What it does

inktomd converts files and URLs to clean Markdown for ChatGPT and Claude. Raw documents waste tokens on formatting noise — inktomd strips it out, using up to 82% fewer tokens for the formats that benefit most. Supports 28 formats: PDF, Word, Excel, PowerPoint, Jupyter notebooks, YouTube transcripts, ArXiv papers, Notion exports, and more. Also ships a free API and MCP server for Claude Code and Cursor. Free, no signup, files never stored.

Free online converter: PDF, Word, Excel, PowerPoint, EPUB, CSV, JSON, ZIP, YouTube to Markdown. Prepare your documents for ChatGPT and Claude instantly.

Convert any file to clean Markdown before sharing with AI — using up to 82% fewer tokens. No account required. Files are processed in memory and deleted immediately. Clean Markdown strips the bloat raw files carry — so your prompts cost less and the model spends its attention on what actually matters. Pick a format for a focused converter, or just drop anything into the box above. ChatGPT and Claude were trained on Markdown. When you paste a raw PDF or Word doc, the model wastes processing power — and your tokens — parsing formatting that means nothing to it. inktomd converts your file to the format AI actually understands. Cleaner input, better output, lower cost. See our PDF converter…from inktomd.com

  I made a tool to clean and convert any webpage to Markdown2024 · markdowndown.vercel.app · ▲441

  My partner usually writes substack posts which I then mirror to our website’s blog section. To automate this, I made a simple tool to scrape the post and clean it so that I can drop it to our blog easily. This might be useful to others as well. Oh and ofcourse you can instruct GPT to make any final edits :D

  Markdown Converter 2025 · markdownconverters.com · ▲12

  Hey HN I built MarkdownConverters.com — a tool that converts any file format (PDF, DOCX, PPTX, HTML, or URL) into clean, structured Markdown. I often needed to prep documents, reports, or scraped pages for AI pipelines, documentation, or version control, but existing tools either broke formatting, lost code blocks, or produced unreadable Markdown. So I built something that focuses on: • Accurate structure (headings, lists, tables, code, links) • Consistent Markdown output ready for LLMs or docs • Fast, browser-based conversion with privacy-friendly processing • Support for multi-format and…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
