Three Cores

Every AI application needs three things done right. We made them first-class citizens.

Intelligence

Memory

Your data, your rules. Full CRUD, one-click export, real deletion. Event-sourced history. Runs on your infrastructure with complete data sovereignty.

Billing

Hard budget limits. Pre-debit token reservation. No surprise costs. Complete audit trail per agent, workflow, and user.

The Platform

A deterministic foundation with AI as a managed tenant, not the other way around.

Architecture

Microservice-based. Each service is independently deployable. Schema-validated inputs and outputs. Event-sourced state. ACID guarantees.

Deployment

Self-hosted via Docker Compose. Runs on any Linux VPS. 30+ containers orchestrated. Cloudflare Tunnel for secure access.

Open-Source-Based

Built entirely on proven open-source technology. No proprietary black boxes in the stack. Vendor-independent by design.

Principles

01

Data Sovereignty

Full export, real deletion, audit trails. Your data never leaves your control. GDPR-compliant by design, not by afterthought.

02

Cost Transparency

Every token is accounted for. Pre-debit ensures you never exceed your budget. Exact cost attribution per operation.

03

Vendor Independence

LLM, storage, auth: all swappable. No single provider dependency. Your application survives any vendor decision.

04

Deterministic Foundation

AI operates within deterministic rules. Schema-validated, event-sourced, ACID-backed. Predictable behavior, auditable outcomes.

Solutions

How organisations can use 3cors to bring AI into their business. Safely and on their own terms.

01

Intelligent Document Processing

Turn unstructured information (contracts, manuals, reports) into structured, searchable knowledge. Ask questions in natural language and get relevant answers from your own data.

Key benefit: Sensitive documents can remain on your own servers. No data needs to leave your organisation.
02

AI for Regulated Industries

Finance, insurance, healthcare, and public sector organisations often cannot use cloud-based AI services. 3cors is designed to run on your own infrastructure, helping you meet regulatory requirements.

Key benefit: Designed with European data protection regulations in mind. Full audit trails for every operation.
03

AI Cost Management

Many organisations struggle with unpredictable AI costs. 3cors provides built-in budget controls that help prevent unexpected charges, with clear reporting on what each task costs.

Key benefit: Set budget limits per team or project. Costs are reserved before each operation runs.
04

AI Evaluation & Prototyping

Explore different AI approaches without committing to a single provider. Compare results, switch between providers at any time, and find the right fit for your use case.

Key benefit: No long-term commitments. Switch or combine AI providers as your needs evolve.
05

AI Backend for Software Providers

Software companies looking to add AI capabilities to their products can use 3cors as a backend layer. It handles user management, billing, and AI integration so they can focus on their core product.

Key benefit: Core infrastructure is ready to use, allowing faster time to market for AI-powered features.

Every organisation has different needs. Get in touch to discuss how 3cors can support your specific requirements.
