A local AI team for small regulated firms: knowledge search, meetings, tasks and client memory, with no data leaving the office.
Prismatic Agents makes Prismatic. Its row is first, highlighted and labelled, so you can compare every solution against it; the others follow alphabetically and are ranked by nobody. Every value carries an evidence label; "Where Prismatic leads" is our view as its maker.
Law firms, clinics and accountants want AI for documents, email and meetings, but client confidentiality pulls against cloud AI. The big assistants now offer data residency in-country, which is not the same as nothing leaving the building. A small but real on-premises field is growing.
Machines and chips in use: No robots: office PCs, a document store, and either a cloud tenant or an on-premises server.

Sector price: US$22 per person a month, unlimited. Proposed list prices in US dollars; change the numbers and everything updates.
What this sector pays today: Enterprise AI seats US$30 per user a month on top of the base suite (Microsoft 365 Copilot) (Published, source). That is often a whole product; Prismatic adds the lasting local memory beside it. Hardware is bought by you from Apple or NVIDIA. Electricity at 14.2¢/kWh around the clock. Prices are proposals until the first customer agrees them. How Prismatic is licensed
Per-seat cloud AI against one local box over the years.
How it works: cloud = staff × seat × 12 × years; Prismatic = Mac mini once + staff × licence × 12 × years (unlimited turns).
One card per solution. Strengths first; gaps are about this job, not about the product being bad.
Our review. The leading legal AI, with strong security certifications and no training on customer data.
Gaps for this job. Cloud-hosted; priced for large firms.

Gaps for this job. In-country is still the cloud: client data leaves the building.

Our review. Genuinely local AI inside a full self-hosted office suite.
Gaps for this job. An assistant feature, not a team with lasting memory, meetings and follow-through.

Our review. Popular open-source private AI (50K+ GitHub stars) with an enterprise appliance.
Gaps for this job. A private-AI backend and chat over documents; not a lasting team.

Host: Mac mini M5 Pro 64 GB as the site's control centre (retrofit).
Hosts. Prismatic runs on a 64 GB Mac mini (M5 Pro) beside machines that already work, and is carried next into new machines on the Jetson AGX Orin 64 GB, the host for greenfield sites.
Licence here (proposed sector price, US$): US$22 per person a month, unlimited turns. What this sector pays today: Enterprise AI seats US$30 per user a month on top of the base suite (Microsoft 365 Copilot) Published source. Design-partner pilot: US$5,000 for 90 days, credited in full to the first year's licence. How Prismatic is licensed
Status: Runs today: the studio's team of agents, memory, meetings, knowledge and documents, all local. Features used: Knowledgebase search, Sources per reply, Contradiction finder, Meetings + decisions, Native board, Confirm-before-write, Local-only, Receipt ledger / audit, Genesis.
A day with it: A paralegal asks what the firm decided about a client's filing deadline; the answer cites the meeting decision and the card that tracks it.
Genesis Blueprint · Business blueprint (BRD)
A whole AI team inside the office: knowledge, meetings, tasks and client memory, and nothing leaves the building. Offering clients a private, local AI practice is a business decision with revenue and risk, so a Business Requirements Document fits.
In a Prismatic studio this blueprint waits in the Marketplace, ready to be born: Genesis gives each role an original name, look, voice and character, and nothing starts until the founder presses Generate. Founders can also write their own blueprint step by step in the Blueprint Builder.
Scores are first-pass hypotheses from general industry knowledge (UseCase file 05), not researched market sizes.
For patient investors
Retrofit sites pay first on a 64 GB Mac mini (M5 Pro) beside machines that already work. Greenfield machines carry the same mind inside, on the Jetson AGX Orin 64 GB, licensed per machine. The horizon (blackouts, wilderness, space) is where a mind that needs no cloud is not a feature but the point.
