Deterministic intelligence

Software that
doesn't guess.

We build deterministic engines and assistants: same input, same output, every answer traceable to a rule or a source. When it doesn't know, it stops and asks a person. Runs on your hardware. No cloud, no GPU.

What's running

Built, shipped, and measured.

Everything below exists and runs. Two are public. One is in delivery for a client. The rest run on-premise and can be shown live. Nothing here is a mockup: the window below is a real session, captured 2026-09-08.

A curated archive with an AI that answers only from the archive and cites every source. If it isn't in the archive, it says so. Try it: ask it something it doesn't know.

A composition engine
for a Miami DTC brand.

Custom family illustration on Shopify. The engine assembles the artists' own approved artwork by the rules the artists defined and outputs print-ready files. When two names collide or a piece needs an adjustment, it flags "review" instead of guessing. No generative AI in the composition.

  • Same order in, same file out
  • Print-ready PDF and PNG, three sizes
  • "Review" flag instead of a guess
  • Order API, asynchronous · contracted Sept 2026

Zymbio RH.
CV analysis, local-first.

Four layers on every CV: completeness, positive signals, cognitive profile, red flags. A holistic match against the role. Runs on the recruiter's own Mac; nothing leaves the machine. Signed licenses and a merchant of record for billing.

Zymbio Legal.
Cites verbatim, or abstains.

A legal assistant that answers only from the firm's own documents, quotes the passage verbatim, and stops when the answer isn't in the source. Deterministic retrieval. 100% on-premise, packaged as a macOS app.

  • Runs offline on the firm's hardware
  • Verbatim citation on every answer
  • Abstains outside its sources
  • Status: built · demo on request
§ 05 · Built · on-prem

Zymbio Médico.
A clinical record that cites.

A real clinical system: writable on-premise clinical database, patient records, appointments, population recall, and preventive guidance cited to USPSTF. Bilingual, built for US primary care.

  • On-prem clinical database
  • Records · appointments · population recall
  • USPSTF-cited preventive queries
  • Status: built · demo on request

X2R.
The same core, driving robots.

Simulated robots run by the deterministic core in a live web demo: warehouse, restaurant, battle, procedures. Every decision observable, step by step. Open the demo.

  • Live · Cloudflare Worker · $0
  • Isometric simulations, in the browser
  • Deterministic decisions, replayable
  • Status: live demo
§ 07 · Built · device

Zymbio X5.
A voice assistant on a tablet.

On-device, no cloud. Memory in five hemispheres: lexical, graph, procedural, vault, vector. Bilingual. It learns to speak from use. Native Android, running on a mid-range tablet.

  • Android (Kotlin) · on-device
  • Five-hemisphere living memory
  • No network required
  • Status: running on a Lenovo Tab P12
The core underneath

One brain. Many bodies.

Zalvyum is the memory-first deterministic core under every body above: routing, memory, composition, and a judge that decides whether an answer is grounded. The language model, when there is one, is a replaceable part that only phrases the answer. It never decides what's true. Measured 2026-09-08 on a laptop, same ten questions: 100 MB and no GPU, against 5 GB and the GPU for a 7B model.

How an engagement works

Fixed scope. Measured first.

Two ways we build for clients. Both start by measuring your real data before a line of code is written, and both ship with their own automated checks, so you know it worked without checking by hand.

§ A · Engines built to spec

The engine that replaces
the decision your team repeats.

A short call to find the repeatable half of the problem. A measured inventory of your real data. A fixed-scope build that runs on your hardware and replaces the decision your team makes by hand, deterministically.

  • Discovery call · the repeatable half
  • Inventory of real data, measured, before code
  • Fixed scope, fixed price
  • Ships with its own automated judges
§ B · Assistants on-premise

Answers from your documents.
Cited, or withheld.

Legal, clinical, or any regulated domain: an assistant that answers only from your sources, quotes them verbatim, and stops when the answer isn't there. Nothing leaves your machines.

  • Runs on your hardware, offline
  • Cites verbatim or abstains
  • A human gate on every uncertain answer
  • ES / EN
Who builds it

Founder-led. Engineered end to end.

Zymbiotech designs, builds, and ships the core, the bodies, and the judges that check them. No resold models, no assembled demos.

Founder · Systems architect

Erika Herrmann

Founder of Zymbiotech and architect of the Zalvyum core. Leads every engagement personally: the discovery, the measured inventory, the build, and the judges that prove it works. The differentiator isn't the AI. It's that what Zymbiotech ships doesn't guess.
