Dottya's answer:

High school and university students who want to understand their material, prepare for exams and write assignments with reliable sources, especially Spanish and English speakers.

StudyReach's answer

StudyReach was born in France in 2026 from a simple observation: recruiting participants for a study takes weeks (word of mouth, mailing lists, foreign panels). So a solo founder built a marketplace where researchers publish their study, the right profiles come to take part, and every participant is paid securely.

StudyReach est née en France en 2026, d'un constat simple : recruter des participants pour une étude prend des semaines (bouche-à-oreille, mailing lists, panels étrangers). Un fondateur solo a donc créé une marketplace où le chercheur publie son étude, où les bons profils viennent participer, et où chaque participant est payé en toute sécurité.

Dottya's answer:

Dottya was built by a solo maker in Colombia. Students were already using AI to study, but often couldn't tell whether an answer was right or where it came from. Dottya started as an assistant that always shows its sources, and grew into a full study companion that works with your own notes, quizzes you and helps you get ready for your exams.
