Sizzle, founded in 2023, points a phone camera or shares a screen the way several homework-help tools in this category do, but leans specifically into voice-based tutoring conversation afterward, talking through a STEM problem's reasoning out loud rather than only displaying a static, text-based step-by-step solution.
That conversational, voice-first format aims to more closely simulate what an actual tutor sitting beside a student would do, asking follow-up questions and adjusting an explanation based on where a student seems confused, rather than presenting one fixed explanation regardless of whether it actually clarified anything.
Sizzle is free to use. For a student who wants a back-and-forth, spoken conversation about a STEM problem rather than a single static text explanation, Sizzle's voice-first tutoring format is built specifically for that more interactive, adaptive style of help.
