Where each stands

Grammarly

Pros

  • Works nearly everywhere you type, which is a genuinely different experience from a standalone editor
  • Real-time suggestions catch errors before you hit send, not after
  • Free tier covers the core grammar and spelling checking most people actually need

Cons

  • Full generative rewriting and advanced tone features are gated behind paid tiers
  • Suggestions on stylistic choices can be overzealous, flagging intentional phrasing as an error
  • Business and Enterprise pricing is a real step up from the individual plan

Otter.ai

Pros

  • Auto-joins calls across the major conferencing platforms without manual setup
  • Summaries and action items save time re-listening to recordings
  • Transcript search makes finding a specific moment in an old meeting fast

Cons

  • Free tier caps out at 300 minutes a month with a 30-minute limit per conversation
  • Accuracy drops noticeably with heavy accents, crosstalk or poor audio
  • Business plan has a 5-seat minimum, which is awkward for very small teams

Which should you choose?

Grammarly is the better fit for:

  • Proofreading emails, documents and social posts as you write them

  • Catching grammar and clarity issues across every app you write in
  • Rewriting stiff or wordy drafts into cleaner prose
  • Holding a whole team's writing to one house style
  • Writing confidently in a second language across every app you use

Otter.ai is the better fit for:

  • Capturing notes from recurring team standups and client calls
  • Producing a searchable archive of meeting transcripts
  • Turning a lecture or interview recording into text for review
  • Finding what was decided across months of meetings without rewatching them
  • Sending a recap and action list without writing one
