Personal AI vs Pi (2026): which should you pick?

Pick Personal AI if

• Fits if you are a carrier or enterprise looking at an AI memory layer
• Works for developers who want a memory service behind their own AI

Look elsewhere if

• Skip it if you want a price you can read, as pricing is scoped with sales
• Not for you if you want to try it free, as no free plan or trial is listed
• Too light on public detail for a solo buyer, as the pages focus on enterprise deployments
• Watch out: its benchmark claims were measured on a carrier network and this directory has not checked them

Pick Pi if

• Fits if you want to talk a decision or a worry through before you act on it
• Works for people who'd rather speak than type, since there's a live voice mode

Look elsewhere if

• Skip it if you need files read, images made or code written, as its listings mention none of them
• Not for you if you want the app in your own language, because the App Store shows English only
• Not for you if you're choosing for a teenager, since the App Store rates it 18+
• Watch out: there's no desktop app, nothing it connects to and no API, so on a computer it's a browser tab

Personal AI

• No public prices were found. The pricing page says deployments are scoped with the sales team, and the pages offer Talk to Sales and a carrier briefing.
• The current pages focus on enterprise and carrier deployments, so a self-serve consumer plan for My AI could not be confirmed.
• Only a web sign-in is visible on the pages read, and no apps or browser extensions are listed.
• The model page cites production benchmarks measured on a carrier network, which this directory has not checked.

Pi

• The app listings describe conversation only, with no mention of file analysis, image generation or coding tools.
• The App Store listing shows English as the app's only language.
• The App Store gives the app an 18+ age rating.
• The listings cover iPhone, iPad and Android; no desktop app is listed, so on a computer Pi is used in a browser.
