MakePost App Growth (via makepost.com)

Manage your social media across 9 platforms — draft captions, hashtags & post ideas, generate AI images, schedule, publish, set recurring autopilot schedules, and trigger webhooks — all through conversation.

Social Media Toolkit (via makepost.com)

MakePost is a social media scheduling platform built to be driven by AI agents. Draft captions, hashtags, and post ideas, generate AI images, schedule, and publish videos, image carousels, and posts to 9 platforms — TikTok, Instagram, YouTube, Facebook, X, LinkedIn, Threads, Pinterest, and Bluesky — from one place or straight from your AI agent. Set recurring autopilot schedules that auto-publish a queue, and fire signed webhooks into n8n, Zapier, Make, or your own service.

Example Workflows

• "Post 'Just launched v2.0!' to all my accounts" — Creates a text post and publishes to all text-compatible platforms.
• "Upload this image and post it to Instagram and Facebook with the caption 'New feature'" — Uploads the image, then publishes to selected accounts.
• "Save a draft post about our upcoming feature for later" — Creates a draft that can be edited and published when ready. Accounts and per-platform captions are preserved.
• "Draft a post for X and LinkedIn with different captions for each" — Creates a draft with per-platform captions stored for later publishing.
• "Post to all accounts in my MakePost group" — Uses list_account_groups to find the group, then publishes with group_ids.
• "Upload https://example.com/my-video.mp4 and schedule it to all my accounts tomorrow at noon" — Downloads the video, runs moderation, and schedules across all connected platforms.
• "Post my latest video to TikTok and Instagram tomorrow at 3pm" — Finds your most recent video, picks the right accounts, and schedules it.
• "How did my last post do?" — Uses get_publishing_results to report status and engagement stats (views, likes, comments, shares).
• "Show me my drafts and publish the one about the launch to LinkedIn" — Lists drafts, then publishes the right one to the selected account.
• "List my projects and schedule this video under the Acme client" — Lists projects, then publishes with the project ID passed as app_id.

Bulk Operations

• "Schedule a week of posts — Monday text, Tuesday image, Wednesday video, Thursday text, Friday carousel, Saturday image, Sunday video" — Uses bulk_publish_content with 7 items, each with a different scheduled_at and content_type, all in one call.
• "Upload these 10 product screenshots and then post them all to Instagram and LinkedIn" — First calls bulk_upload_media with 10 image URLs, then uses the returned media_ids in bulk_publish_content to publish all 10.
• "Cancel all my scheduled posts for next week" — Lists posts filtered by status "scheduled", identifies the ones in the target date range, then calls bulk_cancel_posts with their IDs.
• "Move all my Friday posts to Saturday at the same times" — Lists scheduled posts, filters for Friday, then calls bulk_reschedule_posts with each post shifted by one day.

AI Generation

• "Write me a punchy TikTok caption for our new feature launch" — Uses generate_caption with the brief and platform "tiktok", then you can publish it directly.
• "Give me 10 hashtags for a fitness reel" — Uses generate_hashtags with the topic and count.
• "Brainstorm 5 post ideas about productivity, each with a hook and caption" — Uses generate_post_ideas and returns distinct angles ready to schedule.
• "Make an image of a sunset over mountains and post it to Instagram" — Uses generate_image to create the image (returns a media_id), then publish_content with that media_id.
• "How much of my AI quota have I used this month?" — Uses get_usage to report generation counts against your plan limits.

Platform Rules

• "What's the caption limit on X vs LinkedIn?" — Uses get_platform_rules to report per-platform caption limits.

• "Show me my webhook endpoints" — Uses list_webhooks_tool to list registered endpoints and the available events.

Recurring Scheduling (Autopilot)

• "Set up a plan that posts to TikTok every Mon/Wed/Fri at 9am, then queue these 6 videos" — Uses create_posting_plan_tool with three slots, then add_to_posting_queue for each video. Each slot auto-publishes the next queued item.
• "Pause my autopilot plan while I'm on vacation" — Uses pause_posting_plan, then resume_posting_plan when you're back.
• "What's left in my posting queue?" — Uses list_posting_queue to show upcoming items in publish order.

Tips

• Project auto-selection: If you have only one project, you can omit app_id from any tool — it auto-selects.
• Flexible project lookup: Pass a project name (case-insensitive) instead of the internal ID.
• Timezone handling: schedule_post and reschedule default to your account timezone if you don't specify one.
• Caption fallbacks: If no caption is provided, publishing uses the video's script, then its title.
• Per-platform captions: Use the captions dict in publish_content to write a different caption per platform.
• Drafts: Save content with is_draft=True, then publish or schedule it later with publish_draft_tool.
• Post to multiple platforms simultaneously by including multiple account IDs in schedule_post.
