It's been a while since my last WiseSloth update — and the project has kept quietly growing. Today, WiseSloth.app has passed 2,500 registered users, who have created more than 10,700 tests spanning 27 languages. Behind those tests sit over 248,000 AI-generated quiz questions and 400,000+ answered quiz results. I went back to the live site to write this properly — here's what the platform actually does today, how it works, and what's coming next.
The big picture
WiseSloth turns any text into study material. Paste your lecture notes, upload a PDF, drop in an old exam — the AI generates a complete multiple-choice quiz in seconds. No formatting required, no templates to fill: it reads the content and writes questions that match the level you ask for.
The whole site is bilingual (English/Spanish), works on phones, and is free. Anyone can create, take, and share tests; there's also a community of public quizzes — searchable by topic and language — plus an optional Premium tier for the heavy users.
How creation works
From the home page you pick between two groups: a Quiz / Test or a Flashcards deck. For quizzes there are three generation styles:
- From an old exam — paste the exam and it produces a similar quiz, questions and options included.
- From notes — your class notes become a full quiz, keeping the important concepts.
- From scratch — describe the topic, audience and style ("for 16-year-olds, include true/false") and it writes the quiz for you.
You control the details: number of questions (up to 50), difficulty, language, and an optional skill that shapes the AI's behaviour (e.g. "always explain with diagrams and visual mnemonics"). The generated quiz can be edited question-by-question, and there's an AI edit tool to rewrite, rephrase or improve individual questions or whole decks.
Taking a quiz
The quiz player is clean and mobile-first: one question at a time, four options, instant feedback, and a progress bar. LaTeX math renders inline (great for stats and engineering subjects), and at the end you get a clear result summary with your score, plus per-question review of what you got right or wrong.
Beyond solo study
A test page gives you Try (take it), Battle (real-time duel with friends — same questions, faster correct answers score more, Kahoot-style), Share, and PDF / DOCX export so you can print or reuse the quiz offline.
The community keeps a growing library of public quizzes — from psychological statistics to medical history — searchable by language and topic, and you can follow authors and like tests. Flashcard decks flip card-by-card with a focus mode for quick review sessions.
What's next: open source and bring-your-own-key
Two things I'm particularly excited about:
1. Making WiseSloth open source. The plan is to publish the codebase (Express + FastAPI + MySQL + Redis) so anyone can self-host their own quiz-generation platform — and so the community can contribute features, languages, and model integrations.
2. Bring-your-own AI API key. Soon, users will be able to plug in their own LLM API keys and generate quizzes on their own account — giving power users control over models and costs while keeping the free tier simple for everyone else.
If you haven't tried it yet: wisesloth.app turns any text — old exams, notes, articles — into engaging quizzes in seconds. Free, no card required.
