new-line/done
Start with a plain list. Bring your bots when you are ready.
Free for 300 new lines a month. No card needed.
