Key features	Plain-English explanations of selected code Runs inside the IDE rather than a browser Supports almost all programming languages Quick summaries of unfamiliar functions Free tier to try	AI-generated plain-English PR descriptions from diff analysis Simplified summaries for non-technical stakeholders Weekly progress reports across all changes Public changelog sharing with JSON API No local code storage - reads via GitHub/GitLab API
Pros	Shortens the orientation phase when reading unfamiliar code In-IDE placement means it actually gets used Broad language support rather than one ecosystem	Removes a genuine, widely-felt friction point (writing PR descriptions) Free tier covers a meaningful volume (~10 PRs/month) before paying Doesn't store code locally - reads directly via API
Cons	Explanations can be fluent, plausible and wrong about the edge case that matters Orientation aid, not a substitute for reading the code Check your employer's policy before sending proprietary code to any service	Token-based pricing means heavy PR volume requires a paid tier quickly Unused tokens don't roll over between billing cycles AI-written descriptions still benefit from a human sanity check on accuracy
