When to pick Zebrafy
- Built generation-first, not grammar-first — Zebrafy produces on-brand content, not just corrects existing text.
- Persistent Brand DNA profile captures your real voice. Grammarly has a 'tone detector' and style guides but no structured voice profile.
- Free forever plan (Colt) with 10 generations and 10 scores per month.
- Platform-aware Chrome extension — writes directly on LinkedIn, Instagram, Google Reviews, etc. Grammarly edits text you've already written.
- On-Brand Score (1–100) rates any text against your Brand DNA.
When to pick Grammarly
- Best-in-class grammar, spelling, and style correction — Zebrafy does not replace that.
- Native integrations across Word, Google Docs, Outlook, and every major browser.
- Business plan style guides and brand tones for company-wide writing consistency.
Frequently asked questions
- Is Zebrafy a Grammarly alternative?
- Not exactly — they solve different problems. Grammarly is a grammar and style corrector; Zebrafy is an on-brand content generator. Most teams run them together: write with Zebrafy in your Brand DNA voice, then let Grammarly catch typos and grammar issues. Think of Zebrafy as the author and Grammarly as the copy editor.
- Does Zebrafy check grammar like Grammarly?
- No — Zebrafy does not compete with Grammarly on grammar or spelling correction. Zebrafy focuses on voice, brand, and platform adaptation. If you need grammar checking, keep Grammarly installed alongside Zebrafy.
- Is GrammarlyGO as good as Zebrafy for brand voice?
- GrammarlyGO is strong at generic writing assistance (rewrites, tone shifts, replies). Zebrafy is specifically architected around a persistent Brand DNA profile that constrains every generation to your voice — that's the key difference. If brand voice consistency is the goal, Zebrafy is purpose-built for it.
- Can I use Zebrafy and Grammarly together?
- Yes, that's the recommended pairing. Both Chrome extensions coexist fine on the same page. Generate in Zebrafy for brand-voice content and let Grammarly polish grammar and spelling.
