About
Posthex is a social media scheduling and automation tool. Write a post once and publish it to X, Instagram, LinkedIn, Facebook, TikTok, YouTube, Threads, Bluesky, and Pinterest at the same time, or schedule it for a later date from a calendar view.
Posthex includes AI-generated captions and hashtags, a link-in-bio landing page, per-platform analytics, and a team approval workflow so agencies can require client sign-off before anything is published. Accounts connect through each platform's official OAuth login rather than shared passwords, and access tokens are stored encrypted.
A free plan is available (1 connected account, 5 scheduled posts per month). Paid plans unlock more connected accounts, more scheduled posts, the AI features, the bio page, and the team approval workflow.

About
SynthPrism is a web-based social media drafting and scheduling workspace for local trade and appointment businesses, including home-service contractors, salons, barbers, studios and med spas. AI uses saved brand details to draft captions and create images or short voiced clips, which users can organize on a calendar for scheduled publishing. Users connect Bluesky, Facebook Pages, Instagram Business and Pinterest on the free plan; X publishing is available on paid plans. Client approval links let owners review posts, approve them or request changes before publication. A results screen summarizes activity by channel, while a shared library and setup guide support content workflows. Part of the Martello software stack, SynthPrism can use business information saved in Mycel when connected. Plans vary by brand count, AI credits, storage, post limits and team seats; a free tier and monthly or annual paid plans are available.
