Perplexity vs PromptUnit

Perplexity and PromptUnit are both productivity tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Perplexity

Perplexity sits between a search engine and a chatbot: you ask a question, it searches the web in real time, and returns a synthesized answer with clickable source attribution. This solves the hallucination problem that plagues ChatGPT—you can actually verify where the information came from. The free tier lets you ask a few questions per day; paid plans (Pro at $20/month) unlock unlimited queries and access to multiple model options. The main trade-off is that Perplexity still lacks a native mobile app, forcing phone users to rely on the browser.

PromptUnit

AI proxy that automatically routes requests to cheaper models while maintaining quality.
