# Dori > Dori helps builders test products and web flows with synthetic customers, uncover UI/UX friction and turn findings into improvements before shipping. Dori provides pre-human validation and product taste for builders and their agents. It uses synthetic participants to explore products, UI/UX flows and customer-facing AI agents through browser-accessible interfaces. Synthetic findings are hypotheses to investigate. They do not replace human customer research, prove factual correctness or predict measured conversion rates. Examples in these guides are illustrative, not live customer test results. Test execution depends on current availability and account access. Refer to the public website and your account for current availability and pricing. ## Testing guides - [Synthetic customer testing](https://trydori.io/synthetic-customer-testing.md): Synthetic customer testing uses AI participants to explore a product from different customer perspectives. Dori helps builders find confusion, friction and trust issues before sharing a product with real users. - [Onboarding testing](https://trydori.io/onboarding-testing.md): Onboarding testing examines whether a new user can move from arrival to a first useful result. Dori uses synthetic participants to explore signup and setup flows, showing where instructions, decisions or interface states may create friction. - [AI agent testing](https://trydori.io/ai-agent-testing.md): Dori helps builders examine customer-facing AI agents through a browser-accessible interface. Synthetic participants can explore whether a chat or agent experience understands their goal, explains its actions and helps them recover when an interaction goes wrong. ## Product information - [Dori homepage](https://trydori.io/): Product overview and current plans. - [Founders](https://trydori.io/founders): Meet the team and get in touch. - [Blogs and socials](https://trydori.io/blogs-socials): Product updates, builder stories, and community perspectives. - [For agents](https://trydori.io/for-agents): Read or download the website as plain text. - [Complete website text](https://trydori.io/llms-full.txt): Every homepage section, interactive example, prices in GBP and USD, founders, social updates, all guides, contact details, website privacy policy, and website terms in one UTF-8 text file. ## Optional - [Website privacy policy](https://trydori.io/privacy.html): The marketing website and earlier demo or early-access requests. - [Website terms](https://trydori.io/terms.html): Terms for the marketing website and public guides. - [Privacy policy](https://trydori.io/privacy): How account, workspace and test data are handled. - [Terms of service](https://trydori.io/terms): Terms for using Dori. - [Sitemap](https://trydori.io/sitemap.xml): Canonical public website pages.
