Install and update
Version 1.1.6 is not Authenticode-signed. Download only from trycirco.com and compare the SHA-256 checksum on the download page before continuing.
Use x64 for most Intel and AMD PCs. Use ARM64 for a Windows on Snapdragon PC. The universal build contains both.
Choose when to download it and when to restart. Circo checks after launch and periodically while it is open.
Remove Circo from Windows Settings under Installed apps. Local app data is retained unless you remove it separately.
Using Circo
Open Preferences, click the shortcut control, and record another key combination. An optional Ctrl + Shift + S backup can also be enabled there.
Check your connection, try a smaller selection, and confirm that Google Lens is available on your network.
Select a tighter region with clear, upright text. Very small, stylized, blurred, or low-contrast text may be harder to recognize.
Confirm you are online and select a shorter, readable passage. Circo splits longer text into smaller requests automatically.
Open Preferences to change its anchor, size, opacity, appearance, or visibility.
Move the cursor to the display you want before triggering Circo. If alignment remains wrong, include your display scaling percentages when contacting support.
Account and access
Keep Circo open during sign-in. Return to the app and start the connection again if the page says the request expired.
Check the country code and number, then wait for the resend timer. Delivery depends on the carrier and enabled Firebase SMS regions.
A signed-in Free account includes 150 searches. Guest use has a small daily allowance.
Open Account in Circo and refresh access. Make sure you are using the same account that completed payment.
Email contact@trycirco.com with the account email and payment reference. Do not send card or banking details.
