Nibomo vs RemNote

Nibomo is a flashcard study app for web, iOS, and Android. Its FSRS spaced-repetition system schedules difficult cards sooner and familiar cards later, while AI can help create cards, improve their wording, and clarify answers. Studying on mobile works offline and syncs automatically. Users can import and export cards, tags, and related media, and AI agents can connect through MCP or the Agent API; the MCP server works with Claude, Cursor, or any MCP client. The hosted app is free during beta, with no credit card requirement, trial countdown, or plan-based quotas on cards, files, or total storage, though technical limits still apply. AI features and sync are included during beta, but higher AI usage may later require a provider API key or paid option. The open-source stack can be self-hosted on AWS, with infrastructure and third-party provider costs paid by the operator. Hosted sign-in uses a one-time email code rather than a password. Nibomo is built by Kirill Markin and operated by SAMO DANNI EOOD in Plovdiv, Bulgaria.

RemNote is a learning and note-taking app that turns notes, PDFs, and other sources into AI-generated flashcards, quizzes, and summaries. Its study tools include spaced repetition, practice quizzes, and card formats such as question-and-answer, fill-in-the-blank, lists, clusters, and image occlusion. Users can annotate PDFs and slides with highlights, drawings, and shapes, and source citations are available. Notes and flashcards remain accessible offline and sync when connectivity returns. RemNote offers desktop apps and mobile apps for iOS and Android. The free plan includes unlimited notes and flashcards and synced devices, plus 20 daily file uploads up to 8MB each and 250 monthly AI credits. It also limits free users to three annotated PDFs, five image occlusion cards, and one handwritten document. Pro is listed at $8 a month, and Pro with AI at $18 a month. RemNote was founded in 2020.
