A free, browser-only workspace for performance marketers. Upload a campaign CSV or connect Google Sheets to diagnose performance shifts, budget headroom, creative fatigue, experiments, and marketing response(MMM,Regression Model and Cannibalization check)—without sending raw data to a server.
Hi, I’m the maker of Growth Opt Playbook.
I built this because performance marketers often have the data, but not a fast, trustworthy way to answer the next decision:
Why did performance move this week?
Which channel still has room to scale?
Is a creative getting fatigued?
Is an experiment actually conclusive?
What does the data say—and what can’t it say yet?
Growth Opt Playbook turns campaign CSVs or Google Sheets into practical answers for those questions.
It includes an operations dashboard, budget-allocation simulator, campaign saturation and variance analysis, creative analysis, A/B and incrementality tools, marketing-response analysis, and an Aha-moment finder.
Using AI for analysis always requires tokens, and there's the issue of getting different results every time.
That's why I turned it into a single deterministic model.
A few principles mattered while building it:
• Free to start, with no signup required
• Raw marketing data stays in the browser—nothing is sent to a server
• Results should lead with a plain-language conclusion and next action, not just a chart
• When the data cannot support a confident answer, the tool should say so instead of manufacturing certainty
I’d especially love feedback from performance marketers and growth teams:
Which decision do you spend the most time making from CSV exports today?
Which analysis would make this more useful in your weekly operating routine?
Is the browser-only data approach important for your team?
Thanks for taking a look—I’ll be here all day to answer questions and learn from your feedback.
