Frequently Asked Questions
What is ai2ia?
ai2ia (AI to instruct AI) is a desktop application that optimizes your prompts for multiple AI models and lets you compare their responses side by side. It supports OpenAI, Anthropic, Google AI, and xAI.
What happens after the 7-day free trial?
After the trial ends, access to the app is paused until you subscribe. No charge is made during the trial — no credit card required.
Do I need API keys for each AI provider?
Yes. ai2ia connects directly to each provider's API using your own keys. Your keys are stored locally and never sent to our servers.
Which platforms are supported?
ai2ia is available for Windows, macOS, and Linux. Built with Tauri for native performance on all platforms.
How does prompt optimization work?
ai2ia uses AI to analyze your prompt and automatically tailors it for each target model. This ensures you get the best possible response from each AI provider.
Is my data safe?
Yes. ai2ia runs entirely on your local machine. API calls go directly from your device to each AI provider. Your prompts and API keys never pass through our servers.
Can I cancel anytime?
Yes. You can cancel your subscription at any time. We also offer a 30-day money-back guarantee for all purchases.
What's the difference between ai2ia and using AI directly?
ai2ia optimizes your prompts for each AI model and lets you compare responses in parallel. Instead of manually switching between providers and tweaking prompts, ai2ia does it all in one place with a unified interface.
