App? Uh…idk about app, per se.

Perplexity.ai is a search engine, it’s like Google on steroids. I’m researching online graduate programs, and I like how I can ask for tables to compare different programs side by side easily. With Google, I’d have to manually create that.

Perplexity.ai has an app, if that counts…

CatGPT

Either the chatgpt website on desktop, or the official chatgpt iOS app

There is an opensource Alternative i like called huggingface : https://huggingface.co/chat/ https://github.com/huggingface . You can even try different models and languages.

I just have a shortcut on my homescreen to the site. It’s such a simple interface, why would it need an app?
