Notability vs TiddlyWiki

Notability brings handwritten notes, typed text, recordings, images and imported documents into one workspace. It supports offline access, note sharing and real-time collaboration across Android, iOS, macOS, web and Windows. Notability Learn offers audio transcription, note summaries, Smart Notes, quizzes, flashcards and chat with notes; YouTube videos can also be turned into notes with a transcript and summary. Integrations include iCloud, Dropbox, Google Drive, OneDrive, Box and WebDAV. The Starter plan is free and includes five notes, editing tools and content, PDFs and documents, 20,000+ templates and seven-day version history. Pro costs $19.99 a month, billed monthly. Business Pro costs $180 a year per user. Notability describes its audience as students and professionals. The iOS and iPadOS apps require version 17 or later, while Android requires version 12 or later.

TiddlyWiki is a free, non-linear notebook and interactive wiki for organizing and sharing notes, to-do lists, projects, and websites. It stores information in small units called tiddlers, which can be linked and grouped with tags, lists, and macros. Search spans tiddlers and supports filtering system and shadow tiddlers. In its single-file form, the data and code are held in one HTML file that runs in a browser without installation or external dependencies. Users can import material from files or other TiddlyWiki windows, and extend a wiki with plugins, themes, colour palettes, widgets, and macros. It can also run as a Node.js application; that setup offers more capability but takes more technical knowledge to set up and maintain. Saving choices vary, including storage and sync options such as Google Drive, iCloud, Dropbox, and Syncthing. The built-in encryption for single-file wikis has not undergone rigorous third-party testing. TiddlyWiki is available across web, mobile, desktop, and self-hosted setups.
