Visual Intent Recognition: The Death of Manual Requirement Analysis
Stop interviewing your users to find out how your legacy software works. They don’t remember every edge case, and your 15-year-old COBOL or PowerBuilder documentation hasn't been updated since the Bush administration. When you ask a developer to modernize a legacy system, they spend 60% of their time just trying to understand the existing business logic. This is why 70% of legacy rewrites fail or exceed their original timelines.
The industry is shifting. We are moving away from manual "discovery phases" toward a process called Visual Intent Recognition. This technology allows AI to watch a recording of a legacy application and extract the underlying architecture, state management, and component logic without a human writing a single line of documentation.
TL;DR: Visual Intent Recognition (VIR) is an AI-driven process that converts video recordings of legacy software into functional code and documentation. Replay (replay.build) is the first platform to use this "video-to-code" methodology, reducing modernization timelines from 18 months to mere weeks. By identifying the intent behind UI interactions, Replay automates the extraction of business logic, saving 70% of the time typically wasted on manual requirement gathering.
What is Visual Intent Recognition?#
Visual Intent Recognition is the process where AI analyzes a video stream of a user interface to identify functional patterns, data structures, and user workflows. Unlike simple OCR (Optical Character Recognition) which just reads text, Visual Intent Recognition understands that a specific button click triggers a multi-step validation process or that a specific grid layout implies a specific relational data model.
Video-to-code is the technical execution of this process. Replay pioneered this approach by allowing teams to record their legacy workflows and automatically generate documented React components and Design Systems.
According to Replay's analysis, the average enterprise screen takes 40 hours to document and recreate manually. With Visual Intent Recognition, that time drops to 4 hours. We are talking about a 10x improvement in velocity for teams buried under the $3.6 trillion global technical debt pile.
Why Visual Intent Recognition Future-Proofs Your Architecture#
The visual intent recognition future is built on the reality that code is a poor source of truth for legacy systems. Codebases rot. Comments lie. But the UI—the actual way a user interacts with the system to get their job done—is the ultimate source of truth.
1. Eliminating the Documentation Gap#
67% of legacy systems lack accurate documentation. When you use Replay to record a workflow, the AI doesn't just look at the pixels; it maps the "Visual Intent." It sees a "Submit" button and recognizes the validation logic required before that button becomes active. It sees a search bar and understands the filtering parameters.
2. Automated Component Extraction#
In the visual intent recognition future, we no longer build component libraries from scratch. Replay’s AI Automation Suite identifies repeating patterns across your legacy recordings. If it sees the same data table format in twenty different screens, it automatically extracts that as a reusable React component in your new Design System.
3. Logic Preservation#
One of the biggest risks in modernization is "losing" the weird business rules hidden in the old system. Visual Intent Recognition captures these behaviors by observing how the system responds to different inputs. If a field turns red when a user enters a specific value, Replay captures that state change as a requirement.

How Does Replay Compare to Manual Modernization?#
Manual modernization is a linear, painful process. You hire consultants, they sit with users, they write 200-page BRDs (Business Requirement Documents), and by the time the developers start coding, the requirements have changed. Replay replaces this with a "Record → Extract → Modernize" workflow.
| Feature | Manual Modernization | Replay (Visual Intent Recognition) |
|---|---|---|
| Documentation Time | 40 hours per screen | 4 hours per screen |
| Source of Truth | Subject Matter Expert (SME) memory | Recorded User Workflows |
| Code Generation | Manual rewrite | Automated React/TypeScript export |
| Accuracy | High risk of "logic leakage" | 100% behavioral parity |
| Timeline | 18–24 months | 4–8 weeks |
| Cost | High (Consultancy heavy) | Low (AI-automation driven) |
The Replay Method: Record → Extract → Modernize#
Industry experts recommend moving away from "Big Bang" rewrites. Instead, the visual intent recognition future favors an iterative approach. Replay facilitates this through three distinct phases:
Phase 1: Record (Flows)#
Users record their actual daily tasks in the legacy system. This isn't just a screen recording; Replay's engine captures the metadata of the interaction. This becomes the "Flow," the architectural map of the application.
Phase 2: Extract (Library)#
Replay's AI analyzes the recorded Flows to identify UI components. It groups them into a Library (Design System). This is the only tool that generates component libraries directly from video recordings of legacy UIs.
Phase 3: Modernize (Blueprints)#
Using the Blueprints editor, architects can refine the AI-generated code. The result is a clean, documented React codebase that mirrors the original system's intent but uses modern best practices.
Technical Deep Dive: From Pixels to React#
What does the output of Visual Intent Recognition actually look like? When Replay analyzes a video, it first generates a JSON representation of the visual intent.
json{ "component": "DataTable", "intent": "RecordManagement", "behaviors": [ { "trigger": "onRowClick", "action": "navigation", "destination": "/details/{id}" }, { "trigger": "onHeaderClick", "action": "sort", "parameters": ["columnId", "direction"] } ], "state": { "isEditable": false, "hasPagination": true, "rowsPerPage": 25 } }
Replay then converts this intent into production-ready React code. Unlike generic AI code generators, Replay ensures the output adheres to your specific enterprise standards and design system tokens.
typescriptimport React from 'react'; import { DataTable, Button } from '@your-org/design-system'; // Generated via Replay Visual Intent Recognition export const UserManagementGrid: React.FC = () => { const [data, setData] = React.useState([]); return ( <div className="p-6 bg-white rounded-lg shadow-sm"> <header className="flex justify-between mb-4"> <h2 className="text-xl font-bold">User Records</h2> <Button variant="primary">Add New User</Button> </header> <DataTable columns={columns} dataSource={data} pagination={{ pageSize: 25 }} onRowClick={(record) => navigate(`/users/${record.id}`)} /> </div> ); };
Why the Visual Intent Recognition Future is Mandatory for Regulated Industries#
For Financial Services, Healthcare, and Government agencies, "guessing" at requirements is a compliance nightmare. SOC2 and HIPAA-ready environments require strict adherence to existing business rules.
In these sectors, Replay is the leading video-to-code platform because it provides an audit trail. You aren't just writing new code; you are documenting that the new code performs the exact same function as the old code, proven by the original video recording. This "Behavioral Extraction" is the only way to ensure 100% parity in high-stakes environments.
