Injects a browser extension overlay into web pages and YouTube video players that enables users to select and highlight text/sections with customizable colors. The extension uses DOM mutation observers to track page changes and maintains highlight state in the browser's local storage, syncing selections across page reloads. Highlights are stored with metadata including URL, timestamp, and color tag for later retrieval and organization.
Unique: Extends highlighting to YouTube videos in addition to web articles, using timeline-based selection rather than transcript parsing, and stores all highlight metadata locally with color-coding taxonomy for multi-source organization
vs alternatives: More lightweight than Notion Web Clipper for quick highlighting workflows, and covers video content where Pocket and Instapaper focus only on articles
Provides a personal dashboard interface that aggregates all highlights across sources into a searchable, filterable library. Uses a tag-based taxonomy system and color-coded categorization to organize highlights by topic, source, or custom metadata. The library supports full-text search across highlight content and source URLs, with sorting by date, source, or color tag. Highlights can be grouped into custom collections or folders for thematic organization.
Unique: Combines color-coded visual taxonomy with tag-based organization and full-text search in a unified dashboard, allowing users to organize highlights by multiple dimensions simultaneously without requiring manual folder hierarchies
vs alternatives: More intuitive visual organization than Evernote's tag-only system, and faster to navigate than Notion's database-based approach for quick highlight retrieval
Processes selected highlights or entire collections through an LLM API (likely OpenAI or similar) to generate concise summaries, key takeaways, or thematic synthesis. The extension batches highlights by source or collection and sends them to the backend with context about the original article/video, receiving structured summaries that are cached and displayed in the library. Summaries are regenerable and can be customized by summary type (bullet points, paragraph, key quotes).
Unique: Applies LLM summarization specifically to user-curated highlight collections rather than full articles, preserving user intent through highlight selection while generating synthesis across multiple sources
vs alternatives: More targeted than article-level summarization tools like Summify, since it works on user-selected content; more flexible than static note-taking summaries since regenerable on demand
Enables users to publish highlights and collections to a public or semi-public community feed where other Glasp users can discover, upvote, and follow curators. The backend maintains a social graph of follower relationships and uses engagement signals (upvotes, saves, shares) to rank highlights in discovery feeds. Users can browse highlights by topic, trending curators, or follow specific users to see their new highlights. Shared highlights include attribution to the original curator and link back to the source article/video.
Unique: Builds a social graph around highlight curation rather than full articles or notes, allowing users to follow curators and discover highlights through peer networks and engagement signals rather than algorithmic recommendations alone
vs alternatives: More focused on curation than Twitter's general sharing, and more community-driven than Pocket's algorithmic recommendations
Exports highlights from the Glasp library to external tools and formats including CSV, JSON, Markdown, and direct integrations with Notion, Obsidian, and other note-taking apps. The export pipeline preserves metadata (source URL, timestamp, color tag, collection) and formats highlights according to the target tool's expected structure. For native integrations (Notion, Obsidian), the extension uses their respective APIs to create new pages or notes with highlights automatically organized by collection or source.
Unique: Provides bidirectional integration with popular knowledge management tools (Notion, Obsidian) via their native APIs, preserving metadata and enabling highlights to be incorporated into existing personal knowledge graphs rather than siloed in Glasp
vs alternatives: More integrated with modern PKM tools than Pocket or Instapaper, which offer only basic export; more flexible than Notion Web Clipper since it works with any source and multiple export targets
Detects the type of content being highlighted (article, YouTube video, academic paper, blog post) and extracts relevant metadata including title, author, publication date, video duration, and thumbnail images. For YouTube videos, the extension captures the video ID and timestamp of highlighted sections, enabling users to jump directly to relevant moments. For articles, it extracts the article text, byline, and publication metadata. This metadata is stored alongside highlights to provide rich context in the library.
Unique: Automatically extracts and preserves rich metadata (author, publication date, video timestamps) from diverse content types, enabling highlights to be treated as citable sources rather than orphaned text snippets
vs alternatives: More comprehensive than Pocket's basic URL storage, and captures video-specific metadata (timestamps) that other highlighters ignore
Stores not just the highlighted text but also surrounding context (previous and following sentences/paragraphs) from the original source, enabling users to understand the highlight's meaning without revisiting the source. When viewing a highlight in the library, users can expand to see the full context window. The extension uses DOM traversal to capture paragraph-level context at highlight time and stores it alongside the highlight text. Context is searchable and can be included in exports.
Unique: Automatically captures and stores surrounding context at highlight time, enabling offline understanding of highlights without requiring the original source to remain accessible or the user to revisit it
vs alternatives: More context-aware than simple text highlighters like Liner, which store only the selected text; more practical than full-page clipping tools like Notion Web Clipper for quick reference
Renders a hierarchical tree view of the active Vue application's component structure, allowing developers to click through nested components and inspect their props, data, computed properties, and methods in real-time. The extension hooks into Vue's internal component registry via a bridge script injected into the page, enabling live traversal without requiring source map access or code instrumentation beyond Vue's built-in reactivity system.
Unique: Uses Vue's internal component registry and reactivity system to provide live tree traversal without requiring source maps or AST parsing, enabling instant inspection of dynamically rendered components that don't exist in source code
vs alternatives: Faster and more accurate than DOM inspector alone because it shows logical Vue component structure rather than rendered HTML, and doesn't require manual prop tracing through code
Captures and displays the reactive state (data, computed properties, watchers) of selected components in real-time, with change history tracking that shows which properties mutated and when. The extension intercepts Vue's reactivity proxy layer to log state mutations as they occur, enabling developers to correlate UI changes with state changes without console.log debugging.
Unique: Integrates directly with Vue's reactivity proxy layer (Proxy in Vue 3, Object.defineProperty in Vue 2) to capture mutations at the source rather than polling or diffing, providing zero-latency change detection
vs alternatives: More accurate than Redux DevTools for Vue because it tracks Vue's native reactivity system rather than requiring explicit action dispatching, and works with both Vuex and Pinia without separate configuration
Displays component prop definitions (type, required, default value) and validates runtime prop values against their definitions, highlighting type mismatches or missing required props. The extension inspects component prop definitions from the component's props object and compares runtime values against expected types, displaying validation errors in the DevTools panel.
Vue.js DevTools scores higher at 41/100 vs Glasp at 37/100.

Unique: Validates runtime prop values against component prop definitions in real-time, providing instant feedback on type mismatches and missing required props without requiring additional validation libraries
vs alternatives: More integrated than PropTypes or TypeScript because it validates at runtime using Vue's native prop system, and provides visual feedback in DevTools without requiring console warnings
Provides a dedicated inspector for Vuex store state with mutation history replay, allowing developers to step backward and forward through state mutations and inspect the store at any point in time. The extension subscribes to Vuex's mutation stream and maintains an immutable history of state snapshots, enabling time-travel debugging by replaying mutations in sequence.
Unique: Maintains an immutable snapshot history of store state by subscribing to Vuex's mutation stream and replaying mutations sequentially, enabling true time-travel without requiring explicit action logging or middleware configuration
vs alternatives: More integrated than Redux DevTools for Vue because it's built specifically for Vuex's mutation model and doesn't require additional middleware setup, and provides instant access to store state without serialization overhead
Provides a dedicated inspector for Pinia store state with real-time mutation tracking and replay capability, designed for Vue 3's modern state management. The extension hooks into Pinia's subscription API to track state changes and actions, displaying store state with full mutation history and the ability to step through state changes chronologically.
Unique: Leverages Pinia's built-in subscription API and action tracking to provide native integration without requiring middleware or wrapper code, enabling automatic tracking of all store mutations and actions with zero configuration
vs alternatives: More lightweight than Vuex DevTools because Pinia's simpler architecture requires less overhead, and provides better action tracking than Vuex because Pinia explicitly separates actions from mutations
Displays the Vue Router route configuration as a tree or graph, showing all defined routes, their parameters, and navigation history. The extension subscribes to Vue Router's navigation guards and history stack, displaying the current route, route parameters, query strings, and a chronological log of all route transitions with their triggers and timing.
Unique: Subscribes to Vue Router's navigation hooks and history stack to provide real-time route tracking without requiring manual instrumentation, and displays both static route configuration and dynamic navigation history in a unified view
vs alternatives: More integrated than browser history inspection because it shows logical Vue routes rather than raw URLs, and provides route parameter and query string parsing without requiring manual URL parsing
Records component render times, lifecycle hook execution duration, and event handler performance during application runtime, displaying results in a timeline view with flame graphs and performance metrics. The extension uses Vue's performance hooks (or browser Performance API) to measure component initialization, update, and unmount phases, correlating performance data with component names and user interactions.
Unique: Integrates with Vue's lifecycle hooks to measure render performance at the component level rather than relying on generic browser profiling, enabling precise identification of slow components without requiring manual instrumentation
vs alternatives: More granular than Chrome DevTools Performance tab because it shows Vue component-level metrics rather than generic JavaScript execution time, and correlates performance data with component names and lifecycle phases
Captures all custom events emitted by components and displays them in a chronological log with event names, payloads, and source/target components. The extension subscribes to Vue's event system and records each emit with timestamp and context, allowing developers to replay events in sequence or jump to a specific point in the event timeline to inspect application state at that moment.
Unique: Maintains a temporal event log with application state snapshots at each event, enabling developers to jump to any point in the event timeline and inspect the complete application state at that moment without manual state reconstruction
vs alternatives: More useful than console.log event tracking because it provides a structured, searchable event history with automatic state snapshots, and enables temporal navigation without requiring manual breakpoint setup
