Pros and cons

Fireflies.ai

Pros

  • Permanent free tier with unlimited transcription and 100+ language support.
  • Works across Zoom, Google Meet, Microsoft Teams and other platforms, plus file uploads.
  • Broad integrations covering CRM, ATS, dialers, Slack and an MCP server.
  • Conversation analytics and team insights on the Business plan.
  • Web, iOS, Android and Chrome extension coverage plus a desktop app with a public API.

Cons

  • Free plan limits AI summaries and caps storage at 400 minutes per team.
  • Per-seat pricing rises quickly for teams: Business is $29 per seat on monthly billing.
  • AI credit pools are small (20 to 50 per plan), and some features consume credits.
  • HIPAA compliance, SSO and audit logs require the sales-led Enterprise plan.

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.
