AI popup builder that adapts to every page in real time.

Don't pick from 50 templates. The AI reads each landing page, blog post, and product, and writes a unique headline that matches what the visitor is actually looking at — automatically, on every page, with no setup per URL.

Template galleries lost the war to language models.

A popup with a generic 'Get 10% off!' headline converts 1-2%. A popup whose headline echoes the article the visitor just read — "liked our take on Q4 ad strategy? Get the rest of the playbook" — converts 4-7%. Writing that headline by hand for every page on your site is impossible. The AI does it on every show, fresh. Reads the H1 + first paragraph + page intent, writes a matching popup headline, and runs A/B tests against 4 other angles to find what actually moves the needle.

Common questions.

Which AI model writes the copy?

We use a mix — primary headlines are generated by a modern LLM (currently Claude/GPT-class via OpenRouter); behavioral predictions come from our own ExitSense XGBoost model trained on 1M+ session signals. Both are managed by us — no API keys to bring, no usage bills.

How do you prevent the AI from saying something stupid?

Three guardrails: (1) a brand-voice instruction you set once that's prepended to every generation, (2) a banned-words list (e.g. 'unlock', 'revolutionize', 'game-changer' — turn them off and they never appear), (3) human-quality review of the first 5 generations before promotion. You can lock in the manual variant as fallback any time.
