PH LABS

Persinger / Herrada Labs — Software engineering studio

Any software.We build it.

PH Labs is a software development company. Whatever software you need, we can build it. For your customers, your business, or an idea the world hasn't seen yet.

Fig. 01 — Section A–A · MayaClerk for iPhone

One product, cut open. The screen in front is the real app; every sheet behind it is a part we built.

02 — What do you need?

Your software.
Built around your idea.

A product to launch. A better way to run your business. A tool that does something entirely new. Bring us the idea; we design and build the software to make it work.

Web & mobile applications

Customer apps, websites, native iPhone applications and the backend services that connect them.

Business software & platforms

Subscriptions, commerce, accounts, administration, dashboards, document workflows and tools for your team.

AI that knows its user

Assistants and companions with a personality, persistent memory, reflection and controls the user can see.

Voice, characters & virtual worlds

Original voices, spoken conversations, editable avatars and AI characters brought into Unreal Engine.

Search & research software

Find, connect and understand documents. Research agents, source-linked answers and knowledge systems for any field.

Games, simulators & 3D experiences

Scientific models, live instruments, geographic worlds, interactive visualization and immersive interfaces.

APIs & connected systems

Custom services, SDKs, model gateways, identity, usage metering, real-time connections and durable workspaces.

Automation & developer tools

Data processing, integrations, Source Explorer, reproducible experiments and software that builds other software.

Combine them around the job. A research application can speak. A simulator can teach. A business platform can have its own AI. We build the parts and the complete product.

03 — The portfolio

Look at what
we've built.

Working software across very different fields. Explore the products, see the real interfaces and follow the engineering behind them.

01 / SR-71 · Scientific simulation

From NASA research to a working simulation.

The SR-71A in the running Unreal simulator, viewed from behind on the runway. The SR-71A cockpit with sixteen dials driven by the flight model.
Actual simulator captures. Third-party aircraft and cockpit models; terrain: Google Photorealistic 3D Tiles through Cesium. Flight modeling, aircraft systems, instruments and sound by PH Labs.

What we built

Published NASA research translated into a flight model, connected to JSBSim dynamics and an Unreal world. Sixteen live SR-71 dials, configurable aircraft systems and geographic rendering; a DC-9 with 115 bound cockpit controls. Recorded comparisons make the model's behavior inspectable.

What you could build

Technical simulators, equipment demonstrations, engineering visualization and immersive training.

Explore the simulator

02 / AI companions · Voice & worlds

Create them. Speak with them. Enter their world.

Ryu, the companion behind the foreground player, embodied in an Unreal city. The companion conversation's voice studio, with speech and call controls.
Recorded Unreal build and voice interface. Epic City Sample environment and third-party character assets; PH Labs companion integration. These are interface captures, not a video demonstration.

What we built

A character's personality, editable appearance and original voice, carried into conversation and an Unreal environment. Customized CosyVoice 3 and faster-whisper support spoken interaction; persistent memory keeps useful context with source-linked reflections and user controls.

What you could build

Personalized assistants, conversational game characters, tutors, virtual instructors and branded experiences.

03 / MayaClerk · Web & native iPhone

A research engine with reach beyond law.

MayaClerk web search results with case citations and relevance indicators.
MayaClerk's native iPhone search screen, captured in the Simulator with test data.
Web: live legal research. Native iPhone: Simulator, test data; built and tested, not yet in the App Store.

What we built

Large-scale ingestion and retrieval by meaning, exact words and citation relationships. Source readers and a three-agent Dossier workflow compare opposing arguments and reconcile the evidence. One backend serves web and native iPhone interfaces.

What you could build

Medical literature review, financial evidence analysis, scientific discovery, regulatory intelligence and enterprise research, using your own sources and workflows.

04 / Complete software systems

The application and everything behind it.

The CreatorsHub three.js lounge, with bookshelves and a window over a night city. The PH Labs JavaScript SDK interface with service documentation and a playground.
CreatorsHub's browser lounge and the reusable SDK. The MayaClerk developer API is public; the wider service platform runs on our own infrastructure.

What we built

CreatorsHub's creator, content, account and subscription workflows alongside its AI experience. Nine services behind one SDK, identity, metering and real-time integration. The Factory coordinates engineering, independent QC and reuse across the software we deliver.

What you could build

Subscription platforms, internal tools, native mobile products and connected services, with the interface and operating software designed together.

04 — More working software

The range goes
much further.

We build the tools behind the experiences, too. Here are more of the applications and services already in the portfolio.

Original voice creation and audition controls in Voice Studio
Voice creation and audition interface.

Voice & Personality Studios

Create a character's personality and an original voice. Connect customized CosyVoice 3, faster-whisper, streaming speech and interruption handling for spoken interaction.

Explore voice and personality
The Memory Atlas displaying connected memories and their inspection controls
The real Memory Atlas interface.

Persistent memory & Memory Atlas

Keep useful context across conversations, connect memories to their sources and let users inspect, correct, forget or export what the system remembers.

Explore memory

Native iPhone app — Simulator, test data. Built and tested; not yet in the App Store.

Complete native iPhone applications

MayaClerk brings search, a research assistant, document reading and an account into a native SwiftUI app, connected to the same services as its website.

The Dossier research interface.

Research agents & document tools

Agents research a question from opposing sides, then reconcile the findings. The same document, search and relationship architecture can support medicine, finance, science and enterprise knowledge.

Explore research and document software
SDK documentation showing typed service methods, requests and responses
Real SDK methods and response contracts.

APIs, SDKs & reusable services

Nine services connected through one SDK. Model routing, memory, voice, identity and usage metering, alongside reusable components, durable workspaces and experiment tools.

The software Factory

A working engineering system that coordinates agents, creates child projects, reuses existing code and checks the result. Its output includes applications, services, SDKs and tools used in its own workspace.

06 — How we build

Every build adds to
what we can build next.

Our Factory turns requirements into engineering work, coordinates specialist agents and child projects, and puts the result through independent QC. Finished applications also contribute reusable code, interfaces and recorded engineering experience.

  1. 01 / Completed work

    Start with something real.

    Research engines, memory services and product interfaces provide concrete, inspectable foundations.

  2. 02 / Reusable capability

    Keep what transfers.

    Services become SDK clients and components. Their source, tests and delivery records remain traceable.

  3. 03 / Your next product

    Build the missing pieces.

    Combine that foundation with new engineering, then verify the application against its own requirements.
