ContentIn vs KnownVoice
Why switch to KnownVoice?
Not because ContentIn is bad. Because some LinkedIn workflows need a narrower focus on source material, point of view, personal takes, research, and human approval.
Start with real inputs
KnownVoice is built around feeds, URLs, notes, voice notes, YouTube videos, drafts, and source material before a post is written.
Set your perspective before research
The overall angle you believe is paired with the source material and researched together — so the research direction is informed by what you actually think.
Research source and perspective together
KnownVoice researches the topic against your perspective so drafts start with context instead of unsupported filler.
Add personal takes to the draft
Once the draft exists, add specific commentary from your experience so the final post sounds more like you.
Approval stays in the loop
Posts are reviewed before scheduling or publishing. The final judgment stays with the person whose name is on the post.
