Setting up a voice profile

A voice profile trains the AI on how you actually write. The difference between posts that sound like you and posts that sound like generic AI is almost always in how well this profile is set up.

Steps

  1. 1

    Go to Settings → Voice Profiles

    From the dashboard, click Settings and open the Voice Profiles tab. Click New Profile.

  2. 2

    Paste three to five example posts

    Choose posts that genuinely sound like you at your best. Your own LinkedIn posts work well. If you have no posts yet, paste extracts from emails, internal memos, or podcast transcripts.

  3. 3

    Describe the tone

    One or two sentences. Examples: 'Direct, technical, dry humour.' or 'Warm, story-led, lightly self-deprecating.' The model uses this as an explicit instruction.

  4. 4

    List topics you typically cover

    Five to ten recurring themes. The AI uses these to check that generated topics sound like you — not to constrain what you can post about.

  5. 5

    Add hard rules

    Words you never use, hashtag preferences, whether you use emojis. These rules are applied every time the model writes.

  6. 6

    Save and test

    Generate a draft against the new profile. If the voice is not quite there, add another example post or sharpen the tone description.

Choosing example posts

The most common mistake is choosing polished, over-edited posts that do not reflect how you naturally write. The AI copies what you give it. If every example starts with a polished hook and a two-line opener, every generated post will too. Include at least one example that is messier or more conversational if that is how you sometimes post.

Voice improves with edits

Every time you edit a generated draft before publishing, Postbrander records the diff. If you routinely shorten sentences or cut a specific filler word, the model picks it up. Voice in month three is notably closer to yours than voice in week one.

Multiple profiles

Pro plans support two profiles. Business supports five. Useful if you post to both a personal profile and a company page, or if you manage content for more than one account.
