Comet's Android Launch Is Perplexity Admitting Desktop Isn't Enough

Perplexity's Comet browser has landed on Android, more than a year after it launched on desktop, and Perplexity is explicit about why it took this long: it did not want to just force a desktop experience onto mobile. Comet for Android is a rebuilt mobile browser, not a shrunk down version of the desktop app, with an assistant that can summarise every open tab, a voice mode, and an ad blocker built in rather than bolted on.

The delay is the interesting part. Building an agentic browser that actually works on a phone, where screen space, battery and interruption patterns are completely different to a desktop session, is a harder problem than most AI browser launches have admitted. OpenAI's Atlas never made it past macOS before it was retired entirely.

If agentic browsing is going to matter to anyone outside people who already spend all day at a desk, mobile is where it has to prove itself, not desktop. A browser that only works well when someone is sitting at a laptop is a tool for a shrinking slice of how people actually use the internet.
