Each one below started as a concept from an Anthropic course and became something you can actually touch — try the mini version right here, or open the full tool. New ones get added as I build them.

Handing a task to AI works a lot like delegating to a new hire: you'd decide upfront what they handle alone, what needs your sign-off, and what you're accountable for either way. This framework turns that instinct into four short questions you answer before you ever open a chat.
Answer one question below, and see how it becomes the start of a real, usable prompt.

From Markov chains guessing off the last word alone, to transformers weighing everything you've written so far — the method changed, but the game stayed the same: predict what comes next, one token at a time. Seeing how each generation actually guesses makes it obvious why fabrication concentrates exactly where specifics run out.
Pick an algorithm generation, and see how differently it guesses the next word.
Push one dial hard, and see what it does to the resulting prompt.
Pick a metric, and see how it judges "The car is fast" vs. "The vehicle is quick" — zero shared words, same meaning.

Anyone can write a skill on a resume. What actually convinces someone is a specific, checkable example — something they can click on. This tool walks a claim through four steps: sharpen it into one honest sentence, plan where the proof will live, then verify it's the kind of thing real people would actually confirm.
Pick a skill you'd claim, and see it turned into the start of a proof-hunting prompt.
Pick an opening line, and see one of the mechanical checks it runs before you post.
Pick a question, and see the kind of gap it would flag before rewriting it.
Pick a paragraph pair, and see the kind of relationship it would flag before any fact-check happens.
Pick a paragraph type, and see whether it even belongs in the fact-check queue.
