Features

Everything a post needs.
Nothing it doesn't.

✍️

One composer, three voices

Write one description, then tweak it where it matters: an Instagram caption, a shorter Threads text with its topic tag, a TikTok title and description.

🖼️

Carousels that just work

Drop in your photos and put them in order. Up to 10 on Instagram, 20 on Threads and 35 on TikTok. They're converted to JPEG for you.

#️⃣

Hashtags in the right places

Add hashtags once. They go on Instagram and TikTok, skip any already in your text, and stay off Threads, where they don't belong.

⏰

Schedule to the minute

Pick a time and walk away. Every platform publishes on its own, so one hiccup never holds up the others.

✅

Caught before it fails

Live character counts and checks for every platform's limits, so you find out now, not at 9:30 tomorrow. If something does fail, retry just that platform.

🎵

TikTok your way

Post straight to TikTok, or send it to your TikTok inbox as a draft and add a trending sound before it goes live.

How it works

From camera roll to three feeds
in under a minute.

  1. 1

    Connect your accounts

    Link Instagram, Threads and TikTok with each platform's own login. NextDeck never sees your passwords.

  2. 2

    Compose once

    Add photos, write your text, choose where it goes. Preview exactly what each platform will get.

  3. 3

    Schedule and relax

    Hit schedule. Your post goes out on time, and you get a link to each live post.

For developers and AI agents

Let your agent
run the calendar.

NextDeck has a REST API and a built-in MCP server. Hand Claude Code, or any agent that speaks MCP, an API key and it can upload photos, draft posts, check them against every platform's rules and schedule them.
