Supermaven
The fastest copilot with a 1-million-token context window
Supermaven is the first AI code completion tool to offer a 1-million-token context window. Created by Jacob Jackson (founder of Tabnine), it uses a proprietary new neural network architecture designed for ultra-low latency. It remembers literally every file in your project, allowing it to suggest code based on definitions and patterns from across your entire codebase instantly.

Pros and Cons
Advantages
- The 1-million-token context window is a game changer for large projects
- Noticeably faster (lower latency) than GitHub Copilot or Cursor's autocomplete
- Works exceptionally well in Neovim and Sublime Text
- The free tier is surprisingly generous with context size
- Code suggestions feel more cohesive with the rest of the project
Disadvantages
- Chat UI is more basic compared to Cursor or Windsurf
- Lacks "Agentic" capabilities (cannot run terminal commands or create files autonomously)
- Proprietary model (Babble) might be less "knowledgeable" about general trivia than GPT-4o
Best For
Developers working in large codebases where context matters
Neovim and Vim users who need speed and low latency
Users who prioritize "autocomplete" speed over "chatbox" features
Those dissatisfied with Copilot's latency or context limits
