Contact SentientUI

We're a developer-first team building adaptive UI personalization for the web — SentientUI learns what each visitor persona wants and serves the interface most likely to convert them. Whether you're evaluating it, already integrating it, or reporting something broken, the fastest ways to reach us are below.

Every route here reaches a human. We reply within one business day on support and sales, and we'd rather answer a specific question about your stack than send you a deck.

Send us a message

Support, sales, or a developer question — we reply within one business day. It helps to include the site you're installing on, whether you're using the no-code snippet or the React SDK, and what you expected to happen.

Support & sales

Email hello@sentient-ui.com for help with your account, billing, or a demo. We reply within one business day. If you're comparing plans, tell us your monthly sessions and we'll tell you which tier fits rather than guessing upward.

Developer docs

Setup, SDK, and API reference live in the documentation. The public API spec is at /openapi.json, and integrations covers Webflow, WordPress, and Framer step by step.

AI assistants (MCP)

Connect Claude, ChatGPT, Cursor, or Codex to your project data at https://api.sentient-ui.com/mcp. See the MCP guide. Assistants can read your stats and briefs directly, so you can ask questions about a project without opening the dashboard.

Packages

@sentientui/react, @sentientui/mcp, and @sentientui/cli on npm. Bug reports and pull requests are welcome on GitHub.

Security reports

Found a vulnerability? Email hello@sentient-ui.com rather than opening a public issue. Include reproduction steps and the affected package or endpoint. You'll get an acknowledgement within a few business days, and we'll coordinate a disclosure timeline with you.

Privacy & data protection

SentientUI is first-party only — no fingerprinting, no cross-site tracking. Our privacy policy lists everything collected, and the data processing agreement covers you as a controller. Data protection requests go to dpo@sentient-ui.com.

Before you write in

A few things people ask often enough that the answer is already published. The live demo shows adaptation happening rather than describing it. Pricing is session-based, with a free tier to start. Onboarding currently runs through the Design Cohort — self-serve signup opens after cohort one. And the changelog is the honest record of what shipped and when.

Where we are

SentientUI is based in London, E14 9BE, United Kingdom, and we work with teams worldwide. We're remote-first, so email and the form above beat post for anything that needs an answer this week.
