From a sentence to a link.
01
Say what you want
One sentence in plain words. Bool writes the app and the database behind it.
02
It's live at its own address
A real website the moment it builds. Send anyone the link.
03
Choose who gets in
Anyone with the link, everyone at work, or only the people you name.
You bring the idea. Bool writes the code, sets up the data, and gives it a live link.
Everything an app needs is already there.
Data and files
Every app gets its own database and file storage. Browse and edit the rows yourself.
Sign in for your users
Accounts for the people who use your app, with nothing to set up.
AI inside your app
Summaries, chat, tagging. Ask for it in plain words. No API key.
Undo anything
Every change is a checkpoint. Roll back to any version, publish when it's ready.
Build it together
Invite people by email and edit side by side. Editors don't need a plan.
