Edgar vs Postiv: honest comparison

Postiv markets itself as the AI replacement for a $3,000-a-month ghostwriter. It runs an AI agent that studies your connected profile, your best past posts, and documents you upload, then drafts posts and carousels, schedules them, and tracks results. Edgar shares the ghostwriter goal but takes a different input: you talk for 10-15 minutes and it writes from that. The split is text-trained versus voice-first.

Edgar writes your LinkedIn posts from a 10-minute weekly call. Talk once, post all week, in your own voice.

The verdict

Pick Postiv if you want an end-to-end studio with carousels, analytics, lead tracking, and team or agency seats, and you already post enough for it to learn your style. Pick Edgar if you want the simplest path from idea to finished post: talk for 10-15 minutes and publish. Postiv positions itself as the AI replacement for a $3k ghostwriter, though it still works from your existing writing. Edgar works from your voice, which helps most when writing is the bottleneck.
