Eikos Pro · not live yet

US$ 19.99 /month

Or US$ 119.99 a year, about half the price of twelve separate months. In Colombia, $ 44,900 and $ 269,900.

  • A 4x larger included-AI allowance: 800 tutor calls and 500 writing calls a month, against 200 and 120
  • And nothing else: Pro is capacity, not features

No screen, no statistical model, no report and no export will ever sit behind a paywall. Charging for the engine would turn "you can verify this" into "you can buy this", and charging to export an analysis you ran on your own data on your own machine only produces copy-paste.

Why that price

It is the most expensive of the three Somatryx apps, and not for positioning: it is the only one whose cost grows with usage. Every included-AI call costs real money, so an allowance four times larger has a real cost ceiling per subscriber per month. The price covers that ceiling; if it did not, the allowance would be a promise we would have to trim later.

The included AI

Eikos ships a methodological assistant with free monthly limits, at no cost and with no key on your side. To apply those limits the app creates an anonymous identifier the first time you use it; this is explained in the privacy policy. There is no paid subscription active today and no purchase button is shown on any platform.

External costs

If you prefer your own key, the remote provider you choose bills you at its own rate, and that is between you and them. Eikos does not cap that mode, now or ever. Any future pricing will be published here before it is switched on, not after.
