ESAI
ESAI helps students find what actually distinguishes them — their patterns, values and formative moments — and shape it for college applications, internships and first jobs. Brandi, a voice agent, talks it out with them, and the platform was designed by former college advisors and admissions officers.
- Coaches the student to write rather than writing for them, and says so
- Voice is the right modality — teenagers talk about themselves better than they write
- Former admissions officers is the credential that actually matters here
- Specificity, which coaching produces, is what admissions readers reward
- The savings figure rests on unstated assumptions about counselling take-up
- Universities accepting applicants measures where users applied, not product effect
- The individual advisors behind the design are not named
