PlanSend is a web-based social media scheduler for freelancers and small agencies. Plan posts in a calendar per brand, send private review links that clients can open without an account, and schedule the approved revision. Editing approved content returns it to review. AI Assist helps draft and adapt captions. A REST API and MCP server let scripts and AI assistants work through the same approval rules. A free plan is available, with paid subscriptions from $15 per month or $12 per month billed yearly. Integration availability varies as platforms approve access.
