Go past the job title: the problems you solve, the mistakes you've seen, the advice you disagree with. Every specific becomes an idea.
How to use it
- Describe what you actually know — not just the job title. The problems you solve, the mistakes you've watched people make, the advice you'd argue with. Optionally add who you write for.
- Hit Generate 15 ideas. The ideas come spread across five angle categories, each anchored to something specific you wrote.
- Pick the one that makes you slightly nervous to post — that's usually the winner — and take it to the post generator, or write it yourself.
Why idea generators usually fail — and what mining your expertise means
Type "marketing" into most idea generators and you get the listicle every marketer gets: "share a productivity tip", "post about industry trends", "celebrate a client win". These fail for a structural reason: they generate from the topic label, so they can only produce ideas that belong to everyone in the topic. Posts anyone could write are posts nobody stops for.
The fix is to change the input. This tool doesn't ask for your topic — it asks what you know deeply, and mines that. If you write "fractional CFO", you get generic finance content. If you write "I keep watching agency founders confuse revenue with cash," you get fifteen ideas only you can execute, because each one is anchored to an observation that came from your work. The quality of what comes out is set by the honesty of what goes in.
The five angle categories
- Lessons & mistakes. What went wrong, what it cost, what you'd do differently. The most reliable category on LinkedIn — earned failure beats borrowed success.
- Contrarian takes. Common advice in your field you disagree with, and the experience that made you disagree. (Our contrarian angles tool goes deeper on this one category.)
- Process. How you actually do the work — the checklist, the sequence, the decision rule. Practitioners sharing real process outrank gurus sharing theory.
- Stories. A specific moment with a turn in it: the client call that changed your pricing, the deploy that went sideways. Moments, not morals.
- Data. A number from your own work that surprised you. Even a small dataset — "we analyzed our last 40 proposals" — beats a big opinion.
Where ideas actually live
Here's the uncomfortable truth about content ideas: you don't have an idea shortage, you have a capture problem. Your best posts already happened this week — in the sales call where you explained the same concept for the third time, the voice note you rambled into on a walk, the commit message that summarized a hard-won fix, the Slack thread where you talked a colleague off a bad decision. Those moments are specific, true and yours; they just evaporated because nothing caught them.
This generator is the manual version of that mining: you describe your expertise from memory, it finds the angles. Liftli is the automated version — it runs inside the AI you already use and turns your actual voice notes, call transcripts, GitHub activity and chats into post seeds, then drafts them in your extracted voice. Developers: the devlog-to-post tool does the commit-mining version of this on one page.
