Permissions and privacy

Page access

Autocomplete only works if the extension can read the text field you are typing in, so it requests access to the sites where you write. Use Chrome's site-access controls to limit it to the apps where you want suggestions, and keep it off banking, health, and work systems.

Data notes

The listing discloses personally identifiable information, personal communications, location, web history, user activity, and website content. OthersideAI's general privacy policy, last updated in 2022, does not single out the extension and mentions collecting online activity data such as pages viewed.

Pricing

Free plan with limited monthly credits; paid Premium and Ultra plans. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
