Conversion tests with commentary, not just numbers
Funnel reports, A/B test readouts, and conversion movement explained — without becoming the analyst on the team.
The experiment readout treadmill
Your week, before and after
- A/B test readouts written from scratch every test.
- Segment analysis as a CSV-export-and-pivot exercise.
- Experiment memory in a spreadsheet someone owns but nobody reads.
- Funnel issues discovered by anomaly, not by alert.
- ✓Test readouts drafted automatically with segment-level commentary.
- ✓Funnel reports that highlight where drop-offs are getting worse.
- ✓Memory across experiments — what we tested, what we learned, what to retest.
- ✓Anomaly alerts on conversion movement, not after-the-fact reports.
Conversion analysis that doesn't take a full sprint
A/B test readouts
Variant performance, statistical significance, and segment-level commentary — drafted from the experiment tool and joined with revenue data.
Funnel reports
Step-by-step conversion with period comparisons. Where the drop-off is, how it changed, and what segment is most affected.
Segment performance
Don't just report aggregate conversion — break out by traffic source, device, audience, or any segment that matters.
AI commentary on the why
Why this test won, why that segment underperformed, what to try next — written from the data, not the gut.
Experiment memory
Past tests, hypotheses, and outcomes stay in the semantic layer. Next quarter you don't retest what you already learned.
Anomaly detection on conversion
When a funnel step suddenly converts 30% worse, Chartcastr flags it the day it happens.
An A/B test readout with Chartcastr
Headline result
Variant B lifted checkout conversion by 8.3% with 95% confidence. Estimated revenue impact: $42k/month.
Segment breakdown
Lift concentrated in mobile users; desktop was flat. New users +12%; returning users +3%.
Why it likely won
AI commentary on the most plausible drivers, based on the segments that moved.
Suggested follow-ups
Tests to run next based on what this experiment surfaced.
Frequently asked questions
Which A/B testing tools do you support?
Chartcastr reads from your analytics layer (GA4, Mixpanel, Amplitude, PostHog) and joins it with your experimentation platform. If you store variant assignments in your analytics, we can read them.
Do you compute statistical significance?
We surface what your experimentation tool reports and add commentary on segment-level patterns. If you want Chartcastr to compute stat-sig from raw data, that's possible with a warehouse connection.
Can I get a Slack alert when a funnel step degrades?
Yes. Set thresholds (or let anomaly detection set them automatically). When a step breaks its normal range, the channel you choose gets a pulse with the diagnosis.
Does this work for SaaS funnels, not just e-commerce?
Yes. Any sequence of steps — landing, signup, activation, paid conversion, retention — can be modeled as a funnel. SaaS and product-led growth teams use this for activation and conversion reporting.
