ChatGPT and Claude can answer anything.
That's the bug, not the feature.
For actual learning, the tool that gives you answers is the tool that prevents learning. Cogniloop is built on the opposite principle: lock the AI into questioning, lock the UI into explanation, surface progress visibly so the learner can't lie to themselves.
Side-by-side
Use cases
FAQ
Why can't I just tell ChatGPT to be a Socratic tutor?›
You can. But you can also un-tell it in one prompt. The friction is wrong: ChatGPT defaults to answering, you have to fight it to drill yourself. Cogniloop defaults to drilling, you can't make it answer. The default is the product.
Claude has Projects with persistent memory now. Doesn't that solve it?›
Projects store text across chats. They don't show you a structured concept-mastery map, don't enforce a question-answer-evaluate loop, don't track streaks, don't render a final coaching report. Memory ≠ workflow.
Isn't this just a wrapper?›
It's a wrapper in the same sense Linear is a wrapper around a database, Superhuman is a wrapper around IMAP, and Notion is a wrapper around a rich-text editor. The win is product focus and locked behavior — same primitives, different game.
What LLM does it use?›
Default: Pollinations.ai's free public endpoint (openai / openai-fast / mistral — no API key needed). With a server-side GROQ_API_KEY set, it uses Groq's Llama 3.3 70B for higher quality and speed. Multi-provider with retry + automatic fallback.
What about hallucinations?›
Cogniloop doesn't generate explanations to feed you — it generates questions and grades your explanations. The model's hallucination surface is tiny. If your pasted notes are wrong, you'll be questioned on wrong stuff — but that's a content issue, not a tool issue. For high-stakes accuracy, paste your textbook content as notes.
Why are sessions client-side only?›
Privacy + simplicity. No login, no leak, no GDPR. You own your data, it never leaves your browser. The trade-off: clearing browser data deletes your history. Mark sessions to markdown if you want long-term storage.
When should I NOT use Cogniloop?›
When you want answers, not learning. When you're cramming raw facts (use Anki). When you need step-by-step solutions to homework (use a tutor or solver). When you need coding execution (use ChatGPT Code Interpreter or Claude with tools).
