    Prospel vs Supergrow

    Supergrow is a LinkedIn tool that learns your voice (Content DNA), turns AI interviews into posts (Postcast), repurposes videos and articles, makes carousels, schedules posts and offers team workflows. It connects through LinkedIn's official API.

    Prospel is an AI ghostwriter for X and LinkedIn: it learns how you write, drafts posts from things that really happened and publishes them on a schedule you approve.

    Checked on 23 October 2026

    The short version

    Choose Supergrow if

    • LinkedIn is your only platform
    • you'd like to create posts by being interviewed, or by repurposing YouTube videos, articles and PDFs
    • you run LinkedIn for a team and need approval workflows and an organisation dashboard

    Choose Prospel if

    • you post on X as well as LinkedIn
    • you want each draft scored and cleaned of common AI-writing tells before you see it
    • you want personal stories limited to ones you have given it, with invented anecdotes rejected in code

    What Supergrow offers that Prospel doesn't

    • Postcast: unlimited AI interviews that become posts.
    • Repurposing from YouTube, articles and PDFs, and a carousel maker.
    • Team features: approval workflows, shared calendars, publishing on behalf of members, leaderboards and Slack notifications.
    • A lower starting price ($39 a month, $31 billed annually) and a 7-day trial.

    How Prospel approaches writing

    Personal stories in posts
    Only from your own story bank (your answers) and your GitHub pull requests. Drafts with invented first-person anecdotes are rejected in code.
    AI-writing tells removed
    Code-enforced rules remove em dashes, hashtags, markdown asterisks, "It's not X, it's Y" and reflexive closing questions from every draft.
    Draft scoring
    Oracle Score (0 to 100) on every draft. On X it follows X's open-sourced ranking code; on LinkedIn, LinkedIn's public statements about its feed.
    Publishing control
    Nothing posts without your approval unless you switch on auto-approve. Replies to mentions are drafted when you ask, and you post them yourself.

    This describes what Prospel does. It isn't a claim about whether Supergrow does something similar.
