Features
Everything you need to own
your social presence.
PostSider gives your team a beautiful scheduling calendar and gives your AI agents a native API. One tool, every workflow.
What's inside
Built for teams and agents alike.
Every feature you'd expect from a pro scheduling tool, plus the developer primitives your automations need.
-
Drag-and-drop Calendar
Visualise your entire content plan on a weekly or monthly grid. Drag posts between days and channels with a single gesture. No forms to refill.
-
Composer & Media Library
Write rich posts with inline formatting, attach images and videos, and pull from a shared media library your whole team can access.
-
Automated Queues
Set recurring time-slot queues that drain automatically at your peak engagement hours. Fill the queue once and PostSider handles the rest.
-
CSV Bulk Import
Plan a whole month in a spreadsheet, then import it in one go. Map columns to channels and times, review the drafts, and fill your calendar in minutes.
-
Analytics & Reporting
Cross-platform reach, impressions, and engagement in a single dashboard. No tab-switching. Export custom reports to PDF or CSV in one click.
-
Approval Workflows
Send any draft for review before it goes live. Reviewers can approve, reject with comments, or request changes, all within PostSider.
-
Auto-plugs & First Comments
Schedule a thread reply or first comment to auto-post immediately after your main content publishes. Perfect for pinned links and CTA threads.
-
AI Post Checker
Run every draft through an AI check for platform limits, formatting and tone before it ships, and rewrite captions per network in one click. Use our AI or bring your own key.
-
Agent Access (MCP)
Let Claude, GPT, or any custom AI agent schedule and publish on your behalf via the Model Context Protocol. No bespoke glue code required.
-
REST API & SDKs
A predictable REST API with OpenAPI docs, plus an official TypeScript/Node.js SDK, so you can integrate PostSider from any stack in minutes.
-
Role-based Access
Grant every teammate the right level of access. Owner, Editor, and Viewer roles keep sensitive settings locked while giving writers room to create.
-
Security by Default
Channel tokens are encrypted at rest with AES-256-GCM, requests are hardened against SSRF and CSRF, and every channel is isolated with least-privilege access.
How it works
Up and running in three steps.
-
Connect your social channels
Authenticate with X, Instagram, LinkedIn, TikTok, and 36 more platforms in one OAuth flow. PostSider stores your tokens securely and refreshes them automatically.
-
Create or let your agent fill the calendar
Write posts in the composer yourself, or plug Claude, GPT, or your own LLM via MCP to generate and schedule content automatically. Either way, the calendar stays the source of truth.
-
Publish automatically with smart queues
Posts leave the queue at your optimal send times, perfectly formatted per platform. Sit back and watch the analytics roll in, or let your agent handle that too.
