## Frequently asked questions

### What is the biggest difference between Vezz me and AI sidebar extensions?

Sidebar extensions like Sider, Monica, and Merlin open a persistent chat panel next to the webpage, narrowing the viewport and separating the answer from the source text. Vezz me opens a compact answer overlay right next to the passage you highlighted so you can read the source and explanation together.

### Why do these comparisons recommend competitors for certain workflows?

Because no single extension fits every browser habit. If you want image generation, email drafting, ChatPDF, or scheduled page monitoring, tools like Sider, Monica, or HARPA AI are genuinely better choices. Vezz me is purposefully built for one job: understanding selected text on the page you are reading.

### How is pricing compared across AI Chrome extensions?

Many AI sidebars use credit tiers split across basic and advanced models, or advertise monthly rates that require annual billing. Vezz me offers a Free plan (10 answers/month, no credit card) and a flat $12/month Pro plan with unlimited answers under fair use.
