Built by Developers Who Were Tired of Support Tickets 🤯

We've all been there. You ship a feature, and immediately get flooded with "I don't understand" emails. Users clicking the wrong buttons. Users who can't find the obvious "Save" button. Users who... shouldn't be users.

So we built IQaptcha to solve this once and for all. Now you can know exactly who you're dealing with before they even touch your app.

We created IQaptcha for 3 reasons:

  1. Reduce support burden—filter out users who won't understand your product anyway.
  2. Improve user experience—show simpler UIs to users who need them, advanced features to those who can handle them.
  3. Increase conversion rates—stop losing sales because your checkout is "too complicated" for some users.

Hundreds of developers are already using IQaptcha to build smarter applications that adapt to their users. No more one-size-fits-all. No more dumbing down for the lowest common denominator.

Your smart users will thank you. Your support team will thank you. Your stupid users? They won't even know. 🎯

Adding IQaptcha is simple: 1) Sign up at iqaptcha.com/dashboard, 2) Get your site key, 3) Add our JavaScript SDK to your page, 4) Include a div with class='iqaptcha' and your site key. Takes under 5 minutes to set up.
Yes! IQaptcha provides better user experience than reCAPTCHA's image puzzles. Instead of 'click all traffic lights', users solve engaging cognitive puzzles. You get bot protection PLUS user intelligence insights that reCAPTCHA doesn't provide.
Include our JavaScript SDK, add a div with your site key, then listen for completion events. The SDK provides tokens you can verify server-side. Works with any form - contact forms, signups, checkouts, comments.
IQaptcha eliminates the frustration of blurry image recognition. Users solve pattern puzzles that feel like games instead of annoying CAPTCHA challenges. 95% of users prefer our cognitive puzzles over traditional CAPTCHAs.
Absolutely. IQaptcha is a CAPTCHA system that happens to measure pattern recognition skills. We don't discriminate based on protected classes - we simply provide cognitive assessment data.
Based on our data: ~20% score below 85 (low average), ~60% score 85-115 (average), ~20% score above 115 (above average). Your mileage may vary depending on your audience.
Our pattern recognition tests correlate strongly with traditional IQ tests. While not a clinical assessment, they provide reliable cognitive ability indicators for user segmentation.
You don't have to block anyone. Use IQaptcha to adapt your UI - show simplified interfaces to lower scorers and advanced features to higher scorers. Everyone wins.
It's harder than you think. The tests are timed, randomized, and require genuine pattern recognition. Bots consistently fail, and humans can't easily game the system.
IQaptcha tests visual pattern recognition only. For users with visual impairments, you should provide alternative verification methods as with any CAPTCHA system.
No! IQaptcha works entirely through client-side postMessage events. You can also use webhooks for server-side validation if preferred.
Regular CAPTCHAs just verify you're human. IQaptcha verifies you're human AND measures cognitive ability, giving you actionable user intelligence data.
Yes! Set any IQ score as your threshold. Default is 100 (average), but you can require 85 for basic access or 115 for advanced features.
Yes! The free tier includes unlimited IQaptchas and basic analytics. We'll add paid tiers with advanced features based on demand.
IQaptcha is the easiest CAPTCHA to add. Just include our JavaScript SDK and add a div with your site key. Works with any website, framework, or CMS. Setup takes under 5 minutes.
IQaptcha integrates perfectly with React using our JavaScript SDK. Create a reusable component that handles CAPTCHA completion events. Much easier than reCAPTCHA integration.
Add IQaptcha to WordPress without plugins. Include our SDK script, add the CAPTCHA div to your forms, and verify tokens in functions.php. Works with Contact Form 7, Gravity Forms, and custom forms.
IQaptcha is perfect for e-commerce checkout and registration forms. Users complete it faster than reCAPTCHA, reducing cart abandonment. Plus you learn about customer intelligence levels.
Include IQaptcha's JavaScript SDK, add a div with your site key to the form, then listen for completion events. Works with any contact form system and provides better user experience than traditional CAPTCHAs.
IQaptcha's cognitive puzzles work much better on mobile than reCAPTCHA's tiny image tiles. Touch-optimized interface with 95% first-try completion rate vs reCAPTCHA's 67%.
Use IQaptcha tokens to rate-limit API access based on user intelligence. High-IQ users get higher rate limits, while suspicious traffic gets restricted. More nuanced than simple bot blocking.
IQaptcha integrates seamlessly with Next.js. Add the SDK to _document.js or load dynamically, use our completion events in your components, and verify tokens in API routes. Full TypeScript support available.
IQaptcha is the easiest migration. Replace Google's script with ours, change 'g-recaptcha' to 'iqaptcha' class, and listen for our completion events instead of callbacks. Takes 10-15 minutes total.
IQaptcha provides the best registration experience. Users enjoy the cognitive puzzles instead of struggling with unclear images. Plus you get user intelligence data to better understand your new signups.

What Developers Are Saying

Real feedback from real developers who are already filtering

BA

Blake Anderson

CTO @ TechFlow

Our support tickets dropped by 73% after implementing IQaptcha. We now show a simplified checkout to low-score users and our conversion rate actually went UP!

SD

Sage Davis

Product Lead

Finally, a way to segment users without asking invasive questions. Our power users get advanced features, everyone else gets the basics. Perfect.

IQaptcha is ethically questionable and absolutely brilliant. My documentation site now adapts complexity based on cognitive scores. Genius.

ST

Sage Taylor

Founder @ DataSync

We use it for our SaaS onboarding. Low scores get a guided tour, high scores skip straight to advanced settings. Customer satisfaction is through the roof.

SJ

Sage Johnson

Growth Hacker

Integrated IQaptcha last week and already filtered out 200+ users who would've just confused themselves and churned anyway. Worth every penny.

TM

Taylor Moore

Indie Game Dev

As a game dev, matchmaking by cognitive ability is a game-changer. Players finally get fair matches and rage-quitting dropped 60%.

QA

Quinn Anderson

EdTech Founder

Our e-learning platform uses IQaptcha to automatically adjust course difficulty. Student completion rates increased by 40%!

BM

Blake Moore

SaaS Founder

Controversial? Maybe. Effective? Absolutely. My customer support team loves me now. No more explaining what a 'button' is.

BT

Blake Taylor

Growth @ StartupXYZ

We A/B tested it. Users who scored >70 saw our pro features. Pro plan conversions went up 85%. This thing pays for itself.
