Fractl Research

Original research on how AI actually decides what to recommend

The tools inside Fractl Agents are built on measurements, not vibes — and we publish the measurements. Every piece here ships with its data files, its pre-registrations, and its full corrections log, because we'd rather you checked us than believed us.

What AI actually recommends

We measured every brand and every source in 11,573 AI answers across 15 industries, then joined it to what's inside the models' training data. Which sites AI trusts, why 73% of what it cites doesn't rank on Google's page one, how new brands win on live visibility instead of fame, and why getting featured on the sites AI cites — earned media — just became how you win an AI recommendation.

Can you actually make AI writing undetectable?

We built the detector ourselves, ran a census of 326 models, and trained our own rewriters on rented GPUs. Detecting AI writing is basically solved and the "sound more human" checklists are a myth — but the one-click "humanizer" promise runs into a real wall: you can evade detection, or keep the facts, not both. A field report on what's solved, what's snake oil, and why.

Where AI recommendations actually come from

We read a real AI model's actual training data — the only model on earth where that's possible — and ran 6,000+ controlled retrieval experiments across nine models, including a company we invented. What memory buys, what a retrieved page buys, why mention-count "AI visibility" scores measure the English language, and why the newest models are becoming auditors that discount promotional content.
