QuanTiWen Fires One Question at 16 AI Chatbots Simultaneously
Cross-referencing multiple LLMs is a cheap, effective way to catch hallucinations and conflicting answers, but doing it manually across browser tabs is tedious. A single-pane tool that automates this comparison turns a good habit into a frictionless default.
QuanTiWen ("Ask All") is a browser extension that automates the manual grind of pasting the same question into multiple AI chatbots. Type a prompt once, and the plugin fans it out to a configurable set of assistants — DeepSeek, Doubao, GLM, Yuanbao, and others — rendering every response in a multi-column dashboard. The workflow emerged from a practical frustration: individual AI answers often contain subtle errors that only become visible when compared against competing models.
Beyond basic text prompts, the plugin handles image-based questions across three platforms simultaneously. A highlight mode lets users mark passages for later review, and exports cover PDF, Markdown, and PNG formats with the ability to stitch together selected sections from different answers. All chat history stays local, never touching a cloud server.
Built by a solo developer named Wuyang using Cursor, the extension has picked up 6,000 users in three months without any paid promotion. It remains free and non-commercial, funded only by voluntary tips from users.
Comparing answers across models is a low-tech but high-impact verification strategy that catches errors invisible in any single response.
Local-only storage for chat history addresses a real privacy concern that many AI wrapper tools ignore, especially in regions where data sovereignty matters.
The 6,000-user organic growth in three months suggests a genuine demand for multi-model comparison tools that the major AI platforms themselves have not addressed.
