Studrix
Studrix is a Dutch web platform that turns a photo, a PDF, a Word file or pasted notes into an AI summary and a practice quiz, applying active recall and spaced repetition across secondary and undergraduate subjects.
What is Studrix?
Studrix is a web study platform built on a single premise: passive revision does not work. Re-reading and highlighting feel productive, the site argues, yet they barely move retention, so Studrix rebuilds the study session around four techniques taken from cognitive psychology, namely active recall, spaced repetition, interleaving and elaboration. Retrieval practice, it claims, is up to 50% more effective than re-reading.
The workflow has four steps. You upload material: a photo of a textbook page, handwritten notes, a text-based or scanned PDF, a Word document, pasted text, even a URL. OCR extracts the text, handwriting included. The AI then identifies the key concepts, definitions and facts, and returns a summary together with a quiz tuned to the subject and the level. You train on it with multiple choice, open, fill-in-the-blank and true or false questions, each carrying an explanation. Questions you got wrong resurface on a schedule, and one quiz can draw on several chapters or subjects at once.
Alongside quizzes, Studrix builds word lists with four training modes, Show Words, First Letter, Full Translation and Multiple Choice, which makes it as usable for vocabulary as for content subjects. A dashboard tracks words learned, quiz scores, study streaks, badges and weekly quests.
The audience is secondary school and first-cycle university, and the site says the coverage is optimised for the Dutch and Belgian curriculum. More than fifteen subjects are claimed, from maths and chemistry to history and languages, while the interface and the generated material run in seven languages: English, Dutch, German, French, Spanish, Italian and Polish. Dedicated pages cover quiz generation from PDF, summary generation and practice tests in biology and history, and mention GCSE, A-level, AP, IB and university material.
Studrix is delivered as a web application only: there is no native mobile app and no public API, and AI generation needs a connection, although reviewing an existing quiz works offline. Every AI operation consumes credits, OpenAI is named as the AI provider, and the publisher is Vuurpijl Beheer BV, a privately held Dutch investment company based in Spaarndam.

When to use Studrix / When not to
A quick filter to help you decide if Studrix is the right fit.
When to use Studrix
- Secondary school pupils revising for a test from their own chapter, notes or textbook photographs
- Undergraduates working through readers, journal articles and lecture slide decks exported as PDF
- Language learners who need vocabulary lists with four graded training modes and translation drills
- Students in memory-heavy subjects such as biology, history, geography, physics and chemistry
- Private tutors and test-prep coaches who want draft practice questions generated from a pupil's own material
When not to use Studrix
- Developers or product teams looking to embed study generation: there is no public API and no documentation
- Anyone who needs a native iOS or Android app, since Studrix runs only in a mobile or desktop browser
- Students who revise offline: quiz review works without a connection but AI generation does not
- Schools, universities and companies making an institutional purchase, with no DPA, subprocessor list, SSO or organisation plan
- Children under 13, who may not open an account at all, and under-16s without a parent or guardian's consent
How to use Studrix
A typical end-to-end flow, from setup to results.
- Try the public demo first, which generates three questions from a sample or pasted text without any account
- Create an account with an email address and a password, no card required
- Choose your native language and select the subjects you study, so translations and quizzes are calibrated
- Upload your material: a photo, handwritten notes, a PDF, a Word document, pasted text or a URL
- Let the OCR and the AI extract the text and identify the concepts, definitions and facts
- Read the summary that comes back, then open the quiz generated from the same material
- Answer the questions and read the explanation attached to each one, right or wrong
- Come back for the spaced review, where the questions you missed are presented again
- Split a long PDF into one quiz per chapter, and keep images sharp and well lit for reliable OCR
- Follow your progress by subject on the dashboard, and buy credits or a subscription when the free allowance runs out
Pros & Cons
Pros
- Questions and summaries come from the material you upload, which the site presents as the source of truth rather than a general model
- OCR covers photographs, handwriting and scanned PDFs, so little preparation of the source is needed
- The method is stated openly and mapped feature by feature onto four documented study techniques
- Pricing is low and displayed in full: from EUR 3.99 per month, or one-off packs from EUR 4.99
- Purchased credits never expire, and there is a permanent free plan plus a demo that needs no account
- No card is asked for at sign-up, cancellation is one click, and a 7-day money-back guarantee is advertised
- EU hosting is announced, with AES-256 encryption at rest and in transit and TLS 1.3 in transport
Cons
- No native application and no public API: everything happens in a browser
- AI generation is unavailable offline, only the review of an existing quiz works without a connection
- The credit system makes the real cost depend on volume, and the quiz-per-credit figures are given as approximations
- Traction claims such as 10,000 users, 50,000 quizzes and 95% satisfaction carry no source, and the testimonials cannot be verified
- The site contradicts itself on the free allowance, 50 credits in the FAQ against 1,000 credits on the demo page, and on the language count, seven almost everywhere but eight on the About page
- The legal documents are short and generic, with no figure for how long learning data is kept, no DPA and no subprocessor list
- Contact addresses are rendered as an image on the about, security and contact pages, so they cannot be copied

Data, GDPR & hosting
A consolidated view of how Studrix handles your data.
GDPR overview
Studrix claims GDPR compliance explicitly. Its security page carries a dedicated block, Full compliance with European data protection regulations and user privacy rights, and lists GDPR among its standards alongside PCI DSS and COPPA. The privacy policy, dated 31 August 2026, enumerates the rights of access, rectification, erasure, portability, restriction and objection, and the security page commits to answering privacy requests within 30 days as the GDPR requires. Most data can be changed from account settings; other requests go to the published privacy and information addresses. International transfers rely on adequacy decisions and standard contractual clauses, and Dutch law governs the terms. Two gaps remain: no Data Processing Agreement is published or offered, and no formal subprocessor list exists. No Article 27 representative or DPO is named, the publisher being established in the Netherlands.
Who owns the data?
Under the Terms of Service, users keep ownership of everything they upload, and Studrix takes only a licence to process that content in order to deliver the service. Users must hold the rights to the material they submit, and Studrix may remove content that breaches its policies. The homepage restates the principle plainly: your study materials belong to you, and you can delete your content at any time. Deleting the account itself is done from Settings and is described as permanent and irreversible. The platform, its features and its AI technology remain the publisher's intellectual property, and AI-generated output is supplied as-is for educational purposes only.
Reuse rights
Studrix states that it does not sell, trade or rent personal information. Data is used to deliver and improve the service, personalise study, generate quizzes and recommendations, track progress, communicate with users, secure the platform and meet legal obligations. AI processing covers content analysis, OCR on uploaded images, study-pattern analysis and natural language generation. Sharing is limited to service providers (payment, hosting, analytics), legal requirements, business transfers and cases of explicit consent. The security page states that no personal identification data is shared with AI providers, names OpenAI as the AI partner, and says OpenAI retains no data for this use case; the homepage adds that Studrix does not train public models on user notes. Because the material stays the user's own, a student may reuse their summaries and quizzes without asking permission; the terms set no restriction on that, while reminding that AI-generated content is provided as-is for educational purposes.
Data retention & training
Hosting summary
The homepage FAQ states that data is encrypted, EU-hosted in Frankfurt and never resold. The privacy policy describes encryption in transit and at rest, secure data centres, regular security audits and access controls, while the security page specifies AES-256 encryption, TLS 1.3 for communications, encrypted databases with access controls and audit logging, and multi-factor authentication. Network resolution places the site with Hetzner Online GmbH in Germany, which matches the announced jurisdiction, although the city differs from the one advertised. The privacy policy adds that information may be processed in countries other than the user's own, relying on adequacy decisions and standard contractual clauses. OpenAI is named as the AI provider, with temporary processing only and no retention for this use case, and the security page states that no personal identification data reaches AI providers. No hosting certification such as ISO 27001 or SOC 2 is claimed, and no subprocessor list is published.
Things to keep in mind
Risks and trade-offs to weigh before adopting Studrix.
- Outsourcing the work of summarising and questioning a chapter is exactly the effortful part that builds memory: letting the AI do it can hollow out the very retrieval practice the tool is selling
- The AI works from your document, but the terms warn that generated content may contain errors and ask you to verify anything important independently, which a student under exam pressure rarely does
- Revising only what the generator produced narrows the syllabus to what the model happened to extract, and a sparse slide yields a thin question
- Streaks, badges and weekly quests are engagement mechanics: they can drive daily habit, but they can also turn revision into score-chasing
- The promise not to train public models on user notes is narrowly worded and says nothing about internal models, and no training opt-out is documented
- Learning data may be kept longer than account data for service improvement, with no duration ever given, and no DPA or subprocessor list is published
- Three internal contradictions on the site, about the free credit allowance, the number of languages and refunds, should make you check the current terms before paying
Setup & Integrations
Technical difficulty
Very low. There is nothing to install: Studrix is a web application, and an email address and a password are enough to open an account. The demo runs without any account at all. The site says no prompt engineering or configuration is required, and recent versions of Chrome, Firefox, Safari or Edge are supported. The only practical constraint is the quality of what you upload, since OCR depends on a sharp, well-lit and reasonably contrasted image, and a long PDF works better split into one quiz per chapter. Multi-factor authentication is offered.

Should you pick Studrix?
Studrix is a focused consumer revision tool rather than a general assistant, and it says so itself: where a chatbot answers questions, Studrix takes a chapter and returns a structured summary, a retrieval-based quiz and a spaced review schedule. That framing is its strongest argument, and it is backed by an unusually explicit method, with each of the four study techniques it invokes mapped onto a concrete feature. The barrier to entry is close to zero, with a demo that needs no account, a permanent free plan, no card at sign-up and paid tiers that start at EUR 3.99 per month with credits that never expire.
The reservations are documentary rather than functional. The privacy policy, terms and cookie policy are short and generic; nothing states how long learning data is kept, no Data Processing Agreement is offered and no subprocessor list is published, which makes an institutional purchase difficult to justify. Traction figures and named testimonials carry no source. The site also contradicts itself in three places, on the free credit allowance, on the number of languages and on refunds, where a 7-day guarantee on the homepage sits next to a no-refunds clause in the terms. The commitment not to train public models on user notes says nothing about internal ones, and no opt-out is documented.
Behind the product is Vuurpijl Beheer BV, a small Dutch investment holding owned by one individual and running a varied portfolio, with no outside investors. The domain was registered in June 2025 and first archived in July 2025, so this is a recent product. For an individual student in secondary or early higher education, particularly on the Dutch or Belgian curriculum, it is inexpensive and easy to test. For an organisation, the compliance paperwork is not yet there.
