Analyze user engagement and retention patterns by cohort to identify trends in user behavior, feature adoption, and long-term engagement. Combine quantitative insights with qualitative research recommendations.
How It Works
Step 1: Read and Validate Your Data
Accept CSV, Excel, or JSON data files with user cohort information
Verify data structure: cohort identifier, time periods, engagement metrics
Check for missing values and data quality issues
Summarize key statistics (cohort sizes, date ranges, metrics available)
Step 2: Generate Quantitative Analysis
Calculate cohort retention rates and engagement trends
Identify retention curves, drop-off patterns, and anomalies
Compute feature adoption rates across cohorts
Calculate month-over-month or period-over-period changes
Generate Python analysis scripts using pandas and numpy if requested
Step 3: Create Visualizations
Generate retention heatmaps (cohorts vs. time periods)
Create line charts showing cohort progression
Build comparison charts for feature adoption
Visualize drop-off points and engagement trends
Output as interactive charts or static images
Step 4: Identify Insights & Patterns
Spot one or more significant patterns:
Early churn in specific cohorts
Late-stage engagement changes
Feature adoption clusters
Seasonal or temporal trends
Highlight surprising findings and deviations
Compare cohort performance to establish baselines
Step 5: Suggest Follow-Up Research
Recommend qualitative research methods:
Targeted user interviews with churning users
Feature usage surveys with engaged cohorts
Session replays of key interaction patterns
Win/loss analysis for high vs. low retention cohorts
Design follow-up quantitative studies
Suggest A/B tests or feature experiments
Usage Examples
Example 1: Upload CSV Data
Upload cohort_engagement.csv with columns: cohort_month, weeks_active,
user_id, feature_x_usage, engagement_score
Request: "Analyze retention patterns and identify why Q4 2025 cohorts
underperform compared to Q3"
Example 2: Describe Data Format
"I have monthly user cohorts from Jan-Dec 2025. Each row shows:
cohort date, user ID, purchase frequency, and support tickets.
Analyze which cohorts show best long-term retention."
Example 3: Feature Adoption Analysis
Upload feature_usage.xlsx with cohort adoption data.
Request: "Compare adoption curves for our new feature across cohorts.
Which cohorts adopted fastest? Any patterns?"

Tips for Best Results
Include time dimension
Provide data across multiple time periods
Define cohort clearly
Make cohort grouping explicit (signup month, feature launch date, etc.)
Provide context
Explain product changes, launches, or events during the period
Multiple metrics
Include retention, engagement, feature usage, revenue, etc.
Sufficient data
At least 3-4 cohorts for meaningful pattern identification
Request specific output
Ask for visualizations, Python scripts, or research recommendations
(if requested): Python code for reproducible analysis
Next Steps
Prioritized actions based on findings
