Overview

What it is

BELA Engineering Knowledge understands your business, code, repositories, legacy systems, APIs, databases and documents — and turns them into complete, living engineering knowledge. It writes the BRDs, PRDs, SRSs, architecture and API documentation, guides, decision logs and the engineering timeline, and keeps them current as the system evolves. Upload what you already have, and BELA understands it and fills the gaps.

Benefits

Why it matters to your business

Knowledge that writes itself

BRDs, PRDs, SRSs, architecture and API docs, guides and decision logs — generated from the real engineering, not typed by hand.

Understand what you already have

Upload a repository, legacy app, API or database and BELA reads it — so nothing is a black box.

It never goes stale

Documentation is a projection of the system, so it evolves as the system does. No more docs that lie.

A new engineer onboards unaided

The reasoning behind every decision is written down, so people understand the system without asking anyone.

Features

What it does

Automatic documentation

BRD, PRD, SRS, architecture documents, user, admin and deployment guides — generated and kept current.

API documentation

Complete, accurate API docs derived from the real interface, not hand-maintained.

Understand existing systems

Upload repositories, source code, legacy apps, APIs, databases and documents — BELA reads and models them.

Engineering Passport

A portable, verifiable record of a project's engineering — what it is and why.

Decision logs & timeline

Every decision, trade-off and limitation, preserved with the reason and the moment it happened.

Evidence explorer

Trace any part of the system back to the evidence and reasoning that produced it.

Workflow

How it works, end to end

01
Ingest
Point BELA at your business, code, repos, APIs, databases or docs.
02
Understand
It reads and models them into structured engineering knowledge.
03
Document
It writes the BRDs, architecture, API docs, guides and decision logs.
04
Preserve
Everything is stored, connected and searchable.
05
Evolve
As the system changes, the knowledge updates with it.
Inputs

What you give it

  • A business description, or existing repositories, source code, legacy apps, APIs, databases, documents, specifications, OpenAPI or architecture diagrams
Outputs

What you get back

  • BRD, PRD, SRS
  • Architecture and API documentation
  • User, admin and deployment guides
  • Decision logs and an engineering timeline
  • An Engineering Passport
Example

A real business, understood

You describeUpload a legacy codebase no one on the team fully understands.
BELA deliversBELA reads the repository, models its entities, operations and dependencies, writes the architecture and API documentation, and produces a decision log and timeline — so the team finally understands what they inherited.
Three views, one project

Business, architecture and engineering

Business view

What the system does, in plain business language.

Architecture view

Modules, boundaries, dependencies and decisions.

Engineering view

The entities, operations, APIs and the evidence behind them.

Qualification

Every build is proven

Knowledge is a projection of the real engineering, verified against it — so it cannot drift from the system it describes.

Security

Safe by default

Your knowledge is tenant-isolated and access-controlled. Deterministic and AI-independent: understanding does not depend on an external model.

FAQ

Questions, answered plainly

Can it understand my existing code and legacy systems?
Yes. Upload repositories, source code, legacy apps, APIs, databases or documents and BELA reads and models them.
Will the documentation stay up to date?
Yes — it is a projection of the system, so it evolves as the system does, rather than drifting out of date.
Is this just a documentation tool?
No. It understands the business and the engineering, preserves the reasoning, and evolves the knowledge — documentation is one output.
What formats can I export?
Documents and diagrams in the formats teams use — including Word, PDF, OpenAPI, SQL and diagram formats.
