A Thorough Comparison of the 4 Major AI Editors, Including the Trending 'Claude Code'—The AI-Driven Development Association to Host 3 Consecutive Free Seminars for Engineers in April

Choosing an AI editor has become a 'religious war'—a topic of such heated debate among engineers that it is whispered about frequently. As of 2026, with the four major tools—Cursor, Claude Code, Antigravity, and Devin—locked in fierce competition, the AI-Driven Development Association is launching a series of three consecutive, practical, and free online seminars, starting with a thorough comparison of these tools.

Background of the Press Release The "AI-Driven Development Association," operated by Cyber Freaks Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Junsuke Tanaka), an educational institution supporting engineers in the practical application of AI, has announced that it will hold three consecutive free online seminars in April 2026. There is a rapidly growing number of engineers and development teams asking, "I want to introduce AI, but I don't know where to start" or "I've tried the tools, but I can't master them." This seminar series provides practical content directly addressing these on-the-ground challenges, completely free of charge. Seminar Overview (3 sessions total, completely free) ■ Session 1: Which AI Editor is Best? The Ultimate Showdown Date/Time: April 3, 2026 (Fri) 19:00~ / Online / Free to attend While Cursor continues to reign supreme, we will thoroughly compare the four major tools—the terminal-based Claude Code, Google's challenger Antigravity, and the fully autonomous Devin—to determine the "ultimate" tool best suited for your development style. ■ Session 2: The Key to AI-Driven Development! Skills and Sub-agents Date/Time: April 6, 2026 (Mon) 19:00~ / Online / Free to attend We will explain the "skills" and "sub-agents" that are crucial for mastering AI agents. Understanding these two concepts will dramatically improve the efficiency of your AI-assisted work and the quality of your deliverables. ■ Session 3: Engineering in the AI Era: Context and Harnesses Date/Time: April 7, 2026 (Tue) 19:00~ / Online / Free to attend What should engineers learn in the age of AI-driven development? We will explain "Context Engineering" and "Harness Engineering." This course is designed to help you evolve from an engineer who uses AI aimlessly into one who can truly master it.
