Catch
Didja spots checklists, setup steps and "don't forget" lines as they appear, and turns each one into an open loop.
Didja finish that?
Ten tabs, four Claude sessions, one forgotten step.
You're vibe coding in five places at once. Claude gives you a checklist, you do three steps, a new prompt pulls you away, and step four quietly disappears, until production breaks.
Didja remembers the steps you didn't finish, and ticks them off when you do.

Looks done — confirm? New email to Mike seen in Gmail

THE ZIGZAG
Out of sight, out of mind. Then it breaks.
You jump between chats, dashboards, inboxes and tabs all day. The step you didn't finish doesn't wave at you. It just scrolls away.
- 1
You get a checklist.
Claude gives you four steps to ship to production. Or Sarah writes: "Don't forget to email Mike."
- 2
Something pulls you away.
You finish step three. A ping, a new prompt, the next email. You move on.
- 3
Step four is gone.
Production breaks. Mike never got the email. Didja would have asked.
HOW IT WORKS
Catch. Watch. Tick.
No setup, no integrations to connect. Install it and it works in every app you already use.
[SCREENSHOT: env var page showing STRIPE_KEY → task ticks with evidence]
Watch
As you work, it looks for proof each step is done: the right variable on the right page, the email actually sent.
[SCREENSHOT: "Looks done — confirm?" and a nudge for a step left behind]
Tick — or ask
Sure? It ticks it off. Not sure? It asks. A step left hanging gets a gentle nudge, not a siren.

Questions
Is Didja free?
Yes. Didja is free and open source.
Does anything leave my Mac?
No. Everything runs locally. If you choose to turn on an optional AI helper for tricky items, only a short redacted snippet is sent, and only with your say-so.
Why does it need Accessibility and Screen Recording permission?
Accessibility lets it read the text of the window you are working in. Screen Recording is only a fallback for apps that hide their text, and frames are read and dropped immediately.
Windows?
Mac first. Windows is on the roadmap.
