In their own words
SiYuan
SiYuan is a personal knowledge management system for building a linked collection of notes. It supports Markdown, block-level references and bidirectional links, and organizes content into blocks with more than 20 block-level and more than 10 span-level element types. Backlinks can be filtered and searched; relationship graphs are available across a notebook and at block level. Databases support relations, rollups and templates, while flashcards use the FSRS spaced-repetition algorithm. Its AI feature connects to OpenAI for writing continuation, translation, summaries, brainstorming and grammar or spelling corrections. SiYuan supports offline access, and the maker describes multi-device synchronization as incremental and end-to-end encrypted. It is available on Windows, macOS, Linux, iOS, Android and the web, with a Chrome/Edge extension, API and Docker self-hosting. The maker says data stays under the user's control on their device. Free access is free; PRO Features is listed at $64 a month with lifetime-use wording, and Subscription at $148 a month with 8GB cloud storage.
Supernotes
Supernotes is a note-taking app that organizes ideas, records, tasks, and lists as digital notecards. Cards can include equations, tables, images, checklists, and emojis, with a soft limit of 1,200 characters. Users can tag, nest, and link cards, search them, and explore their connections with graph views. The apps work offline and merge changes and sync when a device reconnects. Cards can be shared for read-only access or collaborative editing in real time. Supernotes imports from Obsidian, Roam Research, Google Keep, Notion, or Markdown, and exports notes as PDF, JSON, or Markdown. It offers an API and lists integrations including Telegram, Raycast, Pipedream, email, SupaSend, and Funnel. The company says notes are encrypted in transit with SSL and at rest with AES-256, and staff do not access note content without express permission during support. The free Starter plan lists 100 cards. Unlimited costs £6 a month, billed as £72 billed annually, and includes unlimited cards, AI Superpowers, full API and integrations, and priority support.
