Fair questions.

Yes. Semantix v1 is free, including commercial use — build and ship paid work with it from day one. It's not a trial and nothing expires. Paid tiers arrive later, for the cloud features that cost us real money to run.

You connect your own model provider keys (Anthropic, OpenAI, or a local model) and pay them directly for tokens — Semantix doesn't resell AI usage or mark it up. For exactly what leaves your machine and when, the Privacy Policy says it plainly.

When the cloud does. The prices on this page are previews, not promises — final numbers land with the release. Signing up now gets you Spark today and a place in line for the rest.

Your code, your graph, and your local memory live on your disk — they were never ours to hold. Losing a paid tier means losing the cloud conveniences, not your work.

We like both. Nothing formal yet — write to us and we'll figure it out like people.

Start with Spark. It's most of the light.
