An Otter alternative for your ideas — not just your meetings
Otter is a heavyweight for meeting transcription and team notes. But if you tried it to catch your own fleeting ideas, it can feel like renting a conference room to write a sticky note. Thought Spark is built for the solo idea — capture it, sharpen it, research it, and act on it.
Free to capture on iPhone · No meeting bots, seats or team setup
Short version: Otter is a meetings-and-teams transcription platform. Thought Spark is a personal idea-development app. Different jobs — use Otter for calls, use Thought Spark for the ideas you want to actually take somewhere.

Where Otter shines
Otter is genuinely excellent at what it's for. Live transcription during calls, speaker identification, searchable meeting archives, and sharing with a team — if your job involves a lot of meetings, it's a category leader for a reason.
Otter is great when…
- You need meeting transcripts and summaries
- You collaborate with a team
- You want real-time captions during calls
…but for personal ideas it's a lot
- Built around meetings, not two-second thoughts
- No AI interview to develop a raw idea
- No open-web research on what you captured
Where Thought Spark fits
Thought Spark isn't trying to replace Otter in the meeting room — it's for the ideas that strike outside it. Tap once, speak or type, and the idea is captured with a title and tags. Then take it further:
- Clarify — a short AI interview sharpens the idea into something you can act on.
- Research — one tap checks it against the web and returns findings with real sources.
- Act — concrete next steps drop into Apple Reminders and Calendar.
No bots to invite, no seats to buy, and your notes stay on your device.
For the ideas between the meetings
Catch it, sharpen it, research it, schedule it — free to start on iPhone.
