What is 3schools GPTs?

3schools GPTs is a browser-based AI platform that hosts specialized prompt generators.

App Layout & Sections

We designed the tool to feel exactly like a modern app store. Here is a breakdown of what you will find in each section.

Home / Explore

  • Featured Tools: The top scrolling shelf. It highlights brand sponsors and creators who have boosted their GPTs.
  • YouTube / 3D Carousels: Quick scrolling horizontal lists for our most popular categories.
  • Trending Community: A constantly shuffling showcase of the best tools submitted by other users.
  • From Creators You Follow: If you follow someone, their newest creations automatically appear in a dedicated shelf here.
  • All Generators: The main vertical grid at the bottom containing all official 3schools studio tools.

Community Library

Click "Community" in the sidebar to see tools built strictly by other users.

  • Creator Chips: At the top, you'll see a row of circular avatars representing the top community authors.
  • Creator Profile Banners: When you tap a creator's avatar, a large profile banner appears showing their follower count, verified badge, and a "Follow" button. All the tools below it filter to show only their creations.

My GPTs & Bookmarks

  • My GPTs: Your private workspace. This holds every bot you create. Tools here are completely private to your Google Drive until you explicitly check the "Publish to Community" box.
  • Bookmarks: Any tool you click the bookmark icon on will be saved here for instant access later.

Running Prompts & Versions

When you tap on any card, you enter the dedicated GPT Details and Chat workspace.

The Details Page Layout

  • App Hero: Shows the tool's 16:9 squircle icon on the left, next to the bold title, author badge, and cost.
  • Media Showcase: If a tool contains multiple example images, a horizontal preview slider displays sample outputs in 16:9 and 9:16 mobile formats.
  • Clickable Tags: Under the description, tap any tag like 🏷️ YouTube to jump directly to all tools in that niche.
  • Creator Action Row: For community tools, this row provides the creator badge, a Follow button, and a Report flag.

Versions (Short, Long, Explained)

Some advanced tools offer multiple versions. Look for the dropdown pill next to the coin cost (e.g. Short vs Detailed). Selecting a version automatically changes the instructions and coin cost.

1-Tap Conversation Starters

Under the "Try These Prompts" section, click any starter card. The app instantly copies the prompt into the input box and begins generation.

AI Follow-Up Suggestions

After an AI response completes, it automatically offers 2 intelligent next steps. Tapping a suggestion immediately sends the prompt and cleanly hides the previous buttons.

Connecting Free AI Keys

Every standard tool in our app requires your own API key to function. Because you provide the key, the generations are 100% free and unlimited.

How to Add Your Key:

  1. Click the Settings (Gear) icon in the header or sidebar.
  2. Select your provider: Google Gemini, Groq, or OpenRouter.
  3. Paste your free API key into the text box and click Save Settings.

Advanced: Using Multiple Keys (Key Rotation)

If you generate a lot of content and hit rate limits, you can add multiple keys. Simply separate them with a comma:

AIzaSyKey1..., AIzaSyKey2..., AIzaSyKey3...

The app will randomly pick one of your keys every time you send a message, keeping you well under the provider's limits!

Advanced: Using Custom Models

We provide a dropdown of popular models, but you aren't restricted to them. If a new model comes out today, you can use it immediately:

  1. In the Settings modal, open the Model dropdown.
  2. Select "Enter Custom ID..." at the bottom of the list.
  3. A text box will appear. Paste the exact model string (e.g., gemini-3.8-flash).
Provider Fallbacks

If Groq is down or Gemini is giving you errors, just open settings and swap to a different provider. It takes 2 seconds and keeps your workflow moving.

Coins, Referrals & Rewards

While all standard tools are free with your own API key, our dual-wallet economy powers high-end "Server GPTs" without requiring monthly subscription fees.

The Dual-Wallet System

Building Custom GPTs

Anyone can build custom AI tools and store them securely in their private Google Drive.

The Easy Way: Use the AI GPT Builder

Don't know how to write a massive 1,500-word system prompt? We built a meta-bot to do it for you.

  1. Click + Create GPT in the left sidebar.
  2. At the top of the modal, click the glowing ✨ Build with AI button.
  3. This opens a chat with our official Custom GPT Bot Builder. Just tell it your idea (e.g., "I want an AI that writes Instagram Reels about luxury cars.")
  4. The AI will write the entire professional system prompt and provide a blue 🚀 Open & Auto-Fill in Builder button.
  5. Click it, and all the fields (Title, Description, Prompt, Tags) will instantly fill out for you! Hit Save.

Note: If you are editing an existing GPT, the button changes to 🪄 Improve with AI. It will pull your existing prompt into the chat so the AI can upgrade it without you retyping anything.

The Manual Way:

  1. Click + Create GPT.
  2. Upload a logo image or rely on the emoji the AI suggested.
  3. Enter a Name and a short description.
  4. Enter your System Prompt.
  5. Add conversation starters separated by the pipe symbol (|). E.g., Fix my code | Write a script
  6. Select up to 3 relevant categories from the horizontal tag selector.
  7. Click Save to My GPTs.
100% Private by Default

When you click Save without checking "Publish to Community", your bot saves only to your personal Google Drive under 3schools-prompt/My GPTS. Nobody else can see or use it until you decide to share.

Publishing to Community

Share your creative tools with thousands of users in our Community Library.

How to Submit for Public Review:

  1. Open your tool from the My GPTs tab and click the pencil (Edit) icon.
  2. Check the box: Publish / Resubmit to Community Library.
  3. Click Save to My GPTs.
  4. Your submission enters our automated review queue. Once approved, it appears in the Community tab and creator rankings!

Safe Live Updates (Zero Downtime):

If your tool is already live in the community and you edit it:

  • The live public bot stays online and functioning so your users never experience a broken link.
  • Your updates are submitted as a review draft for admin inspection.
  • Once approved, the live post updates seamlessly.
2-Hour Cooldown & Community Guidelines

To prevent queue congestion, there is a mandatory 2-hour cooldown between submitting or updating community tools.

Pro-Tip for Testing: If you are tweaking your prompt or fixing bugs, leave the "Publish / Resubmit to Community Library" box unchecked. You can save and test privately in your Google Drive as many times as you want without triggering any cooldowns or review queues.

Spam & Abuse Policy: Submitting repeated low-effort bots, placeholder prompts, abusive content, or spamming the review queue will lead to an immediate account Ban.

What happens if your account is Banned?

  • Your daily coin allowance is permanently zeroed out (0 Coins).
  • You are blocked from running coin-metered Server/Premium GPTs.
  • You can no longer create, edit, or submit custom tools.
  • You are blocked from following creators.
  • Your profile is completely removed from the Community Creators directory, chips, and rankings.
  • Your avatar is flagged with a red suspension ring.

Want your community tool featured on the Explore homepage shelf? Use the Boost feature to bypass organic rankings.

How to Boost:

  1. Go to the My GPTs tab.
  2. On any published community tool, click the ⚡ (Boost) button.
  3. Confirm in the modal: Costs 250 Paid Coins.
  4. Your tool is pinned with the 🚀 Boosted badge on the Explore "Featured Tools" shelf and Trending Community.

Note: Because we use high-speed edge caching around the world, your boost is guaranteed for a full 5 days, but it starts fully from tomorrow across all active users' devices.

Time Stacking

If you click Boost again while your promotion is already active, our server simply adds another 5 Days to your expiration timer. You never lose remaining time.

Notes, Scripts & Chat History

Organize generated prompts, write YouTube scripts, and access past conversations across all your devices.

Notes & Scripts Scratchpad

  • Click Notes & Scripts in the sidebar or tap the Document icon inside the chat bar.

Sponsor Slots & Advertising

We do not display annoying display ads. Instead, we offer high-impact native sponsor cards inspired by Google Play Store.

You can always tell what is an ad because it will explicitly have the Sponsored badge on the card. Sponsored tools do not pollute community search results; they only live in dedicated shelves.

Available Fixed Sponsorship Slots:

  • Home Featured Shelf (Slot 1 & 2): Premium placement on the 14-item Explore shelf seen by 100% of homepage visitors.
  • Category Monopolies: Own the guaranteed Slot 1 card across dedicated category views (e.g., Runway in YouTube, Leonardo.ai in 3D).

All sponsor cards include custom action badges (e.g. Partner, Free Trial) and direct outbound links to your SaaS tool.
