Natural language search surfaces internal libraries and existing patterns. This helps prevent stale code, dependency bloat and frees up time to work on unsolved problems. Making it easier to discover internal APIs improves adoption and reduces duplication. bloop’s natural language search returns accurate results in less time, making it a powerful alternative to slow keyword searches and asking colleagues for help. bloop understands your codebase. When responding to natural language searches, complex concepts are summarised and the intention behind code is explained. You can follow up a natural language search with a codebase change. This is ideal for small changes and can be initiated by anyone on the team, regardless of coding ability. Precise code navigation in 10+ languages helps you move quickly through refs and defs.
