Experimentation
Test, learn, and ship what works without code
Run A/B tests, multivariate experiments, and feature flags across every in-app experience. Smart Switch auto-picks the winner. AI generates your variants. Goal events prove what moved the needle.
Trusted by product & growth teams at top consumer apps
Everything you need to experiment at scale
From variant creation to automatic winner selection — run rigorous experiments without waiting on engineering.
A/B & Multivariate Testing
Test unlimited variants per campaign and find the winner
Create multiple variants of any in-app experience — each with different copy, visuals, CTAs, or targeting rules. Split traffic manually or let Smart Switch optimize automatically.
- Allocate traffic across unlimited variants with manual splits
- Track impressions, clicks, and conversions per variant in real-time
- Promote the winning variant to 100% of users with one click
Smart Switch
Auto-pick the winner with Bayesian optimization
Stop watching dashboards and waiting for statistical significance. Smart Switch uses a Multi-Armed Bandit algorithm to automatically shift traffic toward the best-performing variant.
- Bayesian Multi-Armed Bandit — no fixed test duration needed
- Set your confidence interval (90%, 95%, or 99%) and a goal event
- Traffic reallocation happens automatically as results accumulate
Feature Flags
Roll out features safely with Boolean or Multivariate flags
Ship Boolean toggles or Multivariate flags with custom payloads — strings, arrays, or full JSON objects. Control rollout percentages per variant and target specific audiences.
- Custom payloads let your app dynamically build different UIs from flag values
- Audience targeting and scheduling for gradual rollouts
- Works across Android, iOS, React Native, Flutter, and Web SDKs
Generate campaign variants with a single prompt
Describe what you want to test and AI creates up to 3 variants — different headlines, body copy, and design variations — while preserving your campaign structure and step layout.
- Go from idea to live experiment in seconds, not hours
- AI preserves your campaign structure while varying creative elements
- Edit generated variants or use them as-is with one click
Track any event as your north-star metric
Set any frontend or backend event as a goal — purchases, signups, feature activations. The SDK automatically attributes goal completions to the correct variant with zero extra code.
- Define conversion windows that match your user journey (1-30 days)
- Per-variant performance tables with users, goals, rate, and lift metrics
- Filter events by occurrence count, recency, properties, and AND/OR logic
Teams that experiment faster with Plotline
"The time to launch campaigns in our apps was significantly reduced, allowing us to implement changes swiftly and efficiently without code. Our CTRs soared with the personalized in-app approach."
"Plotline has transformed how we experiment and scale new features. The ability to launch campaigns directly from the dashboard, without relying on engineering, has been a game-changer."
"We've tried building in-app campaigns in-house. Significant time was required to build and release multiple experiments. Using Plotline, we've been able to rapidly decrease time to go-live."
