What it does
Everything custom apps can do
What you type is kept
Everything you add is a record: saved on every computer you use, taken back with Undo, and kept in the trash for 30 days when deleted. A board holds up to 2,000.
Your agents read and change the records
Claude, Codex or Grok can read every record and add, change or remove them. The app shows each change at once, and Board activity says who made it.
Change it by asking
Ask for a filter, a new field or an easier way to add, and your agent changes the app. Your records stay as they are.
Sealed off from the internet
The app runs in a frame of its own with no network, so it can’t send your records anywhere. You can read and edit its code.
Copy it as a new board
Duplicate keeps the app and its records. New board from this gives you the same app, empty, for the next client or the next quarter.
Ask your agents
What to ask each agent
You ask: Build me a studio onboarding tracker: each studio, its plan, and four steps to live
An app that fills the board, with a row for each studio
You ask: Northwind had its setup call. Move it on and note that it waits on group bookings.
Northwind at First class, with the note
You ask: Add a filter by plan
A Studio Plus chip beside the stage chips
Also try Claude: “Which studios are still at Signed up?”

Frequently asked questions

Setup, connections and every limit are in the docs.
What can I build?
Any tool that keeps a list of things: a content pipeline, a client intake, a review queue, a tracker for your spending. Describe it, and your agent writes the app that fills the board. Ask again to change it.
Is what I type saved?
Yes. Everything you add is a record, saved on every computer you use, with Undo. A deleted record waits in the trash for 30 days. A board holds up to 2,000 records.
Can my agents use the records?
Yes. Any agent connected to Context Board can read the records and add, change or remove them, and the app shows each change at once. Board activity says which agent made it.
Can the app reach the internet?
No. It runs in a frame of its own with no network, so it can’t fetch anything or send your records anywhere. You can read and edit its code.
Can I share it?
Not yet. A Custom board holds your own tool and its records, so it is not shared by link. You can duplicate it, or start a new board from its app.
What does it cost?
Context Board is free for 3 days, then $12 a month for the whole workspace: custom apps, dashboards, docs, sheets, plans and every other kind of board. The board’s chat runs on the Claude or Codex plan you already pay for.
One workspace for you and all your agents
Custom apps sit beside dashboards, client pipelines, sheets and every other kind of board, in one workspace your agents work in with you.
