Use multiple AIs in one conversation—as much as you need. Subscribing to multiple AI services on separate monthly plans can result in recurring charges even when you do not use them. AreaViz uses API keys issued by OpenAI, Anthropic, and Google, helping you manage costs based on actual usage under each provider’s usage-based API pricing. Freely use different AI models in a single conversation. Switch models based on your question and compare answers from different perspectives. It is especially useful for people who want to use multiple AIs without the burden of subscribing to each service separately. ■ Get started with your own API keys Register an API key issued by OpenAI, Anthropic, or Google and start chatting right away. There is no need to create an AreaViz account or sign in separately. AI API usage is billed directly to your account according to each provider’s pricing and payment policies. AreaViz does not add a separate fee to API charges, and AI API usage is not included with an AreaViz Pro purchase. Your registered API keys are securely stored in the Keychain on your Apple device and are sent only to the corresponding AI provider’s API server to process your requests. ■ Conversations that continue across Apple devices AreaViz supports iPhone, iPad, and Mac. Conversations sync automatically through iCloud, so you can continue chatting naturally on another device. ■ Ask with images and content - Attach photos taken with the camera or images from your photo library - Capture and mark up any area of your Mac screen, then ask about it immediately ■ Faster on Mac Use global keyboard shortcuts to access AreaViz quickly while working in other apps. - Chat bar: ⌃Z - Open app window: ⌃⇧Z - Capture screen area: ⌃X ■ Start free, then purchase only once when you need more AreaViz is not a monthly subscription. Basic chat features are free, and registering your first API key unlocks a 7-day trial of all features. After the trial ends, you can continue using the following features within the free limits. - Screen capture and chat bar - Up to 3 prompts - Attach 1 image per message A one-time AreaViz Pro purchase permanently unlocks the following features. - Up to 24 prompts - Attach up to 4 images per message - Unlimited screen capture and chat bar use - Automatic question suggestions - Change the AI model for each response - Adjust the amount of conversation history sent to the model Users who previously purchased AreaViz tokens can use Pro at no additional cost. ■ Privacy AreaViz does not require a separate account. API keys and conversation content are not stored on the developer’s servers. API keys are stored in your device’s Keychain, and conversation history is stored on your devices and in your personal iCloud. Content sent to an AI is delivered to the selected provider’s API to generate a response and is subject to that provider’s data-processing policies. ■ Privacy Policy https://boardtack.com/AreaViz/privacy.html ■ Terms of Use https://boardtack.com/AreaViz/terms.html
