ArchGPT review
A low-cost web tool for generating and refining UML and cloud architecture diagrams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ArchGPT is a browser-based AI diagram generator for developers, architects, engineering teams, students, and technical writers. Users describe systems, processes, databases, or cloud infrastructure in plain English, then receive UML, C4, ER, sequence, flowchart, architecture, and related diagrams. The product also includes AI prompt refinement, plain-English diagram explanations, unique-link sharing, and a built-in Draw.io editor for further changes. Its focus is practical technical visualization rather than general-purpose image creation.
The Free plan costs INR 0 forever and includes 20 credits every 30 days, 7-day history retention, 7 saved diagrams, PNG downloads, watermarked exports, and unlimited sharing. Basic costs INR 499 per 30 days and adds 150 credits, 15-day history retention, 15 saved diagrams, PNG and JPEG downloads, watermark-free exports, and DOCX and PDF export. Pro costs INR 1199 per 30 days, raising the allowance to 600 credits, extending history retention to 90 days, supporting 60 saved diagrams, adding SVG downloads, and including a priority queue. The credit-based structure makes plan selection important for regular generation.
ArchGPT fits teams and individuals who need editable technical diagrams, especially when cloud architecture coverage and low entry pricing matter. Draw.io editing supports post-generation refinement, while explanations and document exports can help communicate designs beyond the diagram itself. The main trade-offs are its web-only platform, limited saved-diagram capacity on Free and Basic, and watermarked Free exports. Buyers who need broader collaboration software, desktop access, or more predictable diagram volume should compare alternatives; those seeking affordable UML, infrastructure, and process diagrams with flexible export options should consider ArchGPT.
