Postiv
Postiv packages LinkedIn strategy, drafting, carousel design, scheduling, analytics and comment replies into a single weekly ritual run by an assistant called Bob, working through the official LinkedIn API rather than a browser extension.
- Diagnoses the failure as friction rather than motivation, and designs for that
- One weekly sitting is a workflow insight, not just another generator
- Built on the official API, so account risk sits with the platform's own rules
- Briefs convert composing into editing, which is far easier to begin
- Optimising briefs for engagement can converge on a generic LinkedIn register
- Streaks and leaderboards can feel coercive when they arrive from a manager
- Single-platform by design, so it does nothing outside LinkedIn
ViralBrain
ViralBrain analyses LinkedIn creators you nominate as heroes, extracts the hooks, structures and calls to action behind their posts, and generates drafts in your own voice on a scheduled calendar. It publishes through LinkedIn's official API, offers an MCP server, and ships a large library of free single-purpose tools.
- Extracts structure rather than text, which is the legitimate version of this idea
- Pattern application is explicit and clearable rather than always on
- Voice note input produces more specific material than typing
- Publishes through LinkedIn's official API, which keeps the risk off your account
- The headline creator figure describes posts analysed, not customers
- Example post cards carry identical engagement counts, so they are placeholder
- The four-times impressions claim has no stated methodology
