Qwen Chat
Qwen Chat is Alibaba's free conversational app built on the Qwen model family, one of the most capable open-weight model lines in the world. The consumer app is permanently free with no obvious message caps -- web, mobile, and desktop -- which undercuts every Western rival on price. Developers can call the same models cheaply through Alibaba's DashScope API (OpenAI-compatible), though the always-free dev tier was replaced by a finite trial in 2026. Its main drawbacks are China hosting, a compliance concern for Western firms, and a consumer UX that trails ChatGPT.
Pi
Pi, from Inflection AI, is an empathy-first 'personal AI' tuned for supportive, natural conversation and voice rather than tasks. It's free with no paid consumer tier (now with some message caps), works across web and mobile, and has a uniquely warm, low-friction tone with eight voices. But after Inflection's founding team left for Microsoft in 2024 and the company pivoted to enterprise, Pi has sat in maintenance mode -- it still runs reliably, but the roadmap is uncertain and the feature set is frozen. It's lovely for companionship, but not something to build a workflow on.
Qwen Chat edges Pi on aggregate — 87 vs 56.
Unbeatable price -- a fully free app and dirt-cheap open weights with a relentless release pace -- but China hosting caps its appeal for Western businesses. Pi still wins for buyers who prioritise genuinely free, no card, no paid upsell. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
