Phantomwriter
Phantomwriter generates LinkedIn posts by analysing your industry, competitors and ideal customer profile, then producing tailored post ideas and drafts with a content calendar. It states 10k+ posts created and is run by two named founders.
- Research before generation is the correct order and the real differentiator
- Idea generation addresses the actual bottleneck, which is angles rather than writing
- A content calendar targets consistency, which is the mechanism on LinkedIn
- Focused on one network rather than spreading across five badly
- 100% AI undetectable is not something any vendor can guarantee
- Detectability is the wrong target — readers notice sameness, not detectors
- Research produces topics, not the opinion that makes a post worth reading
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
