Content ideas generator

By Jack Stovell X · Instagram · LinkedIn · published 2026-10-02 · updated 2026-10-02

This tool reads the writing you've already done and suggests what to write next, based on what you've actually said. It's free, and it's built for anyone who keeps asking "what should I post today?"

Paste or link two to five of your own pieces (a LinkedIn post is long enough, as long as each runs at least 60 words) and you get five ideas for what to write next, up to three threads you keep coming back to, and up to two pairs of claims that pull against each other. Every suggestion shows the words of yours it came from. No signup, no account, nothing stored.

Why most idea generators give you someone else's ideas

You've probably tried a few. You type in "LinkedIn post ideas" or "blog post ideas generator", and out comes a list. Ten angles, tidy, confident. And here's the thing: it's the same ten for everybody. The founder, the consultant, the ghostwriter, the person who just wants to get through Monday's newsletter.

That's because a generic list doesn't know you. It doesn't know what you've argued, what you keep repeating, or what you've left hanging. It's guessing, and the guess is built for the average person, who doesn't exist.

What you get

Three things.

First, five angles to write next. Each one builds on one or two things you've said, and names what your pieces haven't said yet. Maybe it's a consequence you never drew. Maybe it's an objection you never answered, or a story that would prove a claim you only asserted.

Second, up to three threads you keep coming back to across different pieces. You might not have noticed them. Most people don't.

Third, up to two pairs of claims from different pieces that pull against each other. That tension is often where the next piece is.

Each item shows your own quoted words. It never invents facts, numbers, clients or events about you, though an angle may ask you to supply one.

How it reads your writing

Each piece goes through the same extractor ScriptGrain's Voice Brain uses. It pulls out ideas, claims, stories and frameworks, and it keeps each one only if it can point to the exact words in your piece that it came from. No quote, no memory.

Anything it can't trace back to your words gets thrown away. That's the whole rule, and it's why the suggestions feel like yours rather than like a horoscope.

Nothing you paste is stored. The run is logged without the text. You get up to five runs an hour.

When one run is not enough

One run is a snapshot. Useful, but a snapshot.

If you write in ScriptGrain, Voice Brain does the longer job. It remembers the ideas, claims, stories and frameworks across everything you write there, each with its quote. It links pieces as repeats, builds on, contradicts or refines. Before you write, it checks whether a brief repeats you, builds on you or is new, and it suggests what to write next. It's on every plan, including Free, and it works in the app, the API and MCP.

The voice profile is the other half. It measures how you write across 45 attributes. The brain remembers what you said, the profile learns how you say it. ScriptGrain measures your writing; it never trains a model on it.

The Free plan gives you one profile, one full analysis and one free draft, no card. Paid plans start at $17 a month.

Paste a couple of your pieces into the tool above and see what comes back. It costs nothing, and it only knows what you've already said.

Questions

What should I write next, based on what I have already posted?

Paste two to five of your own pieces into the free content ideas generator on this page. It reads what each one argues, then suggests five pieces that build on one or two things you have said and names what your pieces have not said yet, such as a consequence you never drew or an objection you never answered. Each suggestion shows the words of yours it came from.

Is this a LinkedIn post ideas generator?

It works on LinkedIn posts, newsletters, blog posts and articles alike, as long as each piece has at least 60 words. The difference from a generic LinkedIn post ideas list is that the ideas come from what you have already written, so they are yours rather than the same ten everyone else gets.

Do you keep what I paste, or train AI on it?

No. Nothing you paste is stored, and the run is logged without the text. ScriptGrain measures writing; it never trains a model on it.

How is this different from asking ChatGPT for post ideas?

A chatbot asked for post ideas has not read what you have published, so it suggests what suits an average writer. This tool reads your own pieces, keeps only the ideas, claims, stories and frameworks it can tie to an exact quote from them, and builds every suggestion on those. It never invents facts, numbers or clients about you.

Can it remember everything I have written, not just a few pieces?

Yes, inside ScriptGrain. Voice Brain remembers the ideas, claims, stories and frameworks across everything you write there, each with its quote, links pieces as repeats, builds on, contradicts or refines, and checks every new brief before you write. It is on every plan, including Free.
