Recall
Turn your lecture PDFs into practice exams. Claude writes multiple choice, single choice, fill-in-the-blank, long answer and code questions from your material, then grades your answers with feedback.
It runs on your own computer and uses your Claude Pro or Max subscription through Claude Code. No API key, no extra billing, and your files never leave your machine except to be read by Claude.

Features
- Works for any subject: maths, engineering, nursing, science, business, law, humanities or computing. Claude writes questions the way an examiner in that field would.
- Five question types: multiple choice, single choice, fill in the blanks, long answer, and artifact questions.
- Artifact questions: Claude shows you something to work with, chosen to suit the material: equations to solve or derive, a graph to read and interpret, a data table (lab results, patient observations, financial figures), a case study or clinical scenario, or code to explain, trace or debug.
- Proper maths: equations are typeset everywhere (questions, options, answers and feedback). Type maths on a keyboard (
x^2, sqrt(2), 3.2e-4) and Claude accepts any equivalent form, with method marks for correct working.
- Combine lectures: build one exam from several PDFs. Claude spreads the questions across them and cites the document and page for each.
- Exam or practice mode: answer everything and submit, or check each answer as you go.
- Focused quiz view: one question at a time, with a question navigator, mark-for-review, a timer and keyboard shortcuts. A single-page view is also available.
- Autosave: unsubmitted answers are kept in your browser, so a refresh or closed tab doesn't lose work.
- Grading and feedback: objective questions are marked instantly. Written answers are marked by Claude against a rubric, with covered and missed points. Results show weak topics to review.
- Any Claude model: Sonnet, Opus, Fable, Haiku or a specific model ID, with adjustable effort.
- Text or Visual reading: Visual mode lets Claude look at the pages themselves, for scanned slides, diagrams, graphs and equations shown as images.
- Viva practice: paste a GitHub repository link (public or private) or upload a zip of your project, and Claude reads the code, then examines you on it in a text-based viva. It asks one question at a time, follows up on your answers and quotes your code. At the end you get a score and feedback for each topic. Progress is saved, so you can leave and come back, and you can retake a viva.
- Light and dark themes, renameable materials and sets, and attempt history with score trends.
Quick start
You need Node.js 22 or newer and Claude Code.
# 1. Install Claude Code and sign in with your Claude account
npm install -g @anthropic-ai/claude-code
claude auth login
# 2. Install and run Recall
npm install
npm run dev
Open http://localhost:3000. The first time, a welcome page checks that Claude Code is installed and signed in, and shows how to fix anything missing. It only appears once; to see it again, delete data/onboarded.json. Setup help is always at /setup.
There is no Recall account or sign-in. It's open source and runs entirely on your computer.
