Personal one-on-one AI tutor for any subject (calculus, organic chem, Spanish, constitutional law, programming, history, anything). Pick a TEACHING MODE: explain it / Socratic question-led / step-by-step worked example / practice problems with answer key / exam-prep flashcard sheet / debug-my-thinking / ELI5. Set your level (elementary through PhD). The tutor adapts vocabulary, gives concrete examples, names common mistakes, and offers practice. Conversation mode keeps history in localStorage so you can drill down across many turns.
Khanmigo (Khan Academy) is $4/month — Socratic by default, K-12 focus. Tutor.com runs $40-160/month. Wyzant is $35-65/hour for human tutors. Chegg Tutors is $14-50/month plus $30+/hour. Free.ai's tutor is free, available instantly, covers any subject through PhD level, and has 7 distinct teaching modes — no booking, no waiting. Trade-off: AI cannot grade your handwritten work the way a human can, and it WILL occasionally hallucinate factual claims, so verify safety-critical material.
Yes — Qwen 3 30B on our GPUs. A standard 500-word tutor response costs about 500 tokens. Free signup gets 10,000 tokens — ~20 sessions. Premium models (Claude Sonnet, GPT-5, DeepSeek R1) are sharper for STEM reasoning and worth the swap when stakes are high.
(1) Explain — direct walk-through with examples + analogies. (2) Socratic — tutor responds with leading questions, you find the answer (deepest learning, slowest). (3) Step-by-step — fully worked example, every step shown. (4) Practice — 5-10 problems at your level + answer key. (5) Exam prep — high-density review sheet (concepts / formulas / mistakes / tactics). (6) Debug my thinking — paste your work, tutor finds the specific step you got wrong. (7) ELI5 — explain like I am 5, no jargon, one familiar analogy.
Conversation mode keeps a rolling 8-message history in localStorage. The next question you ask references the prior context, so you can drill down ('but what if x', 'walk me through that step again'). Toggle off for one-off questions. Click Clear conversation to wipe history.
Sometimes yes — that is the nature of LLMs. The system prompt forbids inventing citations or 'studies show' filler, but factual claims about specific dates, papers, or statistics should be verified independently. For STEM problem-solving, the math is usually correct; for humanities and rapidly-evolving fields, double-check. DeepSeek R1 + premium models hallucinate less.
7 levels: Elementary (Grade 1-5), Middle school, High school, Undergraduate, Graduate / Master's, PhD / specialist, Self-taught hobbyist. The system prompt adapts vocabulary, depth, and example complexity to the level you pick. Switch levels mid-conversation if your initial pick was off.
Yes — paste the problem in the question box. Use 'Step-by-step worked example' mode for math/physics, 'Debug my thinking' if you have an answer that came out wrong, or 'Socratic' if your teacher requires you to show your own work. The Socratic mode will not just give you the answer.
Yes — choose response language (English, Spanish, French, German, Portuguese, Japanese, Chinese, Hindi, Arabic, or Auto = match your input). Useful for non-native speakers studying in their second language, or polyglot students learning math in their L1 even though their textbook is L2.
No — first session free. Sign up for 10K tokens, generation history, premium models. ~20 sessions per signup grant. Conversation history persists in your browser whether or not you sign up.
It's a general-purpose LLM, not a kid-curated product. Parental supervision recommended for under-13. The Elementary level keeps language age-appropriate and avoids adult themes, but no content filter is perfect. Khanmigo is a better choice for unsupervised K-8 use.
Yes — POST to /v1/chat/ with the tutor system prompt (in template source) plus the conversation messages array. Useful for ed-tech apps, LMS plugins, or homework helpers. Bearer auth, monthly limits. Docs at /api/.
