Schedule social media posts with every network's options

When you schedule social media posts, things rarely break at the schedule button. They break earlier: the idea is in one doc, the script in another, the caption in a chat and the video on someone’s laptop. In HeyMark all of that lives on the post that eventually goes out, with each network’s options in view, and you schedule it to Instagram, TikTok, LinkedIn, Facebook or YouTube. If you work with an AI assistant, you can also schedule from Claude or ChatGPT.

You plan where it gets published

A scheduling app doesn’t help much if the work is still spread across five places. In HeyMark every post keeps the idea, the script and the caption together. It has a status, a date and an owner; the team comments and uploads versions right there, and the activity log shows who did what. You see the month as a calendar or as a board by status. When you connect your accounts, HeyMark pulls in what you’ve already published and lays it out on the calendar with its video, caption and numbers. Anything someone on the team posts straight from Instagram shows up too, so the calendar shows what actually went out, not just what someone scheduled.

A social media scheduler that knows each network

You pick the destination and HeyMark shows you that platform’s limits before you write too much. Here’s what you can schedule on each network today:

Each post takes up to 35 files, and you can trim video without leaving HeyMark.

Scheduling to TikTok and LinkedIn without redoing the work

What you built for Instagram you duplicate for TikTok in one click, without re-uploading the file or copying the caption. Then you adjust what’s specific to TikTok, like the title, the privacy or whether you allow duets, and schedule it for the time that works. On LinkedIn, a carousel goes up as a PDF document, and you mention the people and companies involved in the text.

If you work with clients, the approval link comes on every plan, so sign-off happens before you schedule. How that works across several brands: HeyMark for agencies.

Scheduling from Claude or ChatGPT

If you already work with an assistant, you don’t need to open HeyMark to schedule. With the MCP server, free on every plan, Claude or ChatGPT create the post, upload the file, duplicate it and schedule it with your permissions. What it can do in each format is on the Instagram MCP page.

Use HeyMark with the brand [brand name].

Take the Reel draft [draft title] and duplicate it for TikTok, with the same file and the same caption.
Before scheduling, show me both posts with their network, format, caption, date, time and time zone.
Once I approve, schedule them for [Thursday at 7:30 p.m. Eastern].

Scheduling runs directly, with no preview. That’s why the prompt asks to see the date, time and time zone first. Publishing right away does ask for your confirmation. In ChatGPT, creating or publishing requires developer mode. And if you’d rather not write the caption, HeyMark’s AI agent proposes it in your brand’s voice for you to approve.

What happens after it goes out

Scheduling isn’t the end. Before the post goes into the queue, you can attach a comment automation to it: anyone who comments the keyword gets a public reply and a DM, with no credits spent. Once the post is live, comments and messages land in the inbox, where you or Mark answer them in your brand’s voice, and the post collects its metrics: reach, likes, comments and engagement. It all stays on the same post, next to the idea and script it started from.

When another tool fits better

HeyMark doesn’t publish to X, Pinterest, Threads, Bluesky or Google Business Profile. If you need them, Metricool covers all of those (X is a paid add-on) and Buffer includes X, Threads and Bluesky among its 12 networks. Both have free plans and HeyMark doesn’t: it has a 14-day trial. If you only schedule a few posts and don’t reply to comments or messages, Metricool’s free plan (1 brand, 20 posts a month, no LinkedIn) or Buffer’s may be enough. To compare more options, see the Buffer alternatives.

How to schedule social media posts with HeyMark

1. Start the 14-day trial and connect your accounts. HeyMark pulls in what you’ve already published.
2. Create a post with the idea, script and caption, and give it a date and an owner.
3. Pick the network and format, upload the files and check that network’s options.
4. Schedule it. If it’s also going to TikTok, duplicate it first and adjust the title.
