Keldr is a voice assistant for your everyday work.

You see exactly what it's about to do before it goes out, and there's a record of everything afterwards.
Just say it.
Keldr does it.
Hold ⌃ space and talk like you would to a colleague. Keldr drafts the email, the task, the follow-up — and shows you what it'll do before it does it.
