Which plan to pickThe app is free, so the only decision is whether the privacy trade-off is acceptable for what you're asking. If you need the model inside your own software, have a developer use the API or run the open model through a provider that keeps your data in Australia.Stay on Free unless you also want a VPN. Plus is good value if you'd pay for a VPN anyway. Pro is $19.99, the same as ChatGPT Plus or Claude Pro, so only pick it if anonymity matters more to you than features.Start free; most people never need to pay. Go at $4 is cheap if you hit the chat limits. Prices are App Store prices, so check the in-app screen before you subscribe.
