What our research says

Otter.ai

Still the default for English-language meeting notes, and the free tier is unusually usable. What determines the right plan is not features but the per-conversation ceiling: 30 minutes on Basic and 90 on Pro means a standard hour-long review truncates on the free tier and a workshop truncates on Pro. Pick the tier by your longest recurring meeting.

Pros

  • 300 free minutes a month makes evaluation real rather than token
  • Annual Pro at $8.33 is roughly half the month-to-month rate
  • An MCP server is exposed from the free tier, so assistants can query transcripts without the paid API
  • Business removes the minute cap entirely rather than raising it

Cons

  • The API and webhooks require Enterprise, which is quote-only
  • Per-conversation ceilings (30 min free, 90 min Pro) cut recordings mid-meeting
  • Basic allows three file imports in total, not per month
  • Month-to-month pricing is roughly double annual at both self-serve tiers

RollSummary

A good fit for a game master running a long-running campaign who is tired of writing session recaps by hand, since the auto-built wiki of NPCs and locations is the real value beyond a plain transcript. It is not useful for players, since only the GM needs an account, and the hour-based pricing means very long sessions cost noticeably more than short ones.

Pros

  • Auto-builds a searchable wiki of NPCs, locations, and plot threads rather than just a flat transcript
  • Free tier is generous enough for genuine trial use, a 30-day trial with six hours
  • Supports over 30 languages for transcription

Cons

  • Pricing scales with session length, so a marathon session eats a big chunk of the monthly hour allowance
  • Only benefits the GM directly; players get read access rather than their own tools
  • No stated company or founder information to gauge how established the product is

Which one fits

Choose Otter.ai if you need

  • Teams that live in Zoom, Meet or Teams and want notes without a note-taker
  • Accessibility use, where live captions matter as much as the transcript
  • Recruiters and researchers who need searchable interview records across a workspace

Choose RollSummary if you need

  • Game masters running long campaigns who want continuity tracked automatically
  • Groups who already record sessions and just want the after-session work automated
  • Tables playing in a language among the 30-plus supported rather than requiring English only
