Ask FirstNet about Sovereign AI
Custom AI Engineering
Infrastructure alone does not fix a business problem. EngineAI is FirstCoreAI's build team: they take a use case from proof of concept to production, deployed on the AI Factory in FirstNet's data centre or inside your own environment.
Case in point
965 call recordings, made searchable
For a national insurer, EngineAI built a pipeline that turned 965 call recordings into structured, searchable data. The work covered transcription, correction and name resolution, ending in clean JSON the business could use. It ran on sovereign infrastructure, so no recording ever left South Africa.
- Transcription and correction of every recording
- Name resolution across calls
- Structured JSON output for downstream systems
- Processed entirely on local infrastructure
What we build
EngineAI capabilities
RAG and retrieval
Make your documents, contracts and internal knowledge searchable and answerable in plain language.
Document and call pipelines
Intake, extraction, transcription and structured output for large volumes of files and recordings.
Autonomous agents
Multi-step workflows that approve, route, tag and report without a person at every step.
Fine-tuning and optimisation
Models adapted to your domain, your terminology and your own data.
Integration
Connections into Microsoft 365, your CRM and other line-of-business systems.
How it fits together
Engineering on a sovereign backbone
Most EngineAI projects run on InfraAI compute, so models, data and pipelines stay in FirstNet's South African data centre. Where it makes more sense, solutions can be deployed into your own environment instead.
- Build on the AI Factory or in your environment
- Open-weight models by default, frontier APIs where justified
- Honest advice if AI is not the right tool
Get started
Bring us a problem
Start with the business problem, not the technology. FirstCoreAI will scope what a working solution looks like and say so plainly if AI is not the answer. Book a scoping call or demo with FirstCoreAI to begin.
What kind of AI solutions does EngineAI build?
RAG and retrieval systems, document and call-processing pipelines, autonomous agents, fine-tuned models and integrations into Microsoft 365, CRMs and line-of-business systems.
Where are the solutions deployed?
Either on FirstCoreAI's AI Factory in FirstNet's South African data centre, or into your own environment, depending on what suits the workload.
Can you process call recordings without sending them offshore?
Yes. For a national insurer, EngineAI processed 965 call recordings into structured, searchable data on sovereign infrastructure, so no recording left the country.
Can a model be tuned to our industry terminology?
Yes. Fine-tuning and model optimisation adapt models to your domain, terminology and data.
What if AI isn't the right fit for our problem?
FirstCoreAI scopes each problem first and will tell you honestly if AI is not the right tool.
