What Personal AI is

Personal AI builds a personal language model from what you write, and positions it as an assistant that represents you rather than a general chatbot. You feed it notes, messages and documents, and it answers in a style derived from that material; the company also works with carriers on messaging agents that run on the network rather than inside an app. The pitch is memory and identity: an assistant that knows your context without re-explaining it each time. The limits are evidence and scope: quality depends entirely on what you feed it, public documentation is thin, and claims about on-network deployment are hard to verify independently. It is worth piloting with non-sensitive material before trusting it with anything important. An API allows the model to be called from other software, so it is not limited to the company chat interface. Because the corpus is yours, answers can be checked against the material you supplied.

Individuals experimenting with a private model

Not ideal for

Team knowledge management
Work that needs independently verified security claims

Pros

Agents can run in messaging rather than a new app
Free tier allows a real pilot

Cons

Quality depends entirely on what you upload
Thin public documentation
Security and deployment claims are hard to verify

Pricing in detail

A free tier allows a limited personal model and message volume. Paid plans are billed monthly and raise message limits, memory size and API access; business tiers add team features and are quoted. Because the product is memory-centric, cost tends to grow with the size of the corpus you maintain rather than with the number of users.
