InteraxAI

You can start InteraxAI for $0 a month, which gets you 3 AI widgets and 50 generations, with extra generations at $5 per 500.

InteraxAI is a no-code platform for building AI widgets that you embed on a website and can charge for through Stripe.

The free plan allows unlimited websites, shared or your own API keys, a configurable OpenAI API, rate limiting and basic analytics.

Pro costs $20 a month and raises the limits to 100 widgets and 2,000 generations.

It also adds toggleable branding, document uploads (.txt, .pdf, .csv, .docx, .json), saved and exportable results, advanced analytics and 3 team members.

Business is $99 a month with unlimited widgets, 10,000 generations and unlimited team members.

The free tier is small, so it suits testing a widget idea before you commit.

If you plan to resell AI features to your own visitors or clients, the Stripe monetization and rate limiting are the parts to look at first.
