Add Your API Key

Run the Daily Wizard

Each day, open the 15-minute guided workflow. Comment on 5 to 6 profiles, draft your post, publish it, and track replies, all in one place.

3

Track Your Growth

See follower growth, post impressions, engagement scores, and leaderboards for both LinkedIn and X over time.
