FAQ

Answers to frequently asked questions about using YeeroAI.

Account & Login

How do I sign up?

Visit yeero.ai and sign up with email (verification-code login), Google, or GitHub. You'll receive 1,000 free credits instantly (valid for 30 days).

Can I use a test account?

Yes, click "Try test account" on the login page. Test accounts have limited functionality — some operations (such as payments) are restricted, so you can explore before committing.

How do I change my email?

Go to Account → Account Security, then click "Bind" or "Switch" next to the email. You'll need to verify your identity with your current login method first.

Can I link multiple login methods?

Yes, you can link email, Google, and GitHub to the same account. We recommend linking multiple methods for better security, but you must keep at least one method linked.

How do I sign out?

Go to Account → Sign Out, then click "Sign Out" for the current device or "Sign Out All Devices" to force-logout every signed-in device.

What if I don't receive the email verification code?

Check your spam folder first — the code email may land there. If it still hasn't arrived, wait for the countdown to finish and click "Resend". If the problem persists, contact us via Account → Feedback.

How do I delete my account?

For data-security reasons, account deletion is handled manually. Submit a deletion request via Account → Feedback (mark it "Account Deletion"), and we will delete or anonymize all your data within 30 days. See our Privacy Policy for details.

Credits & Billing

How many free credits do I get?

You get 1,000 credits on registration (valid for 30 days). Inviting friends earns additional credits — invitation credits never expire.

How are credits consumed?

Credits are used for AI conversations, memory generation and matching, AI app generation and discussion, Agent and cloud runs, and storage overage. The amount depends on the model and output length, and the exact cost is shown on each AI response. See Spending Credits for the full list.

Do credits expire?

One-time purchased credits never expire. Subscription credits may expire when your subscription ends. The 1,000 registration credits are valid for 30 days — check the "Expires" column under Account → Credits → Earned for other gifted credits. See Credit Validity.

Can I get a refund?

Yes. Go to Account → Credits → Earned and click "Apply Refund" on a purchase record. Refunds must be requested within 24 hours of purchase, are calculated proportionally to remaining credits, are limited to one per account, and cannot be withdrawn once submitted. Internal review takes 1-3 business days, and settlement back to your original payment method takes a further 5-15 business days. See our Refund Policy and Refunds.

What payment methods are supported?

Paddle (international credit cards) and WeChat Pay / Alipay (for users in China). All payments are processed by licensed third parties; YeeroAI never stores full card numbers.

What's the difference between a subscription and one-time purchase?

A subscription provides a fixed monthly credit allowance, ideal for ongoing use; one-time purchases are pay-as-you-go and the credits never expire. You can use both together, and subscriptions can be canceled anytime — you keep access until the end of the current billing cycle.

Where can I see my credit usage details?

Go to Account → Credits → Spent to see every deduction (conversations, memories, apps, storage). The Billing sub-tab on the same page lists all your orders and subscription history.

How do invitation rewards work?

You earn 10% of your friend's registration credits and 10% of every credit purchase they make. Invitation rewards are uncapped and never expire. Get your unique code and link in Account → Invitations. See Invitation Rewards.

AI Models

How many models are available?

300+ models from 10+ providers including OpenAI, Anthropic, Google, Meta, and Mistral, all accessible through OpenRouter.

Are there free models?

Yes, toggle "Free Only" in the model selector to see free models. Each call to a free model costs 1 credit.

Can I use multiple models at once?

Yes, select up to 10 models in the same conversation for parallel comparison — answers appear side by side for easy evaluation.

What modalities are supported?

Text, image, audio, video, and file input/output, depending on the capabilities of the selected model.

How do I choose the right model?

For everyday chat, pick a general model (such as GPT or Claude); for code, choose a model strong at programming; for long documents, check the context length. Each model's detail page lists capability tags, context window, and credit price so you can compare.

What if a model is unavailable?

Models can be temporarily unavailable due to upstream provider maintenance. Switch to another model to continue; if the issue persists, let us know via Account → Feedback.

Core Features

What is branching thinking?

Branching gives every conversation Git-style branches: fork a new path from any message to explore different directions, merge to keep the best ideas, and roll back to any node — the main thread is never affected. See Branching Thinking.

What is Follow-Up?

Select any passage in an AI reply and launch a follow-up in one click. Follow-ups unfold in a separate thread, support multi-level drilling, and leave the main conversation's context intact. See Follow-Up.

What are AI Apps?

Describe an idea in natural language and AI generates a runnable HTML or Python app. Apps support patch-based incremental iteration, full version history, live preview, and built-in discussion. See AI Apps.

How does the Knowledge Base work?

AI automatically extracts key knowledge from your conversations, builds a vector index, and injects relevant context into future chats. You can browse, search, and manage entries by tag. See Knowledge Base.

What are AI Memories?

Memories are persistent knowledge entries AI distills from your conversations. They are automatically matched and injected as context in later chats, so the AI understands you better over time. View, edit, and delete them in Settings → Memories.

Desktop & CLI

Is there a desktop app?

Yes. Yeero Desktop is built with Tauri and supports macOS (Apple Silicon / Intel), Windows (x64 / ARM64), and Linux (AppImage / deb), with native windows, OS notifications, and in-app auto-updates. See Desktop.

What is the Launcher?

The Launcher is the desktop app's global summoner, triggered by Alt+Space. It ships with 16 processors covering calculation, app launching, search, and AI chat. See Launcher.

Does the desktop app support screenshots and screen recording?

Yes. The desktop app offers smart window detection, scrolling-screenshot stitching, and microphone/webcam picture-in-picture recording. Screenshots can go straight into the image editor for annotation. See Screenshot & Recording.

Is there a CLI?

Yes. Install the yeero CLI with one command: on macOS / Linux run curl -fsSL https://yeero.ai/cli/install.sh | sh; on Windows run irm https://yeero.ai/cli/install.ps1 | iex. See CLI Quick Start.

Does the CLI share data with the web app?

Yes. After signing in, the CLI shares the same account with the web and desktop apps, and conversation history syncs in real time.

Privacy & Security

Is my data encrypted?

Yes. All data is encrypted in transit with TLS 1.2+ and at rest with AES-256. Your private data is never sold or shared with any third party.

Can I delete my data?

Yes, you can delete individual conversations, messages, files, and knowledge entries at any time. After account deletion, all data is removed or anonymized within 30 days. Deletion is permanent and cannot be undone.

What about AI training?

YeeroAI does not use your data to train AI models. However, your queries are sent to underlying model providers (such as OpenAI, Anthropic, and OpenRouter) to generate responses, and that data is subject to those providers' privacy policies. See our Privacy Policy.

What is the end-to-end encryption key?

You can configure a universal E2E key in Settings → End-to-End Encryption Key for encrypted sync scenarios (such as cross-device clipboard sync). The key is stored only in your local system keychain; leaving it blank disables encryption. To decrypt synced content across devices, configure the same key on each one.

Where is my data stored?

YeeroAI stores your data on cloud infrastructure certified under SOC 2 Type II and ISO 27001, encrypted in transit and at rest, and protected by strict access controls. See our Privacy Policy for details.

Storage & Files

How much storage do I get?

1 GB of free storage. Beyond the free quota, extra storage incurs a daily credit fee.

What happens if I exceed my storage?

You'll see warning banners. If storage stays overdue for more than 7 days and your credit balance is insufficient, the oldest files are auto-deleted until you're back within the 1 GB free quota.

What file types can I upload?

Any format is supported, up to 512 MB per file. Images, videos, audio, and documents can all be previewed online.

Will AI read the files I upload?

AI only reads a file when you actively attach it to a conversation or app. Unattached files are never analyzed automatically. Files are semantically indexed to support search, but that is separate from conversation-context injection.

How do I clean up files in bulk?

The Files page supports drag-to-select box selection; once selected you can batch download, delete, or move. You can also set automatic deletion conditions in Cleanup Rules (by type, source, size, path, or age), which run daily at 2 AM.

Troubleshooting & Support

What browsers are supported?

YeeroAI works best on modern browsers: Chrome, Firefox, Safari, and Edge. Use the latest version for full functionality (such as Service Worker and SSE streaming).

Does YeeroAI work on mobile?

Yes, the web interface is fully responsive and works in mobile browsers. A native mobile app is in development; the desktop app already offers a native experience.

What if AI generation fails?

Try refreshing the page first. If the issue persists, check that your credit balance is sufficient, or switch to another model. Background streaming resumes automatically after a network interruption — no need to resend manually.

What if a streaming response is interrupted?

YeeroAI uses SSE streaming with reconnection support. After the network recovers, it resumes automatically and already-generated content is not lost. If there's no response for a long time, click "Stop" and resend.

What if cloud sync isn't working?

Make sure the relevant toggle is on in Settings → Cloud Sync. Sync uses debounced pushes (about 1 second); after switching devices, wait a moment or refresh to pull the latest data. Some temporary UI state is intentionally excluded from sync.

How do I report an issue or suggestion?

Submit issues, suggestions, or complaints via Account → Feedback and we'll follow up. For refund appeals, privacy, or legal matters, use the same channel and note the request type.
