What is Curie?
Assistant for scientific literature and document analysis - answers verified against the papers they cite. Curie: literature answers with receipts Curie’s promise is rigor over fluency.
Our verdict
Curie treats scientific literature as ground truth: it searches PubMed, arXiv, Europe PMC, OpenAlex and Semantic Scholar in parallel and verifies every claim against its source. A real free plan, transparent per-tier limits and a GDPR-compliant EU home from a University of Barcelona research group make it an easy recommendation to try.

Curie: literature answers with receipts
Curie’s promise is rigor over fluency. Ask in plain language and it searches PubMed, arXiv, Europe PMC, OpenAlex and Semantic Scholar in parallel, then verifies every claim against the paper it came from. The vendor says gaps are stated, not smoothed over – the right posture for a research tool, and the one worth testing first on the free plan.
From question to systematic review
Beyond Q&A, Curie uploads your own PDFs and DOCX files for cross-document extraction, keeps a taggable library, and runs full systematic reviews with a PRISMA diagram from the Starter tier up. The limits are refreshingly explicit: ranked results per answer and requests per minute published for every tier.
Academic roots, commercial ambiguity
Curie is built by Biost3, a research group at the University of Barcelona, with EU hosting, GDPR compliance and a no-training-on-your-data pledge. The wrinkle: the August 2026 legal

Academic roots, commercial ambiguity
Curie is built by Biost3, a research group at the University of Barcelona, with EU hosting, GDPR compliance and a no-training-on-your-data pledge. The wrinkle: the August 2026 legal notice calls it a non-commercial research prototype awaiting legal review, while the pricing page sells USD 19 and USD 49 subscriptions. Neither is hidden, but buyers should know the legal scaffolding lags the checkout flow.
Pricing
The free plan is usable: 300 chat requests a minute and 50 ranked results per answer. Starter (USD 19/mo) multiplies that roughly 20x and unlocks full PRISMA reviews; Pro (USD 49/mo) triples Starter; Team is custom with per-member budgets. Annual billing saves about 20%.

How we tested
Ashley Richmond desk research September 30, 2026. Official pages reviewed: curieai.tech home, /pricing, /about, /legal, plus the Product Hunt listing (curie-4) used to confirm identity among several unrelated Curie products. No account created, no documents uploaded, no purchase. CSV categories Productivity; Education; Artificial Intelligence map to ai-assistants + industry education.

Key features
Parallel search across 5 scientific databases
Curie searches PubMed, arXiv, Europe PMC, OpenAlex and Semantic Scholar in parallel, returning up to 100 ranked results per answer on Starter (200 on Pro).
Claim verification on every answer
Every claim is checked against its source paper; per the vendor, if Curie cannot verify something it says so instead of hiding it.
Document upload and analysis
Upload your own PDF, DOCX, TXT or MD files and extract data across them - sample sizes, outcomes, yields - per the vendor.
Full systematic reviews
Run complete systematic reviews with a PRISMA diagram included, from Starter upward.
Library with tags and export
Save, tag and export articles in a built-in library.
Plain-language questions
Skip keywords and boolean filters: ask the way you would ask a colleague and Curie works out what to search.
Extract Data workflows
Dedicated Extract Data feature for pulling structured fields out of study sets.
GDPR-compliant, EU-hosted
Servers in Europe, GDPR compliant, and the vendor states user data is never used to train models or shared with anyone.
Key benefits

- A working free tier lets you test Curie on a real question from your own research before paying.
- Academic roots: built by the Biost3 research group at the University of Barcelona, GDPR compliant and EU-hosted.

Pros & Cons
Pros
- Verification-first design: claim checking on every answer, and the vendor says Curie admits gaps rather than papering over them.
- Real free plan: 300 chat requests/min and 50 ranked results per answer at USD 0.
- Transparent, per-tier limits (requests per minute, ranked results, usage multipliers) published on the pricing page.
- Strong privacy posture: GDPR compliant, EU servers, no training on user data, pseudonymization (vendor-stated).
Cons
- Legal status mismatch: the August 2026 legal notice calls Curie a non-commercial research prototype to be reviewed before any commercial launch, yet the pricing page sells USD 19/49 subscriptions.
- Academic project, not a company: no legal entity, founding year or named founders published - the responsible party is a university research group.
- Rate-limited by design: usage is capped in requests per minute, which can throttle heavy batch work even on paid tiers.
- Young product with a single review on Product Hunt at review time - limited independent validation.

Frequently asked questions
Is Curie free?
Yes, there is a working free plan: search across all 5 databases with claim verification, 50 ranked results per answer and 300 chat requests per minute at USD 0. Starter is USD 19/mo, Pro USD 49/mo (+ VAT; annual saves ~20%), Team is custom.
Which databases does Curie search?
PubMed, arXiv, Europe PMC, OpenAlex and Semantic Scholar, searched in parallel, per the vendor.
How is Curie different from a general chatbot?
The vendor's pitch is verification: answers are built from the actual papers and every claim is checked against its source, with stated gaps instead of confident filler. It also runs full systematic reviews with PRISMA diagrams.
Who is behind Curie?
Biost3, a research group at the University of Barcelona (Av. Diagonal 643, Les Corts, 08028 Barcelona). Contact is support@curieai.tech. No separate company entity or named founders are published.
Is my research data safe?
The vendor states Curie is GDPR compliant, hosted on European servers, never uses your data to train models, and does not share user data with anyone. These are vendor-stated policies, not independently verified.
Is Curie a commercial product?
Mixed signals: the pricing page sells Starter and Pro subscriptions, but the legal notice (last updated August 17, 2026) describes Curie as a non-commercial research prototype that should be reviewed by legal counsel before any commercial launch. Worth knowing before a team-wide rollout.
