Hi HN, we're Mayank and Matt of Roundtable (https://www.roundtable.ai). We launched our Survey Simulator as part of YC S23 (see Launch HN: https://news.ycombinator.com/item?id=36865625), and ultimately decided to pivot because we couldn't convince users to trust our results and our value proposition wasn't clear.

We conducted tons of user discovery interviews, and a lot of big players talked about the pain of manual QC and bot detection. We launched a survey fraud and bot detection API (Alias; docs.roundtable.ai) that determines whether a bot is answering your survey or not. Our API embeds Javascript into survey programs (Forsta, Qualtrics, jsPsych, etc.) to track user behavior and make a judgment on whether the data is from a high-quality participant.

You can use our demo, and try to break it, here: https://www.roundtable.ai/hn-demo. See if you can generate LLM-based text without any flags going off! Feedback welcome!
