How to find LinkedIn post ideas in work you have already done
If you have nothing to post, you are looking in the wrong place. LinkedIn ideas are not invented at a blank screen; they are in the work you already did. The question a customer asked twice and the paragraph you wrote to justify a price are both posts. This guide is a method for finding them: where to look, what marks a passage as a post, how an AI assistant can go through documents faster than you can, and how to keep the supply from drying up. It is about finding ideas in working material, not about reshaping finished articles.
Start in your sent folder
The best source is the least glamorous: messages you have already written to explain something. Search your sent mail and chat history for the past month and look for replies longer than five lines. Each is a piece of expertise that somebody needed badly enough to ask for, and that you have already put into words for a real person. One explanation to one customer is, with the names taken out, very nearly a post — and it starts from a real question rather than from “what shall I write about?”.
Collect the questions people ask twice
A question asked once is a conversation. Asked twice, it is a gap in what your market understands, and a post that closes it will be recognised by everyone who has not asked yet. Keep a running note — a document, a pinned chat, anything — and add to it whenever a customer, a prospect or a new colleague asks something you have answered before. Sales calls and support requests are the richest places to listen. The list fills faster than you expect.
Read your documents for claims, not summaries
Proposals, reports, workshop slides and internal memos are full of posts, though not where you would look first. The summary on page one is the least useful part. Look for the sentence where you argued against the obvious option, the figure you had to explain, the recommendation a client resisted, the aside that begins “in practice, however”. A passage is a post when a stranger in your field could disagree with it or would want it explained. One document usually holds several, and none of them is its title.
Let an assistant do the first pass
Going through a forty-page report for five sentences is slow work for a person and quick work for an AI assistant. Give it the document and a narrow instruction: “List up to ten statements in this text that a practitioner might disagree with or want explained. Quote each one exactly. Do not summarise.” Exact quotations keep the list honest, because you can check each against the source, and “do not summarise” stops the assistant flattening the document into the generalities you are trying to escape. You choose from the list. It does not choose for you.
Take the client out before the document goes in
Work documents contain other people's information. Before you upload one anywhere, remove the names, the figures that identify a customer and anything covered by an agreement — or use a version that never had them. Check what the service does with what you give it: on their consumer plans, OpenAI and Anthropic each have a setting for whether your content may be used to improve their models, and both say their business plans are not used for training by default. And think about the post itself. A story the client would still recognise as theirs needs their permission, however well you disguised it.
Put the sources where your tool can use them
Ideas found once should not have to be found again. In MediaPilot, the documents you upload — presentations, PDFs — and the links you add, such as your website, product pages and case studies, are summarised and kept as context, and the topic pool is built from them together with your profile. Each topic says who it is for, what it claims and why it matters. A connected AI assistant can read the same pool, which means “what should I post this week?” is answered from your own material rather than from general advice.
Choose by what you can add this week
A backlog of forty ideas is not a plan. When it is time to write, do not pick the most impressive topic. Pick the one you can add something to today: the call you had yesterday, the figure that came in on Monday, the objection you heard twice. An ordinary idea with a fresh detail beats a strong idea written from memory. If your source is a finished article rather than working material, the job is reshaping rather than finding, and media-pilot.io/guides/repurpose-content-into-linkedin-posts covers it.
