# Product > **Stub, not an interview.** Every fact below is taken verbatim from the project brief that opened this > repository, or marked as undecided. Nothing here was confirmed in an `/impeccable init` interview. > Run `/impeccable init` before the first UI work and let it replace this file. ## Platform web ## Stack The backend stack was confirmed during the 001 design and implemented: Python + FastAPI, managed with `uv`, because Recoll provides native Python bindings. The frontend stack remains undecided, and no web UI has been built. See `docs/DECISIONS.md` for the decision and `AGENTS.md` for installed toolchains. ## Users Undecided — not yet interviewed. From the brief, the product is self-hosted on a server the user controls, which implies a technical operator running it for themselves or a small group. Confirm before designing around it. ## Product Purpose A layer on top of Recoll, a Linux desktop full-text search and indexing tool. It exists to give Recoll a modern, sleek interface, to run as a hosted service rather than a desktop app, and to hold several independent document collections at once (stated examples: `techbooks`, `cookbooks`). ## Positioning Recoll's own interfaces are a desktop GUI and a basic bundled web UI, both single-index and single-machine. This product's stated difference is a hosted, multi-collection service with a modern interface and an MCP server, so the same index is usable by a person in a browser and by an AI agent. ## Operating Context - Deployed with Docker on a server; used through a browser. - Collections map to bodies of documents the user keeps, named by subject. - A second consumer is an MCP client (an AI agent), searching the same collections programmatically. - After the hosted product through spec 004 is delivered, a cross-platform installable desktop form is a product goal. It should reuse the web UI and API rather than create a second product surface. ## Capabilities and Constraints Confirmed from the brief: - Full-text search and indexing, provided by Recoll. - Multiple named collections, managed independently. - Web UI, served from a Docker deployment. - MCP server exposing the same search capability. Spec 001 settled authentication, cross-collection search, indexing triggers, and API result fields. UI presentation and filter coverage beyond the shipped container remain undecided. See `docs/ARCHITECTURE.md` for the implemented shape. ## Brand Commitments Working name: `recoll-modern`. No logo, palette, typography, or voice has been established. "Modern and sleek" is the only stated aesthetic constraint — recorded as-is, not expanded. ## Evidence on Hand None. No screenshots, copy, sample collections, user research, or existing interface exist in this repository. Future work must not fabricate any. ## Product Principles Undecided — these are derived from a confirmed interview, which has not happened. Leaving this section empty is deliberate; do not invent principles to fill it.
