Short answer: start free everywhere. Upgrade only the single tool where limits interrupt real work weekly.
The free tier reality
Most major tools — ChatGPT, Claude, Gemini, Perplexity, Canva, Otter — offer functional free tiers. For occasional use, they're genuinely enough. The catch is limits: message caps, slower models at peak, feature gates.
When paid becomes rational
- A limit costs you an hour+ of waiting or workaround time in a week
- You need the paid feature (not just more volume): deeper research modes, longer context, team workspaces
- Client delivery depends on consistent access
The upgrade math
Most plans run $10–25/month. If your hourly value is $50+, breaking even requires saving about 30 minutes monthly. Track limit-hits for two weeks using our free scorecard; the decision makes itself.
One warning
Don't stack subscriptions "just in case." Five partial tools beat by two well-used ones. Annual billing locks you in — prefer monthly until you're certain.
