Supergrow is a LinkedIn content platform for individuals and teams, with AI interviews, scheduling, analytics, approvals and an Engage workspace for comments. Voxily only drafts replies and comments, inside the reply box on LinkedIn, X and Reddit, and you post them yourself.

Here's how Voxily handles this workflow, and what you can check yourself in the extension.
Pick by where you want to write the comment and what you need around it.
Supergrow's pages list post scheduling, AI interviews that turn a short conversation into post drafts, repurposing of videos, articles and PDFs, carousel and infographic makers, profile analytics and team approvals. It also builds engagement lists by profile URL, CSV or a post's commenters. Voxily has none of these.
Voxily drafts in the reply box on the site you are already reading, on LinkedIn, X and Reddit, from one persona and one set of saved knowledge. Its Free plan is ongoing, not a trial, and Pro is $12.99 a month. Supergrow lists Engage from its Pro plan, $39 a month.
Voxily drafts. You review, edit, and post the final text.
Choose a LinkedIn post where you can add a specific point, question or example from your own work.
Add it to desktop Chrome, sign in and save one persona with two or three of your own posts as writing examples. No card is required.
Generate a draft, remove anything you would not say and add one detail only you know.
If you also need interviews, scheduling or team approvals, Supergrow's trial is the fair comparison. Voxily offers no Supergrow import or migration.
Quick answers before you install.
No. Voxily covers comment and reply drafting only. Supergrow also lists scheduling, AI interviews, repurposing, analytics and team approvals. If you rely on those, Voxily does not replace them.
Its Engage page says there is no browser extension to install: each person connects LinkedIn through OAuth and comments from inside Supergrow. We did not find a current Chrome Web Store listing for Supergrow on October 3, 2026.
Supergrow's Engage page says Engage is available from the Pro plan onward, listed at $39 a month billed monthly. Starter, at $19, does not list Engage. Plans change, so check their pricing page before you buy.
No. Voxily puts a draft in the reply box on LinkedIn, X or Reddit. You edit it and click post yourself. Free gives you 10 replies a day with no card.
Start with one real reply on X/Twitter, LinkedIn, or Reddit. Keep the draft only if it sounds like something you would actually post.
