Common questions
Know what happens before you optimize.
Does Nitro AI edit my live theme automatically?
No. The guided and advanced workflows are designed for eligible draft themes. Merchants review and publish through Shopify when ready.
Can I optimize files individually?
Yes. File Workspace lets eligible merchants inspect, minify, and revert supported CSS and JavaScript files one at a time.
What happens if an optimization needs attention?
The app records the result, explains what needs review, and keeps recovery or retry actions available when they are safe.
How are plans and payments managed?
Shopify hosts plan selection and manages subscriptions and payments. Nitro AI verifies the active plan before protected operations.
