AI meeting agent that transcribes, summarises, and turns every conversation into searchable knowledge
Live transcription in multiple languages with speaker identification, so meeting records are accurate and attributable.
Each meeting becomes a clear summary with decisions, action items, and insights, with next steps captured and assigned automatically.
Ask questions across your meetings and connected apps to instantly produce follow-ups, reports, and content.
Get briefing documents before a meeting and real-time, personalised coaching during calls based on your history and playbooks.

AI code review that runs your app on every pull request
TestDriver reviews every pull request automatically, reads the diff with its vision agent, and generates end-to-end tests straight from the PR content to prove the new behavior works.
Tests run your actual application in a real desktop sandbox—clicking, typing and reading the screen—so they catch runtime and visual bugs, not just code diffs.
When the UI shifts and a cached element no longer matches, the AI finds it again, updates the cache and continues, so tests survive redesigns without rewrites.
Once a test passes, TestDriver opens a fresh pull request with the generated Vitest test code committed, so coverage lands in your repo alongside the change it protects.
