AI That Writes in Your Voice, Not a Generic One
Most AI writing tools produce generic output that sounds like every other brand. Postprism's Brand Voice AI lets you define your tone, vocabulary, and style, so every adapted post reflects your authentic voice across every platform.
Everything you need
Every feature is designed around saving you time while improving your results.
Tone and style configuration
Define your brand voice with descriptors, direct, conversational, authoritative, warm, technical, or a custom combination. The AI uses these parameters to shape the register and word choice in every generated piece.
Vocabulary rules and guardrails
Specify words or phrases to always use (your brand terminology, product names, taglines) and words to always avoid (competitor names, off-brand language, industry jargon). The AI follows these rules in every output.
Sample post training
Provide examples of your best existing posts. The AI analyzes your sentence structure, rhythm, and characteristic expressions and replicates them in new content. The more examples you provide, the more accurate the voice matching.
Personal brand support
For founders, creators, and solo professionals, brand voice can be configured to match individual writing style rather than corporate messaging. This is particularly valuable for building in public on LinkedIn and Twitter/X.
Per-platform voice fine-tuning
Your brand voice can have a consistent core with platform-specific adjustments. You might be slightly more casual on Twitter/X and more formal on LinkedIn, both reflecting the same underlying brand personality.
