Didja

---

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 is a Mac menu bar app that notices those steps for you:

• Catch. Checklists Claude writes for you, commands to run, and "don't forget" lines in email and chat become open items in the menu bar, grouped by where they came from.
• Watch. As you work, it looks for proof each step is done: the right variable on the right settings page, the command run in a terminal, the reply actually sent.
• Tick, or ask. When it is sure, it ticks the step. When it isn't, it asks. A step left hanging gets one gentle reminder.

It works in the apps you already use: Claude, Claude Code in a terminal, ChatGPT, Gemini, Copilot, Codex and other AI tools, Gmail, Outlook, WhatsApp, Teams, Slack and any browser tab. You can also connect Linear, Jira, Asana, Todoist or Notion.

Download

Download the latest release (a signed and notarised .dmg).

• macOS 14 or later, on Apple silicon.
• Didja asks for Accessibility to read the window you are working in. Screen Recording is optional, and is only used for apps that hide their text.
• Didja checks for updates once a day. You can turn this off in Settings › General.

Privacy

It reads your screen, so it never sends any of it anywhere.

• On your Mac only. Reading, matching and the language model (Apple's on-device model, or a model you run in Ollama if you turn that on) all run locally. No account, no cloud, no analytics.
• Text, never pixels. It keeps short pieces of text. No screenshots or video are ever stored.
• Forgets in 24 hours. Captured text is deleted after a day at most. Your task list stays.
• Skips the sensitive stuff. Password fields, password managers, private windows and anything on your exclude list are never read.
• Pause any time from the menu bar or with ⌃⌥P.

The only network traffic is the daily update check and, if you connect them, your task tools. Settings › Privacy in the app shows what is read, what is kept and where, with the live state of each. The full detail is in docs/GUIDE.md.

Build from source

You need Xcode 16+ and Bun.

# engine tests and type-check
cd engine && bun install && bun test && bunx tsc --noEmit && cd ..

# build the app (bundles the engine) and run the Swift tests
xcodebuild -project app/Didja.xcodeproj -scheme Didja -configuration Debug -derivedDataPath app/build test

open app/build/Build/Products/Debug/Didja.app

The project signs with the maintainer's Apple Development team. To build without that certificate, add CODE_SIGN_IDENTITY=- CODE_SIGN_STYLE=Automatic DEVELOPMENT_TEAM= to the xcodebuild command. macOS will then ask for Accessibility again after every rebuild.
