Viewpoints AI

Viewpoints AI (viewpoints.ai) is a Stanford-founded research platform that runs AI jury simulations for litigation teams and AI audience panels for market researchers. Companies upload case materials or creative/marketing stimuli and a representative panel of simulated personas reads them, deliberates, and returns verdict or response distributions, the themes driving them, and per-participant reasoning — same-day, with a claimed 88% match to real studies (Stanford-validated). The Viewpoints Study API lets developers programmatically create studies, upload stimuli, poll asynchronous creation jobs, retrieve full participant results, and schedule recurring runs. SOC 2 Type II. Backed by Forerunner Ventures.

Viewpoints AI publishes 3 APIs on the APIs.io network: Studies API, Study File Uploads API, and Study Schedules API. Tagged areas include Company, Artificial Intelligence, Market Research, Synthetic Personas, and Consumer Insights.

Viewpoints AI’s developer surface includes documentation, API reference, authentication, and 17 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/viewpoints-ai: open an issue to ask a question, or submit a pull request to add artifacts.
