Brainscape vs Nibomo

Brainscape is a flashcard study platform that uses AI to create cards and spaced repetition to organize review. Learners rate their confidence on a 1–5 scale, and the platform uses those ratings to adjust when cards return. AI can turn PDFs, documents, and presentations into flashcards. Cards can contain formatted text, images, sounds, and animated GIFs; users can invite students or instructors to contribute edits or feedback. Its library includes user-created and expert-certified cards across exams, languages, and professional certifications. Integrations support work with apps and tools, while the Ghost API can be used to create custom integrations. Brainscape is available on web, iOS, and Android. The individual Basic plan is free and includes 2,500 pre-loaded flashcards; the listed Pro (Individual) price is $7.99 a month, billed yearly. Enterprise group licensing has custom pricing. Brainscape says its AI features are opt-in and only raw study materials go to AI providers, which do not use Brainscape data to train their models. It also says it does not sell personal data or run personalized ads.

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.
