Fine is an AI coding agent that works asynchronously in an isolated development environment. It uses integrations with tools like GitHub and Sentry to gather full context about your codebase and uses advanced LLMs (e.g., o1, Claude 3.5 Sonnet) to generate, test, and refine code autonomously, then creates pull requests (PRs) for human review before merging.

What are the main features?

The main features include building new apps or websites from natural language prompts, editing, refactoring, or adding features to existing codebases, automating PR reviews, summaries, and revisions, running, testing, and previewing code live, and collaborating via a chat-like AI interface, issue trackers (GitHub, Linear), and Slack (private alpha).

Fine builds a real-time knowledge graph called "Atlas" from your connected repositories and external tools data, providing a rich context that enables the AI to give hyper-personalized answers and accurate code-related assistance such as explanations, bug fixes, or feature additions.

Is Fine fully autonomous?

Fine acts as a highly independent AI team member but never pushes changes directly; it submits PRs for human approval, supporting asynchronous collaboration and control.

What is the user experience like?

Interaction is through Fine’s web interface ("AI Palette"), chat, and integrations. You can ask questions in plain English about your codebase, such as understanding specific files or components, and get immediate, contextual responses powered by aggregated data from the knowledge graph.

What are the use cases for Fine?

Fine is optimized for AI and LLM applications, backend and REST API development, and incremental UX/UI improvements, helping small teams automate routine coding tasks and accelerate product innovation.

How does Fine differ from tools like GitHub Copilot?

Unlike autocomplete tools, Fine acts autonomously on tasks, working in its isolated environment and creating branches and PRs, integrating deep codebase context, and managing entire coding tasks asynchronously rather than assisting interactively or inline.
