# GAIvsIQ Review Free browser-based IQ estimate across nine cognitive tasks, with a $19.99 one-time detailed report, and no account required. ## Editor's Score: 66/100 Ease of use is the clear strength: no account, no install, mobile-friendly, pause-and-resume by task, and a public sample report before any purchase decision. Value is solid given the free FSIQ and GAI result and a one-time $19.99 report with no subscription trap. Capability is limited by the absence of age norming, no reliability data, and domain scores locked behind the paywall, which means the free output is thinner than the nine-task structure suggests. Delivery takes the biggest hit: no third-party user sentiment was findable, no reliability coefficient is published for the estimate, and the tool's own site acknowledges the output cannot be used for any consequential decision, which is honest but also a real ceiling on what the product actually delivers for most people who seek an IQ test. ## Pros - Genuinely free core result: FSIQ, GAI, and the gap score require no account, no email, and no payment. - Transparent about limitations: the site explicitly states there is no reliability coefficient, no age norming, and no clinical validity, which is uncommon among consumer IQ products. - GAI gap score is a real differentiator: separating reasoning ability from working memory and processing speed is a clinically meaningful distinction that most free IQ tests do not attempt. ## Cons - Domain scores and the full cognitive profile are paywalled at $19.99, so the free result is a summary, not the complete picture the nine-task structure implies. - No reliability data or standard error is published for the nine-task estimate, meaning there is no way to know how consistent the score would be across two sittings on the same day. - Progress is saved only in the current browser session; switching devices or clearing cookies mid-test means starting over, since there is no account to sync state across. ## Pricing Freemium.

The free result covers Full Scale IQ and GAI, but domain scores and the full cognitive profile sit behind a $19.99 one-time paywall, which is fair pricing but worth knowing upfront. Anyone needing age-normed, clinically defensible scores for a school, employer, or visa application should stop here and go straight to a licensed psychologist. Best for: Curious adults wanting a free, no-signup IQ estimate with honest caveats Not for: Anyone needing clinically valid, age-normed scores for school, employment, or legal purposes ## Overview GAIvsIQ is a browser-based cognitive assessment that runs nine tasks covering five CHC domains and produces two composites: Full Scale IQ (FSIQ) and the General Ability Index (GAI), plus the gap between them. The gap score is the site's actual differentiator. Most free IQ tests give you a single number; this one is built around the clinically meaningful difference between reasoning ability and the drag of working memory and processing speed, which is the same distinction a neuropsychologist pulls from a Wechsler report. The test takes about 30 minutes across nine tasks, runs entirely in the browser, and saves progress by task so you can pause and return. No account, no email, no install. The free result shows FSIQ, GAI, and the gap. The $19.99 one-time report adds domain scores, individual task scores, and the full cognitive profile. The site also includes a separate GAI calculator for people who already have an official Wechsler report and just want the composites subtracted and interpreted. The site is unusually candid about what the numbers are not. The IQ score chart page states plainly that the percentiles describe a normal curve, not a normed sample, and that there is no reliability coefficient or standard error on the sheet because those figures would be invented. That level of transparency is rare among consumer IQ sites, most of which present their output as equivalent to clinical testing. GAIvsIQ does not claim that, and it says so repeatedly. ## Who should use it Adults who are curious about their cognitive profile and want more structure than a casual online quiz, but are not in a position to pay for formal neuropsychological testing, will get real value here. The free FSIQ and GAI scores, combined with the gap interpretation, give a meaningful starting point for self-understanding. Parents who have received a child's WISC or WAIS report and want help reading the GAI versus Full Scale IQ difference will also find the standalone calculator useful without needing to take the full test. Anyone who needs scores that a school district, employer, immigration authority, or clinician will actually accept should look elsewhere entirely. GAIvsIQ says this itself, clearly. For that use case, there is no online substitute for a licensed examiner using a publisher-normed instrument. Within this directory, EveryTool4U covers a broad range of free browser-based productivity utilities and may suit users who arrived here looking for general self-assessment or productivity tools rather than a structured cognitive test specifically. ## FAQ Q: Is the IQ score from GAIvsIQ valid for school placement or a clinical diagnosis? A: No. The site states explicitly that the nine-task estimate is not age-normed, has no reliability coefficient, and cannot be used by a school, clinic, employer, or visa authority. A licensed examiner using a publisher-normed instrument is required for those purposes. Q: What does the free result actually include? A: After all nine tasks, the free result shows your Full Scale IQ estimate, your GAI, and the gap between the two. Domain scores and task-level scores require the $19.99 detailed report. Q: How much does the detailed report cost, and is it a subscription? A: The detailed report is a one-time purchase of $19.99. There is no subscription. The report is saved to the checkout email so you can open it again later. Q: Can I take the test on a phone? A: Yes. The test runs in the browser and is phone-friendly. No app install is needed, and you can pause after any task and return in the same browser. Q: What happens if I switch devices or clear my browser mid-test? A: Progress is stored in the current browser session only. Without an account, switching devices or clearing cookies means you would need to restart the test from the beginning. Q: What is the GAI calculator, and who is it for? A: The GAI calculator is a separate tool for people who already have an official Wechsler report. It subtracts and interprets the GAI and Full Scale IQ composites from that report; it does not re-score a Wechsler and does not require taking the nine-task test.
