Autocomplete suggests the next line while you type. Crayon takes a whole task — reads the relevant code, writes a plan, runs commands, edits files, and fixes failing tests on its own, showing you each step along the way.
Instead of stuffing your entire repository into the prompt, Crayon indexes the codebase with tree-sitter and a local SQLite graph, then loads only the files, symbols, and imports a task needs. Lower cost, fewer hallucinations.
You choose the permission mode — Ask, Auto-Edit, or Auto. Edits are applied as reviewable diffs (with per-hunk approval), and there are built-in guards against path traversal, oversized reads, destructive commands, and SSRF on outbound fetches.
Anthropic, OpenAI, Google, and OpenRouter with your own key, or a local Ollama server for fully offline, zero-cost runs. You can hot-swap models mid-conversation.
