The SI Challenge
Modernization and legacy projects are complex, labor-intensive, and margin-eroding.
⚠️ Margins at Risk
Scarce Legacy Talent
Finding experienced COBOL, Oracle Forms, or Mainframe developers drives costs sky-high and delays projects
📈 30% More Margins
AI Acts as Legacy Expert
Replai's AI becomes your legacy expert, enabling junior developers to work effectively on complex legacy systems
How Replai Changes the Game
Our semantic knowledge layer transforms how you understand and work with legacy systems
Semantic Knowledge Layer
Our AI doesn't just read code - it creates a semantic understanding of your entire system, capturing business logic, relationships, and intent that traditional tools miss.
AI Assisted Development
Create new workflows, extend and modernize legacy - keeping high reliability using Prompt-to-Code.
Faster Delivery
Accelerate project timelines and deliver value to customers faster with AI-powered code generation and automated testing.
Why Replai is Different
Not another black box translation tool
Black Box Translation
Traditional automated tools translate code line by line, creating brittle, unmaintainable output that nobody understands.
- Direct code translation without understanding
- Locked into specific target technology
- Technical debt transferred, not eliminated
- Failed migrations and wasted investments
Recovering Lost Metadata
Replai goes far beyond system modeling - we recover the lost metadata that decades of changes buried. We reconstruct business rules, workflows, and intent into a semantic knowledge layer.
- Recover decades of lost documentation and business knowledge
- Rebuild in any architecture or technology stack
- Create semantic understanding that enables true modernization
- Future-proof migrations that actually succeed
The Game-Changing Difference
By recovering lost metadata and building a semantic knowledge layer, we transform buried business logic into prompts that describe how and what the system does. This enables us to rebuild it in any architecture and any technology - giving you flexibility, quality, and future-proofing that black box tools simply cannot deliver.
Better Together
Unlock the value of working together
Our Agentic AI platform ingests and interprets billions of lines of COBOL, Oracle Forms, PowerBuilder, Mainframe, and other legacy code, transforming them into an AI-accessible knowledge base.
This enables streamlined delivery across every phase - from discovery and estimation to execution and ongoing maintenance - eliminating manual grind and turning modernization into a scalable, high-margin business.
What This Looks Like on a Real Project
A team of four developers takes on an Oracle Forms migration. In week one, they point Replai at the existing codebase. The platform's semantic knowledge layer maps every form, trigger, and business rule - producing the kind of system understanding that would normally take weeks of manual code reading. The team knows exactly what they're dealing with before writing a single line of new code.
By week three, they're using Replai's AI-assisted development to extend functionality in the target architecture, with the recovered business logic guiding each prompt. Hidden dependencies are already documented. Scope surprises don't materialize.
The first milestone ships ahead of schedule. The client sees working software earlier than expected. The SI protects its margins because the team stayed lean and the estimate held.
