Where we start:

  • Millions or 10’s of Millions of lines of code.
  • Critical knowledge locked in the heads of a few people.
  • High-risk modifications.

SOFEEI transforms this whole situation into system-level, AI-powered knowledge while significantly decreasing risk.

What is in a name: SOFEEI = Source Code AI Feeder

SOFEEI = your own AI Chief Architect, Chief Developer and Business Analyst in one

Do these sound familiar?

 

“Only a few developers really understand this…”

“We’d rather not touch it – we don’t fully understand it…”

“We don’t know what will happen if we modify it…”

Most legacy systems are:

  • underdocumented

  • hard to understand

  • slow to change

And what about popular AI tools like VS Code AI plugins or Project Bob?

They suite some tasks but they do not provide a solution for the above. They do not understand the system as a whole. They only see individual files, or a few files at a time. They do not understand business and system architecture.

How is SOFEEI different from a typical coding AI agent?

SOFEEI does not just understand code – it understands the entire system

Connections

It connects code, databases, business logic, and documentation.

Scale

It can handle systems with 10’s of millions of lines of code as a whole.

Intelligence

It represents an AI-queryable knowledge base.

SOFEEI doesn’t just answer. It understands. Deeply.

What does what

Where it happens

How everything is connected and why

Automated Documentation

1.Functional descriptions

2.Technical documentation

3.Impact analysis

Safe Development

1.Predict impact of changes

2.Multi-file modifications

Instant System Insight

1.Understand complex systems instantly

2.Navigate millions of lines of code

How it works?

  • 1.

    It continuously ingests the entire codebase and documentation – not just once.

  • 2.

    It connects to your version control systems and other sources of code, documentation, and business rules. It is always up to date.

    2.

  • 3.

    It builds and continuously updates a semantic representation of the system

  • 4.

    It makes the semantic data AI-queryable – both from code to text and from text to code.

    4.

  • 5.

    It can be used directly from VS Code. Works with any AI model. Available in the cloud and on-premise.
