Which plan to pickStart on Free to see if the writing suits you. Most people who stick with it move to Pro within a month; only go to Max if you hit the Pro limits every day or you're running Claude Code for hours at a time.Stay on Free unless you also want a VPN. Plus is good value if you'd pay for a VPN anyway. Pro is $19.99, the same as ChatGPT Plus or Claude Pro, so only pick it if anonymity matters more to you than features.Stay on the free plan. The paid Meta One bundles only raise image and video limits, and Meta doesn't publish the actual numbers, so only pay if you're making a lot of AI visuals for social.

  • One subscription covers Claude Code as well
  • The free plan now includes memory, connectors and Artifacts

Cons
  • Free and Pro usage limits can bite on a busy day
  • No image or video generation, which ChatGPT and Gemini both have
  • The free plan doesn't include the top Opus models
  • Fewer third-party connectors and plugins than ChatGPT
  • Free models are the small versions, so answers trail paid ChatGPT or Claude
  • No projects, connectors or spreadsheet uploads, and PDFs are capped at 15 to 50 pages
  • Usage limits aren't published as numbers
  • Privacy rests on DuckDuckGo's contracts with the AI companies, and some users report chat sync errors between devices
  • Chats are used to target ads on Meta's apps, with no opt-out in most countries
  • Answers still trail ChatGPT, Claude and Gemini, and glasses owners often call it vague or unreliable
  • Hard to fully remove from WhatsApp, Instagram and Facebook if you don't want it
  • Few connections to work apps, no team plan, and newer features arrive country by country
  • The Meta AI app that runs Ray-Ban glasses is buggy: crashes, login loops and battery drain are common complaints
