How we can help.

GoodOff is an AI-powered spaced repetition study app that helps you memorize information more effectively. It uses a modified FSRS (Free Spaced Repetition Scheduler) algorithm to show you flashcards at scientifically optimal intervals — cards you struggle with appear more often, while well-known cards are spaced further apart. Available on mobile (iOS & Android via React Native/Expo) and web.

You can create flashcards in several ways: manually type them in our app, upload study materials (PDFs, documents, images) for AI generation, or import existing decks from platforms like Anki (.apkg files) or Quizlet. Our AI can automatically generate high-quality flashcards from your uploaded content in seconds.

Yes! GoodOff offers a generous free tier with core spaced repetition features, 25 AI credits a month, unlimited manual flashcards, and access to the community. For power users, we offer Pro ($4.99/mo), Standard ($8.99/mo), and Max ($29.99/mo) plans that raise your monthly AI credits and unlock the voice tutor, podcast generation, advanced analytics, and more.

Yes! Our mobile app allows you to study your flashcards offline. Any progress you make — including card ratings, XP earned, and streak data — will sync automatically when you reconnect to the internet.

GoodOff is available on both iOS (App Store) and Android (Google Play). Search for 'GoodOff' or visit goodoff.co/download for direct links. The mobile app is built with React Native/Expo and offers the full feature set including offline study mode.

Absolutely! Visit app.goodoff.co in any modern browser (Chrome, Firefox, Safari, Edge) to access the full web app. Your progress syncs seamlessly between the web and mobile apps, so you can study on whichever device is most convenient.

Creating an account is quick and free. Visit app.goodoff.co or download the mobile app, then sign up with your email address, Google account, or Apple ID. You'll be asked to set a display name and optionally choose your study interests so we can recommend relevant community decks.

After signing up, we recommend: (1) Create or import a small deck of 20-30 cards on a topic you're currently studying, (2) Do your first review session — the app will introduce new cards and quiz you, (3) Rate each card honestly (Again, Hard, Good, Easy) so the algorithm can calibrate to your knowledge level. Your first session typically takes 5-10 minutes.

Yes! GoodOff supports importing from multiple platforms. For Anki, use .apkg files directly. For Quizlet, export your set as a CSV or use our direct Quizlet import feature. We also support CSV, TSV, and plain text imports with customizable delimiters. Brainscape and other apps that export to CSV are also compatible.

Go to Settings > Study Goals to configure your daily targets. You can set goals for: minimum cards reviewed per day, new cards to learn per day, and target study time. The app will send you reminders if you haven't met your goals and track your consistency on the goals dashboard. Start with modest goals (e.g., 10 minutes/day) and increase as the habit forms.

GoodOff uses a modified FSRS (Free Spaced Repetition Scheduler) algorithm, which is more accurate than traditional SM-2 algorithms used by older apps. It tracks your performance on each card — including response time and difficulty rating — and calculates optimal review intervals. Cards you struggle with appear more frequently, while well-known cards are scheduled days or weeks apart, maximizing retention with minimum study time.

The AI Voice Tutor is an interactive study companion that quizzes you verbally on your flashcard content. It can ask follow-up questions, provide explanations, and adapt to your learning style. Think of it as having a personal tutor available 24/7. Available on Pro, Standard, and Max plans.

GoodOff makes studying engaging with a full gamification system. You earn XP (experience points) for every card reviewed, with bonuses for correct answers and consistent study sessions. Maintain daily streaks by studying at least once per day. As you accumulate XP, you level up and unlock achievements. Compete with friends and the community on leaderboards!

Yes! You can easily import your Anki decks (.apkg files) into GoodOff. All your cards, media, and tags will be preserved. We also support importing from Quizlet, CSV files, and other popular formats. Your existing scheduling data can optionally be migrated too.

GoodOff offers multiple study modes: Standard Review (spaced repetition scheduling), Cram Mode (review all cards without affecting scheduling), Quiz Mode (multiple choice from your deck), Voice Tutor Mode (AI-guided verbal quizzing), and Browse Mode (review cards without rating). Each mode serves different study needs.

The analytics dashboard gives you detailed insights into your study habits: cards reviewed per day, retention rates, time spent studying, streak history, predicted recall for upcoming reviews, and heatmaps of your study activity. It helps you identify weak areas and optimize your study schedule. Advanced analytics are available on paid plans.

GoodOff supports a flexible deck organization system. You can create nested sub-decks (e.g., Biology > Cell Biology > Mitosis), use tags to cross-reference cards across decks, and use the deck browser to search, filter, and bulk-edit cards. Drag and drop to reorder decks, and use color labels for visual organization.

GoodOff supports several card types: Basic (front/back), Reversed (automatically creates a card in both directions), Cloze Deletion (fill-in-the-blank with {{c1::text}} syntax), Image Occlusion (hide parts of an image to test recall), and Audio Cards (with text-to-speech or uploaded audio). Each type is optimized for different learning scenarios.

Yes! On the web app, use: Space to flip a card, 1/2/3/4 to rate Again/Hard/Good/Easy, E to edit the current card, S to star/flag a card, and Ctrl+Z to undo your last rating. You can view and customize all shortcuts in Settings > Keyboard Shortcuts. These work in all study modes.

GoodOff defaults to a beautiful dark theme designed to reduce eye strain during long study sessions. You can also switch to light mode or set it to follow your system preference in Settings > Appearance. The dark theme uses carefully chosen contrast ratios to keep text readable without causing fatigue.

GoodOff can send push notifications to remind you to study. Configure reminders in Settings > Notifications: set specific times for daily reminders, get notified when your streak is at risk, receive alerts when you have overdue cards, and get weekly progress summaries. You can customize which notifications you receive and set quiet hours.

Text-only study sessions use minimal data (under 1MB per session). Sessions with images use more depending on card content — typically 5-20MB per session. To minimize data usage, enable 'Download on Wi-Fi Only' in Settings > Data Usage, which pre-downloads media when connected to Wi-Fi. Offline mode uses zero data.

Yes, accessibility is a priority. GoodOff supports VoiceOver (iOS), TalkBack (Android), and screen readers on web. We follow WCAG 2.1 AA guidelines with proper contrast ratios, focus indicators, and semantic HTML. Keyboard navigation is fully supported on web. If you encounter any accessibility issues, please let us know at [email protected].

Yes! All interactive elements are properly labeled with ARIA attributes. Cards can be read aloud by screen readers, and all buttons, menus, and navigation elements are accessible. We test regularly with VoiceOver, TalkBack, NVDA, and JAWS. The study interface supports full keyboard navigation so you can review cards without a mouse.

Your data is stored on encrypted servers with AES-256 encryption at rest and TLS 1.3 encryption in transit. We use industry-standard cloud infrastructure with regular security audits. Your flashcard content, study progress, and personal information are all protected with multiple layers of security.

GoodOff is designed for users aged 13 and older. We comply with COPPA (Children's Online Privacy Protection Act) regulations. Users under 13 require parental consent and a parent-managed account. We do not knowingly collect personal information from children under 13 without verified parental consent.

Each integration processes only the minimum data required. No third party has access to your flashcard content except during active AI processing. See our privacy policy for the complete list.

Research shows that 15-30 minutes of focused spaced repetition daily is more effective than long cramming sessions. We recommend studying at the same time each day to build a habit. GoodOff's streak system helps reinforce this. Morning study sessions tend to yield better retention, but consistency matters more than timing.

The key principles are: (1) Be honest with your card ratings — don't mark cards as 'Easy' if you hesitated, (2) Study every day, even if just for 5 minutes, (3) Don't skip scheduled reviews — the algorithm works best with consistent input, (4) Keep cards simple and focused on one concept each, (5) Use images and mnemonics where possible for stronger memory encoding.

Let the algorithm decide! GoodOff's modified FSRS algorithm calculates the optimal review time for each card based on your history. Just open the app daily and study whatever cards are due. The 'due count' badge tells you how many cards need review. Avoid reviewing cards before they're due — the spacing effect works by testing recall after a delay.

We recommend 15-30 minute sessions for daily reviews. If you're learning new material, you can go longer but take a 5-minute break every 25 minutes (Pomodoro technique). GoodOff's session timer helps you track this. Quality focus matters more than quantity — 20 focused minutes beats 60 distracted ones.

Follow these principles: (1) One concept per card (atomic cards), (2) Use clear, unambiguous questions, (3) Add images or diagrams when possible, (4) Use cloze deletions for definitions and lists, (5) Include context but keep it concise, (6) Avoid 'yes/no' questions — they're too easy to guess. Our AI flashcard generator follows these principles automatically.

Start with 10-20 new cards per day and adjust based on your review workload. If your daily reviews exceed 100 cards, slow down on new cards — reviews should always take priority over learning new material. GoodOff lets you set daily new card limits in deck settings. Remember: it's better to deeply learn fewer cards than to superficially see many.

Start early — ideally 4-6 weeks before your exam. Create or import cards covering all exam topics, then study daily with spaced repetition. Two weeks before the exam, stop adding new cards and focus on reviewing existing ones. Use Cram Mode for final review the day before. GoodOff's analytics can show you which topics need more attention based on your retention rates.

For language learning: (1) Use sentence-based cards, not just isolated words, (2) Include audio pronunciation on every card, (3) Learn the most frequent 1,000-2,000 words first for maximum coverage, (4) Create reversed cards (target language → native AND native → target), (5) Add images to associate vocabulary with visual memory, (6) Study grammar patterns as cloze deletions.

Medical students: Use image occlusion for anatomy, cloze deletions for pharmacology, and organize decks by organ system or course. Many pre-made medical decks are available in our community library. Law students: Create cards for case holdings, legal rules, and statutory definitions. Use tags to cross-reference related concepts across subjects. Both benefit from studying in short, frequent sessions rather than marathon cramming.

Upload any study material — PDFs, documents, images, or even paste text — and our AI analyzes the content to generate targeted flashcards. It identifies key concepts, definitions, relationships, and facts, then creates question-answer pairs following best practices for spaced repetition. You can review and edit generated cards before adding them to your deck.

The AI Voice Tutor uses natural language processing to conduct interactive study sessions. It asks you questions based on your flashcard content, listens to your spoken answers, provides feedback, and asks follow-up questions to deepen understanding. It adapts difficulty based on your performance. Available on Pro plans and above.

GoodOff uses a modified FSRS algorithm enhanced with AI. For each card, it considers: your rating history, time between reviews, number of reviews, difficulty level, and your overall learning patterns. The AI predicts the optimal moment when you're about to forget a card and schedules the review just before that point, maximizing the 'spacing effect' for long-term retention.

While our AI is highly capable, it's not perfect. Limitations include: occasionally missing nuanced context, potential inaccuracies with very specialized or technical content, difficulty with heavily visual subjects (like anatomy diagrams), and language limitations for non-English content. We always recommend reviewing AI-generated cards before studying and editing any that need correction.

Each plan includes a different level of AI generation access. Free users get a limited number of AI generations per month, while paid plans offer increasingly generous or unlimited usage. Visit goodoff.co/pricing for the latest details on what each plan includes. You can also purchase credit packs separately if you need extra AI generations without upgrading.

Our AI achieves approximately 90-95% accuracy for well-structured source materials like textbooks, lecture notes, and articles. Accuracy may be lower for handwritten notes, complex diagrams, or highly specialized jargon. We always show generated cards for your review before adding them to a deck — you can edit, delete, or regenerate any card that doesn't meet your standards.

GoodOff's AI accepts: PDF documents, Word files (.docx), plain text (.txt), Markdown (.md), PowerPoint presentations (.pptx), images (.jpg, .png — including photos of textbooks or whiteboards), and you can also paste text directly. Maximum file size is 50MB per upload, or 100MB on Max plans.

Yes! Batch generation lets you upload multiple files and generate cards from all of them in one go. This is great for processing an entire course's worth of lecture slides or a set of chapter PDFs. The AI will organize generated cards by source and topic. Batch generation is available on Standard and Max plans.

The Voice Tutor works best in English, with growing support for Spanish, French, German, and Mandarin. It may struggle with: very technical pronunciation (e.g., organic chemistry nomenclature), strong accents in noisy environments, and extremely long or complex answers. For best results, study in a quiet environment and speak clearly. The AI improves as it learns your voice patterns over sessions.

You can share decks in several ways: (1) Generate a share link that anyone with the link can use to copy your deck, (2) Publish your deck to the GoodOff community library for anyone to discover, (3) Share directly with specific users by entering their username or email. You can choose whether others can edit the deck or only study it.

Create or join study groups to collaborate with classmates or study partners. Group members can share decks, track each other's progress, compete on group leaderboards, and chat within the group. Groups are perfect for class study sessions — one person can create the deck and everyone benefits. Create a group from the Community tab in the app.

Leaderboards rank users by XP earned within a time period (daily, weekly, monthly, all-time). You can compete globally, within your study groups, or among friends. Leaderboard rankings reset weekly to give everyone a fresh chance. Top performers earn special badges and achievements displayed on their profile.

If you encounter inappropriate content in shared decks or the community forum, tap the three-dot menu on the content and select 'Report.' Choose the reason (spam, offensive material, copyright violation, etc.) and submit. Our moderation team reviews all reports within 24 hours. You can also email [email protected] for urgent concerns.

Yes! The GoodOff community forum is a place to discuss study strategies, share tips, ask for deck recommendations, and connect with other learners. You can post in topic-specific channels (by subject, exam prep, language learning, etc.), respond to other users, and earn community XP for helpful contributions.

The deck marketplace lets you browse, search, and download community-created decks. Decks are organized by subject, difficulty, and popularity. Creators can publish free or premium decks, and top-rated decks are featured on the marketplace homepage. You can preview card samples before downloading any deck to make sure it meets your needs.

We use a combination of automated filters and human review. All published decks are scanned for inappropriate content, copyright violations, and spam. Community members can report issues, and our moderation team reviews flagged content within 24 hours. Repeat violators may have their publishing privileges revoked. We're committed to keeping the community safe and educational.

Verified creators have a green checkmark on their profile, indicating they produce high-quality, accurate content. To qualify, you need: at least 10 published decks, 500+ total downloads, an average rating of 4.0+, and no moderation violations. Apply through your profile settings once you meet the criteria. Verified creators get priority placement in marketplace search results.

Yes! Verified creators can publish premium decks and set their own pricing. GoodOff takes a small platform fee, and creators receive the rest via monthly payouts. Top creators earn meaningful supplemental income by sharing high-quality study materials. Free decks also help you build a following and reputation in the community.
