Which is best: Taplio, Supergrow or AuthoredUp?
It depends on your job. Taplio suits someone who wants a growth suite in one place. Supergrow suits a marketing team getting several experts to post, with approvals and team analytics. AuthoredUp suits someone who already writes their own posts and wants formatting, previews and deep analytics.
- Taplio says its AI is trained on 3 million+ posts and turns what you describe into a post. It also lists auto-connecting and DMs to warm leads, and says it puts growth on autopilot. If you use outreach, read LinkedIn's rules on automation first.
- Supergrow starts from a 10 to 15 minute AI interview, builds a Content DNA profile, and turns videos, PDFs and voice notes into posts. Its team side adds approval routing and a leaderboard.
- AuthoredUp is a Chrome extension and web app. It adds formatting, hooks, a readability grade and a preview, then analytics and your saved posts. It says it does not collect your cookies and hosts data in Germany.
