Supermaven (supermaven.com) — AI Code Assistants

About Supermaven

Supermaven is an AI code completion tool that suggests code as developers type. The homepage says it uses a 1 million token context window and finds definitions elsewhere in the codebase to shape its suggestions. It works with VS Code, JetBrains IDEs, and Neovim.

The product also includes a chat interface for models such as GPT-4o and Claude 3.5 Sonnet, with hotkeys for viewing diffs and applying changes. The homepage lists a free tier and paid Pro and Team plans. Several features, including the 1 million token context window, are listed as Pro only. The free tier has a 7-day data retention limit. Pricing is not confirmed in this entry.
