vo.id vs Otter
Otter is built for meetings: it joins your calls, transcribes them and answers questions about them. The void is built for the thoughts you have between meetings, the ones nobody else was there for.
Otter is an AI meeting assistant that joins Zoom, Google Meet and Teams calls, transcribes and summarizes them, and offers an AI agent that can answer questions and take follow-up actions from your meeting history.
just you, on purpose
No bot joins your calls and nothing records the people around you. The void hears only what you choose to tell it, and voice memos are capped at ten minutes on every plan because it's built for one thought at a time, said on purpose.
you stay in charge
Nothing in the void acts in the world without you. A memo goes to TickTick or your calendar when you send it there, or when you've turned on automatic sending for that kind of action yourself.
capture by text as well
Text a memo to your void number from any phone without opening an app, or record or type on the web. Voice memos are transcribed for you.
chat with your notes
Ask a question across everything you've captured and get an answer that links to the memos it came from.
privacy
There are no ads and no trackers. Your memos are encrypted at rest, never used to train a model, and never sold or shared, and the privacy page lists exactly what goes to the AI.
when Otter is the better pick
If you need meeting transcripts, summaries and a shared record for a team, use Otter. The void deliberately doesn't record meetings or anyone but you.
