Our verdict
Gizmo suits students who want to turn notes, PDFs or videos into flashcards and quizzes quickly, with a fairly generous free tier and a 4.8/5 App Store rating. The trade-offs are Unlimited pricing shown only in the app, a small and low-scoring Trustpilot sample, and a privacy notice that allows personal data to be used to train AI models.
Best for: Students revising from notes, slides, PDFs or videos
Skip it if: Anyone who needs a non-English interface or wants to see prices before installing

Problems it solves
Experience & key features
Gizmo is an AI study app and website from Gizmo AI Ltd of London, UK. It was first released on the App Store on 17 February 2022 as Gizmo: AI Tutor, described as an app that makes flashcards and quizzes from your own materials. The homepage lists tools such as a flashcard maker, a PDF summariser, and converters that turn PDFs, PowerPoints or YouTube videos into flashcards. It runs on iOS, Android and the web.
Learning centres on Magic Import, spaced repetition and game mechanics such as Hearts, Coins, XP and leagues. Recent releases added team battles with friends (late August 2026), Study paths (September 2026) and Gizmo Live (31 October 2026). The help center says Gizmo Live, practice tests, and creating cards and decks are available on both the free plan and Unlimited.
Pricing and value
According to the help center, core features are free. Running out of 15 Hearts triggers a 10-minute wait, and Magic Import is limited to 2 decks per day with 20-minute gaps. Unlimited removes these limits and adds unlimited AI Tutor and hints. Gizmo offers a yearly plan paid up front for 365 days and a weekly plan, but prices appear only in the app and vary by device and region. AppDuo therefore lists no specific price; check the in-app price before paying.
Data and reliability
Gizmo says it does not sell personal information, but its privacy notice allows personal data to be used to train AI models and shares study content with AI suppliers. Because what users upload is exactly what the AI processes, anyone studying from sensitive material should read it carefully. On user feedback, the App Store shows 4.8/5 from 17,245 ratings, while Trustpilot has only 8 reviews averaging 2.9/5 on an unclaimed profile.
Compared with Quizlet or Anki, Gizmo leans more on AI-generated cards and game mechanics. The interface and help materials are English only. It fits students who need fast revision from existing materials; those wanting full lessons or a non-English interface should look elsewhere.

Privacy
Per the privacy notice (updated 8 October 2026), Gizmo AI Ltd (UK) collects account data, study content users upload (text, photos, video), usage logs and device information. Users must be 13 or older. Gizmo says it does not sell personal information, but data goes to AI suppliers, app stores and Stripe, and personal information may be used to train the models behind its AI features. Age-check photos are deleted after 24 hours; accounts inactive for 3 years (under 18) or 10 years are deleted or anonymised. For decks made through ChatGPT, Gizmo sends OpenAI the deck name, card count and link; anyone with the link can open and edit the deck, and deletion requires an email to Gizmo.

Why this score
Magic Import and quick onboarding, with a 4.8/5 App Store rating. Trustpilot reviewers mention a required phone number and hard-to-cancel plans, though the sample is tiny. The interface is English-only.
Why this score
Flashcards, quizzes, practice tests, AI Tutor, import from PDFs, video and PowerPoint, plus Gizmo Live. Focused on revision; no source describes structured course content.
Why this score
A generous free tier, but Unlimited prices are unpublished and the US App Store lists many in-app amounts from $6.99 to $154.99 without durations, making comparison hard.
Why this score
Frequent releases through October 2026 and a high App Store rating; a few Trustpilot reports of breakage, and no independent evaluation of its AI accuracy.
Why this score
A help center, contact form, email and Discord; no phone line or response-time commitment found.
Why this score
Clear retention periods and a no-sale statement, but the notice allows personal data to train AI models, lists ad trackers (Meta, TikTok, Google Ads) and leaves ChatGPT decks open to anyone with the link.
