Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Marvin

  • Transcription is inconsistent, with missing punctuation and specifically poor Portuguese accuracy reported, so non-English research teams spend the time cleaning up that the licence was meant to save.
  • Speaker diarisation errors attribute moderator speech to the participant, and a misattributed quote propagates into themes and into the insight report you show stakeholders, which is a research credibility risk rather than a cosmetic bug.
  • SSO, EU or US data residency, PII redaction and a HIPAA BAA are bundled into a paid Compliance add-on available only from Pro upwards, so the headline Pro quote is never the real price for a regulated or European buyer.
  • Starter includes only two full seats, so a four-researcher team is forced to Pro on seat count alone, and the three-way split between full, collaborator and viewer seats makes cost modelling awkward when no paid tier is priced publicly.
  • Every paid tier is sales-gated with annual commitment typically required, so there is no monthly paid trial and no published seat cost to budget against before entering a sales cycle.
  • Integration coverage has gaps, with no Intercom connector despite repeated requests from teams wanting support conversations in the same repository, and reviewers describe the tags versus labels distinction in the interface as confusing.

Otter.ai

  • Two separate limits apply at once, a monthly minute allowance and a per conversation cap, so a long meeting can be cut short with allowance remaining
  • The free plan cuts off at 30 minutes per conversation and 300 minutes a month
  • The Pro plan still caps a single conversation at 90 minutes
  • Even unlimited plans cap a conversation at 4 hours
  • Imported file transcription has its own separate monthly limit, at 6,000 minutes on Business
  • Paying monthly rather than annually roughly doubles the rate, from $8.33 to $16.99 on Pro
