One video on TikTok, Reels and Shorts, set up by AI

Tell Claude or ChatGPT which video to post. It writes a TikTok caption, a Reel caption with your cover, a searchable YouTube title, picks the playlist and schedules all three in RobinReach.

Post the morning mobility video from my library to TikTok, Instagram Reels and YouTube on Thursday at 6 PM. Use my cover image and put it in the Morning mobility playlist.

What it did in RobinReach
  1. Found the video and your cover image in the library
  2. Checked your YouTube playlists
  3. Wrote a version for each network and checked them
  4. Scheduled it on all three for Thursday at 6 PM

Scheduled for Thursday at 6 PM on all three. TikTok gets a short caption, the Reel uses your cover image, and YouTube gets a searchable title in your Morning mobility playlist. YouTube files short vertical videos like this one under Shorts on its own.

What your AI uses to do it

Your assistant brings the thinking and the writing. RobinReach gives it hands: these are the parts of RobinReach it works with to get this done.

  1. Your AI assistant

    Claude, ChatGPT, Gemini, Codex or Cursor. You brief it the way you would brief a person, and it decides which RobinReach actions to take, in what order.

    Connect yours in two minutes

  2. Video, Reels and Shorts

    Sets each network's options: the Reel and its cover on Instagram, privacy on TikTok, title, privacy and playlist on YouTube.

  3. Publishing to 13 networks

    Writes a caption per network, checks each one, then schedules the video everywhere at once.

  4. One video, three networks

Step by step

How it works

What happens between your message and the result. The small labels are the RobinReach actions your AI calls, in case you are curious.

  1. Connect your AI to RobinReach, once

    In RobinReach, open Integrations and copy your connector link. Add it to Claude, ChatGPT or another assistant as a connector. It takes about two minutes and you never repeat it. Watch the setup for Claude or ChatGPT.

  2. Found the video and your cover image in the library

    Your AI finds the video and the cover by name in your RobinReach media library.

    media_search

  3. Checked your YouTube playlists

    It looks up the real playlist instead of guessing, so the video lands in the right one.

    youtube_list_playlists

  4. Wrote a version for each network and checked them

    A short caption for TikTok, a Reel caption with your cover, a title and description for YouTube. Each one is checked against that network's rules before anything is saved.

    posts_validate

  5. Scheduled it on all three for Thursday at 6 PM

    One post in RobinReach, going out on three networks at the same time.

    posts_create

  6. Check it in RobinReach

    Everything your AI did is in RobinReach: the calendar, the posts and their status. Edit, move or delete anything from there.

Good to know

What it does, and what it doesn't

  • The video can come from your RobinReach media library or a public link. Claude Code, Codex and Cursor can also upload a file straight from your computer.
  • Instagram Trial Reels are supported: your AI can post a Reel to non-followers first and let Instagram share it to followers if it does well.
  • TikTok, X, Bluesky and Threads don't accept custom covers. YouTube custom thumbnails need a verified channel; otherwise YouTube picks a frame.
  • Instagram Reel covers must be JPG images.
  • Want every new TikTok to go out to your other networks automatically? That's Repurposing.

Questions

Frequently asked questions

Can I post one video to TikTok, Instagram and YouTube at the same time?
Yes. In RobinReach one post can go to all three, with its own caption and settings on each. With your AI connected, you ask in one sentence and it sets everything up.

Can ChatGPT post to YouTube Shorts?
It can post your vertical video to YouTube through RobinReach with a title, description, privacy and playlist. YouTube decides on its own which videos appear as Shorts, based on the video's shape and length.

Can it make the video for me?
No. RobinReach doesn't generate videos. Your AI posts videos you already have, and writes everything around them.

Can it pick a cover for my Reel?
Yes, if the cover image is in your media library. Your AI sets it as the Reel cover. TikTok doesn't accept custom covers through its API.

Which RobinReach plan do I need for this?
Connecting Claude, ChatGPT or another AI assistant is included in the Bloom, Thrive and Scale plans. You can start on the free Seed plan and upgrade when you are ready to connect your AI.

Post once, show up everywhere

Connect Claude or ChatGPT to RobinReach once and hand it your next video. Included in Bloom, Thrive and Scale.
