Use cases

Walking brainstorm

Talk through a strategy on a walk. Krater listens, asks questions, summarises when you get back.

Workflow

  1. Open Voice Mode: One tap from any chat. Pick your model. Start talking.
  2. Talk naturally: No wake word, no command syntax. Sub-second turn-taking, natural interruption.
  3. Switch modes any time: Move from voice to text mid-conversation. The chat history is unified — every word is searchable later.
  4. Save and revisit: Every voice conversation saves as a text chat. Come back to it tomorrow.
