Self-hosted knowledge management for SMEs: a split-screen Markdown editor whose sections an LLM refines while you write, and RAG question answering over the documents that result. FastAPI + Postgres/pgvector on the back, SvelteKit on the front, everything OpenAI-compatible and self-hostable. Squashed into a single commit; the development history stays local.

"""Editing the shipped system prompts.
|
|
|
|
Every prompt has a code default; a row exists only where an admin changed one,
|
|
and resetting deletes that row rather than storing a copy of the default. The
|
|
UI labels the keys from its own messages, so nothing user-facing is worded here.
