When everything depends on someone else
- Operations tied to third-party services
- Data and context scattered across platforms
- Costs and conditions that are hard to predict
- Expertise that disappears with access
AI continuity under your control
If AI stopped tomorrow, would your company keep working?
T-Chat brings AI, documents and automation into an environment you control. It adapts to your organisation, including fully offline environments, with online services only when you choose them.
- Data control
- Operational resilience
- Human oversight

Continuity is not a backup. It is the ability to keep moving.
Your AI workspace, always within reach
On your Mac. On your phone.
Under your control.
Work with T-Chat on your Mac and continue on your phone with Nearby, on the same private network. Chats, projects and tools stay in your environment, without exposing the service to the Internet.

The invisible risk
AI is already inside your processes. Control is still outside the company.
An outage, a policy change or revoked access can halt knowledge, automation and decisions. Going backwards is not a plan.
When intelligence stays with you
- AI capabilities available within your perimeter
- Organised, reusable business knowledge
- Governed, verifiable and transferable processes
- Freedom to choose models and services
One platform, many capabilities
More than a chat.
A complete place to work.
T-Chat connects models, people, documents and tools. Start with one useful process and add more when the business is ready.
GOVERNED AUTOMATION
Work keeps moving. You keep control.
Recurring schedules and operational agents execute tasks, prepare outcomes and respect the level of autonomy your company has chosen.
BUSINESS KNOWLEDGE
Documents and folders become operational context.
Information remains organised, searchable and usable in projects without losing the connection to its sources.
COMPOSABLE EXPERTISE
Bring different perspectives around the same goal.
Personalities, missions and AI meetings help assess scenarios, create plans and challenge decisions.
MULTIMODAL CREATION
From reasoning to content in the same flow.
Text, documents, images, video and audio become part of one process, configured around your needs.
PROJECTS AND APPLICATIONS
Turn an idea into a real workspace.
Dedicated workspaces, files, tools and applications stay connected to the project. AI does more than suggest: it works inside the authorised perimeter and makes its actions visible.
MODEL FREEDOM
Your strategy does not depend on one provider.
Open models, local capabilities and enabled online services work together based on priorities, performance and data sensitivity.

Hardware roadmap
Apple Silicon today.
NVIDIA and AMD in development.
We are developing T-Chat versions for NVIDIA and AMD hardware, extending choice beyond Apple Silicon. They are not available yet: supported operating systems, cards, requirements and release dates will be announced after validation.
The current edition remains designed for Apple Silicon Macs. Memory and model choices should be sized for the actual workload.

From one Mac to a whole team
The right hardware depends on the work, not the trend.
An Apple silicon Mac and a small model may be enough to begin. More memory supports larger models, longer contexts and more work at once. SSD Streaming lets selected MoE models reach beyond the available RAM.

Frequently asked questions
Before you begin.
Do TChat, T Chat and T-Chat refer to the same product?
Yes. T-Chat is the official name of HalloCorp's local and hybrid AI platform for business on Mac. “TChat” and “T Chat” are common search variations.
Does T-Chat replace the AI tools we already use?
Not necessarily. It can complement them, orchestrate enabled alternatives and create an independent operational perimeter for the processes that cannot stop.
Does T-Chat also work in fully offline organisations?
Yes. T-Chat adapts to independent professionals, teams and businesses, including organisations with fully offline infrastructure. With local models and tools already installed, you can work without an Internet connection. If you want to integrate online services, you choose which ones to enable: they are not required to use local capabilities.
How is agent autonomy managed?
Your organisation defines permissions, approvals, limits and accountability. Actions remain visible, and human oversight can be stricter or lighter depending on the process.
Where should we start?
Start with one or two high-value use cases where risk can be controlled. The initial assessment identifies a concrete, measurable perimeter that can grow over time.
Is there a path for teams and partners?
Yes. Configurations, expertise and operational packages can be prepared for organisations, professionals and partner networks.
