HoverNotes
HoverNotes is a Chrome extension that transforms video tutorials from platforms like YouTube, Udemy, Coursera, and Bilibili into distraction-free, AI-generated Markdown notes stored directly in your Obsidian (or any local) vault. It watches the video in real time, capturing key concepts, code snippets, equations, diagrams, and timestamped screenshots, surpassing transcript-only tools by understanding visual content. It presents a split-view learning environment, removing ads and recommendations while letting users edit notes as they generate, ensuring improved retention and accuracy. With full local-first storage and Obsidian integration, it gives users complete control over their knowledge. The free plan includes basic features with 20 minutes of AI processing, while paid tiers unlock hours of AI note-taking, advanced summaries, priority support, and unlimited use.

Gravity
Gravity is a personal note-taking app for capturing and reviewing short thoughts on iPhone, iPad, Mac, and Android. It stores notes in one chronological stream, with the newest at the top; older notes move down as new ones are added, and users can bring useful notes back to the top. Notes support search, Markdown, checklists, tags entered as text prefixes, archiving, and export to JSON or Markdown. The apps work offline and store notes locally; iPhone, iPad, and Mac versions can optionally sync through the user’s iCloud account. A companion macOS command-line tool can search, add, edit, archive, import, and export notes, including for scripts and AI agents. Gravity is designed for individual note capture and review rather than shared team workspaces or structured project knowledge bases.

TaskNote
TaskNote is a note-taking app with a kanban board and reminders, built for one person rather than a team. Notes have rich formatting (headings, checklists, tables, columns, images, highlights) and are stored as Markdown, so they open anywhere. Any note can be turned into a task or attached to a kanban card; reminders fire desktop notifications at the time you set. Full-text search, a command palette, version history, trash, split view with up to six notes side by side, and built-in templates (shopping list, daily plan, brain dump, meeting notes and more). Import from Evernote, Google Keep, Notion, Simplenote and Markdown; a Chrome extension clips web pages into notes. The Windows app keeps everything in a local file, runs without an account and works fully offline. The web version syncs with end-to-end encryption: the key never leaves your device and the server stores only ciphertext. Free plan with no time limit; a one-time Lifetime licence on Windows instead of a subscription.

writenode
writenode is a browser-based note-taking and personal knowledge tool for capturing and connecting information as users browse. Its Chrome extension lets users save selected text, webpages, links, PDFs, and spoken notes without leaving the current page. Captures become searchable, connected nodes, and a knowledge graph helps users see relationships among saved ideas. Users can ask questions grounded in their own materials and use a rich-text editor with AI actions to revise, summarize, expand, or reformat notes. A built-in Model Context Protocol (MCP) connector lets Claude read and write the user's writenode memory. The web app also supports custom mental models that shape AI responses. Researchers, builders, writers, and other knowledge workers can use writenode to collect web-based information and retrieve or develop it later. Users can bring their own AI and transcription provider keys.
