Custom software for businesses
Platforms and applications built to last, integrate with what you already run, and stay maintainable. Less guesswork, more decisions grounded in evidence.
Software that must hold when it has to be proven.
Devisia designs digital systems for organisations that cannot afford black boxes: platforms, governed AI and operational compliance where data, processes, accountability and evidence stay readable.
If the process is fragile, automation makes it faster
Technology does not rescue an opaque flow. When roles, data and constraints are explicit, custom software development and AI integration increase quality, control and operational capacity.
Three domains, one governable system
We do not ship disconnected modules. A useful system connects custom software for businesses, governed AI and operational proof.
AI for businesses
Assistants, RAG, agents and workflows only where there is a control model: boundaries, logging, validation, human oversight and clear accountability.
Operational compliance
Not a pile of policies, but the ongoing ability to show what was done, by whom, when and with which evidence.
From real work to verifiable proof
This is not a checklist. It is a chain of control: understand where risk begins, design the boundaries, and make each decision readable when it needs to be evidenced.
Process before technology
We interview operators, exceptions and unwritten rules before choosing interfaces, automations or AI components.
Models inside clear boundaries
A production AI system needs limits, logs, validation, policy, oversight and human accountability.
Intentions are not evidence
GDPR, NIS2, DORA and ISO 27001 become sustainable when every control produces readable proof.
Devisia Chat
Ask the site. Get answers you can verify.
Grounded answers, visible boundaries, no black box.
A guided assistant helps you explore services, method and AI governance without hunting through every page. It answers only from public Devisia content and makes the technical perimeter visible: exported Markdown, indexed knowledge, Toolhouse orchestration and server guardrails.
- Markdown source
- Server-side proxy
- Public perimeter
Open a dedicated page for longer questions, or use the floating assistant while browsing.
-
Readable knowledge
Public pages are exported to clean Markdown with frontmatter, so every answer starts from content that is readable, versionable and traceable.
-
Search-ready ingestion
The exported content is split into retrieval chunks, letting the assistant select relevant passages before composing a reply.
-
Toolhouse, behind a proxy
Requests pass through `/api/toolhouse-chat`: Toolhouse handles the agent flow, while credentials stay server side.
-
Guardrails by design
The chat keeps to public content, sanitises Markdown output and avoids collecting secrets or private operational data.
AuditReady: when control becomes proof
Collect, organise, validate and export evidence for audits, compliance and security. AI-assisted where it helps, human control always. It is how we turn method and governance into an operational product.
Explore AuditReadyLess noise. More structure
- We start from process, not from a technology catalogue.
- We make constraints, data, roles and accountability explicit.
- We build readable, traceable software.
- We treat AI and compliance as architectural decisions, not add-ons.
- We favour controlled releases and verifiable evidence.
If the system must hold, we start from what it must prove
Share process, data, risk, constraints and people involved. The first goal is to align context, boundaries and success criteria, not to sell a ready-made bundle.
