Grammarly score8.2/10

Strengths

  • Works nearly everywhere via browser extension and desktop app, not just one editor
  • Tone detection helps catch messages that might land wrong before sending
  • Business tier's style guide keeps team writing consistent
  • Low-friction inline suggestions rather than a separate tool to open

Trade-offs

  • Free tier is limited to basic grammar/spelling, not tone or clarity suggestions
  • Occasional suggestions feel generic or slightly off for technical writing
  • Some users find the constant underlines and popups distracting
