Example questions:

• "Find information about pricing in the document"

For best results, make your questions:

• Specific: "What is the refund policy?" vs "Tell me about policies"
• Clear: Use simple, direct language
• Contextual: Reference specific documents when you have multiple files

Yes! The AI can search across all your uploaded documents simultaneously to provide comprehensive answers. This is especially useful for:

• Comparing information across multiple contracts
• Finding related topics in different documents
• Getting comprehensive overviews from multiple sources

Our AI strives for high accuracy by:

• Only using information directly from your documents
• Providing source references when possible
• Indicating when information is unclear or unavailable

To update your password:

1. Log in to your account
2. Go to your Profile page
3. Find the "Change Password" section
4. Enter your current password
5. Enter your new password (minimum 8 characters)
6. Confirm your new password
7. Click "Update Password"

Two-factor authentication adds an extra layer of security to your account:

• Requires both your password and a temporary code
• Uses an authenticator app like Google Authenticator
• Protects against unauthorized access even if your password is compromised

To enable 2FA, go to your Profile page and follow the setup instructions.

Your usage information is available on your Profile page, including:

• Monthly message count and limit
• Storage used and available
• Document upload count
• Current subscription tier

If your upload fails, try these steps:

1. Check that your file is under the size limit (10MB for free, 50MB for paid)
2. Ensure the file format is supported (PDF or TXT)
3. Verify you haven't exceeded your monthly upload limit
4. Try refreshing the page and uploading again
5. Check your internet connection

If the problem persists, the file might be corrupted or password-protected.

This can happen for several reasons:

• Scanned PDFs: Text in images isn't searchable
• Complex formatting: Tables or unusual layouts might not process correctly
• Question phrasing: Try rephrasing your question differently
• Processing delay: Large documents may take time to fully index

Rate limits prevent system overload and ensure fair usage:

• Too many requests: Wait a few minutes before trying again
• Monthly limits: You may have reached your plan's message limit
• Upgrade option: Consider upgrading to a higher tier for more capacity

Rate limits reset automatically, so waiting usually resolves the issue.

We take data security seriously:

• Encryption: All data is encrypted in transit and at rest
• Secure storage: Documents stored in secure cloud infrastructure
• Access controls: Only you can access your documents
• Regular backups: Your data is backed up regularly

For detailed information, see our Privacy Policy.

Your privacy is paramount:

• Staff access is limited to technical troubleshooting only
• All access is logged and monitored
