CASSI made my LinkedIn presence consistent without extra effort.
Jeremy Froeboese · CTO at Audio Creatures
As an entrepreneur with two employees, I don't have time for social media. With CASSI, we're finally consistently present on Instagram and LinkedIn. From one idea, two audience-optimized posts are created super easily.
Holger · CEO at The Taste of Berlin
What I particularly appreciate about CASSI is the charmingly simple workflow: generate text and image, then post automatically right away. This makes the entire process incredibly straightforward and efficient.
Olaf Sacher · CEO at Printkit
Cassi ist die perfekte Verbindung von innovativen KI-Inhalten und der Umsetzung von eigenen Ideen. Manchmal ist es beinahe schade, dass die Erstellung von Social Media- Inhalten mit Cassi so easy ist, denn die Arbeit mit dem Programm macht einfach Spaß!

AI that makes you Post more and Stress less.
Three sets of twins before breakfast. The ewes did all the work — we just kept the kettle on and the straw dry. #lambing #familyfarm #springonthefarm
Connect CASSI to the AI tools you already use
CASSI speaks MCP, the open standard that lets AI assistants use real tools. Connect it to Claude, ChatGPT, Claude Code, Cursor, VS Code, GitHub Copilot, Gemini CLI, Windsurf, Zed, JetBrains, Raycast, Warp or n8n. Then ask for a week of posts, and CASSI writes them, designs them and schedules them.
Post from your chat window. Ask for a post in plain language. CASSI writes it in your voice, builds the visual, and queues it up.
Schedule without leaving the conversation. Pick the platform and the time. CASSI handles publishing to Instagram, LinkedIn, TikTok, Facebook and YouTube.
Ask what's working. Pull your own numbers into the chat, ask why a post did well, then make more like it.
Works with any MCP client. Included on every plan.
