Why creators choose ViralPosts over Buffer

AI is built in, not bolted on.Buffer's AI assistant is a limited add-on. ViralPosts's AI caption generator (5 tones, Groq) and AI image generation are built in for every user. You write less and publish more without leaving the app.

Live preview as you type.ViralPosts's split-view composer shows a pixel-accurate platform preview alongside your editor. You see exactly what your audience will see before you hit schedule. Buffer's preview is basic.

Built so posts don't slip.Temporary LinkedIn errors are retried automatically with backoff. If a post still fails, it's flagged on your dashboard with the error and a one-click retry.

Safe & private by default.We connect safely through LinkedIn's official login. We never see your password, never read private messages, and credentials never touch plain-text logs.
