Summarize
Link in, signal out. Extract clean text and produce summaries from anything.
Summarize extracts clean text and produces summaries from web pages, files, YouTube videos, podcasts, and other audio or video. Use it from the Node.js CLI or from the Chrome Side Panel and Firefox Sidebar. Readability extraction with optional Markdown and Firecrawl fallbacks for web pages. File-aware extraction for PDFs, images, and text files. YouTube and podcasts: published transcripts first, then configured transcription fallbacks. Audio and video: local or cloud transcription with optional speaker labels. Video slides: scene-based frames, optional OCR, and timestamped output. SSE streaming render, sandboxed iframe preview. Works with configured API providers, OpenAI-compatible endpoints, Ollama, OpenRouter free models, and authenticated coding CLIs (Codex, Claude, Gemini, OpenClaw, GitHub Copilot).
Key Features

- File extraction: PDFs, images, and text files with file-aware extraction and model attachments
- YouTube and podcasts: published transcripts first, then configured transcription fallbacks (ffmpeg, yt-dlp, tesseract)
- Audio and video: local or cloud transcription with optional speaker labels
- Video slides: scene-based frames, optional OCR, and timestamped output
- Three modes: --extract (clean content only), --json (stable automation envelope), --slides (video frames)
- Chrome Side Panel extension: summarize active tab, chat with content, work with video transcripts and slides
- Firefox Sidebar support with optional daemon for CLI model backends, native media tools, OCR, shared caches
- Multi-provider support: API providers, OpenAI-compatible endpoints, Ollama, OpenRouter free models
- Authenticated coding CLIs: Codex, Claude, Gemini, OpenClaw, GitHub Copilot — reuses existing login sessions
- Bundled WebAssembly FFmpeg for common media without native install
- Library mode: @steipete/summarize-core for programmatic extraction without CLI dependency
- SSE streaming render — watch the AI draw the summary line by line

HTML Anything
The agentic HTML editor — Markdown is the draft, HTML is what humans read
An agent-era HTML editor from the team behind Open Design (40k stars). Turns any input (Markdown / CSV / Excel / JSON / SQL / raw notes) into ship-ready single-file HTML via your local AI agent. Auto-detects 9 coding-agent CLIs (Claude Code, Cursor Agent, Codex, Gemini CLI, GitHub Copilot CLI, OpenCode, Qwen Coder, Aider, IBM Bob), zero API key — reuses your existing logged-in session. 75 composable skill templates across 9 deliverable surfaces (magazine articles, keynote decks, resumes, posters, Xiaohongshu cards, tweet cards, web prototypes, data reports, Hyperframes videos). One-click export to WeChat / X / Zhihu, or download .html / .png. SSE streaming render, sandboxed iframe preview, format auto-detect.
BrowserAct
A real browser for AI agents. Break through anti-bot walls. Run parallel tasks. Human handoff when stuck.
BrowserAct enables AI agents and teams to perform real-browser automation, web data extraction, and account-based workflows. It helps agents get past anti-bot walls, hand off to humans across platforms when stuck, run parallel tasks without cross-contamination, and isolate multiple accounts in independent browsers — backed by stealth fingerprints, TLS rotation, residential proxies, CAPTCHA solving, and stable fingerprint-proxy setups for authenticated sessions. Two usage modes: fully cloud-managed execution (describe the website, filters, and fields — BrowserAct builds and tests a reusable scraping Bot), or local browser control driven by your own agent workflow (load the BrowserAct Skill, discover browser state with get-skills, run automation commands directly). 30+ pre-built Skills in the Solutions Catalog covering Amazon, Google Maps, YouTube, Reddit, WeChat, Zhihu, and more.
