Supermaven is an AI-powered code completion tool and copilot designed for software developers, founded by Jacob Jackson (co-founder of Tabnine and former OpenAI researcher). Supermaven differentiates itself with extremely low latency and a 1-million-token context window powered by its proprietary 'Babble' model, allowing it to understand long sequences of code. The product offered IDE plugins for editors such as VS Code, JetBrains, and Neovim. In November 2024, Supermaven was acquired by Anysphere (the maker of Cursor), and its standalone product was sunset on November 30, 2025, with its technology integrated into Cursor's Tab completion feature.
