Uses AI to send me daily Slack summaries

What it does

I built a small open-source tool to deal with my own content overload. It monitors newsletters, blogs, and RSS feeds, extracts new posts, summarizes them using LLMs (OpenAI or local Ollama), and sends one Slack digest each morning. Everything runs in a single Docker container using Node.js+SQLite. • RSS, HTML, or LLM extraction • Summaries via OpenAI or local models • Simple web UI to review items, mark read, flag, delete • Slack webhook integration • Fully self-hosted, no external dependencies

    The official Slack AI product looks great, but with limited access and add-on pricing, I decided to open-source the version I built. Especially for all the communities on Slack that would have to convert to paid and buy the upgrade to access the official SlackAI product/add-on which is not going to be financially viable in most cases. There's no plan to sell anything, just something I built as a way to learn some new tools that I thought others might get use out of. The repo is a ready-to-run slack app that provides thread summaries and channel overviews on demand using OpenAI (heavy…
