## Gizmo

Gizmo is built around a simple idea: studying should feel less like a chore and more like a game. You paste in your material — class notes, a PDF, a PowerPoint deck, a Quizlet set or a YouTube lecture — and the AI breaks it down into crisp question-and-answer flashcards. From there, Gizmo's spaced-repetition engine decides when each card should reappear, focusing your sessions on the items you keep getting wrong.

The product leans heavily on active recall: instead of re-reading, you answer, get instant feedback, and watch your mastery streaks build. A gamified interface, streaks, leaderboards and study 'live' sessions are designed to keep students coming back daily, which is why it has spread quickly among GCSE, A-level and university students.

Gizmo works across web, iOS and Android, and supports importing from YouTube links, PDFs, PowerPoint files and pasted notes. A generous free tier covers the core flashcard and quiz workflow, and the team also publishes study guides and blog content around exam prep.

**Pricing & Plans:** Free to use for the core flashcard, quiz and spaced-repetition workflow. Premium features are offered through subscription options presented in-app; check the app for current tiers.

- **AI flashcard generation:** Turn notes, PDFs, PowerPoint slides and YouTube videos into ready-to-quiz flashcards without writing cards by hand.
- **Spaced repetition engine:** Automatic scheduling resurfaces cards right before you would forget them, so review time goes where it is needed.
- **Active recall quizzes:** Answer-first quizzing with instant feedback instead of passive re-reading, reinforcing long-term retention.
- **Gamified study streaks:** Streaks, points and social study sessions keep motivation high and make daily review a habit.
- **Cross-platform access:** Study on the web, iOS or Android with your decks and progress synced across devices.

**Strengths:** Fast conversion of messy notes and PDFs into usable flashcards; Spaced repetition plus active recall is a proven learning combination; Free tier covers the core study loop; Works well on mobile for on-the-go review

**Limitations:** AI-generated cards occasionally need manual editing for accuracy; Some motivational features may feel gamified for adult learners; Best results require you to review consistently

## Models.dev

Models.dev exists to answer a very practical developer question: which model should I use, and what will it cost? The site organises every entry under a canonical identifier in the form provider/model, so the same model served by several providers can be compared directly rather than guessed at. Columns cover context window, maximum output, whether input and output are supported, reasoning, tool calling, structured output, temperature control, open versus closed weights, price per million tokens, and release and update dates.

Because model releases move fast, the catalogue is built to stay current, with sortable and searchable tables that let you scan by lab or provider and filter down to what matters. Entries include both closed flagship models and open-weight alternatives, making it useful for cost planning as well as capability research.

The project is open source and free to use, and it is intended to be consumed programmatically. Developers can pull the catalogue into their own tooling through a JSON API or a type-safe SDK, which makes it a practical backend for dashboards, routing logic, or internal cost calculators rather than just a reference page to browse.

**Pricing & Plans:** Models.dev is free and open source. It is a reference database, so the prices it lists are the per-million-token rates charged by the model providers themselves, not a fee for using the site.

- **Canonical model identifiers:** Every model uses a consistent provider/model format so the same model across providers can be compared directly.
- **Specification comparison:** Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
- **Pricing transparency:** Input and output prices per million tokens listed alongside release and update dates.
- **Open and closed models:** Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
- **Developer access:** Consume the catalogue through a JSON API or a type-safe SDK for your own tools and dashboards.

**Strengths:** Free and open source with no account required; Consistent canonical identifiers make cross-provider comparison reliable; Covers pricing, limits, and capabilities in one sortable table; Available as a JSON API and type-safe SDK for programmatic use

**Limitations:** It is a reference catalogue, not an inference or hosting service; Data quality depends on community and maintainer updates keeping pace with releases; Interface is aimed at developers and offers little guidance for non-technical users
