Brivvy

Brivvy is brand-voice infrastructure that lets a team define how its brand sounds and then enforces that voice everywhere AI is used to write. It is built for marketing, sales, founders and support teams who want every blog post, email, pitch or support reply to sound consistent, instead of each AI tool starting from zero.

A team builds a living brand voice covering tone, rules, glossary and audience context inside Brivvy, then publishes it. Brivvy delivers that voice directly into AI clients through MCP, so writing done in Claude, ChatGPT or another connected tool follows the same rules automatically, with no copy-pasted prompt instructions.

Brivvy organizes voices, templates, audience definitions and a glossary in one workspace, with configurable rules for tone, pronoun use, punctuation and formatting. Templates give every piece of content a starting structure, and a comm can be shared externally as a read-only public link, so people outside the organization see a polished page without workspace access.

Brivvy's Free plan costs $0 and includes unlimited members, 1 voice, 3 templates and an MCP server. The Business plan costs $8 per user per month billed yearly and adds unlimited voices, unlimited templates and admin roles. An Enterprise plan with SAML, SCIM and onboarding support is listed as coming soon, billed annually only.
