Install the Chrome extension, open it on any site, and it presents a breakdown of the site's legal documents instead of walls of legalese. Summaries are split into key considerations, items to watch out for, AI recommendations and predicted FAQs, with colour coding that separates favourable, neutral and harmful terms. If a policy has not been summarised before, DocDecoder generates a new summary from the URL you supply, typically in well under a minute. The project also offers a searchable summary directory, an AI assistant you can question about a specific policy, and an open-source repository so developers can inspect or contribute to the code. Usage is metered rather than unlimited: free users can generate a limited number of brand-new summaries per month while viewing existing summaries without restriction, and a Premium tier lifts those limits. No account is required to get started, and the extension is published on the Chrome Web Store alongside the docdecoder.app site. **Pricing & Plans:** Free to use with a monthly cap on newly generated summaries and unlimited access to summaries that already exist in the community directory. A Premium plan is offered for heavier use; the Chrome Web Store listing also notes in-app purchases. Check docdecoder.app for current pricing. - **One-click policy summaries:** Open the extension on any website to see its terms, privacy policy and similar documents condensed into a short scannable overview. - **Colour-coded risk highlighting:** Favourable, neutral and potentially harmful clauses are visually separated so the terms that affect you stand out immediately. - **Structured summary sections:** Each summary covers key considerations, things to watch out for, an AI recommendation and predicted FAQs you might have about the policy. - **Generate a summary for any URL:** If a policy has not been covered before, paste its URL and DocDecoder returns a fresh GPT-4 summary, usually within about 30 seconds. - **Ask follow-up questions:** A built-in assistant answers questions about a specific policy so you can dig into a clause without re-reading the whole document. - **Open source with no trackers:** The code is publicly available on GitHub, requires no account, and the project states it ships without trackers or ads. **Strengths:** Turns multi-thousand-word legal documents into a few scannable bullet points; Colour coding makes harmful and favourable clauses obvious at a glance; Free tier with no account required, plus an open-source codebase; Works on any site and can generate a summary for a policy URL on demand **Limitations:** Free tier limits how many brand-new summaries you can generate each month; Summaries are machine-generated and should not replace legal advice; Available only as a Chrome extension, with no Firefox or Safari build; The in-store listing has not been updated recently, and the user base is still small [Profile (Markdown)](https://openaitools.app/tool/docdecoder.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/gizmo-ai.md) ## Frequently Asked Questions ### How do DocDecoder and Gizmo compare in monthly traffic?
