Pros and cons

Lumo

Pros

  • Zero-access encryption on saved chats, with a stated no-logging policy.
  • Open-source code and open-source models that can be inspected.
  • Permanent free tier with guest access and no credit card.
  • Web, iOS and Android apps.
  • Run by Proton AG, a Swiss company, and stated to comply with GDPR.

Cons

  • Free chat history is kept for only 7 days.
  • Uses open-source models rather than the proprietary frontier models of larger rivals.
  • No desktop app or public API found.
  • Lumo Plus limits are described only as "more" than Free, not as numbers, and the plan costs $12.99/month ($9.99/month billed annually).

Qwen

Pros

  • Free web assistant with image, video and document features
  • Open-weight models in many sizes on Hugging Face and GitHub
  • Hosted API with Max, Flash and Omni model options
  • Strong multilingual coverage, including Chinese
  • Many models can be self-hosted, which keeps data on your own hardware

Cons

  • No published paid consumer tier or stated usage limits for the free assistant
  • Open-weight licenses vary by model, so not every model is Apache 2.0
  • Hosted chat and API are run by a China-based company, which may not suit sensitive data
  • App and model names change often, which can make official apps hard to identify
