Socratic, acquired by Google in 2018, lets a student photograph a homework question across a wide range of subjects, science, literature, history, math, and get an explanation drawing on curated educational content and step-by-step reasoning, one of Google's earlier moves into AI-assisted homework help well before Gemini and LearnLM, also covered in this directory, existed.
That broad subject range, rather than a narrower math-only focus, was Socratic's original point of difference from more specialized competitors, but Google's more recent education investment has shifted toward Gemini's own Learn Your Way and Guided Learning features, built on LearnLM, rather than continued heavy development on Socratic specifically.
Socratic remains free to use. For a student who wants broad-subject camera-based homework help specifically, Socratic still functions, though anyone comparing it against Google's newer Gemini-based education tools should factor in that Google's current education AI investment centers on those newer features rather than Socratic's original app.
