About Contextra

Contextra is a context engine for AI coding tools that reads your prompt's intent and injects only the relevant slices of your codebase. It builds a live structural map of your repo — files, exports, imports, types, and dependencies — without storing a single line of code. Instead of padding every prompt with manual context, it delivers exact file ranges like auth/middleware.ts:44–91, cutting token usage by up to 83% and producing dramatically more precise outputs. Developers, engineering teams, and anyone wiring AI agents into a real codebase benefit most. Contextra understands what you're actually asking, going beyond keywords to match your prompt's real goal against the semantic shape of your code. The result is a leaner context window, faster responses, and fixes that land in one shot — roughly 10× faster and 5× cheaper bug resolution, with zero manual overhead in your daily workflow. Standout use cases include debugging tangled auth flows, onboarding AI assistants to unfamiliar repositories, and feeding agents precise context before they burn tokens. Every feature circles one idea: your AI tools should already understand your codebase. By combining intent-aware parsing with surgical file-range injection, Contextra turns vague, expensive prompts into focused, high-signal requests that ship solutions in a single pass.
