TLDR

About TLDR

TLDR is an IDE plugin that explains code in plain English. The premise is that developers spend more time reading code than writing it, and that most of that reading is comprehension work a model can do faster: what does this regular expression actually match, what is this SQL query doing, what is happening in this function in a codebase nobody on the team wrote. TLDR sits inside the editor rather than in a browser tab, so the explanation arrives next to the code being read instead of requiring a copy-paste round trip into a chat window. It supports almost every programming language, and the vendor is explicit that the free tier exists so developers can try it against their own code before paying — the site says outright that it does not want to make promises it cannot keep. The free version is strictly rate-limited; paid tiers move to graceful rate limiting and add email support. Pricing is per user with a meaningful split between individual and organisational use, and both monthly and annual figures are published, with the annual rate working out to roughly ten months' cost. It ships as a JetBrains IDE plugin. For teams onboarding engineers into unfamiliar services, the codebase-comprehension use case is the strongest one on the page.
