OutlineMySource (v0.1.1)

Extract a Markdown outline from the current webpage before you read it deeply (Readability-first, no uploads).

OutlineMySource builds a structured Markdown outline from content you already have—so you can scan the shape of an article, PDF, pasted notes, subtitles, or a local audio/video file before investing deep reading or editing time. How it works • Active tab (websites): Readability-style extraction when the page has a clear article, then a visible-text fallback. Processing runs in your browser on your device. • Chrome built-in AI (when available): On supported Chrome versions, the extension can use Chrome’s on-device Summarizer API (Gemini Nano) to produce a concise synthesized outline from web pages and pasted text. If the API is unavailable or not ready, it automatically falls back to an extractive outline (quoted snippets from the source). • Local files: Open PDFs, UTF-8 text, subtitles (.srt / .vtt), or audio/video from disk. Files are not uploaded to our servers. PDF parsing, speech recognition (Whisper via Transformers.js / ONNX), and optional semantic indexing run locally in Chrome. • Audio & video: Local transcription with progress and cancel. Long jobs use a background worker so the panel stays responsive. When Chrome’s Summarizer is available and transcription quality is good, the main outline may use on-device synthesis on the transcript; otherwise you get an extractive outline with clear metadata in the export. • Outline format: Markdown with a compact YAML metadata block (platform, engine used, fallbacks)—easy to save, diff, or paste into notes and AI tools. Why install it • Skim-first workflow: See headings and spaced excerpts (or a short synthesis when Chrome AI is on) instead of drowning in full pages or long transcripts. • Privacy-minded: No account required. Core processing stays on your machine. Network may be used only when first loading optional ML assets (e.g. speech models from public CDNs) into the browser cache—similar to other local-ML extensions. Summarizer mode uses Chrome’s built-in on-device model, not AI4Context servers. • Export: Download the outline as .md with one click. Languages Panel UI in English and Spanish (language selector in the extension). Good to know • Outlines are meant to help you skim and orient—not to replace careful reading, legal review, or professional transcription. • Chrome’s Summarizer requires a compatible Chrome channel and user gesture; availability varies by device and Chrome version. • Long captures may be clipped to a generous character limit noted in the export metadata. • The Microsoft Edge listing is a separate build without Chrome’s Summarizer; it uses extractive outlines plus the same local Whisper/MiniLM media path.
