Why WebWork answer keys don't exist
WeBWorK is an open-source online homework system, developed in association with the Mathematical Association of America and used by university math departments for calculus, linear algebra, differential equations, and statistics problem sets. Its defining feature is seed-based randomization: each student's copy of a problem is generated with different numbers, so your "find the derivative at x = 3" is someone else's "at x = 7". That single design choice is why searching for webwork answers turns up nothing usable — any posted answer key was worked from a different version of the problem.
Chegg and Course Hero uploads, Reddit threads, and shared PDFs all hit the same wall: the setup matches, the final answer doesn't. At best a posted solution shows you the method, and you still have to redo the arithmetic with your own values. An AI solver flips the approach — instead of looking your problem up, FastSolve works the exact problem on your screen, with your numbers, and shows the steps.
The paste-and-screenshot workflow on WeBWorK
FastSolve has no native WeBWorK adapter today, so it never touches the WeBWorK page — no detection, no auto-fill, no injected overlay. The workflow is manual by design: copy the problem text, or capture a screenshot when the notation is heavy, and FastSolve returns the worked answer in about 2 seconds. The vision flow reads the capture whole — the problem statement, any graph or figure, and the answer blanks — so multi-part problems come back with each part addressed.
Entering the answer is on you, and WeBWorK is picky about syntax. The worked steps give you the exact value — keep fractions exact where the problem demands them, add parentheses generously, and use WeBWorK's Preview button to confirm your entry parsed the way you meant before you submit. Most sets allow multiple attempts, so a syntax slip costs an attempt, not the assignment.
Native WeBWorK support: where it sits on the roadmap
FastSolve ships native in-page adapters for Canvas, Blackboard, Moodle, Brightspace, ALEKS, Schoology, Knewton, Learnosity, and DeltaMath — on those platforms the extension detects the question in the page and fills the answer directly. WeBWorK doesn't have a native adapter yet, so this page describes the paste and screenshot workflow honestly rather than pretending otherwise.
Native WeBWorK support is on the FastSolve roadmap. Until it ships, the paste and screenshot flow covers WeBWorK problem sets — including graph and figure problems — with the same solving engine, powered by Claude and GPT-4o, that the native platforms use.
