The short version

  • Only Marvin has a free tier, so it costs nothing to try first.
  • 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.; TetraScience pricing is scoped on connected instruments and data engineering effort rather than a published unit, so the cost of adding a new laboratory or an acquired site is impossible to forecast without going back to the vendor.
  • They diverge on capability: Marvin covers AI Notetaker, TetraScience covers Instrument connectors.
  • 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 TetraScience
  • 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 TetraScience
  • A team running discovery at volume that wants an AI moderator to conduct unmoderated interviews overnight and have them analysed by morning.not TetraScience
  • A researcher who needs to send stakeholders a highlight reel of customer quotes rather than a slide deck summarising them.not TetraScience

TetraScience

  • A pharmaceutical company trying to make twenty years of chromatography data usable for modelling rather than trapped on instrument workstationsnot Marvin
  • A biotech building machine learning models on assay data that currently requires manual export from every instrumentnot Marvin
  • A quality control laboratory needing instrument data captured with provenance and audit trail for regulated usenot Marvin
  • A company consolidating data from acquired sites where each site runs a different instrument vendor and informatics stacknot 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.

TetraScience

  • Pricing is scoped on connected instruments and data engineering effort rather than a published unit, so the cost of adding a new laboratory or an acquired site is impossible to forecast without going back to the vendor.
  • Value depends entirely on connector coverage for your actual instrument estate; an instrument type without an existing productised connector becomes a services engagement with its own timeline and cost.
  • The GxP package is a separate annual subscription rather than an included capability, so a company that starts in research and later needs regulated use faces an additional commercial line and a validation exercise.
  • It is infrastructure with no end-user application of its own, so the business case rests on downstream analytics and AI work that has to be resourced and delivered separately before anyone sees a benefit.
  • Deployment is a multi-year programme touching instruments, networks, validated systems and site IT, and organisations consistently underestimate the internal effort required from people who also have day jobs running the laboratory.

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.

TetraScience: What is the pricing unit?

Connected instruments and the scope of data engineering, over a fixed contract term. There is no published per-seat or per-gigabyte rate.

Marvin: What does Pro cost?

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

TetraScience: Does it replace my ELN or LIMS?

No. It sits underneath them, harmonising instrument data and making it available to whatever applications you already run.

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.

TetraScience: Is it usable in a GxP environment?

Yes, with the separately subscribed Tetra GxP package. It reduces validation effort substantially but does not eliminate your validation obligation.

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.

TetraScience: Can I get the harmonised data out?

Yes. Tetra Data is designed to be accessible to your own analytics tools rather than confined to the platform.
