Edubrain
Edubrain is a web-based AI homework helper that turns a typed question, photo, PDF, scan or audio recording into a step-by-step worked solution across 90+ subjects. The free tier requires no sign-up and no card.
What is Edubrain?
Edubrain is a web-based AI study assistant published by PIXELLA RISE LTD, a Cypriot company. Its core is a homework solver that occupies the home page: you drop in a typed question, a photo, a scan, a PDF or an audio recording, pick a subject from roughly seventy-five options, and press Start solving. No account, no card and no configuration are needed for that path; signing in exists only for billing and for ordering human help.
The tool accepts up to 10,000 characters of text, files up to 32 MB and audio up to 25 MB, in txt, pdf, doc, png, jpeg and jpg, one file at a time. What comes back is an answer plus a decomposed line of reasoning with mathematical formulas rendered legibly, and you control the register: a quick final answer, a detailed walkthrough, or a correction of work you have already done. Follow-up questions revise the answer already on screen instead of starting over.
Around that solver sits a wide catalogue. There are generators for flashcards, revision notes, quizzes, presentations and answers; a research assistant and a lecture note-taker; an AI detector, humaniser, paraphraser, summariser and plagiarism checker; seven diagram builders covering flowcharts, mind maps, pie and radar charts, sequence diagrams and timelines; ten citation generators including APA, MLA, Chicago, IEEE and Turabian; and roughly twenty dedicated mathematics calculators. Dozens of per-subject pages run from linear algebra to political science, against a claim of 90+ subjects.
Distribution is freemium. A permanent free tier is funded by advertising; AI-Plus removes the advertising and unlocks advanced reasoning for USD 3.99 per week — a weekly, not monthly, cycle. A separate human service, Expert help, is quoted per project. The interface is genuinely localised into eight languages.
What the site does not document is the technical layer: no hosting location, no statement on whether submitted work trains models, no retention period, no processing agreement and no certification. Its own honour code frames the intent — aid comprehension, not supply work to hand in.

When to use Edubrain / When not to
A quick filter to help you decide if Edubrain is the right fit.
When to use Edubrain
- Students stuck on an exercise who want the reasoning laid out, not just the final answer
- STEM undergraduates working through calculus, physics, chemistry or statistics problem sets
- Anyone revising for exams, who can upload past papers, midterms and whole problem sets
- International students, who get an interface in eight languages and can submit a question in their own
- Teachers assembling chapter quizzes, flashcard decks and lesson notes between classes
When not to use Edubrain

- Students who mean to hand the output in as their own work, which the publisher's honour code explicitly forbids
- Organisations with compliance obligations: no processing agreement, no subprocessor list, no certification, no data-location commitment
- Developers wanting to embed the tool: there is no public API, no mobile app and no third-party connector

- To subscribe or to order human help, sign in on the my.edubrain.ai sub-domain; to cancel, email support
Pros & Cons
Pros
- Immediate access with no account and no card, including downloading and sharing results
- A permanent free tier with no stated attempt limit, advertising being the trade-off
- Photo, PDF and audio input, so there is no need to retype an exercise
- Very low paid entry point at USD 3.99 per week, and an unusually broad toolset for that price
- Identifiable publisher: company name, Cypriot registry number HE 477434, registered office, governing law and courts all agree
- Four distinct contractual documents published, including an honour code that frames academic use
- Interface genuinely translated into eight languages, with localised URLs page by page
Cons
- Nothing published on hosting: no country, no region, no provider
- No statement on whether submitted work is used to train models, and therefore no documented opt-out
- No quantified retention period — data is kept "as long as we need to"
- Unusually broad licence over submitted content: perpetual, irrevocable, transferable, sub-licensable, including the right to sell
- Weekly subscription that renews automatically, is expressly non-refundable, and can only be cancelled by email
- A single email address serves support, legal and privacy, and it is obfuscated in the page source
- Audience figures and review scores contradict each other from one block of the site to the next

Data, GDPR & hosting
A consolidated view of how Edubrain handles your data.
GDPR overview
The publisher is established in Cyprus, so the GDPR applies directly and no Article 27 representative is required or named. The privacy policy is explicit rather than merely present: it names the GDPR, states the legal basis relied on (legitimate interests), lists six data subject rights — access and rectification, erasure, objection, restriction, portability, and complaint to a local supervisory authority — and undertakes, where data leaves the EEA, to protect it "to a level that meets the EU requirements". Beyond that the framework is thin. No data protection officer is designated, no response deadline is given, no retention period is quantified, no processing agreement is offered and no subprocessor list is published. Rights are exercised through a single general mailbox rather than a dedicated form, and no certification such as SOC 2 or ISO 27001 is claimed anywhere on the site.
Who owns the data?
PIXELLA RISE LTD retains ownership of the site and of every deliverable produced by its human experts; you receive only a limited, non-transferable licence for personal and educational use, which terminates the moment you breach the terms. Content you submit remains yours in name, but you grant the company a non-exclusive, perpetual, irrevocable, transferable, fully sub-licensable, worldwide, royalty-free licence to use, modify, publish, translate, sell and create derivative works from it in any medium. You are also asked to waive your moral rights and never to contest changes. Because the licence is sub-licensable and transferable, unnamed third parties may exercise the same rights.
Reuse rights
On the free tier you may download every response — answers, presentations, flashcards — and share them with others without asking permission; both are listed as plan features. Expert-made deliverables are narrower: the licence covers personal and educational use only, so you may not share them, resell them or present them as your own work, and it terminates on breach or after a successful chargeback. As for what the company does with your data, the privacy policy says it collects voluntarily supplied details (email, name) plus automatically captured identifiers (hostname, IP address, cookie ID, session time), relies on legitimate interests as its legal basis, may email or message you for marketing, and may transfer data outside the EEA. Third-party cookie vendors are named — Google Analytics, Google Dynamic Remarketing, Google AdWords, Facebook products, Hotjar — but the list closes on "etc.". Note that the about page claims no personal data is collected at all, which its own privacy policy contradicts.
Data retention & training
Hosting summary
Nothing is published about where data is hosted. No country, no region, no provider and no data centre is named anywhere on the site, and there is no trust or security page. The only related statement is in the privacy policy, which allows for data being shared with and stored by third parties in jurisdictions outside the European Economic Area, notes that those jurisdictions may not offer equivalent safeguards, and treats continued use of the site as consent to that transfer. Against it the policy sets a general, unquantified undertaking to protect transferred data "to a level that meets the EU requirements". One technical signal should not be mistaken for a hosting location: the domain resolves to Cloudflare anycast addresses, which identifies a content delivery network edge, not where the data actually lives. The publisher itself is established in Cyprus, which places the controller inside the European Union, but that says nothing about server location.

Things to keep in mind
Risks and trade-offs to weigh before adopting Edubrain.
- Academic risk: handing in an output as your own work breaches the publisher's honour code, and the terms disclaim all responsibility for plagiarism, lost scholarships, lost grants or poor grades
- Learning risk: a tool that returns a finished solution in seconds makes it easy to stop doing the intermediate reasoning yourself, and to mistake having read an explanation for being able to reproduce it under exam conditions
- Accuracy: the terms warn in capitals that outputs may be incorrect and may be identical for different users, and place the burden of verification entirely on you
- Billing: the weekly subscription renews automatically, is expressly non-refundable even on early cancellation, and can only be cancelled by email; any unused account balance is wiped after six months
- Content rights: the licence you grant over anything you submit is perpetual, irrevocable, transferable, sub-licensable and worldwide, includes the right to sell and to create derivative works, and comes with a request to waive your moral rights
- Mixed messages on privacy: the home page promises an anonymous environment where files are deleted as soon as processing ends, but no contractual document repeats that undertaking, and the about page's claim that no personal data is collected is contradicted by the privacy policy
- Contradictory numbers: usage figures and review scores differ from one block of the site to the next, so treat the social proof with caution
Setup & Integrations
Technical difficulty
Essentially none. Edubrain is a web tool: a browser is all you need, with no installation, no registration, no card and no configuration for the free AI path. The only choices are the subject and the answer style. The site says a first answer takes seconds — the about page mentions ten seconds of analysis, and the reviews page claims first answers in under a minute. An account is required only to subscribe or to order human help. There is no API key to obtain and no connector to configure.

Should you pick Edubrain?
Edubrain is a working product rather than a landing page. The solver runs on the home page without an account, the tool catalogue is genuinely built out across a hundred or so internal pages, and the publisher is identifiable: PIXELLA RISE LTD, Cypriot registry number HE 477434, with a registered office, governing law and competent courts that all agree. Four separate contractual documents are published and prices appear in plain sight. For a student who wants a worked explanation from a photo of an exercise, at no cost and with no sign-up friction, the offer is unusually direct.
The reservations are documentary rather than existential. Nothing on the site says where data is hosted, whether submitted work is used to train models, or how long anything is kept; there is no processing agreement, no subprocessor list and no certification. The licence taken over submitted content is unusually broad — perpetual, irrevocable, transferable and sub-licensable, including the right to sell — and users are asked to waive their moral rights. The paid tier bills weekly, renews automatically, is expressly non-refundable and can only be cancelled by email. The terms require users to be 18 while the marketing addresses schoolchildren, and they forbid use altogether from England and Wales, Ireland, Australia and New Zealand. The site's privacy-first claim is contradicted by its own privacy policy, and its audience figures and review scores disagree from one block to the next.
Read it as a low-cost explanation engine for individual learners who will check the output — the publisher's own honour code says as much — rather than as a tool for any setting where data handling has to be contractually pinned down.
