frequently asked questions
What is AI voice matching for social media?
Voice matching is an AI system that learns your writing style — sentence length, vocabulary, emoji use, tone, punctuation habits — from your existing posts and applies it to all AI-generated content. The result is captions and posts that sound like you wrote them, not a generic AI.
How does PostAI learn my writing voice?
Connect your social accounts or paste examples of your best posts. PostAI analyzes the patterns — how you open posts, how you structure arguments, what makes your writing distinctive — and builds a voice profile. The more examples you provide, the more accurate the match becomes.
Can I have different voice profiles for different platforms?
Yes. PostAI maintains separate voice profiles per platform, because your LinkedIn voice and your Twitter voice are genuinely different — more formal on LinkedIn, more casual and punchy on X. Each platform's AI output is tuned to the correct register automatically.
