# Compresr

> Compresr is an LLM context-compression API: send long context plus the query you want answered, get back a shorter context that keeps the answer-bearing spans and drops the rest. Public model: latte_v1 (query-specific). Python SDK, TypeScript SDK, or hosted HTTP API.

Every page below links to its Markdown twin (`<path>.md`), the plain-text surface an LLM or answer engine should read. The human-readable pages live at the same path without the `.md` suffix.
