What is the GaiXer App Store?
A system to build, distribute and run AI apps
When rolling out generative AI company-wide, the final hurdle is getting the apps you build into each employee’s hands. The GaiXer App Store plays the role of a smartphone app store inside the AI server at your company. This article explores the second layer from the top of the four-layer structure introduced in Part 1.
In a sentence
The GaiXer App Store does for your company’s generative AI what an app store does for a smartphone. Publish a business app built on the Sovereign GaiXer AI-OS and employees can choose and use the apps they need as easily as installing a phone app. The AI-OS handles LLM operation, hallucination control, prompt injection defenses and user management, so you can create and distribute AI apps for your workflows without IT expertise. The Japanese one-time purchase price is JPY 3,806,400 (JPY 4,187,040 including Japanese tax), with no extra usage charge as apps or users increase, excluding electricity and other operating expenses. Overseas terms require confirmation with sales.
The store is second from the top—just like on a smartphone
As Part 1 explained, Sovereign GaiXer has four layers: PGX hardware, AI-OS, GaiXer App Store and business apps. The store sits second from the top in this diagram, exactly where a smartphone’s app store belongs.
SmartphoneThe device you use every day
Sovereign GaiXer Your company’s generative AI device
Without an app store, smartphone developers cannot easily reach individual users, and users may not even know which apps exist. Company AI faces the same problem. A store turns an AI app from its creator’s tool into a company-wide resource.
Build
Prepare an AI app for your own workflows. The AI-OS handles LLM management and safeguards, so creators can focus on what help they need and how it should work.
Distribute
Publish the finished app in the GaiXer App Store so people inside your company can choose and obtain it. This is the focus of this article.
Run
Apps run inside the PGX unit. Processing stays inside the company, without sending business data to the internet.
Protect
Hallucination control, prompt injection defenses, user management and audit logs: the AI-OS handles them without requiring every app to implement them separately.
Why “we built an AI app, but nobody uses it” happens
A common experience with business AI is a working prototype that never becomes a company-wide tool. Often the issue is not AI performance but the lack of a distribution mechanism. Consider what happens without a store.
- No practical delivery method: creators must tell people individually where the app is and explain its use in person or by email. Each transfer or new hire means repeating the explanation from scratch.
- No manageable access controls: HR or contract apps should be restricted to particular users, but developing login and permission systems for each app is impractical.
- Safeguards multiply with every app: individually implementing hallucination controls and prompt injection defenses is hard to sustain. A single unprotected app can become a weak point.
- Know-how stays with individuals: successful approaches remain on an expert’s computer instead of reaching the next department. They never become a company asset.

Differences when rolling out AI apps internally (as of August 2026; feature availability and scope may vary by configuration and edition). Commercial examples describe the Japanese offer.
Using AI without a store is like leaving a cooked meal in the kitchen without putting it on a plate. It may taste good, but nobody can collect or eat it. The store is the serving system that brings your AI app to the workplace table.
Build: why business apps do not require IT expertise
Smartphone app developers do not build the OS. It already supplies camera control, connectivity and security. The same principle applies to Sovereign GaiXer. The lower layers handle the difficult parts, allowing people to build apps without IT expertise.
LLM operation is handled for you
Deploying, starting and updating models in engines such as vLLM and Ollama, managing memory and concurrent users: these are the AI-OS’s job. App creators do not need to learn command-line operations.
Core safeguards are handled for you
Hallucination control and prompt injection protection are not simply ready-made switches; building them yourself requires expertise. The AI-OS handles these capabilities so each app does not have to implement them.
User management is handled for you
Account creation and suspension, separation of administrator and ordinary-user permissions, and automatic account locking after failed logins: the foundation for company-wide use is provided from the start.
Creators focus on the work
Which documents should be processed, from which perspective, and in what output format? The knowledge of the person who understands the work—not programming knowledge—becomes the substance of the app.
Distribute and run: employees choose apps, and data stays internal
When using a new smartphone app, we do not edit installers or configuration files. We find it in the store, install it and open it. The GaiXer App Store aims for that same everyday simplicity.
Choose it and use it
Employees can obtain the business apps they need much as they install phone apps. They no longer have to wonder where the app is or ask someone before they can start.
See who uses AI and how much
Graphs and CSV exports show AI use by person and department. Administrative actions and logins are recorded in audit logs. After rollout, adoption becomes measurable rather than guesswork.
Processing stays inside the unit
Apps run inside PGX and do not send internal data to the internet. This is particularly useful for contracts, personal information and clinical data that previously could not be sent to a cloud service.
Answers based on internal documents
Import PDF, Word, Excel, PowerPoint, images and audio so AI can answer using your internal materials. Tables in PDFs are read as tables.
More use reduces the cost per use
With a one-time purchase, adding apps used across the company reduces the cost per use. Expansion does not create a corresponding usage-charge penalty, excluding electricity and other operating expenses.
The difference between having and not having a store resembles the difference between a shared folder and an internal storefront. A folder reaches people who already know its location. A storefront lets passers-by discover something useful. Whether AI apps become part of company life depends heavily on discoverability, not just performance.
Beyond the store: early apps and collaboration with software vendors
Smartphone stores gained much of their value when outside developers started publishing apps. The GaiXer App Store is moving in the same direction, and early examples are already running.
SOAP Assist / Medical Summary Generation
Healthcare generative AI apps are available from the GaiXer App Store, demonstrating a foundation operating in a field with high security requirements. Their output is drafting support requiring review by healthcare professionals.
Chat, meeting minutes and presentations
Apps are available from the first day of deployment. Behind the meeting-minutes app is a speech transcription engine that runs entirely on the device without internet access, including speaker diarization.
Make an AI-enabled edition practical
The largest barrier has been building and maintaining the AI-OS. On Sovereign GaiXer, you can explore an AI-enabled edition running in customers’ on-premises environments, much as you would publish a smartphone app.
GaiXer App Store: frequently asked questions
What is the GaiXer App Store?
It is a store for distributing business apps internally and choosing which to use. Sovereign GaiXer has four layers: PGX hardware, the Sovereign GaiXer AI-OS, the GaiXer App Store and business apps. The store is the second layer from the top. Employees can obtain the business apps they need much as they install smartphone apps.
How is it different from a smartphone app store?
The main difference is that it is designed for internal use rather than public distribution. Apps run inside PGX without sending internal data to the internet. The smartphone OS and store comparison is an analogy for the product structure, not a claim of compatibility or equivalence with particular OS or store products.
Do I need programming knowledge to build an app?
No. Sovereign GaiXer, the AI-OS, handles difficult tasks such as LLM operation and security. You can build generative AI apps for your workflows and distribute them internally through the GaiXer App Store without programming knowledge.
What apps can I use?
Standard business apps include chat, meeting minutes and presentation creation. Early healthcare apps such as SOAP Assist and Medical Summary Generation are also available through the GaiXer App Store, and you can add apps you develop yourself. Availability and scope may vary by configuration and edition.
Does adding apps increase the price?
Under the Japanese offer, no. Sovereign GaiXer is a one-time purchase of JPY 3,806,400 (JPY 4,187,040 including Japanese tax), with no additional charges for more generations, imported pages or users, excluding operating expenses such as electricity. As internal usage grows, the cost per use falls. Overseas pricing and applicable terms must be confirmed with sales.
Does data leave the company when using store apps?
No. AI processing stays inside the unit, without sending internal data to the internet.
Can we manage who can use the apps?
The AI-OS provides user and login management. The admin console can create and suspend accounts, including bulk CSV registration, separate administrator and ordinary-user permissions, and automatically lock accounts after repeated failed logins. Graphs and CSV exports show usage by person and department.
Can a business software vendor use it to add AI to its products?
Yes—please contact us. Just as smartphone developers can publish apps without building an OS, Sovereign GaiXer handles inference engines and security. Vendors can focus on app development and explore AI-enabled versions running in customers’ on-premises environments. SOAP Assist and Medical Summary Generation are early examples.
Can I use the app store by buying only PGX?
No. PGX includes Ubuntu, a computer OS, but neither the AI-OS for business AI nor the store for app distribution. As explained in Part 1, it is like a smartphone without a phone, camera or app store.
Where should we start evaluating it?
Start with work involving data that cannot leave the company, especially tasks that are daily, high-volume and repetitive. The cost assessment helps estimate costs, while the internal approval kit supports your business case. The kit’s source materials are Japanese; contact sales for overseas requirements.
Three points to understand the GaiXer App Store
- The GaiXer App Store is second from the top in the four-layer structure. It provides distribution within the system for building, distributing and running AI apps, as part of the catalog’s “AI application runtime platform.”
- The AI-OS handles LLM operation, hallucination controls, prompt injection defenses and user management. This means creators can build without IT expertise, while employees simply choose and use apps.
- Under the one-time purchase model, more apps and users do not incur extra usage charges, excluding electricity and other operating expenses. The platform already runs early healthcare apps and is open to collaboration with business software vendors. Overseas commercial conditions require confirmation.
This article reflects the Japanese source and development status as of August 2026. Feature availability and scope may vary by configuration and edition. The smartphone OS and app-store comparison is an analogy for the product structure, not a claim of compatibility or equivalence with specific products. “AI-OS” describes the software foundation for secure business use of AI. The Japanese one-time purchase price is JPY 3,806,400 (JPY 4,187,040 including Japanese tax), with no additional charge based on generations, imported pages or users; electricity and other operating expenses are excluded. Overseas pricing, availability and terms must be confirmed with sales. The comparison with self-built store infrastructure describes a general in-house development scenario, not specific competing products or services. Healthcare app output is drafting support requiring professional review and does not replace diagnosis or treatment decisions. ThinkStation is a Lenovo trademark.
