Why people switch from Perplexity Pro
Research + build in one free tool.
Unchained runs on open, OpenAI-compatible models (DeepSeek, Qwen, GLM, Kimi, MiniMax) that cost roughly 10× less per token than frontier models. That gap is passed straight to you: the free tier is the product: free to start, no lockouts.
