Modern documents increasingly contain diverse multimodal content — text, images, tables, equations, charts, and multimedia — that traditional text-focused RAG systems cannot effectively process. RAG-Anything addresses this challenge as a comprehensive All-in-One Multimodal Document Processing RAG system built on LightRAG.
- 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!

DB-GPT
AI Native Data App Development framework with AWEL(Agentic Workflow Expression Language) and Agents
Project mention: Launch HN: Gecko Security (YC F24) – AI That Finds Vulnerabilities in Code | news.ycombinator.com | 2025-08-01Yes, that's exactly what we do. Some examples: https://github.com/eosphoros-ai/DB-GPT/pull/2650, https://github.com/dagster-io/dagster/pull/30002
We just need to follow responsible disclosure first by notifying the maintainers, working with them on a fix, and making it public once it is resolved.

- Project mention: Launch HN: Onyx (YC W24) – The open-source chat UI | news.ycombinator.com | 2025-11-25
> ease of installation, streaming support, model agnosticity, chat persistence and blob support
we have all of those!
> how onyx is comparable
For an AI-powered research assistant, Onyx might just work out of the box. We have ~45 connectors to common apps (https://github.com/onyx-dot-app/onyx/blob/main/backend/onyx/...), integrations with the most popular web search providers (https://github.com/onyx-dot-app/onyx/blob/main/backend/onyx/...), and a built in tool calling loop w/ deep research support (https://github.com/onyx-dot-app/onyx/blob/main/backend/onyx/...). If you wanted to customize, you could pretty easily tweak this / add additional tools (or even rip this out completely and build your own agent loop).
