The short version

  • Only Marvin has a free tier, so it costs nothing to try first.
  • Each has a real cost: Attest pricing is metered by credits, where one credit equals one survey question answered by one person, rather than a flat per seat rate; 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.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Attest

  • Pricing is metered by credits, where one credit equals one survey question answered by one person, rather than a flat per seat rate
  • The Basic tier caps usage at 50,000 credits; going beyond it requires upgrading to Standard (100,000), Elite (200,000) or a custom plan above 400,000
  • Additional credits purchased mid year cost 10 percent more per credit than the plan rate

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.

Answered from the vendors’ own pages

Attest: How does Attest's credit system work?

Attest uses a credit-based pricing system where one credit equals one survey answer from one respondent. For example, a 10-question survey completed by 500 people uses 5,000 credits. Only respondents who meet survey criteria consume credits from the qualifying question.

Marvin: Is there a genuinely free plan?

Yes. Two full seats, three collaborator seats and five file uploads a month at no cost. It is enough to evaluate the analysis quality on real interviews.

Attest: What plans does Attest offer?

Attest offers four subscription plans: Basic (up to 50,000 credits), Standard (up to 100,000 credits), Elite (up to 200,000 credits), and Custom (over 400,000+ credits). All plans include unlimited user seats, designated research expert, customer success team support, and access to 150+ million consumers across 59 countries in 70+ languages.

Source
Marvin: What does Pro cost?

Not published. Only the Free tier carries a price. Starter, Pro and Enterprise are all quoted.

Attest: Can I purchase additional credits on Attest?

Yes. Additional credits are available as add-ons throughout the year. Add-on credits cost 10% more than the per-credit rate in annual plans.

Source
Marvin: Can I get SSO and EU data residency?

Yes, but as a separately priced Compliance add-on from Pro upwards, not included in any base tier. Price it into the quote from the start.

Marvin: What is the MCP server for?

It lets Claude, ChatGPT or Copilot query your research repository directly with cited answers, so stakeholders get findings without opening Marvin.
