Frequently asked questions

What is a brand voice AI?

A brand voice AI learns your tone, vocabulary and writing rules once, then writes every piece — SEO articles, social posts, emails, press releases — in that exact voice, instead of generic AI output.

How is Plume different from ChatGPT or Jasper?

Generic AI generates; Plume keeps you on-brand. It injects your brand DNA and active persona into every generation and scores each piece against your voice, so you ship on-brand by default.

How do you measure brand voice consistency?

Plume scores each piece on six dimensions — tone, vocabulary, structure, rhythm and more — against your defined brand voice, giving a 0-100 brand-match score you can set a threshold on.

Can Plume keep multiple brand voices consistent?

Yes. Define multiple voices — a corporate voice for the blog, a founder voice for LinkedIn — and Plume keeps each consistent, and can even pick the right one for the situation.

Does Plume help with GEO and getting cited by ChatGPT or Perplexity?

Plume generates well-structured, on-brand content that AI engines can cite. It helps you produce the consistent, citeable content generative search rewards — in your brand voice.

Which content formats does Plume support?

20+ formats: SEO articles, social posts, newsletters, press releases, ads, pitches, cold emails and more — each generated in your brand voice.
