AI writer for LinkedIn
LinkedIn writing is high-stakes and time-consuming. A post can bring a job offer, a comment can start a customer relationship, a DM can land a client. Here's how to use AI to draft all three faster — without sounding like every other AI-written LinkedIn post you scroll past.
Three things to write on LinkedIn
- Original posts — your ideas, stories, milestones
- Comments — thoughtful replies on other people's posts
- Connection notes + DMs — outreach that gets replies
Different tone, different structure per each. Below.
Setup
- Install WriterPi.
- Pin the icon.
- Open LinkedIn.
- Click the WriterPi icon → sidebar opens.
Writing original posts
The best LinkedIn posts have a hook, one strong opinion, a story, and a takeaway. Ask WriterPi:
- "Write a LinkedIn post about [topic], first-person, one clear opinion, include a short story from real life"
- "Draft a LinkedIn post about my Q3 milestone — hit $10k MRR as a solo founder — keep it humble and specific"
- "Write a hot take on [industry topic]. One clear position, no fence-sitting"
Then edit: replace any generic story with a real one from your life. Cut any sentence starting with "In today's world" or "As we all know". Add your name for a specific person or company. That's the difference between a post that gets 3 likes and one that gets 300.
Writing comments
Comments are underrated. Most people scroll past. A thoughtful comment on the right post gets more visibility than most of your original posts. To draft one:
- Open the post you want to comment on.
- Open WriterPi + turn on the Page toggle (so it reads the post).
- Type: "Write a 2-sentence comment agreeing with the author but adding one specific example from my industry [say what industry]" or "Write a 2-sentence comment respectfully pushing back on the author's point".
Golden rule: comments should be 1-3 sentences. Longer than that and you're writing your own post in someone else's comment section — it reads as competitive, not additive.
Writing connection notes
LinkedIn's default "I'd like to add you to my professional network" is a red flag. A good connection note references something specific.
- Open the person's profile.
- Open WriterPi + turn on Page.
- Type: "Write a LinkedIn connection note under 200 chars. Reference something specific from their profile. Casual tone. My angle is [why you're reaching out]."
The 200 char limit is real — LinkedIn cuts you off. Under that, personal, one specific reference. Accept rate goes from 15% to 60%.
Writing DMs
For cold DMs specifically: mention how you found them, what you actually want, and make it easy to say no. AI helps with structure, you provide specifics.
Prompt: "Write a LinkedIn DM to a marketing director. I saw their post on [topic]. I want to offer to write a guest article for their company blog. Keep it under 4 sentences. Casual professional. Make it easy for them to say no."
Tone picker for LinkedIn
- Professional — safe default for anything customer-facing.
- Friendly — outreach, connection notes, comments.
- Casual — comments where you want to sound human.
- Concise — DMs, short posts, comments.
- Detailed — technical LinkedIn posts, thought leadership.
- Funny — sparingly, and only if humour is your brand.
What to never do with AI on LinkedIn
- Never post an AI draft without editing for YOUR voice. Everyone can smell it.
- Never let AI invent numbers, quotes, or credentials. It will. Fact-check.
- Never mass-generate 20 comments across strangers' posts. LinkedIn's algorithm demotes this, and readers spot it.
- Never automate posting. AI drafts, you post manually. Automation triggers LinkedIn's spam filters.
