Service · AI Integrations & Custom Tools

Put AI to work inside your product — not as a gimmick, as a feature.

Frequently asked questions

Which AI providers do you use?

I integrate OpenAI and similar providers through your own API keys, so you control cost and data.

Will it work with my current product?

Almost certainly — most integrations are API additions to existing systems.

How do you keep costs in check?

Prompts are trimmed, results cached, and usage dashboards reveal spend per feature.
