November 2026 comparison

Supergrow vs Postwise LinkedIn only, or three networks at once.

Supergrow is LinkedIn only: it writes posts from an AI interview and adds carousels, a first comment, stats and team approvals for $39 a month. Postwise writes AI drafts and schedules them to X, LinkedIn and Threads, with 500 AI posts a month on its $37 plan. Both connect through LinkedIn’s official sign-in. I paid for Postwise for a month and tried Supergrow on 7 November 2026.

5 differences that matter.

  1. 1

    How it writes

    Supergrow

    Mostly from PostCast, an AI interview on one topic (10 to 15 minutes on its site, 30 in the app), plus repurposing from YouTube, articles and PDFs. Content DNA learns from your posts.

    Postwise

    Several drafts per idea, 500 AI posts a month on the $37 Basic plan. 3 custom AI voices on Basic; custom AI training only on the $97 plan.

  2. 2

    Networks

    Supergrow

    LinkedIn only, personal profiles and company pages.

    Postwise

    X, LinkedIn and Threads, with 3 accounts on Basic. Built for X first; its help centre was last updated in 2023.

  3. 3

    Price and trial

    Supergrow

    $39 a month for one account ($31 yearly), $199 for Teams of 5. 7-day trial with a card asked for during sign-up. No refunds beyond billing errors.

    Postwise

    $37, $59 or $97 a month. A 7-day trial its pricing page says needs no card, while also saying you’re subscribed when it ends. The terms say purchases are final, despite a 30-day refund promise.

  4. 4

    Carousels and extras

    Supergrow

    A carousel maker with templates, an automatic first comment, Engage for comments, a Kanban board and a viral post search.

    Postwise

    Schedules carousels you made elsewhere. No first comment, preview or engagement tools described.

  5. 5

    If you cancel

    Supergrow

    Cancel under Payments. Deleting your workspace alone doesn’t cancel the trial.

    Postwise

    Cancelling deletes all your generated posts, drafts and settings.

First-hand

One made up stats. One made up a story.

Kaustubh KatdareFounder, Wiral.Social

I used Postwise for a month. The first two days were good, then the posts kept repeating one pattern, and some came with stats I never gave it.

Supergrow’s posts came from a six-minute AI interview. They were inspired by what I said, but parts of the story were made up, and every post was on the one topic I’d picked.

Whichever you choose, read every post before it goes out. Three networks and lots of drafts: Postwise. LinkedIn depth and teams: Supergrow. Posts in your own voice, from a single line, is why I built Wiral.
