diStudero vs Nibomo

diStudero is a web-based study aid that turns uploaded material into AI-generated learning resources. It accepts PDFs, DOCX and PPTX files, photos, plain text and links, including scanned notes, and can produce flashcards, quizzes, notes, podcasts and infographics. Its tools also include mock exams, games, mind maps, assistants, timers and progress statistics. Generated flashcards can be edited, extended, printed or shared; the FSRS algorithm uses card performance to schedule reviews. A Chrome extension can analyze selected webpage text, translate in 15 languages, write with AI and import Google Docs documents up to 50,000 characters. On iPhone and Android, it installs from a browser as a progressive web app. The free tier allows 5 folders, 5 MB of storage, one file per upload, 10 AI flashcards and 10 quiz questions per day, plus 10 chat messages per day. Pro Monthly is €11.99 a month and includes 20 credits per month; a 5-day trial is listed.

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.
