The short version

  • Each has a real cost: 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.; Terra the absence of a licence fee hides the real cost driver: an idle notebook virtual machine left running overnight, or a workspace bucket full of intermediate workflow outputs, quietly consumes grant money with no vendor invoice to prompt a review.
  • They diverge on capability: Marvin covers AI Notetaker, Terra covers No platform licence fee.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Marvin

  • A two-person research team that needs interviews transcribed, tagged and searchable without hiring an analyst or buying an enterprise repository.not Terra
  • A product organisation where findings are never read, wanting product managers to query past research from Claude or ChatGPT instead of logging into a research tool.not Terra
  • A team running discovery at volume that wants an AI moderator to conduct unmoderated interviews overnight and have them analysed by morning.not Terra
  • A researcher who needs to send stakeholders a highlight reel of customer quotes rather than a slide deck summarising them.not Terra

Terra

  • A genomics lab running whole-genome alignment and variant calling pipelines without provisioning or maintaining a local clusternot Marvin
  • A consortium sharing controlled-access human data across institutions where the data cannot be copied to each sitenot Marvin
  • A health system analysing patient genomic data under a HIPAA business associate agreementnot Marvin
  • A federal or federally funded project needing FedRAMP Moderate authorisation for its analysis environmentnot Marvin

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.

Terra

  • The absence of a licence fee hides the real cost driver: an idle notebook virtual machine left running overnight, or a workspace bucket full of intermediate workflow outputs, quietly consumes grant money with no vendor invoice to prompt a review.
  • Cost governance is entirely the customer responsibility, and grant-funded groups without a cloud engineer routinely overspend before anyone reads the Google or Azure bill in enough detail to find the cause.
  • It assumes genuine bioinformatics competence: writing or adapting WDL workflows, managing data tables and debugging failed tasks are all on you, so a wet lab without computational staff cannot use it productively.
  • Feature parity between the Google Cloud and Azure deployments is not identical, so a decision on cloud provider constrains which capabilities and datasets you can reach and is expensive to reverse later.
  • It is a research platform rather than a regulated clinical system: it is not a validated GxP environment and does not carry the qualification package a diagnostic or submission workflow would require, so clinical use needs additional infrastructure and validation you provide yourself.

Answered from the vendors’ own pages

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.

Terra: Is Terra really free?

The platform is. There is no licence fee. Everything you pay is Google Cloud or Azure compute, storage and egress, passed through at cost.

Marvin: What does Pro cost?

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

Terra: What actually drives the bill?

Running virtual machines and stored data. Pausing notebooks drops a virtual machine from about 0.22 to about 0.027 dollars an hour, and deleting intermediate workflow outputs is the other main saving.

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.

Terra: Can I use it with protected health information?

Yes. Terra signs HIPAA business associate agreements and GDPR data processing agreements, and the Azure deployment holds FedRAMP Moderate authorisation.

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.

Terra: Is it validated for clinical or GxP use?

No. It is a research platform. Regulated clinical or submission workflows need validation and controls you build yourself.
