You're building your own thought leadership. One person, one voice, published consistently.
You want engagement too — AI comments and a curated feed — or you run LinkedIn for other people.
Choose Supergrow if LinkedIn is a wider operation for you: commenting at volume with AI help, or managing several executives' or clients' profiles from one workspace with approval chains.
Choose ThoughtFuel if the job is your own reputation. You want what you know turned into posts that sound like you, at less than half the price, without paying for engagement automation you won't switch on.

The actual difference
Supergrow and ThoughtFuel are trying to solve the same problem for the same person, and both train on your voice. That part is a genuine tie — anyone telling you otherwise is selling something.
The split is what each one grows into. Supergrow extends past publishing in two directions: engaging — a curated feed with AI-written comments — and doing it for other people, with team accounts, client workspaces and approval chains.
ThoughtFuel goes in neither direction. It's one person publishing their own thinking. No AI commenting on your behalf, no seats, no approvals.
That's a real fork, not a feature gap. If LinkedIn is an operation you run — for yourself at volume, or for other people — Supergrow is built for that and we aren't. If it's your own reputation you're building, you'd be paying for machinery you never switch on.
What you get for $8 a month with ThoughtFuel
- Live Research — tell ThoughtFuel your domain and the AI researches current sources to suggest post ideas.
- Writing Style profiles trained on samples you paste in. Up to five per account.
- Three draft angles per topic, so you choose a direction rather than editing whatever came out first.
- An AI editor with inline rewrites and version history — changes stay local instead of regenerating the post.
- Native LinkedIn preview — exactly how it'll look before it goes out.
- Scheduling and publishing through LinkedIn's official OAuth and Posts API.
- AI image generation inside the editor.
- AI memory — it remembers what you've written and what you keep returning to.
When Supergrow is the better tool
- You want help engaging, not just posting. Their Engage feature gives you a curated feed and AI-generated comments. We don't do this and don't intend to. If commenting at volume is part of your strategy, they support it and we don't.
- You run LinkedIn for other people. Teams starts at four accounts with approval workflows and a multi-client workspace. ThoughtFuel has no seats, no clients, no approvals — and this isn't a roadmap gap, it's a different product.
- You want to be interviewed rather than write. Their PostCast feature asks you questions and builds posts from the answers. For people who talk more easily than they type, that's a genuinely better input model than a blank chat box.
- You post from YouTube videos. Supergrow repurposes them; we don't. We take pasted articles, links and attached documents, but not video.
- You want analytics. Profile analytics and a weekly report come with Pro. We have none yet.
Why people switch from Supergrow
$8 a month against $19, for the writing workflow without the engagement and team layers on top.
Live Research reads what's currently happening in your field and suggests angles, rather than only working from material you already have.
Client seats, approval chains and team dashboards are worth paying for if you run LinkedIn for other people. For your own profile they're overhead.

Frequently asked questions
Is ThoughtFuel cheaper than Supergrow?
Yes. ThoughtFuel is $8 a month or $80 a year. Supergrow's Starter plan is $19 a month, or $16 a month billed annually, with Pro at $39. At the entry points that's $96 a year versus $228 — less than half.
Does Supergrow train on your voice like ThoughtFuel does?
Yes. Supergrow builds a voice profile from your vocabulary, tone and topics, and describes it as writing like you rather than for you. This is a genuine tie between the two products — the differences are elsewhere: price, where post ideas come from, and whether the tool also handles engagement.
What's the main difference between ThoughtFuel and Supergrow?
Not voice training — both do that. Supergrow extends past publishing into engagement, with AI-written comments and a curated feed, and into running LinkedIn for other people, with team accounts and approval workflows. ThoughtFuel does neither. It's built for one person publishing their own thinking, and priced accordingly.
Can I bring my own articles or documents into ThoughtFuel?
Yes. Paste an article or a link and it reads the page, or attach a PDF, DOCX, PPTX, TXT or MD file and draft from that. It works the same on every plan. Supergrow additionally repurposes YouTube videos, which we don't.
Does ThoughtFuel have an engagement or commenting feature?
No. Supergrow offers a curated feed with AI-generated comments. ThoughtFuel is built for publishing your own thinking rather than for engaging at volume, so nothing automated touches your account beyond publishing your own scheduled posts.
Can ThoughtFuel manage multiple client accounts?
No. There are no team seats, client switching or approval workflows. If you run LinkedIn for clients, Supergrow's Teams plan is built for it and ThoughtFuel isn't.
