Store listing
By Batuhan Ayhan, from the App StoreDescription by Batuhan Ayhan Written by the developer, not by AppBrain. Click to read.
Cortis runs language models directly on your iPhone. Once a model is downloaded, chats work without an internet connection, and you don't need an account to start.
WHAT YOU GET
• Chat without a connection once a model is downloaded: the model runs on your device
• No account needed
• Ask about a photo with a vision model
• Choose the model that fits your phone: smaller models are fast and light, larger ones give stronger answers
FREE PLAN AND PRO
Cortis has a free plan with smaller models. Cortis Pro unlocks larger models and the performance view. Pro is offered as a weekly subscription (with a free trial when you are eligible), an annual subscription, or a one-time lifetime purchase. Prices are shown in the app before you buy and may vary by country.
Weekly and annual subscriptions renew automatically unless you cancel at least 24 hours before the end of the current period. Payment is charged to your Apple ID at confirmation of purchase (or when a free trial ends). Manage or cancel in your Apple ID account settings. Any unused part of a free trial is forfeited when you buy a subscription.
