Perplexity LinkedIn rewriter workflow

The job

What the Perplexity LinkedIn rewriter is for

You have a post drafted with Perplexity. It is accurate, it is competent, and it reads like the eleven other posts in the feed. This rewrites the prose: stock openers out, rhythm varied, the summarising ending cut, under a server instruction to preserve your meaning and factual claims.

It is a rewriter, so it needs your draft. Most free LinkedIn tools are generators that build a post from a topic. This one starts from what you wrote, which matters, because the part of a post worth keeping is the part only you could have supplied.

Write to these

The numbers the LinkedIn rewriter has to respect

Keep these in front of you while you edit. On this route the tool's 12,000-character ceiling is never the constraint, because every one of these is smaller.

3,000 characters

The hard limit on a LinkedIn post. If your draft is longer, the decision is what to cut, and that is your call rather than the rewriter's.

About 210 on desktop

What shows in the feed before the see-more link. Roughly five lines.

About 140 on mobile

The number that actually matters, since most of the feed is read on a phone. Two or three lines to earn the click.

1,250 characters

The comment limit, with no truncation. A comment is fully visible, so the opening-line pressure is lower there.

2,600 characters

The About section, which truncates at roughly 300. Same opener discipline, longer runway after it.

The run

How to run the Perplexity LinkedIn rewriter in three steps

One run, three steps, and a check afterwards that takes ten seconds and catches most problems.

Step 1

Paste the draft. Include your rough notes if you have them, since 12,000 characters leaves room and the specifics in your notes are what the post needs.

Step 2

Write the instruction, up to 300 characters. Two clauses: protect the specifics, and state the job of the opening line.

Step 3

Run it, then count 140 characters into the result. If the reason to keep reading is not inside them, edit the opener by hand.

The instruction box

Instructions that work on a post

There are no tone presets and no post-format menu here. Everything goes in the 300-character field, which is an advantage for this platform because the useful instructions are specific.

Protect the specifics

"Keep every number, name and date exactly as written. Do not generalise any of them."

Aim the opener

"The first sentence must contain the outcome and stay under 140 characters. No scene-setting."

Kill the template

"No bulleted list of three. No closing question. Do not summarise the point at the end."

Vary the lines

"Do not put a blank line after every sentence. Join at least one group of sentences into a paragraph."

Set the register

"Write it the way I would say it to a colleague. No corporate verbs: no leverage, unlock, delve or foster."

The real tell

The template readers recognise before the words

Cutting the stock phrases is the easy half and it is where most advice stops. The shape underneath survives every word swap, and on LinkedIn the audience sees it instantly because they scroll past it forty times a day.

The shape: a hook, often a manufactured vulnerability such as I almost did not share this, then three bullets, then a wrap that starts with something like here is why this matters, then a question asking for comments. Break it anywhere. Two points instead of three. No wrap at all. Stop at the sentence where the point lands. A post that ends abruptly reads as written by someone who had one specific thing to say, which is the impression you are after.

Worth knowing

The short-line disagreement

You will find both pieces of advice, and they conflict. One says LinkedIn's native voice is short lines, hooks and a scannable rhythm. The other lists repetitive short-line formatting as a mechanical rhythm and puts it with the AI tells.

Resolve it by degree rather than by picking a side. Short lines are genuinely easier on a phone. Eighteen consecutive one-sentence lines with a blank line between each is a format, and formats are what readers pattern-match on. Build one joined paragraph into the middle of every post and the problem goes away.

Your half

The edits you make after the run

This is where a post stops being interchangeable. None of it can be done by a rewriter, because all of it requires having been there.

Add one real number

A figure that was not in the draft. Not a rounded industry statistic, something from your own week.

Name someone or something

A client, a tool, a city, a job title. Specificity is information and generality is not.

Keep the awkward detail

The small fact that feels too minor to include is usually the thing that makes the post believable.

Write one disagreeable sentence

A judgement someone could argue with. A post nobody could disagree with is a post nobody needed.

Apply the anyone test

Could a competitor post this word for word? If yes, the sentences are not the problem.

Direct answer

Does this make a post undetectable?

No, and we make no claim about any detector. We do not test against them, are affiliated with none of them, and will not predict what any of them reports about a post.

On this platform the more useful point is that the audience does the detecting. A reader recognises the template in under a second and moves on without needing a tool to confirm it. Solve for that and the other question becomes much less interesting.
