Windsor.ai and Causality Engine, fact by fact
Competitor pricing is each vendor's publicly listed pricing as read on the date shown, and it changes without notice: verify on the vendor's own site before relying on it. Vendors without a public price are marked as such. Comparisons set Causality Engine's one-time €99 analysis against subscription models.
How to switch, in five steps.
No cancellation required yet
Keep Windsor.ai running (its terms: monthly or annual (annual paid upfront)). Causality Engine reads your GA4 CSV export, so nothing conflicts and no data moves between the two.
Upload your GA4 CSV (no integration required)
Export 12 months or more of GA4 data and upload it. Longer reads better. No OAuth, no pixel, no code, no DNS changes. Shopify native is on the roadmap.
Run your first analysis
What each channel caused, next to last-click, with a data-health score on each, 1 to 2 minutes after the upload. Compare it with what Windsor.ai was telling you.
Evaluate side by side
Run both for a month and compare them channel by channel. Where they disagree is where a budget decision is at stake.
Cancel Windsor.ai when ready
Only if the side-by-side says you should. On refunds, Windsor.ai states: no refunds; all sales are final. Nothing in Causality Engine depends on Windsor.ai being gone.
What to weigh before you leave Windsor.ai
Windsor.ai uses rules-based and data-driven MTA and is best for small businesses wanting affordable MTA with data connectors. Where it differs from a causal read:
- Low-cost tier is severely limited
- Rules-based models are subjective
- No causal inference methodology
- Accuracy degrades with iOS privacy changes

Yes. Causality Engine installs nothing on your site. It reads the GA4 export you already have, so it runs on top of any tool here without touching its setup. The one condition: GA4 runs on your store too.
