Postfox is a LinkedIn content tool built for B2B founders and consultants who know what they want to say โ€” but struggle to say it consistently.

It starts by learning your writing style from your existing LinkedIn posts. Every post it generates sounds like you wrote it โ€” not generic AI output.

From there, a full content pipeline handles everything: generate daily post ideas tailored to your niche, write and refine posts with AI tools, organize drafts in a Kanban board, and schedule or publish directly to LinkedIn in one click.

Key features: AI voice matching, daily idea engine, smart post editor with rewrite tools, drag-and-drop content pipeline, LinkedIn scheduling and publishing.

Built exclusively for LinkedIn. No multi-platform bloat. Just a focused tool that helps B2B founders post consistently and grow their personal brand.

Starts at $29/month. Includes a 5-day free Pro trial โ€” no commitment required.
