RecurPost YouTube Post Generator: Free AI Video Descriptions

The RecurPost YouTube post generator is a free AI tool that writes three layers of YouTube platform text for your clients’ channels: the video description, the tag list, and the call to action lines.

Most social platforms treat post text as a caption. YouTube treats it as metadata attached to a specific video. A YouTube description supports 5,000 characters, carries your client’s chapters and links, and earns the viewer’s click in the first lines before the Show more fold. This generator is the YouTube version of RecurPost’s AI social media post generator, and it follows YouTube’s rules. Use it free, with no signup steps.

What it writes

RecurPost YouTube Post Generator Creates Video Descriptions Within 5,000 Characters

RecurPost’s YouTube post generator generates video descriptions based on YouTube’s 5,000-character limit, and it suggests tags based on YouTube’s 500-character tag budget. The output is editable text that you copy into RecurPost’s scheduler to upload, or hand to a client for approval.

5,000
Description limit

YouTube’s maximum description length. The generator writes to the full field rather than stopping after a sentence or two and leaving search context unused.

500
Tag budget

YouTube’s total tag budget. Tags work as topic signals, so the generator favors specific terms over a hashtag style dump.

3
Text jobs per post

The video description, the tag list, and the closing call to action. The generator drafts all three from one topic prompt.

$0
Cost to generate

No account, no email address, and no fee to generate a YouTube description, a tag list, or a closing CTA.

Description limits

YouTube Post Generator Follows Description Character Limits

YouTube allows 5,000 characters for every video description. Most YouTubers write one or two sentences for their channel descriptions and leave the rest of the field unused. RecurPost’s YouTube post generator uses the full character limit, and it writes to the field limits YouTube actually enforces.

Title

100 characters. It carries the video content as shown on a thumbnail, transcribed into words.

Description

5,000 characters. It carries search context, chapters, links, and the CTA.

Tags

500 characters in total. It carries topic signal tags, not hashtag groups.

The Show more fold

YouTube truncates the video description behind Show more after the first few lines. The primary keyword and the topic go before that fold, and the chapters, resource links, and subscribe line go below it. A long-form video such as a 20-minute tutorial needs chapters and resource links, but a Short does not, and writing a 5,000-character description for a Short is not helpful to anyone. RecurPost’s YouTube scheduler carries the same field limits, so the text you write here does not truncate at schedule time.

The three text jobs

The Text a YouTube Post Needs, and the One Thing the Generator Skips

A YouTube post carries three text jobs, and the free generator creates drafts for all three formats from one topic prompt.

Video description

The description tells your clients’ YouTube audience what the video covers, and it gives YouTube the search context to rank it.

The topic tags signal the category within a 500-character limit, which keeps the list specific rather than padded.

Call to action lines

The closing lines ask the audience to subscribe, or they redirect the viewer to a link.

Not community posts

You cannot use the generator to write community posts for your clients. RecurPost follows YouTube’s official API to schedule videos and Shorts, and YouTube’s API does not support community post scheduling. Community posts are handled in YouTube Studio, so any tool page that claims otherwise is making a false promise.

Agency example: RecurPost saves a description template per channel, so an agency managing clients from different industries does not mix up content between them. The SaaS explainer never reads like the restaurant reel.

Step by step

4 Steps to Generate YouTube Shorts and Video Descriptions

RecurPost’s YouTube post generator writes video and Shorts descriptions, tags, and CTAs in four steps, and all four run on this page.

01

Provide the video topic

Describe your client’s video content in one or two sentences.

02

Set the channel tone

Pick a tone that suits the client’s channel and its audience.

03

Add target keywords

Choose the specific keywords you want the client’s video to rank for, based on the target audience.

04

Generate, edit, and copy

Get several description options at once from the free generator. Choose the one that carries the hook in the first line, or edit it. Regenerate as many times as you need until the description suits the client’s video.

RecurPost saves a description structure as a template per channel, and the tool saves agency hours through batch generation rather than one description at a time. A freelancer can generate seven YouTube Shorts descriptions for one client in a single sitting with the same tone, and every description carries the channel’s voice without switching to another tab to check the client’s style doc.

Generator to scheduler

Move Generated Video Descriptions to RecurPost Scheduler for Upload

The video description you generate from the free YouTube post generator is scheduled for posting from RecurPost’s YouTube scheduler. RecurPost is social media management software, and its AI publishing and composer workflow supports every upload field for YouTube videos and Shorts from one place: the title, the description, the tags, the category from YouTube’s 17, the privacy setting and made for kids flag, the playlist assignment, and a custom thumbnail auto-fitted under YouTube’s 2 MB cap.

RecurPost categorizes Shorts and long-form videos from the platform API rather than a toggle. A vertical clip within 3 minutes publishes as a Short, and a 16:9 horizontal video publishes as a long-form video. Client channels connect without passwords: send an email or link invite, the client self-authorizes once through YouTube’s permissions page, and no credential changes hands while you still get the channel connection in RecurPost. Scheduling itself runs inside RecurPost’s publishing automation, so the upload sits in the client’s queue with its fields already set.

Scheduling starts with a 14-day free trial

No credit card. An account manager who runs six YouTube channels can generate descriptions in batches and schedule them in one day, with the category, tags, and thumbnail set per video and YouTube Studio never opened.

The boundary

When the RecurPost YouTube Post Generator Fits, and When It Doesn’t

Where it fits

The generator fits agencies and freelancers who need batches of video or channel description text for many client channels each week. A two-person agency running 12 client channels is the scale where a free text tool stops being a toy and starts saving a working day.

Where it does not

It does not fit clients who need community post text, because RecurPost does not schedule YouTube community posts. It does not fit live stream or Premiere show metadata, which has no native RecurPost scheduling. And it does not fit comment replies, which belong to an engagement workflow rather than a description tool.

What stays in YouTube Studio

Community posts, live stream metadata, and Premiere metadata all stay in YouTube Studio. For the rest of YouTube publishing prep, check RecurPost’s free tools for hashtags, bios, titles, and usernames.

Tones and video types

The Generator Adapts Tone by Channel Niche and Video Type

A gaming channel keeps a casual, in-the-run register, and the generator saves that description structure as a template so it holds across uploads.

A humor-led vlog leads with the punch and keeps the description short, because the viewer came for the video rather than the metadata.

A B2B explainer keeps the vendor-neutral voice a client’s reviewers expect, with the search context and resource links doing the work.

Use the same tool to get different descriptions for Shorts and long-form videos. The generator customizes the write-up based on the video type, so do not expect a four-paragraph description for a Short.

RecurPost YouTube Post Generator FAQs

Is the RecurPost YouTube Post Generator free?

Yes, the RecurPost YouTube post generator is a free AI tool that you use without an account or signup. The generated descriptions, tags, and CTA lines do not include any watermark or usage fee. With a RecurPost account, you access the scheduling workflow that puts the generated descriptions to use.

Yes, the YouTube post generator writes Shorts descriptions as short hook text rather than four-paragraph detail. RecurPost auto-detects the video format when you schedule a clip: vertical videos under 3 minutes are added as Shorts, and 16:9 horizontal clips are posted as regular long-form videos.

Yes, the generator suggests YouTube tags for each generated description within YouTube’s 500-character tag budget. Tags send topic signals to YouTube and to the channel’s audience, so choose specific terms from the generated list instead of a hashtag dump.

A YouTube description should stay within 5,000 characters. Long-form videos benefit from real depth: chapters, resource links, and a subscribe line. The opening lines above the Show more fold carry the hook and the primary topic term, because YouTube truncates the rest behind the fold.

No, RecurPost does not schedule YouTube community posts. YouTube’s API supports video and Shorts uploads on RecurPost, which it publishes with the title, description, tags, category, and thumbnail set at schedule time. To publish community posts, you need to use YouTube Studio.
