How to comment without sounding like AI
~9 min readUpdated June 2026
TL;DR
- • AI comments fail because they sound like templates, not reactions to a specific post.
- • Good comments add something: a detail, a real question, or a specific disagreement.
- • Your sentence rhythm, vocabulary, and default tone are more recognizable than the content itself.
Why people can tell when you didn't write it
AI comments have a pattern. They feel like they were generated from a playbook, not written in response to a specific post. The words are correct. The tone is pleasant. But nothing proves you read past the headline.
People remember voices, not templates. A comment that sounds specific — tied to the post, the person, the moment — is infinitely more valuable than one that could fit anywhere.
Root causes of AI-sounding comments
Avoid generic opening phrases
Generic (AI-like)
Great post! Thanks for sharing this valuable insight.
Specific (human)
This works because it names the tradeoff: consistency creates reps, but quality decides whether those reps teach anything.
Be specific to the post

Love this perspective. Really important points here.

The part about distribution being harder than product — this is the thing most founders skip until month 8.
Add personal experience

This is so true. Everyone should know this.

I learned this the hard way shipping 3 products before I got distribution right. Agree completely.
The eight signals of authentic voice
Your writing fingerprint is made of these eight signals. Preserve them, and every comment sounds like you.
1.Sentence rhythm (short + punchy vs. flowing)
2.Contractions ("you're" vs. "you are")
3.Formality level (casual vs. professional mix)
4.How you open (direct, contextual, or question-based)
5.Phrases only you use ("The thing about..." or "This is what happens when...")
6.Vocabulary fingerprints (specific words you favor)
7.Words you avoid (phrases that aren't in your vocabulary)
8.How you break lines (one-liners vs. dense blocks vs. bullet points)
