FAQ

Questions about generative AI.

Didn't find yours? Ask us directly — we reply within 24 hours.

How much does a generative AI feature cost?

A working prototype usually costs $8,000–$20,000. A full feature in your app typically ranges from $20,000 to $60,000. Per-generation costs are estimated upfront.

Can it write in our brand voice?

Yes. We add your tone, terms and examples to every request, and fine-tune a model when you need a very consistent voice at scale.

Who owns the generated content?

You do. We use commercial-safe models and licenses that allow business use of the output.

How do you avoid inappropriate output?

Moderation filters, brand rules, blocked topics and optional human review before anything is published.

Will it be expensive at scale?

We cache results, route simple tasks to smaller models and batch requests, so costs stay predictable as usage grows.

What can generative AI do in an app?

Generative AI can write product descriptions, summaries and replies, create images, personalize content and power chat features. Perpetio builds these features into your app with brand rules, moderation and cost control.
