THE PREVIEW, PLAINLY
A clear view of
what comes next.
Pytrel AI is a new branch of Pytrel Systems. This public experience introduces the direction—and makes the current boundary explicit.
Keep it honest
No live AI, uploaded material, project action or account entitlement is operating here.
A FEW USEFUL ANSWERS
Good questions. Clear answers.
Am I talking to live AI?
No. Every question and response shown here is an authored, synthetic example. Choosing a card changes the demonstration on your screen; it does not call a model.
Can I upload a drawing or use my Takeoff project?
Not in this preview. There is no upload or document-processing connection. This site does not carry Takeoff projects, account sessions, sources or authorization into Park or Keystone.
What are Nexus and Keystone?
Nexus is Pytrel’s planned construction-intelligence platform and future agent, model and API access universe. Keystone is a flagship intelligence family within it. These names describe the product direction, not a released foundation model.
Is Park the same as Keystone Free?
No. Park is intended as an always-free playground to evaluate Pytrel intelligence, including its future API direction. Keystone Free is a separate planned workspace tier. Live usage and plan allowances are not activated by this preview.
Does interacting with this page train a model?
No. This preview has no live prompt submission or feedback intake and does not train a model. Any future improvement or research program would require its own disclosed rights and consent process.
Can I purchase API access or a paid plan?
Not yet. The Memberships page shows the planned Keystone lineup, not an active offer. When purchasing opens, checkout will stay on pytrel.com. This preview has no checkout, account connection, trial, usage balance or API key generation. API access is a separate future service.
Does choosing a division or a model level activate anything?
No. Division selection focuses the authored examples without saving an account profile. Keystone is the model family, Quick and Detailed are display preferences, and Free, Basic, Plus and Pro are planned memberships—not separate released models. A selection does not establish technical coverage or grant access.
How is the free usage flow intended to work?
The planned Keystone flow starts with a limited guest allowance, requires an account for a further Free allowance, then pauses new usage for 72 hours after that allowance is used unless the account upgrades. Limits would be visible and checked before the next task, with admitted work allowed to finish. Exact allowances are not set, and this static site does not count usage, create accounts or run a cooldown.
What can I use the example artifacts for?
They illustrate structure and review discipline. They are synthetic drafts, not a technical approval, product selection, code conclusion, project instruction or substitute for review of the actual controlling sources.
Open the frame. Protect the work.
Name the uncertainty. Keep the decision with the human.
