I’ve spent the last 90 days testing 2 leading note takings: Agenda and IA Writer. This isn’t another feature list comparison—it’s a founder-focused analysis of what actually works in real workflows.
Bottom line first: Each tool serves different needs. Here’s my recommendation based on your situation:
- Choose Agenda if you need date-focused notes and work as project managers ($24.99/year)
- Choose IA Writer if you need focus mode and work as writers ($49.99 one-time)
Why This Comparison Matters
Most note taking reviews chase features. Founders care about ROI, adoption friction, and whether this tool actually ships value. I tested each app in real workflows, tracked time saved, measured onboarding friction, and evaluated long-term viability.
For indie hackers, solo devs, and small teams building products—not just collecting tools.
