Youtube to Markdown

Skip the Video, Extract the Knowledge. Transform streaming content into storable knowledge as Markdown.

• 🎛️ Modular — choose from full extraction, summary only, transcript only, or comments only
• 🧹 Cleaned transcript — broken into chapters and paragraphs with topic headings
• 💬 Comment analysis — curates and cross-analyzes comments against the summary
• 📐 Adaptive formats — claim-bullets, themed-claims, step-list, or flat-bullets based on content type

IMAP Slim

Secure and lightweight IMAP email CLI/MCP. Reply as Drafts and send with your client. Delete restricted.

• 🪶 ~814 tokens as an MCP server, or ~41 as a skill until you run a command
• 📧 Read & search — list, read, and search IMAP folders
• ✍️ Write drafts — create appends one, replace supersedes one; markdown renders to HTML plus a plain-text alternative, or send plain text exactly as written
• ↩️ Replies — the client quotes the original, HTML and inline images included, the way Thunderbird does; the model writes only the new text. Point-by-point for plain text
• 🔐 Secure — credentials in OS keychain (or env variables for Docker/CI)
• 🏢 Multi-account — multiple account support with named switching

Same actions are available as a skill-backed CLI (imap-slim-cli), which loads nothing into a session until a command runs. Install either, or both.

The Backstory

How to extract YouTube transcripts as Markdown summaries to my Obsidian vault? I knew of yt-dlp, but I wanted something more that would clean, format, summarize, analyze etc. LocalLLM was one option but never got the time.. Finally as checking out Claude Code skills in wild I thought that maybe there would be something already Done for Me. Well there was not, only something to build upon.

Four months later I added MCP server for IMAP email access as well, as I wanted to have email reading and drafting capabilities in Claude Code in lightweight manner.

Not so long after that I was playing with playwrights etc. as an LLM occasionally needs eyes and hands on the web. Most existing browser automation solutions are fat (Puppeteer, Playwright, full MCP servers). I found pengelbrecht's chrome-debug-skill, a clean single-file legacy CDP client, that I then modernized for more recent Chrome CDP.
