Factual comparison — May 2026
GPTPowerUps vs ChatGPT Toolbox
ChatGPT Toolbox launched September 2024, claims 18,000+ active users, and has built a 270-page SEO content hub. It works on ChatGPT only — Claude requires a separate install, Gemini a third install. Firefox is not supported. GPTPowerUps covers all three AI hosts in one install, including Firefox.
About ChatGPT Toolbox
ChatGPT Toolbox (developed by Infi Developments) focuses on conversation organization: folders, subfolders, pinning, full-text search, export, and bulk actions. It has built a 270-page SEO content machine to drive organic traffic — including a /compare hub, use case pages, and competitor comparison articles. The developer's strategy is to build a separate Toolbox for each AI host: ChatGPT Toolbox, Claude Toolbox, Gemini Toolbox — each a distinct install and distinct subscription. That means a user who works across ChatGPT and Claude pays twice and manages two separate extensions. GPTPowerUps unifies those three hosts in one extension and one pricing tier.
