Voice fingerprinting

What is voice fingerprinting?

Voice fingerprinting analyses your top-performing posts and extracts the writing patterns that make your content distinctive — not just your topics, but your style. Postlore then applies that style to every AI suggestion it generates for your workspace.

It is different from your brand voice file (brand.md), which you write manually to describe your brand. The fingerprint is computed automatically from posts that have already proven themselves with your audience, including the posts Postlore imports from your accounts when you connect them, so it can be ready on your first day.

What it captures

• Sentence length — whether you write short, punchy sentences or longer, more explanatory ones
• Emoji density — how often you use emojis and where they appear
• Question frequency — how often your posts end with a question to the audience
• Exclamation ratio — the overall energy and enthusiasm level of your writing
• CTA patterns — the specific calls to action you use most ("Check the link", "Drop a comment", "Save this")
• Hashtag style — whether you group hashtags at the end or mix them inline

How to set it up

1. Go to Brand in your dashboard sidebar.
2. Scroll to Your writing voice.
3. Click Detect my writing style. Postlore will analyse your top-performing posts. It needs at least 10 posts with performance data, and posts imported when you connected an account count.
4. Review the detected patterns. You will see a summary like "Short sentences · Minimal emoji · Asks questions often · 'Check the link' CTA".
5. If the profile looks right, click Apply to my content. If it does not, publish more content and refresh the profile later.

Once active

When the fingerprint is active, every AI-generated suggestion — adaptations, humanised drafts, and content generated in your brand voice — is shaped to match your detected style. The badge "Active — shaping AI output" appears in Brand settings.

You can remove the fingerprint at any time by clicking Remove. The AI will fall back to your brand voice file only.

Refreshing the profile

As you publish more posts, click Refresh voice profile in Brand settings to re-analyse your latest top performers. The profile is a point-in-time snapshot and does not update automatically.

Which posts it learns from

The fingerprint needs at least 10 posts with real engagement data, never drafts. Two kinds count:

• Imported posts. When you connect YouTube, TikTok, Pinterest, Reddit or Bluesky, Postlore imports your recent posts with their numbers. On paid plans, Facebook, Instagram, Threads, Google Business Profile and LinkedIn posts are imported too.
• Posts published through Postlore, once their first week has been measured.

Your best posts are picked within each platform, so a platform that reports big numbers doesn't crowd out the others. If you see "Not enough post history yet", connect another account or publish more, then try again.
