Claude Sonnet 4.5 is the best AI writer.
But only if you prompt it correctly.
Here's the exact prompt I use for all writing (articles, threads, emails):
---
"You are writing [CONTENT TYPE] for [AUDIENCE].
VOICE & TONE:
- [Describe voice: conversational, authoritative, casual, etc.]
- [Describe tone: humorous, serious, empathetic, etc.]
- [Key phrase: e.g., "Write like you're texting a smart friend"]
CONSTRAINTS:
- No AI clichés: delve, landscape, robust, leverage, utilize
- No generic openings: "In today's world..." "It's important to note..."
- No excessive transitions: "moreover," "furthermore," "additionally"
- Sentence variety: Mix short punchy sentences with longer explanatory ones
STRUCTURE:
- Hook that creates pattern interrupt (first sentence must stop scrolling)
- [Specific structure based on content type]
- Call-to-action or thought-provoking closer
CONTENT:
[Provide topic, key points, or outline]
OUTPUT:
[Specify length, format, or any special requirements]
Read your output twice before responding. If it sounds like AI wrote it, rewrite it."

The last line is KEY.
Claude will actually rewrite if it detects AI-speak.

Du kannst auch noch einen Schritt weitergehen und Leuten die ebenfalls kommentiert haben eine DM schreiben.
Hier ein kleiner Anreiz wie so eine DM aussehen kann:
