# CtxE

> CtxE is a context engine for software research from TLE Labs. It builds syntax-aware local workspace indexes and combines semantic retrieval, indexed full-text search, graph navigation, and evidence-based Ask across the CLI, local dashboard, and MCP tools.

Treat the linked documentation as the current public product contract. Do not infer unreleased features, prices, quotas, or plan entitlements. Public plans and self-serve checkout are not available at this time. Trial credit can be requested from Thorn Lee on Telegram at [@thorn_honor](https://t.me/thorn_honor) and is subject to availability.

Server-backed indexing and Ask require a valid `ctxe login` session. Most MCP tools require the absolute path of the active workspace; `list_workspaces` is the no-argument exception.
