Pros and cons

Grammarly

Pros

  • Works across desktop, browser, Office, Google Docs and mobile keyboards, so suggestions follow you between apps.
  • Free plan covers core grammar, spelling and tone visibility with 100 AI prompts per month.
  • Pro adds tone adjustment, full-sentence rewrites, plagiarism and AI-text detection in a single subscription.
  • Team features include style guides, brand tones, analytics and user groups; Enterprise adds SSO, SCIM and audit logs.
  • Public REST APIs exist for analytics, licence management, writing score and detection.

Cons

  • Monthly billing for Pro is $30, versus $12 per month on annual billing, so month-to-month use costs 2.5 times as much.
  • Third-party tests of the AI Detector report notable false-positive rates (figures range from 14.2% to 34% across sources), so it is unreliable as proof.
  • An App Store reviewer criticizes the iOS keyboard setup for pushing users to grant broad access.
  • Experienced writers on forums report turning off many suggestions; advanced features are gated behind Pro.

Novastart

Pros

  • Agents work with a visible cursor and can be paused, steered or taken over
  • Permanent free plan with all apps available
  • Pro at $10 per month removes canvas limits
  • Local-first design keeps canvas contents on the user's machine
  • Peer-to-peer canvas sharing with per-person cursors

Cons

  • The app is a full computer in a window and the site warns to expect some lag
  • App supports only Windows and Intel Macs, and needs 8 GB RAM and virtualization
  • Novastart OS replaces the existing system on the PC it is installed on
  • Agent use costs extra on every plan and needs credits of $25 or more
  • Young product launched in September 2026 with little independent review history
