Frequently Asked Questions

Everything you need to know about PersonaBox

Have questions about how PersonaBox works? Here are the answers to the most common questions we receive.

How does PersonaBox analyze my content?

PersonaBox uses AI to evaluate your writing against your messaging and brand guidelines. It analyzes tone, messaging alignment, technical depth, and audience resonance to provide real-time feedback and actionable suggestions.

What platforms does the Chrome extension work with?

Our extension works seamlessly with Google Docs, Gmail, LinkedIn, Twitter, Notion, and most web-based writing platforms. It provides instant feedback without disrupting your workflow.

How do I create messaging or personas if I don't have any?

PersonaBox offers AI to help you create your own personas and messaging. If you need help, PersonaBox's product marketer in-residence can help you build messaging and personas from scratch using our guided setup process.

Why should I use PersonaBox if we already have a custom GPT, Claude Project, Notebook LM, or Google Gem?

PersonaBox isn't a replacement for your custom LLM instances—it's built to work alongside them. Teams that already have a custom LLM with all of their messaging use PersonaBox for two key reasons: First, it works as a final check layer purely focused on messaging alignment. You can even copy the analysis into your LLM to iterate based on the feedback. Second, it works where your go-to-market team already works. For example, as a Chrome extension, account executives can quickly get feedback and improve their emails before sending—no context switching required.
