TLDR

TLDR is an IDE plugin that uses AI to explain code in plain English. A developer selects a method, query or expression and receives a short summary of what it does, which helps build mental context quickly when reading unfamiliar code. It is distributed as a JetBrains IDE plugin, and the vendor says it supports almost all programming languages. The site highlights three uses: explaining regular expressions, which are hard to read at a glance; explaining SQL queries and how they work; and getting oriented in a new codebase. Selected code is sent to the vendor's servers, where it is processed to produce the explanation. It suits developers who read a lot of code written by colleagues or inherited from others, and teams onboarding onto large projects. Pricing is handled through JetBrains and is shown monthly or annually. The Free plan costs $0 and comes with limited API credits and strict rate limits. The Individual plan is $4.90 per user per month or $49 per user per year, with gentler rate limits and email support. The Organization plan is $9.90 per user per month or $99 per user per year, with gentler rate limits and priority email support. The vendor encourages trying the free version on your own code before buying.
