Which plan to pickStay 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.Start free and see how often you hit the Pro search limit. If you research most days, Pro pays for itself in saved tabs. Its 4,000 bonus Computer credits are a one-off and run out after about 30 days, so don't count them as a monthly allowance. Max only makes sense if you're using the Computer agent heavily enough to burn through the credits.Start free; most people never need to pay. Go at $4 is cheap if you hit the chat limits. Prices are App Store prices, so check the in-app screen before you subscribe.

Pros and cons

AttributeDuck.aiPerplexityQwen Chat
Pros

  • Free access to models from OpenAI, Anthropic and Mistral in one place
  • Fast, clean and easy for anyone to use
  • Paid plans bundle a VPN and identity protection
  • Sources on every answer make it the easiest assistant to fact-check

  • Broad toolkit: research, slides, websites, images and video in one place
  • Top Qwen models rank near the best US models
  • Open models you can run yourself
  • International service is run from Singapore
Cons
  • 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
  • Weak for long writing, planning or creative work
  • Computer credits are confusing: Pro's bonus credits expire after about 30 days, and Comet's browser actions and Automations spend them
  • Sources are sometimes low quality, so you still need to read them
  • Max is expensive for what most businesses need
  • Avoids or slants topics sensitive to the Chinese government
  • Thinking mode on the newest models can be very slow
  • Paid plans are new and the free limits aren't published, so it's unclear how long the free plan stays this generous
  • Chats can be used, de-identified, to improve the service; you have to email to opt out of training
  • No connections to business apps
