The decision
Use-case anchors and category strengths, side by side.
Developers working on large, multi-file projects who want to parallelize their workflow. If you regularly work on 3-5 tasks simultaneously (fix a bug, add a feature, write tests, refactor), Antigravity's multi-agent architecture is unmatched.

Visit Otter.aiBottom line
Google Antigravity edges out Otter.ai by 0.5 points (8.0 vs 7.5) -- a A-tier vs B-tier split that's narrow but real. Not a blowout; both belong on a shortlist. The score gap shows up most clearly in the categories that matter for Google Antigravity's strengths, so if those categories are your priority, the lead translates.
Pricing-wise, both tools have a free tier (Google Antigravity starts $0, Otter.ai starts $0), so you can test either without committing. Compare what each free tier actually unlocks -- usage caps, model access, and feature gates differ a lot more than the headline price suggests, especially as both vendors have tightened limits in 2026.
By use case: pick Google Antigravity when developers working on large, multi-file projects who want to parallelize their workflow. Pick Otter.ai when remote teams who live in meetings and want automatic transcription, summaries, and searchable records. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in Google Antigravity's lane, the tier-list ranking and the use-case fit point the same direction; if you're in Otter.ai's lane, the score gap matters less than the fit.
Bottom line: Google Antigravity is the safer default for most readers, but Otter.ai is competitive enough that the tie-breaker is your specific workload, not the spec sheet.
