What our research says

Jetwriter AI

The right shape if your writing happens inside Gmail, LinkedIn and support tools and you resent tabbing out to a chat window. For long-form documents it is the wrong tool entirely.

Pros

  • Learns tone from your own Gmail history rather than a generic style picker
  • Three model vendors covered by a single subscription
  • Works on arbitrary web pages, not just a fixed list of supported apps
  • Free tier is genuinely usable for occasional drafting

Cons

  • Free plan is 15 responses a month with no advanced-model access
  • $18/month is steep beside assistants already bundled into Gmail and Outlook
  • No developer API
  • Safari and Firefox builds still have not shipped

Shortwave

Still the most capable AI layer we have seen on top of Gmail, and it is now cheaper to try: a free plan and an $18 individual Pro tier sit below the $30-plus business seats. The value is in asking questions of years of old mail, so people who only triage today's inbox will not get much from the paid tiers.

Pros

  • Free plan and an $18 individual tier make it possible to test the assistant without a business seat
  • AI search answers questions across the mail archive, not just keyword hits
  • Model tier, AI quota and filter count scale clearly from plan to plan
  • Native apps on all major desktop and mobile platforms

Cons

  • Business seats at $30 to $120 a month are expensive next to Gmail's built-in AI
  • Free plan limits search history to 90 days and adds a Shortwave signature to sent mail
  • No annual discount is offered; billing is monthly only

Which one fits
