FastSolve routes your STEM exams to Gemini Flash—and keeps your question logs forever.
Before you pay $9.99/week ($39.96/mo) for FastSolve, read what their own docs admit: (1) even their “Invisible” mode forcibly auto-fills host LMS inputs (isTrusted: false); (2) math and science are routed to lightweight Gemini Flash for speed (admitting ALEKS multi-step math is “not perfect”); and (3) they retain your quiz questions and answers without automatic expiration.
ExamGhost runs full-reasoning Multi-Model STEM Consensus inside a zero-retention Closed Shadow DOM HUD—starting with 50 Free Solves ($0, no credit card).
“Every mode auto-fills the answer — they only differ in visual feedback.”
→ Mutates host DOM inputs (isTrusted: false) in every mode“Math and science route to Gemini Flash for speed... multi-step math on ALEKS is not perfect.”
“We retain solve diagnostics, including question content and answers, without automatic expiration.”
Inspect FastSolve's 3 Engineering Trade-Offs
Click each tab below to compare FastSolve's forced DOM auto-fill, its Gemini Flash math shortcut, and its permanent question retention against ExamGhost.
All 3 modes programmatically mutate your quiz inputs
FastSolve advertises three modes: Homework, Sneaky, and Invisible. Students select Invisible assuming the extension won't touch the exam page.
Yet FastSolve's own documentation admits: “Every mode auto-fills the answer — they only differ in visual feedback.” When you double-click, FastSolve programmatically selects radio buttons or mutates text fields (isTrusted: false), writes auth tokens to host localStorage, and fails to block window.blur when you open its popup.
View the answer silently—click it yourself with real hardware
ExamGhost never forces synthetic JavaScript auto-fill clicks onto your Canvas or ALEKS inputs. You choose between a subtle 1px Invisible Dot cue or a 0%–100% Opacity Closed Shadow DOM HUD, and click the answer yourself (`event.isTrusted: true`).
- Zero Host `localStorage` Tokens: All session state is sandboxed inside Chrome's encrypted extension storage.
- Focus Shield Active: Intercepts 100% of
window.blurandvisibilitychangeevents.
Sacrificing calculus & chemistry accuracy to save API costs
Under its Smart Model Routing breakdown, FastSolve explicitly admits: “Math and science route to Gemini Flash for speed.”
Lightweight Flash models are designed for cheap chat summarization—not multi-step university stoichiometry, organic chemistry, or calculus integrals. That's why FastSolve's own ALEKS FAQ warns students: “Multi-step math on ALEKS is not perfect; always read the worked solution before submitting.”
Verified symbolic math & Snap-It Vision OCR in 0.3s
ExamGhost never downgrades your STEM problems to a cheap Flash model. Every calculus, physics, chemistry, and statistics question is verified across our flagship multi-model STEM consensus pipeline—including locked diagrams snipped with ⌘+Shift+S.
- ALEKS, WebAssign & Pearson MyLab Ready: Handles multi-step symbolic algebra, significant figures, and LaTeX matrices accurately.
- Included on All 50 Free Solves: Test our full STEM accuracy before spending a dollar.
Why let an extension store your exam questions forever?
FastSolve's privacy policy contains a clause every college student should read twice: “We retain solve diagnostics, including question content and answers, without automatic expiration to investigate issues and improve reliability.”
Meanwhile, its free tier only allows 10 multiple-choice questions per day before pushing a $9.99/week ($39.96/month) or $19.99/month subscription where refunds are only granted case-by-case via email.
Zero stored exam questions. 50 Free Solves upfront.
ExamGhost processes every text and screenshot query in ephemeral memory and immediately purges the payload once your answer renders—leaving zero permanent database trail of your university exams.
What Your Professor Sees in SpeedGrader
Canvas automatically timestamps every time you click off the test window or trigger unshielded input mutations.

Frequently Asked Questions: FastSolve vs ExamGhost
Does FastSolve protect against Canvas tab-switch tracking or DOM mutation checks?
No. FastSolve (Chrome ID gpbmomndeioigacdailloflpngipnfgh, v3.3.15) does not intercept window.blur or document.visibilitychange events, and its documentation admits that all three modes (Homework, Sneaky, Invisible) forcibly auto-fill answers directly into the host LMS input DOM while storing auth tokens in browser localStorage.
Why does FastSolve struggle on multi-step ALEKS and college STEM problems?
FastSolve's Smart Model Routing explicitly routes math and science queries to lightweight Gemini Flash models for speed, and its own FAQ admits that multi-step math on ALEKS is 'not perfect; always read the worked solution before submitting.' ExamGhost uses full-reasoning multi-model STEM consensus.
Does FastSolve log and retain student quiz questions?
Yes. FastSolve's official privacy policy explicitly states that they 'retain solve diagnostics, including question content and answers, without automatic expiration to investigate issues and improve reliability.' ExamGhost operates a strict zero-retention ephemeral pipeline.
How does FastSolve pricing compare to ExamGhost in 2026?
FastSolve offers 10 free multiple-choice solves per day, then charges $9.99/week ($39.96/mo), $19.99/month, $49/semester, or $99/year with refunds handled only case-by-case via email. ExamGhost gives you 50 Free Solves upfront (no card required), plus transparent options: $19/mo, $99/yr ($8.25/mo), or $199 Lifetime.
Speed without stealth or STEM accuracy is a trap.
