Indian GM Vidit Gujrathi developed two web applications dedicated to improving chess skills. Vidit shared the news about the release on his X account. Gujrathi noted that he ‘vibe-coded’ these websites, using Codex and Opus.

Vibe-coding is an AI-driven software development approach, popularized in early 2025. Developers use natural language prompts to have AI generate applications, shifting focus from writing syntax to guiding functionality.

“Tactics” — is a collection of puzzles consisting of critical positions extracted from GM’s games from Chess World Cup 2025 and XTX Markets London Chess Classic 2025. The puzzles are divided into 4 categories: Critical Moments, Pure Tactics, Defensive Resources and Opening Precision. The web application features an interactive board, Engine Evaluation tab, Hint and Answer buttons, and information about the players who played this position.

“Memory” — is a memory trainer where you memorize a chess position within a time limit and then reconstruct it. The trainer includes 3 difficulty levels with a set number of pieces in the position: Easy (3-6), Medium (7-14) and Hard (15-32). After submitting the reconstructed position, the result with detailed analysis is displayed.

Indian GM Vidit Gujrathi (2708) is a World No. 29 and India’s No. 6. Vidit debuted in the 2024 Candidates in Toronto finishing in 6th out of 8 with a score of 6/14. At the Chess World Cup 2025 Gujrathi was eliminated in the 3rd round after losing a tie-break to American GM Sam Shankland. Vidit announced in December 2025 that he would be stepping back from professional chess temporarily to address ‘burnout’.
