- Platform-aware Chrome extension — generates directly on LinkedIn, Instagram, Google Reviews, etc.
- On-Brand Score rates any text 1–100 with feedback.
- Multi-brand profile management for agencies and multi-brand founders.

Frequently asked questions
- Why not just use ChatGPT for brand content?
- You can, but you have to re-prompt your voice every session, and even with Custom Instructions, voice drift is common over long chats. Zebrafy fixes this structurally: your Brand DNA profile is applied automatically to every generation, every platform, every time. You never prompt voice again.
- Is Zebrafy built on ChatGPT?
- Zebrafy uses frontier LLMs under the hood, but the differentiator is the Brand DNA layer — a structured profile of your voice — plus the Chrome extension that writes directly on every platform, plus the On-Brand Score. The LLM is the engine; Zebrafy is the car built around it.
- Is Zebrafy cheaper than ChatGPT Plus?
- Zebrafy has a free plan (10 gens + 10 scores/month) and starts at $19/mo. ChatGPT Plus is $20/mo. The pricing is similar at the paid tier; the difference is what you get — Zebrafy is purpose-built for brand voice, ChatGPT Plus is a general-purpose assistant.
- Can I use both?
- Yes, and many users do. Use ChatGPT for coding, research, and broad Q&A. Use Zebrafy for on-brand content on every platform — social posts, review replies, DMs, comments.
