Context Capture Saver

Capture useful context from websites, PDFs, and YouTube transcripts into local JSON, Markdown, and/or SQLite storage you control. Context Capture Saver is designed for research and AI workflows where you want structured, provenance-aware data instead of ad hoc copy/paste. Key Features - Capture article-focused page content, not raw HTML. - Save with notes, highlights, and queued highlight workflows. - YouTube transcript capture with transcript-only, timestamped-segments-only, or both. - Bubble menu support on YouTube selections, including transcript save actions. - PDF extraction with metadata and selection-aware capture support. - Local storage backends: `JSON` (default), `Markdown`, `SQLite`, and `JSON + SQLite` (write both). - JSON output is always written under `json/` inside the selected folder. - Optional structured JSON chunks (`content.chunks`) in addition to full `documentText`. - SQLite backend uses a graph-ready schema for analytics and AI agent workflows. - Automatic migration of legacy SQLite databases (`captures`-only schema) to the latest schema. - Pending highlights/notes panel now shows queued annotations on-page with delete controls before save. Capture Workflows Websites Use right-click menus, shortcuts, popup, or bubble actions: - Save content - Save content with note - Save content with highlight - Highlight - Highlight with note YouTube On supported YouTube video pages: - Save transcript - Save transcript with note - Selection bubble includes YouTube transcript actions Transcript storage modes: - plain transcript text - timestamped transcript segments - both PDFs - Extracts text + metadata - Supports capture and highlight actions - Browser PDF viewer behavior can still affect some selection UX Data Storage Overview JSON Mode - Default mode. - Writes one capture file per save. - All JSON files are written under `json/` in the selected folder. - Optional setting can include `content.chunks` for agent-ready chunked retrieval while keeping full text. Markdown Mode - Writes one `.md` file per capture with YAML frontmatter metadata. - Body contains the core document text (no structured chunks or timestamped segments). - Highlights and notes use footnote-style anchors (`[^hl-N]`) placed inline where the highlighted text appears, with a "Highlights & Notes" footer section. - Markdown files follow the same folder organization options as JSON (date/type grouping). - Markdown is a lossy format compared to JSON/SQLite -- optimized for human readability, not round-trip data interchange. SQLite Mode - Writes/updates a single `context-captures.sqlite` file in the selected folder. - Uses SQL.js (no external DB server). - Automatically upgrades legacy DBs in place. JSON + SQLite Mode - Writes both outputs in the same save operation. - If one backend fails and the other succeeds, successful output is preserved and surfaced. Privacy - Data is written only to your selected local folder. - No required remote backend. - No cloud dependency in capture flow.
