TikTok Post Generator
RecurPost’s TikTok post generator is a free AI tool that writes a TikTok caption draft. Describe your post, optionally add a keyword, and pick a language and tone. The generator returns an editable caption you copy into your scheduler.
You need no RecurPost account and no login to use it. Freelancers and agency teams draft captions for client TikTok accounts here, then schedule the edited drafts through RecurPost’s social media management software.

What is the RecurPost TikTok Post Generator
The RecurPost TikTok post generator is a free AI writing tool that turns a short description into a ready-to-edit first-draft TikTok caption. It is the TikTok version of RecurPost’s AI social media post generator, tuned to TikTok’s caption format, and 1 of 8 RecurPost free social media tools. Use it across client profiles without an account, a sign-up, or a paywall.
The generator returns one caption draft per run, and you can run it again for another take. The caption may include hashtags, which you keep or cut. Use the draft for your clients’ TikTok videos and photo carousels. A TikTok video carries one caption field and no separate title, so the caption is the main writing job. A photo carousel also has a separate 90-character title field, which this generator does not write.
The generator creates no video and no image, and it publishes nothing to TikTok. Copy the output, edit it, and use it in the composer to schedule and publish through your client’s calendar. A social media manager can draft a week of TikTok video captions this way without a copywriting budget or a client login.
Generator inputs
Describe your post (required), plus an optional keyword, a language (5 options) and a tone (22 options).
API caption limit
TikTok’s Content Posting API caption cap. The generator has no character counter, so check the length in the composer before you schedule.
Free tools
RecurPost publishes 8 free social media tools and gates none of them behind an account.
Cost to generate
No account, no email address, and no paywall between a description and a finished caption.
4 Steps to Generate TikTok Video and Post Captions
RecurPost’s TikTok post generator writes your captions in 4 steps, from blank fields to usable drafts.
Describe the video or the business
Enter 1 or 2 sentences on what the caption should cover. “Taco truck in Denver posting behind-the-counter prep videos” produces a sharper draft than “food content”.
Set a tone
The tone field offers 22 options, from Witty and Casual to Professional and Formal, and it is the client-voice switch. A freelancer running 6 client TikTok accounts changes tone per client so each feed still sounds like its owner.
Generate and rerun if needed
The generator returns one caption draft. Run it again for another take, and keep the one whose first line lands the hook, because TikTok collapses a long caption behind a “more” tap.
Edit and copy the caption
The caption is an AI draft you edit before it goes live. Use the Copy button, then take the finished caption into the composer.
The free generator carries no approval step. An agency that needs a client to sign off on captions before they ship runs that approval inside RecurPost’s scheduling workflow rather than in this tool.
TikTok Caption Limits: 2,200 Through the API, 4,000 in the App
Two figures matter for a TikTok caption. TikTok’s Content Posting API, the route schedulers publish on, caps a caption at 2,200 characters, while the TikTok app itself allows up to 4,000. A caption drafted here is headed for a scheduling calendar, so the 2,200-character API limit is the one that applies. The generator has no character counter and does not enforce either limit, so check the length in the composer, which counts characters as you type.
2,200 characters
The Content Posting API cap, and the limit that applies to captions you schedule.
4,000 characters
The limit when you type a caption directly in the TikTok app. It does not apply to a scheduled post.
Hashtags, @mentions, emojis, and spaces all spend the same caption budget, so the tag count competes with the message instead of sitting outside it. TikTok publishes no figure for how much of a caption shows before the “more” tap, so put the hook in the opening line. RecurPost documents the full per-format rules on TikTok character limits and hashtags, which covers every field this generator does not write.
Move Generated Post Captions from TikTok Post Generator to RecurPost Scheduler
RecurPost’s scheduler starts where the generator stops. Paste the edited caption into your client’s calendar for any connected TikTok account, choose the date, and save. A best-time option can pick the slot for you.
An agency managing 20 client accounts drafts and edits captions per client in the generator, then schedules a week of TikTok posts per account in one sitting from one dashboard. Edited drafts move into RecurPost’s composer, and from there into the TikTok scheduler.
Email or link invites
On the Agency plan, connecting a client’s TikTok account needs no password. RecurPost sends an email or link invite, the client authorizes the connection on TikTok’s own permissions page once, and the account lands in your workspace.
Platform-native post controls
Every scheduled TikTok post keeps its own controls: privacy level, duets, stitches, and the branded content flag, set per post per account.
10 images per carousel
RecurPost’s scheduler follows TikTok’s API and publishes photo carousels of up to 10 images alongside video posts.
About 15 posts per account per day
TikTok’s API ceiling is roughly 15 posts per 24 hours for each account, and RecurPost shows the cap when a client account reaches it.
No credit card. One composer covers a full client mix, so a generated TikTok caption and the rest of the client’s calendar sit in the same publishing queue.
When RecurPost’s TikTok Post Generator Fits You, and When It Doesn’t
Where it fits
- Writing captions for TikTok videos across more than 1 account every week.
- Client accounts that each need their own voice and tone.
Where it does not
- Generating videos, sounds, and effects.
- Managing comments and DMs from TikTok’s inbox.
- Long essay captions, since TikTok collapses a long caption behind a “more” tap.
- Guaranteeing views, because the generator writes captions while views depend on the account, the content, and the timing.
What RecurPost covers
Agencies that need every caption approved before it ships need the RecurPost product and its approval workflow, which is part of the Agency plan. The free generator writes captions and carries no approval workflow. The rest of the set sits in RecurPost free tools.
RecurPost TikTok Post Generator FAQs
Is the RecurPost TikTok post generator free?
Yes. RecurPost’s TikTok post generator is a free AI tool you can use without an account, an email address, or a paywall. Open the page, enter a post description, optionally add a keyword, and set the language and tone. The paid RecurPost product starts where the free tool stops, at scheduling and publishing.
How long can a generated TikTok caption be?
The generator has no character counter and does not enforce a limit, so check the length before you schedule. TikTok’s Content Posting API caps a scheduled caption at 2,200 characters, and the TikTok app allows up to 4,000. RecurPost’s composer counts characters as you type. TikTok publishes no figure for how much of a caption shows before the “more” tap, so put the hook in the opening line.
Does the generator add TikTok hashtags?
It can. The caption may include hashtags, and you keep or cut them in the edit step. There is no hashtag-count setting. Hashtags spend caption characters on TikTok, so keep only the ones that fit the post.
Can I schedule generated captions to TikTok?
Yes. Paste the edited caption into the composer for any connected TikTok account, set the time, and set TikTok’s per-post controls: privacy level, duets, stitches, and the branded content flag, all from one dashboard.
Does the generator create the TikTok video too?
No. The generator writes caption text only. The video, the sounds, and the effects come from TikTok’s own creation tools.
