How It Works
No SDK, no tracking code, no engineer. You bring a file you can already export today, and Clu does the arithmetic, shows its working, and tells you where it cannot help.
Add data
No SDK, no tracking code, no engineer.
Understand
You see the file described before you trust anything built on it.
Match
Whatever you leave untouched becomes a recorded assumption, not a silent guess.
Analyze
A few seconds to a minute.
Results
Findings ranked by what each one cost you in sessions. Every finding carries its numerator, denominator and window, the evidence underneath it, a confidence level with the rule printed below it, the explanations worth considering — and the ones the data does not support. Read it here, correct something and run it again.
BEFORE YOU ASK
The short answers.
Which files work?
CSV, TSV or Excel, up to 24 MB. Session-level or event-level. A GA4 BigQuery export is reshaped for you.
Do I need an engineer?
No. If you can export a file, you can run Clu.
What happens to my upload?
Deleted within two days. Never used for training. On Plus you download it and it stays with you.
Can I ask my own question?
Yes. One free-form question over a run, and the diagnosis marks the observations that answer it — or says that none do.
Stop guessing why people leave.
Upload the export you already have. Read the diagnosis. Decide what to test.
