What each one is actually for
Jasper
Jasper is $49/mo Creator ($39/mo billed annually) and $69 per seat per month for Pro ($59 annually). Business is a custom quote. There is no permanent free plan, only a 7-day trial.
Best for: Marketing teams that need brand voice enforced across many writers.
Not for: Solo writers — per-seat pricing punishes small teams.
The Pro rates are first-party, read from jasper.ai/pricing. The Creator rates are third-party (independent pricing breakdowns) because Jasper renders the Creator card with JavaScript. Verify on Jasper's page before you buy.

Copy.ai's self-serve Chat plan is $29/mo ($24/mo billed annually, $288/yr) for 5 seats. Everything above that is enterprise-priced: Growth $1,000/mo, Expansion $2,000/mo, Scale $3,000/mo.
Best for: Sales and marketing teams that want GTM workflows, not just a chat box.
Not for: Individuals — the useful tiers start at $1,000/mo.
The Chat plan and the Growth / Expansion / Scale enterprise rates were read from copy.ai/prices itself. Only Chat is self-serve; everything above it is a sales conversation, so treat those numbers as list prices rather than what a team actually signs.

Writesonic is $79/mo Starter, $199/mo Basic and $399/mo Growth billed annually, or 20% more month to month. It has repositioned from AI writing to AI search visibility tracking.
Best for: Brands that want to track how ChatGPT and AI Overviews describe them.
Not for: Anyone shopping for a cheap AI article writer — that is no longer what this product is.
Starter / Basic / Growth and the annual savings were read from writesonic.com/pricing itself. Those are the annual-billing rates; the page's own toggle says month-to-month is 20% higher.

- Write down the number of people who will log in. That is your seat count, and it is what the price scales on.
- Check the free tier against your real list size or contact count, not the marketing number.
- Only pay for the tier that removes the wall you have actually hit.
- Re-check the price before you buy — every number here is re-read weekly, but vendors change tiers without notice.
Some links on this page are affiliate links. If you buy through one we may earn a commission at no extra cost to you. It does not change the prices shown, which are read from the vendors' own pages. Full disclosure.
