Release notes

1.0.2

  • Transcribe meetings. A new toolbar button captures a meeting for as long as it runs — transcribed live, minute by minute — and saves the transcript as a file attached to the chat, ready for "summarize this" or "what were the action items?"
  • Conversations keep their depth: a quick "why?" after a hard answer stays on the stronger model instead of dropping to a lighter one.
  • Attached documents and photos now follow the conversation for a few turns, so follow-up questions don't need re-attaching.
  • Regenerate and Think harder quietly teach the router which answers fell short.

1.0.1

  • Closing the window no longer briefly freezes the app when macOS's permission service responds slowly — menu-bar status checks are instant now.

Verify your download in K.ai

Every release ships with a signed manifest. If you have K.ai installed, verification is a drag and drop — no Terminal. Download these three files to the same folder:

Then open K.ai, choose File → Verify Download…, and drop the files into the window. K.ai checks the PGP signature against the release key built into the app, hashes the DMG byte for byte against the signed manifest, and answers plainly: Signed By, Release Hash, Verified — ready to install.

Verify in Terminal instead

Install GnuPG (brew install gnupg or the official download), download the files above plus our public release key, then:

cd ~/Downloads
gpg --import kai-release-public-key.asc
gpg --verify K.ai-1.0.2-manifest.txt.asc K.ai-1.0.2-manifest.txt
shasum -a 256 -c K.ai-1.0.2-manifest.txt

You want Good signature from Dan Ostermayer <dan@alohak.ai> and K.ai-1.0.2-arm64.dmg: OK. Confirm the key with gpg --fingerprint dan@alohak.ai against:

3F7E 7740 37BA 41E0 70D9 130B 3928 1EE7 5977 E465

PGP proves who signed the manifest; SHA 256 proves the DMG matches it; notarization is Apple's independent third check.
