Migration Playbook: Switching Without Friction
Swapping a daily driver mid-project is costly. Follow this three-step checklist to evaluate Otter.ai and ProWritingAid on equal terms before standardizing your team.
Export Config, Prompts & Data
Inventory what each candidate needs: prompt libraries, templates, connected accounts and project files. Export from your current stack first so Otter.ai and ProWritingAid start from the same baseline.
Map Pricing to Your Real Usage
Compare published entry tiers against your expected volume. Otter.ai starts at $8.33/mo (freemium); ProWritingAid starts at $10/mo (freemium) — model the monthly cost at your actual workload before committing.
Run a Two-Week Parallel Trial
Run both tools on the same live tasks for ten working days. Score outputs against the five Airecmark dimensions, then let the 0.1-point composite gap — not vendor marketing — decide the standardization call.
