    We grade how students actually express knowledge

    Most platforms can check a multiple-choice bubble. Ours grades the full range of how you really demonstrate understanding — spoken answers, typed free-response and essays, handwritten math photographed mid-problem, and multi-step solutions evaluated one step at a time. Feedback is specific and rubric-aware: the AI derives criteria from your source material (or a rubric you define) and tells you exactly where your reasoning broke down, not just that an answer was wrong.

    Four ways to be graded

    Spoken answers

    Speak aloud and the AI grades accuracy, completeness, depth, and confidence in real time — the engine behind FastFire, available in any mode.

    Typed & essay responses

    Free-response and essay answers graded against rubric criteria the AI derives from your materials. Specific feedback, never generic.

    Handwritten work

    Photograph worked math, a diagram, or a science setup. The AI reads it, evaluates each step, and pinpoints where the error occurred.

    Multi-step solutions

    For math, chemistry, physics, and logic — every step is graded independently so you see exactly where the reasoning broke.

    Get graded on more than bubbles

    Speak, type, or photograph your work — and get step-by-step feedback that finds the exact break point.
