Overview

Supermaven is an AI code completion tool for developers. It is positioned as a fast copilot for writing code in editors, with support for VS Code, JetBrains IDEs, and Neovim.

The product emphasizes high-quality completions for large codebases, including a 1 million token context window on Pro and Team plans. The site also presents Supermaven Chat as a companion workflow for discussing code, viewing diffs, applying changes, and fixing errors from the editor.

Features

AI code completion

Supermaven provides inline code completions and says it can help developers write code faster, with suggestions informed by the surrounding project context.

Large context window

The product advertises a 1 million token context window on Pro and Team plans, which is intended to help with larger codebases and broader project awareness.

Codebase-aware suggestions

The homepage shows contextual suggestions that reference definitions elsewhere in the codebase, indicating that completions can use project-wide code relationships.

Developer chat with edit actions

Supermaven Chat supports GPT-4o, Claude 3.5 Sonnet, GPT-4, and other leading models, with hotkeys for diffs, applying changes, starting conversations, and switching models.

File-linked chat workflow

The chat experience can attach recently edited files and link model responses back to the original code so users can view diffs and apply changes.

Error-fixing workflow

Supermaven can upload code together with compiler diagnostic messages in a single click to help fix errors from the editor.

Use Cases

Write code with broader project context
Use Supermaven while implementing functions, classes, or other editor changes when you want inline suggestions that draw on the surrounding repository rather than only the current file.
Review and apply code changes from chat
Use the chat interface when you want to inspect diffs, apply changes, switch between supported models, or attach recently edited files to a prompt.
Troubleshoot compiler errors
Use the error-fixing flow when compiler diagnostics are blocking progress and you want to upload code and error messages together from the editor.
Standardize access for a team
Use the product in a team setting when centralized user management and billing are needed alongside the Pro feature set.
Install from a supported editor
Use the VS Code install path if you want a direct editor setup flow that starts from the Extensions tab and enables the extension after reload.
