microsoft/markitdown

Python tool for converting files and office documents to Markdown.

Microsoft Just Solved Document Ingestion for AI Devs (MarkItDown)

Market Signal

Why It Has Market Pull

Microsoft's markitdown has become a de facto standard for converting files into LLM-ready Markdown — now near 180,000 GitHub stars and 13,250 forks, still shipping same-day commits nearly two years after a front-page Hacker News debut; real-world testing shows it excels at Office documents but still struggles with complex PDF tables.

  • ~180,000 GitHub stars, 13,250 forks, 624 open issues, commits pushed the same day as this check
  • Hit Hacker News front page within days of release (329 points, 81 comments) and gained ~25,000 stars in its first two weeks
  • Handles Office docs, images (with EXIF/description), audio transcription, HTML, CSV/JSON/XML and ZIP archives in four lines of code
  • A companion MCP server shipped in spring 2025, extending it directly into agent tool-calling workflows
  • Multiple open GitHub issues document that PDF table/heading structure is frequently lost since the default backend does text-only extraction

TERMy – A fast terminal assistant that does not use LLMs

216 pts

I love research and development, you may have heard of me because of PJON (Padded Jittering Operative Network). It is a network protocol I started developing in 2010, which was recently implemented in silicon by the ETH Zurich university thanks to the research of Pius Sieber. I am excited to share with you TERMy, a terminal assistant built on top of the NPC-Forge framework. Unlike everything else being built today, TERMy does not use embeddings, machine-learning or LLMs. It runs on the CPU (even... (216 points, 45 comments).

Aura – a Rust agent that investigates and fixes production incidents

27 pts

We run a SaaS that handles petabytes of data. Our SRE team experimented with using claude, openclaw, langchain, etc. within our incident response workflows. We struggled with overflowing context, lethal trifecta vectors, hallucinations, and burned a lot of frontier tokens mostly on easy work. Approval fatigue was a challenge, and we drew a hard line at relaxing permissions in production. Long story short, we built and open-sourced AURA, a Rust-based harness specifically designed for the type of... (27 points, 6 comments).

VODForge – a free local desktop UI for YouTube video/playlist downloads

I built VODForge because I work with a CTV company that needed to pull YouTube videos from our channel partners into our media workflow. Converter sites are always an option but the bitrate wasn't optimal for a CTV network that needs to make multiple streaming version off of a single source file. So I build vodforge to use yt-dlp and ffmpeg under the hood with preconfigured settings for the highest quality end result, automatically adjusting the output settings based on source quality, frame rat...

I’m Nate, the founder of Ardent. We just shipped our public beta, and we’d love your thoughts! Ardent is an agent running in a desktop (Electron) app built to help with knowledge work, designed for less-technical people outside engineering. Think Codex or Claude Cowork, but built around collaboration and customization. I know, I know, it’s yet another agent harness! Ardent is a little different – it leans heavily on codegen to solve problems. Most agents are basically just a bag of tools and a w... (10 points, 2 comments).

Video generation with a synchronized soundtrack MiniMax-H3 — unquantized, split across two Spaces Joint video and soundtrack out of a single denoising pass, at bfloat16 with no quantization anywhere. This Space is the denoising half: the 61.73 GiB transformer and the two autoencoders. The 62.14 GiB Qwen3-VL conditioner runs in qwen3vl-conditioner, which this Space calls over the gradio API for every request. The weights are the public MiniMaxAI/MiniMax-H3 diffusers checkpoint. MiniMax-H3 is 195.9 GiB in bfloat16 and a ZeroGPU Space is evicted at 150 GB of storage. An unquantized single Space is therefore impossible, which is why quantized demos of it run NVFP4 or float8 weights. Cut the Mini...
