ChatGPT pluginHonest brand critiques
Sigil critiques a company’s brand from its public website and an optional public document. The brand review covers positioning, visual identity, voice, a brand score, and the changes to make first. The plugin returns the critique and a link to the full brand review. It does not design logos, generate brand briefs, or access private company systems.
