The Problem

Managing social media is a full-time job

You juggle multiple platforms, adapt tone and format for each one, try to post consistently, and somehow maintain a coherent strategy. Existing tools either schedule posts (but you still write everything) or generate text (but with no strategy or scheduling).

Without PostKast

  • Hours spent writing and adapting posts manually
  • No coherent strategy across platforms
  • Expensive SaaS subscriptions that stack up
  • Your data lives on someone else's cloud

With PostKast

  • AI generates complete campaigns from a single topic
  • Coherent strategy with content pillars and weekly plans
  • One affordable tool — $9/month for unlimited everything
  • Desktop-native, privacy-first — your data stays local

Publish everywhere from one place

Features

Everything you need to grow your audience

Powerful tools designed for creators, marketers, and teams who want to save time and post consistently.

AI Content Generation

Generate captions, strategies, and weekly plans with OpenAI & Claude. Adapt a single idea to every platform in seconds.

Campaign Management

Organize everything into campaigns with content pillars, goals, and multi-platform strategies — all in one place.

Smart Scheduling

Set daily, weekly, or custom recurring schedules. A 30-second polling engine makes sure your posts go out on time, every time.

Multi-Platform

Publish to Twitter/X, LinkedIn, Instagram, and Facebook. One post, adapted to each platform's style and limits.

MCP Integration

Connect AI agents like Claude Code or Claude Desktop directly to your campaigns via the Model Context Protocol.

Desktop Native

Runs locally on Windows, macOS, and Linux. System tray, notifications, auto-updates — no browser tab required.

How It Works

From idea to published in three steps

01

Create a Campaign

Define your goals, target platforms, and content pillars. Let AI generate a complete strategy and weekly plan for you.

02

Generate & Customize

AI produces platform-adapted posts. Edit, refine, or bulk-replace text across your entire campaign in one click.

03

Schedule & Publish

Set your recurring schedule and let the engine handle the rest. Get notified when posts go out or need attention.

Why PostKast

Not just a scheduler. Not just an AI writer.

PostKast is the first tool that combines strategy, generation, and publishing in one place.

Traditional schedulers

Buffer, Hootsuite

Schedule posts, but you still write everything yourself. No strategy, no AI.

AI writing tools

Jasper, Copy.ai

Generate isolated text snippets. No campaign logic, no scheduling, no publishing.

PostKast

Generates complete campaigns with strategy, content pillars, platform-adapted posts — and publishes them on schedule.

Strategy + AI + Scheduling

Built-in Strategy

Not just posts — complete campaigns with content pillars, goals, and narrative progression.

AI Storytelling

Posts form a logical sequence — narration and progression, not random isolated content.

Human-First

You review and approve every post. More natural, less robotic, better engagement.

Zero Friction

Notification, copy, post. Or let the scheduler handle it automatically. Maximum speed.

Powered by AI

Let AI do the heavy lifting

PostKast integrates OpenAI and Anthropic Claude to generate complete campaign strategies, content pillars, weekly plans, and platform-adapted posts. You bring the idea — AI handles the rest.

  • Generate entire campaigns from a single topic
  • Adapt posts to each platform's tone and limits
  • Bulk edit text across all posts at once
  • Connect AI agents via MCP server
  • Use your own API keys — no hidden AI costs
// AI generates your content
const campaign = await ai.generate({
topic: "Product launch",
platforms: ["x", "linkedin"],
weeks: 4
})
// 28 posts ready to schedule
