Personal AI vs rabbit OS3 (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 rabbit OS3 if

• Fits if you want to hand over a whole job, such as research or sorting files, in a sentence
• Makes sense if you already own the rabbit r1 and want it to do more

Look elsewhere if

• Pricey if you use it heavily: the plans jump from $20 to $99 to $199 a month
• Watch out: usage resets every Friday and what you don't use is lost
• Watch out: there's also a five-hour limit, so capacity comes back slowly after a busy stretch
• Tight if you top up: credits are $5 for 250 and need an active plan
• Skip it if you want to see figures first, because the page shows no usage numbers

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.

rabbit OS3

• Included usage and phone minutes refresh every Friday at 12:00 UTC and unused usage does not carry over.
• Each plan also has a five-hour usage limit, so capacity returns gradually.
• Extra credits cost $5 for 250, $40 for 2,500 or $120 for 10,000, and buying them needs an active plan.
• The pricing page shows no usage figures for the plans, only relative levels.

Describe a result, not the steps

OS3 works through the steps of a request and comes back when a decision is the user's.

Connected computers

It can use files and tools on connected computers, including sorting and renaming files, and one task can involve more than one machine.

Phone calls

Plans include weekly phone minutes for standard US and Canada numbers, up to 15 minutes a call.

Several ways to reach it

Use it in a browser, the desktop app for macOS and Windows, iMessage, RCS or SMS, a paired Telegram bot, or by speaking to r1.

Hosted or bring your own model

The rabbit-hosted model is the default. A custom model with your own API key, a local model or a custom endpoint is not charged by rabbit.
