Pros and cons

Claude

Pros

  • Free plan includes web search, file creation, code execution and memory
  • Artifacts show generated code and pages beside the chat
  • Claude Code is included with Pro, Max, Ultra and Team
  • Connectors use MCP to reach Slack, Google Workspace and other tools
  • Available on web, desktop, iOS and as a Chrome extension, plus an API and major cloud platforms

Cons

  • Usage limits on every plan, with weekly caps (and five-hour caps below Ultra) and no published message counts
  • Does not generate images
  • The higher individual tiers are costly: Max is $100 per month and Ultra is $200 per month
  • Linux desktop app is still in beta

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.
