Test. Learn. Repeat.LeLoop tests your signup popups for you. A small group of visitors never sees a popup, so LeLoop measures the sales your popups add, not just the signups. From $29 a month. How we measure →
Not on Shopify? LeLoop works on any website: Squarespace, Wix, Webflow, WordPress. Add it to yours →
A 40-second tour. The results in it are simulated.
Most popup tools are configured once and left alone. LeLoop doesn't stop working after setup.
AI continuously tests every offer and shifts traffic toward whichever one is actually converting — not a fixed split that runs forever either way.
Learn more →Popups fire at the moment a visitor is actually likely to convert — exit intent, scroll depth, time on page — not a blind timer.
Learn more →Flip on auto-pilot and LeLoop locks in the winner the moment it's statistically confident — no dashboard check-ins required. Every decision it makes is logged in plain English, so you always know what ran and why.
Learn more →LeLoop reads its own statistics and turns them into plain-English recommendations with one-click actions. Every insight traces back to a number on your analytics page. No black box.
LeLoop runs continuous experiments in the background using Thompson Sampling — a statistical method that shifts traffic toward the winning offer as evidence builds, instead of a flat 50/50 split that never adapts.
Target by page, traffic source, device, new vs. returning visitor, engagement, and exit intent — and let the AI learn a separate winner for each segment, so mobile shoppers and desktop shoppers each see what works for them.
Pick from ready-made offers — a discount, a free-shipping nudge, a VIP early-access pitch, a spin-to-win wheel — each with two versions already written and ready to test. Edit the copy or launch as-is; either way you're live in under a minute.
Turn a popup into a prize wheel: shoppers enter their email, spin, and every slice wins something — a percentage off or free shipping. On Shopify each winner gets their own single-use code; on any other website, the code you set for that prize. LeLoop decides where the wheel stops, never the shopper's browser, and can test the wheel against a classic "10% off" so you see which one your visitors actually sign up for.
Most testing tools stop at "here's a recommendation" and wait for you to act on it. LeLoop can go one step further: turn on auto-pilot and it locks in the winner itself once it's ≥95% confident, so the losing versions stop showing automatically. Every autonomous decision — and every manual one — lands in a running activity log, so nothing happens in a black box.
| LeLoop | Typical email tool | Basic popup app | |
|---|---|---|---|
| Optimization | Continuous, automatic — shifts traffic to the winner as data comes in | Manual A/B tests, someone has to check and turn off the loser | Fixed split, runs forever regardless of results |
| Triggering | Behavior-based: exit intent, scroll depth, time on page | Basic timer, same for every visitor | Basic timer, same for every visitor |
| Targeting | Page, traffic source, device, new vs. returning, engagement score, exit intent | Page-level only | Page-level only |
| Personalization | Learns a separate winner per device and/or visitor type — and won't flatten it | One winner for everyone | One winner for everyone |
| Offers | Smart Offers: a discount range, sized per visitor by how close they are to leaving | One fixed code | One fixed code |
| Spin to win | A prize wheel where every slice wins, tested against a classic offer to see which signs up more | Usually a plain form | A wheel you pick and leave running |
| Goal | Optimize for email signups or for purchases — the version that sells, not just the one that collects | Opt-ins only | Opt-ins only |
| Scheduling | Start/end windows per campaign, auto-lock per audience segment, plain-English AI Insights | Manual | Manual |
| Proves real sales | Compares against a no-popup group, on by default | Counts signups, or credits the last popup seen | Counts signups, or credits the last popup seen |
| Price | From $29/month | — | — |
| Reporting | Win probability, signups, and attributed revenue per version, plus AI Insights | Opt-in rate and submits only | Impressions and clicks only |
On Shopify, LeLoop is an app you switch on. Anywhere else, it's one line in your site's header. The AI testing works the same on both.
Install from Shopify, then switch it on in your theme editor. No code.
Sign up with your site's address, paste one line into its header, and LeLoop checks it's there.
Free while LeLoop is in beta. Not there yet off Shopify: one-time codes (write your code into the popup instead), the "earned you $X" number, and the Shopify-only extras (cart-value rules, Smart Offers, image uploads).
An AI that changes what your customers see should be able to explain itself. LeLoop is engineered around that. How we measure results → · Security →
Thompson Sampling decides what each visitor sees; a 4,000-draw Monte Carlo estimate says how sure it is. Auto-pilot won't act below 95% confidence or 200 visits, and won't collapse a popup whose segments want different winners.
Auto-locks, manual locks, and resumed tests land in a durable activity log in plain English. AI Insights link straight to the numbers behind them.
600+ automated tests, including an integration suite that runs the real API against real Postgres on every change. Shopify's own sign-in with one-minute tokens, store-scoped access, rate limits.
