Brand voice AI: every caption, post and hook in your own tone

The problem with "AI-generated" captions

Everyone can tell. The same enthusiasm, the same three emojis, the same "Ready to level up?" close. When an account that used to sound like a person starts sounding like a template, engagement drops — followers came for the person. The value of AI writing is speed; the cost, without a voice, is trust.

A brand voice model fixes the cost without giving up the speed. Splicora reads what you have already written and derives a profile: how formal you are, how long your sentences run, whether you open with a question or a statement, which words are yours and which you would never use. Every generated caption is then written against that profile. Read how brand voice AI keeps captions sounding like you for a worked example.

What a profile captures

• Register — casual, direct, technical, warm. Most brands sit in one place on that scale and rarely move.
• Rhythm — short punchy lines or longer, explanatory ones; one idea per sentence or several.
• Vocabulary — the words you use for your product, your audience and your ideas; the words you avoid.
• Structure — how you open, whether you use lists, how you close, whether you ask for the follow.
• Guardrails — claims you never make, topics you do not touch, emoji policy.

The profile is shown as a plain-language list of rules, not a black box. If the AI gets something wrong, you change the rule rather than fighting the output.

For agencies and teams

A team managing several accounts needs several voices and a way to keep them apart. Profiles are selected per project, so a clip repurposed for one client is never captioned in another client's tone. Plans scale with that: one voice on Free, three on Starter, ten on Pro and twenty-five on Teams, with team seats on the Teams plan so writers and editors share the same profiles. Combine it with caption presets and the brand kit and every output — text and picture — is on brand by default.

Brand voice across the product

The profile is used wherever Splicora writes: the on-screen text around captions, the openers from the hook generator, the titles and descriptions attached to a scheduled post, and the blog posts, newsletters and threads produced in a project's Write stage. The faceless video generator writes its scripts in it too.
