What Gizmo does

Gizmo (legally operated as Save All Ltd, a UK private limited company headquartered in London) is a consumer-facing AI learning platform that converts unstructured study materials — notes, PDFs, YouTube videos, PowerPoint decks, and existing Quizlet sets — into AI-generated flashcards and quizzes. The platform layers generative AI and natural language processing over a spaced-repetition and active-recall engine, augmented by gamification mechanics (streaks, leaderboards, trophies) and a real-time multiplayer study feature called Gizmo Live. Distribution is exclusively digital and self-serve: users onboard via the gizmo.ai website or the iOS/Android mobile app without sales interaction, and payment is processed through Stripe, Apple Pay, or Google Wallet. The product is offered on a freemium model with monthly or annual premium subscriptions; pricing tiers are not publicly disclosed and are revealed at checkout.

The company's primary customer segments are secondary-school students preparing for standardized exams such as GCSEs, A-levels, and AP assessments, with a strategic growth focus on U.S. college and university students (the stated use-of-funds for the April 2026 Series A). Educators and self-learners are secondary personas. As of 2025, Gizmo reported more than 13 million users across 120+ countries, up from approximately 300,000 in 2023. The company employs roughly 7 people as of late 2025 / early 2026 and plans to scale to 30 employees using Series A proceeds, with concentration in engineering and AI roles. Gizmo raised a $3.5M seed round in September 2023 and a $22M Series A in April 2026 led by Shine Capital, with participation from Ada Ventures, Seek Investments, GSV, and NFX.

The business model is product-led growth with no enterprise or institutional channel: marketing is driven by SEO-optimized landing pages targeting high-intent study keywords, an organic blog (two posts reached #1 and #3 on Hacker News), user-generated social testimonials, paid retargeting via Meta and TikTok pixels, and earned media. Revenue mechanics are subscription-based with a free base tier; specific ARPU, conversion rates, and revenue figures are not publicly disclosed. The company holds no disclosed patents or trademarks and relies on its own and third-party machine learning models for core AI functionality.

Core offering

Gizmo is an AI-powered learning platform that converts study material (notes, PDFs, YouTube videos, PowerPoints, textbooks) into AI-generated flashcards and quizzes. It applies spaced repetition and active recall to help students memorize and retain information more efficiently, and includes a Flashcard Maker with gamification and a real-time multiplayer study mode (Gizmo Live). The product is delivered via web and iOS/Android apps and is used by 13M+ learners across 120+ countries.

Product overview

Gizmo (operated by SAVE ALL LTD) is a single unified AI-powered learning platform with a core app plus a suite of input-converter modules and one social extension, rather than a portfolio of unrelated products. The core platform is the Gizmo AI Learning App, which uses generative AI, natural language processing, and spaced repetition to turn user content into personalized flashcards and quizzes. Wrapping that core are input-specific modules — Flashcard Maker (the central creation tool), Notes to Flashcards, PDF Summarizer, PDF to Flashcards, YouTube Summarizer, YouTube to Flashcards, PowerPoint Summarizer, PowerPoint to Flashcards, and the Quizlet-to-Flashcards importer — each feeding the same AI generation pipeline. On top of that, Gizmo Live provides real-time multiplayer study sessions, and the Gizmo Mobile App delivers the entire experience on iOS and Android. Premium features are sold via monthly or annual Gizmo Subscriptions.

Direct peers

• Quizlet: The dominant flashcard and study platform with hundreds of millions of users and established Quizlet Plus subscription. Gizmo explicitly positions itself as a 'free alternative to Quizlet' and offers a Quizlet-to-Gizmo importer, making this a direct head-to-head competitor in the same product category.
• Knowt: AI-powered Quizlet alternative offering free AI-generated flashcards and study tools to students. Targets the same exam-prep and student use case with a similar freemium model and AI ingestion approach.
• Anki: Open-source spaced repetition flashcard application with a large user base among medical students, language learners, and power users. Anchors the SRS + active recall learning methodology that Gizmo also leverages.
• Quizizz: Gamified quiz and formative assessment platform used widely by K-12 and teachers. Overlaps Gizmo's quiz-generation and gamification mechanics, serving a similar student and educator audience.
• Brainscape: Commercial spaced-repetition flashcard platform with certified content and a paid subscription model. Closely mirrors Gizmo's core value proposition of combining SRS with curated/professional study content.
• StudySmarter: AI-driven study platform with flashcards, summaries, and spaced repetition targeting students across European exam systems. Closely comparable in AI ingestion + SRS + freemium mechanics.
• Memrise: Language-learning platform with gamified flashcards, streaks, and spaced repetition. Comparable consumer learning model with the same engagement-driving gamification layer Gizmo uses.

Broad incumbents

• Duolingo: Much larger consumer learning platform with proven gamification, streaks, and freemium-to-paid conversion mechanics. Not a direct study-tool competitor but a model for how to scale and monetize a gamified consumer learning product.
• Khan Academy: Large, broadly trusted free learning platform with a teacher and student ecosystem. Overlaps on the student learning workflow and is increasingly adding AI tutoring features, putting competitive pressure on AI-native study tools.
• Chegg: Public, well-capitalized student learning platform with paid subscriptions across study help, textbooks, and tutoring. Represents an incumbent with significantly more resources and an existing student paid-subscriber base.
