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.

Gemini Notebook

Pros

  • Answers cite the uploaded sources, so claims can be checked against the original text
  • Free Standard tier with 100 notebooks and 50 sources per notebook
  • Wide range of outputs, including Audio Overviews, Video Overviews, mind maps, flashcards, quizzes and slide decks
  • Accepts PDFs, websites, YouTube videos, audio files, Google Docs and Google Slides
  • Available on web, iOS and Android, and synced with the Gemini app

Cons

  • Works from the sources you add and is not built for live web news search
  • Higher limits require a Google AI subscription; Ultra starts at $99.99 per month
  • The cloud computer for code execution started with Ultra and Workspace AI Ultra Access customers, with Pro rollout still described as upcoming
  • No public API for the consumer product, and the renamed brand can make older guides and app listings confusing
