Project mention: Kotaemon-papers: an open-source web app to chat with your academic papers | news.ycombinator.com | 2025-01-05
Hi HN,
Our team at https://github.com/Cinnamon/kotaemon/ has been working on a public demo to showcase the new advanced citation features in our RAG (retrieval-augmented generation) application.
Weโre excited to share a web app that lets users explore top daily machine learning (ML) papers on Arxiv (via the HuggingFace API) and upload their own Arxiv papers to get LLM-assisted summaries, mind maps, and answers to questions based on the content.
Some notable features:
- Instant Summaries & Mind Maps: Generate concise summaries and visual mind maps for any Arxiv paper.
- Transparent Citations: Verify AI-generated answers with clear, evidence-backed citations. Citations are highlighted directly in the in-browser PDF viewer.
- Flexible Citation Options: Choose between highlights and inline citations. Plus, click on any sentence in the AI-generated response to see its supporting source from the original paper.
- Multi-Paper Analysis: Compare, contrast, and compose summaries from multiple papers simultaneously.
- Complex Question Solving: Use Chain-of-Thought (CoT) reasoning mode to break down and solve complex questions step-by-step.
- Customizable & Private Hosting: Easily self-host or customize your private app via HuggingFace Spaces. You can securely connect your LLM and upload your own document collections.
Weโd love to hear your thoughts, feedback, and recommendations as we continue improving this tool.
Check out the demo here and happy hacking!

Project mention: Show HN: RomM โ An open-source, self-hosted ROM manager and player | news.ycombinator.com | 2025-06-11
What fortunate timing! Our next release will including a new, local-only "API" that uses Launchbox's GamesDB (https://gamesdb.launchbox-app.com/) as the metadata source. The entire database is loaded into Redis and games are matched on exact file names, so no data is ever sent to any cloud providers.

One project from GitHub Trending that really caught my attention is LibreTranslate. Itโs an open-source web app used to translate between languages, similar to Google Translate, but powered by the Agros Translate library. I have a deep passion for learning languagesโboth spoken and programming languagesโso this project feels like the ideal opportunity to merge these interests. In fact, one of my long-term goals is to contribute to the preservation of endangered languages, and working on LibreTranslate seems like the perfect starting point for that.
