ArchGPT

What ArchGPT is

ArchGPT turns written descriptions into diagrams for software and systems work. It supports UML, ER, flowchart, C4, sequence, use case, activity, object, state, deployment, component, and system architecture diagrams, including cloud architecture for AWS, GCP, and Azure. Users can upload a diagram image and request changes in plain English while keeping its elements intact. It can also review uploaded UML or architecture diagrams, returning a score, metrics, checklist, issues, recommendations, and a PDF report. From diagrams, it can produce high-level and low-level design documents for DOCX or PDF export. Generated diagrams can be edited in its built-in Draw.io editor, downloaded in PNG, JPEG, SVG, or PDF, and shared by link. The web service has a free plan with 20 credits every 30 days, seven saved diagrams, seven-day history, watermarked PNG exports, and a 500-character prompt limit. Paid plans start at ₹499 per month. The FAQ says prompts can be refined with AI and that diagrams are not used for training or shared.
