- ✓Schedules and auto-publishes to TikTok on Pro
From idea to posted TikTok, in three steps.
Robyn learns how you talk
It reads your content and builds a voice profile: your energy, your slang, the things you would never say.
Give it the video idea
One line is enough. Robyn writes caption options that set up the video and leave the payoff on screen, where it belongs.
Post at peak scroll time
Robyn schedules to your audience’s active hours, and on Pro publishes to TikTok automatically.
Built for how TikTok actually works.
Native short-form writing
TikTok captions are setup lines, not essays. Robyn writes them short, curious, and conversational, tuned to the platform.
One idea, every platform
The same idea becomes a TikTok caption, an Instagram story, and an X post, each written natively, so cross-posting stops looking like cross-posting.
A week in one sitting
Auto-pilot plans and drafts a week of content at once, so daily posting stops being a daily task.
No AI tells
Robyn checks drafts against known AI phrases and rewrites anything that sounds machine-made. TikTok audiences smell canned text instantly.
Frequently asked questions
What is the best TikTok caption generator?
One that writes short, native, hook-first captions in your own voice. Robyn learns your tone from your content first, writes captions built for TikTok’s style, and then schedules and publishes them for you.
Can Robyn post to TikTok automatically?
Yes. On the Pro plan you connect your TikTok account once and Robyn publishes scheduled posts automatically at the times your audience is active.
Are TikTok captions different from Instagram captions?
Very. TikTok captions are short setup lines that create curiosity, while Instagram rewards longer story-driven captions. Robyn writes each natively instead of resizing one caption for every platform.
Is Robyn free for TikTok captions?
Yes. Robyn is free to download on iOS and Android and includes caption generation. Pro ($12.99/month with a 7-day free trial) unlocks unlimited captions, Auto-pilot, and auto-publishing.
Does Robyn write hashtags for TikTok?
Only when you ask. Robyn ships clean captions by default and never stuffs hashtags or watermarks. You stay in control of the final text.
Can it plan a week of TikTok content?
Yes. Auto-pilot proposes a week of post ideas with captions, scheduled at peak times. You approve, edit, or regenerate each one.
