FAQ
Questions before you hand strings to an agent.
Is this just AI translating JSON files?
No. AI can draft translations anywhere. AirStrings adds the production layer around it: keys, environments, signed bundles, CDN delivery, SDK verification and rollback.
Is this priced for indies?
Start free with 3 seats and 3 locales. Pro is a flat €29 per month and Team is a flat €99 per month when you need more room.
What happens when users are offline?
SDKs serve strings from a verified disk cache after the first fetch. With nothing cached, they fall back to key names instead of crashing your UI.
What if I outgrow it or leave?
The SDKs are MIT-licensed, and cached bundles keep working on devices. Your source strings can live in your project workspace, so you are not trapped if you leave.
Let your agent ship the next string.
Create a free project, install the CLI and ask your assistant to make a safe copy change end to end.
