Postprism is an editor-first social media scheduler for B2B teams and solo founders. Like Hootsuite, Buffer, and Sendible, it schedules and publishes across every major network from one calendar, but it keeps you in control of every post and adds an AI assistant with MCP support to plan and adapt content conversationally, instead of forcing AI-generated output.

Postprism is editor-first: you stay in control of every post, and AI is an optional enhancement rather than a replacement for your voice. It pairs a multi-platform scheduler for 9 networks with a built-in AI assistant and MCP support, so you can plan and schedule conversationally and connect your own AI tools, which almost no other social media tool offers.
Most schedulers either make you log into a separate app per network or push generic AI-generated content. Postprism gives you one calendar for every platform while keeping you in the editor, with optional AI that adapts each post per network and preserves your brand voice. It is built mainly for B2B teams, with a plan for solo founders, and its AI assistant plus MCP integration make planning and scheduling faster than tools that bolt AI on as an afterthought.
Primarily B2B marketing teams, agencies, and SaaS or tech startups that publish regularly across multiple platforms, plus solo founders, freelancers, and creators who want team-grade scheduling and AI assistance without enterprise complexity. Typical roles include social media managers, content marketers, marketing managers, and founders.
Postprism started as a tool the founder built to promote their own product. Posting across every network meant either logging into a different app for each one or leaning on tools that replaced their voice with generic AI. So they built a scheduler for themselves: write once, customize per platform, and let optional AI and automation handle the busywork while staying in control of every post. What began as an internal tool for marketing one product grew into a full-fledged, editor-first social media scheduler, with AI and MCP as enhancements rather than the main event.
Postprism is built with Next.js and React, with Supabase on the backend and a Redis-backed queue for scheduled publishing. The UI uses TailwindCSS. AI features run on leading models via the Vercel AI SDK, and Postprism exposes an MCP integration so you can connect your own AI tools.
