Frequently Asked Questions

AI Arena is a competitive platform where users upload AI-generated content (images and videos) and vote on head-to-head matchups. It's like a tournament bracket system where the best AI creations rise to the top through community voting.

Think of it as combining the addictive voting experience of apps like Tinder with the competitive nature of chess rankings, but for AI-generated art.

For browsing: No! You can explore content and see how the app works in guest mode.

For voting and uploading: Yes, you'll need to sign in with Google to participate in competitions and upload your own content.

We use Google Sign-In for security and simplicity - no need to remember another password!

Yes! AI Arena is completely free with no ads, subscriptions, or hidden costs. Our focus is on building an amazing community of AI art enthusiasts.

Our ELO system is based on the chess rating algorithm, adapted for content competition:

• Starting Rating: All content begins at 1200 ELO
• Dynamic Scoring: Points gained/lost depend on the rating difference
• Upset Rewards: Beating higher-rated content gives bigger gains
• Fair Matchmaking: Content with similar ratings are paired together

ELO ratings are relative - what matters most is how you compare to other content in your category and time period.

Yes, ELO is a zero-sum system. When your content loses a vote, it loses points while the winning content gains points. This keeps the system balanced and ensures that only the truly best content reaches the top.

Don't worry: You lose fewer points when losing to higher-rated content, and you can always improve your rating with future wins!

AI-Generated Content Only:

• Images created with AI tools (Midjourney, DALL-E, Stable Diffusion, etc.)
• Short videos (up to 15 seconds) generated by AI
• Content you created or have rights to share

Supported Formats:

• Images: JPG, PNG, WebP (max 50MB)
• Videos: MP4 format, up to 15 seconds, max 50MB

Not Allowed:

• Real photographs or traditional artwork
• NSFW, violent, or inappropriate content
• Content you don't have rights to
• Spam or low-quality submissions

Upload Limit: 3 uploads per 12-hour period

This limit encourages quality over quantity and ensures all users get fair visibility for their content. The timer resets every 12 hours, so you can upload regularly while maintaining platform quality.

Pro tip: Take time to select your best AI creations rather than uploading everything!

AI Arena has 7 carefully curated categories:

• Digital Art: Classic AI art, paintings, and digital masterpieces
• Photorealism: Hyper-realistic AI-generated photographs
• Fantasy: Magical creatures, mythical worlds, and fantasy art
• Sci-Fi: Futuristic scenes, space art, and science fiction
• Anime/Manga: Japanese-style art and illustrations
• Nature: Landscapes, wildlife, and natural beauty
• Brainrot: Weird, surreal, and wonderfully strange creations

Choose the category that best fits your content for optimal matching with similar styles.

Every calendar month is a fresh competition period:

• Fresh Start: Everyone begins with equal opportunity
• Achievement Tiers: Champion (1st), Podium (top 3), Elite (top 10), Competitor (top 100)
• Historical Records: Your achievements are permanently recorded
• Preferential Status: Top 100 content from previous months gets priority pairing

Monthly competitions keep the platform fresh and give newcomers a chance to compete with established creators.

Recognition and Achievements:

• Permanent achievement badges on your profile
• Historical record of your accomplishments
• Featured placement in leaderboards
• Bragging rights in the AI art community!

Currently, rewards are recognition-based. We're focused on building a thriving community before considering any material prizes.

Two Voting Modes:

• Tap Mode: Tap on your preferred content for quick, precise voting
• Swipe Mode: Tinder-style swiping with haptic feedback and progress indicators

Fair Play Rules:

• You can only vote on each content pair once
• Content is intelligently paired to prevent user fatigue
• Your vote immediately updates both contents' ELO ratings
• Anonymous voting - creators don't see who voted

No, you cannot vote when your own content appears in a matchup. The app automatically detects this and will skip to the next pair.

This prevents self-voting and ensures fair competition based on community judgment.

Every piece of content has a report button. You can report content for:

• NSFW or inappropriate material
• Non-AI generated content
• Spam or low quality
• Copyright violations

Our moderation team reviews all reports promptly and takes appropriate action.
