LinkedIn posts in your voice, written by Claude
LinkedIn rewards posts that sound like a person. Claude can learn your voice from past posts and turn rough notes into drafts; Postika schedules them on the LinkedIn account you connect.

Step by step
- 1
Give Claude 5 to 10 of your past LinkedIn posts so it learns your voice (a Claude Project works well for this).
- 2
Paste rough notes: a lesson, a client story, a number you are proud of.
- 3
Ask Claude for a draft under 3,000 characters and create it pending approval in Postika.
- 4
Read it in Postika, edit a line or two, add images if you want, and approve.
Example prompts
- Here are 8 of my past LinkedIn posts. Learn the voice. Then turn these notes about hiring our first salesperson into a post. Pending approval Tuesday at 08:00.
- Write three LinkedIn posts from this conference talk transcript, one idea each, for Tuesday, Wednesday and Thursday at 08:30. Leave them for my approval.
- Make this post less corporate: shorter sentences, no buzzwords, and a question at the end. Create it as a draft.
- Write a post about our new office for the Acme project, with space for 6 photos I'll add. Pending approval Friday 11:00.
- What do I have scheduled on LinkedIn in the next 3 weeks? Are any two posts on the same topic?
LinkedIn rules in Postika
- 3,000 characters per post.
- Up to 9 images per post in Postika (LinkedIn allows more; Postika's limit is 9), or one video.
- Text-only allowed, so Claude can schedule a LinkedIn post end to end.
Only the first lines show before "see more", so ask Claude for a strong opening line. Multi-image posts are covered in LinkedIn multi-image posts, and the general guide is LinkedIn scheduling.
Keeping your voice, not Claude's
The main risk with AI on LinkedIn is sounding like everyone else. Two things help. First, feed Claude your real writing: past posts, emails, a transcript of you talking. Ask it to describe your style back to you, then use that description in every request. Second, give it raw material only you have: specific numbers, names (with permission), what went wrong.
Postika's approval mode fits this well: Claude's draft lands in your calendar as pending, and you change the two sentences that don't sound like you before approving. If you write for more than one person, for example a founder and a co-founder, keep each LinkedIn account as its own channel, or in its own project, so Claude always knows whose voice it is writing in. Read Postika for startups and coaches. A quicker, idea-list approach is in ChatGPT for LinkedIn.
A weekly LinkedIn routine with Claude
- Monday: paste the week's raw notes (a client call, a lesson, a number) and ask for two or three drafts.
- Claude checks your LinkedIn calendar, places the drafts on your usual posting days and leaves them pending approval.
- Tuesday to Thursday: each morning, open the pending post in Postika, adjust it and approve.
- Friday: ask Claude which topics you covered this month, so next month does not repeat them.
Let Claude plan and schedule your social media posts
- 1
In Postika, connect the channels you want Claude to post to (Instagram, LinkedIn, X, Threads and so on) inside a project.
- 2
On claude.ai, open Settings → Connectors and click Add custom connector.
- 3
Name it
Postikaand paste the server URLhttps://postika.app/api/mcp. - 4
Click Connect, sign in to Postika and click Allow on the permission screen.
- 5
Start a chat and ask Claude something like "What is scheduled in Postika next week?" to check the connection. The same connector shows up in Claude Desktop and the Claude mobile apps on that account.
Frequently asked questions
Can Claude post to LinkedIn for me?
Yes, through Postika. Claude creates the LinkedIn post in Postika; by default it waits for your approval, or it can schedule it directly if you ask.
Can Claude write LinkedIn posts for several people?
Yes. Connect each LinkedIn account as a separate channel, or put each person in their own Postika project, and tell Claude whose post it is writing. Feed it that person's past posts so the voice matches.

Up to 3,000 characters in Postika, with up to 9 images.
