PostAgent

PostAgent learns a professional's voice from their books, talks and posts, then drafts, fact-checks and publishes LinkedIn posts on a schedule. A multi-reviewer desk holds back claims it cannot verify, and the user previews posts before they go out.

PostAgent is a LinkedIn posting agent aimed at experts whose reputation carries their business: consultants, lawyers, finance and tax professionals, engineers and doctors. Instead of asking for a prompt, it studies material the user has already produced, such as books, guides, talk transcripts, technical notes and past posts, and uses that corpus to write posts meant to match the author's rhythm and vocabulary. The output is built to avoid common AI tells, including em-dashes and stock phrases. Setup starts with screenshots of a LinkedIn profile and a handful of existing posts, which can be captured from a phone. From those the agent drafts three posts within minutes, and the user rates them with a thumb up or down as the whole calibration step. Longer sources can be added later. Each week the coming posts arrive by email for review: a thumb up moves a post forward, a thumb down removes it and teaches the agent, and no response lets the schedule run as planned. Publishing goes through LinkedIn's own sign-in on days and times the user chooses, and any link is placed in the first comment automatically. A short weekly question by email supplies fresh material from real client work. What separates it from a single-prompt writer is the review pipeline. A writer drafts from a brief built on the user's material, then several reviewers, including one from a different AI vendor, check each claim against that material and the public record. A verifier rules on disputed passages, an editor makes minimal corrections, and any post that still cannot be vouched for is held back. The vendor states that this catches errors rather than guaranteeing none. Among alternatives, the site compares it with doing the work personally, hiring a ghostwriting agency, generic AI writing tools, self-trained chatbots and social posters bundled into larger platforms. PostAgent targets individual professionals who want a voice-faithful, checked LinkedIn presence at a flat monthly price, and it also has a page for agencies.
