   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.

   We’re 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.

   We’d love to hear your thoughts, feedback, and recommendations as we continue improving this tool.

   Check out the demo here and happy hacking!

8. rasa

   7 19 20,941 3.6 Python

   💬 Open source machine learning framework to automate text- and voice-based conversations: NLU, dialogue management, connect to Slack, Facebook, and more - Create chatbots and voice assistants

   

   Project mention: Eliza Reanimated Published in IEEE Annals of the History of Computing | news.ycombinator.com | 2025-06-20

   Right before LLMs broke into the scene we had a few techniques I was aware of:

   * Personality Forge uses a rules-based scripting approach [0]. This is basically ELIZA extended to take advantage of modern processing power.

   * Rasa [1] used traditional NLP/NLU techniques and small-model ML to match intents and parse user requests. This is the same kind of tooling that Google/Alexa historically used, just without the voice layer and with more effort to keep the context in mind.

   Rasa is actually open source [2], so you can poke around the internals to see how it's implemented. It doesn't look like it's changed architecture substantially since the pre-LLM days. Rhasspy [3] (also open source) uses similar techniques but in the voice assistant space rather than as a full chatbot.
