RecurPost YouTube Post Generator: Free AI Video Descriptions
The RecurPost YouTube post generator is a free AI tool that turns a short description of your video into one editable video description draft. You describe the video, and you can add a keyword, a language and a tone. It is built for freelancers and agencies who write description text for client channels.
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, can carry chapters and links, and earns the viewer’s click in the first lines before the Show more fold. This page is the YouTube entry of RecurPost’s AI social media post generator. The generator does not count characters or enforce YouTube’s limits, and it writes a general social post from your description, so check the length and edit the draft into description form before you use it. No sign-up is needed.

RecurPost YouTube Post Generator Writes One Editable Video Description Draft
You describe your video, and the generator returns one video description draft. YouTube’s description field takes up to 5,000 characters, but the generator does not count characters or stop at a limit, so check the length before you paste it. The generator does not write a separate tag list or call to action. Copy the draft into RecurPost’s YouTube composer to schedule it, or send it to a client to review.
Description limit
YouTube’s maximum description length. The generator does not fill or enforce it, so a draft can be much shorter than 5,000 characters.
YouTube tag limit
YouTube’s total limit for tags on one video. The generator does not return a tag list. Tags are set in RecurPost’s YouTube composer when you schedule.
Draft per run
One video description draft each time you press Generate Post. Run it again for another version.
Cost to generate
No account, no email address, and no fee to generate a YouTube video description draft.
Know YouTube’s Field Limits Before You Paste
YouTube allows 5,000 characters for every video description. The generator does not count characters or cap its output, and in testing it returned short drafts, so check the length yourself. RecurPost’s YouTube composer counts characters as you type when you schedule the video.
Title
100 characters. The generator does not write a title. Set it in the composer, where it fills from your post text if you skip it.
Description
5,000 characters. This is the field the generator’s draft is written for.
Tags
500 characters in total. Set in the composer. The generator does not return a tag list.
The Show more fold
YouTube truncates the video description behind Show more after the first few lines. Put the main topic before that fold, and put chapters, resource links and a subscribe line below it. A long-form video such as a 20-minute tutorial needs chapters and resource links, but a Short does not. The generator does not place the fold for you, so read the first lines of the draft before you use it. RecurPost’s YouTube scheduler carries the same field limits when you schedule the video.
What the Generator Writes, and What Stays in the Upload Fields
A YouTube upload has separate text fields. The free generator drafts one block of text from your description and returns it as a single draft. It does not fill the fields separately.
Video description
The one block the generator returns. YouTube’s description field takes up to 5,000 characters. The generator does not invent chapters or links, so put the details you want in the description box.
Tag list
The generator does not return a separate tag list. In RecurPost’s YouTube composer, tags are their own field of up to 500 characters in total.
Call to action lines
There is no separate call-to-action field. If you want a subscribe line or a link, ask for it in the description box or write it in while you edit the draft.
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.
Agency example: an agency writing for clients in different industries can describe each video in the client’s own words, choose a tone and a language for each run, and edit every draft before it goes to the client.
4 Steps to Generate YouTube Shorts and Video Descriptions
RecurPost’s YouTube post generator writes one video description draft in four steps, and all four run on this page.
Provide the video topic
Describe your client’s video in one or two sentences. This is the only required field and needs at least 10 characters.
Pick a tone
Choose one of 22 tone presets, from Witty and Casual to Authoritative and Urgent, or leave it empty.
Add a keyword and language
Open Optional Fields to enter one keyword for the draft to include where it fits, and to choose English, French, Spanish, German or Italian.
Generate, edit, and copy
Press Generate Post to get one draft. Copy it with the Copy button, edit it in your own editor or in RecurPost’s composer, and run the generator again if you want a different version.
The tool writes one draft per run, so a freelancer preparing descriptions for seven Shorts runs it once per video. Keep the same tone selected across runs, then edit each draft to match the client’s style guide.
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 up to three minutes publishes as a Short, and a 16:9 horizontal video publishes as a long-form video. On the Agency plan, 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.
No credit card. An account manager who runs six YouTube channels can draft each description here and schedule the videos in one day, with the category, tags, and thumbnail set per video and YouTube Studio never opened.
When the RecurPost YouTube Post Generator Fits, and When It Doesn’t
Where it fits
The generator fits agencies and freelancers who want a quick first draft of video description text for client channels, which they then edit and schedule.
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.
Pick a Tone and Add Your Niche Detail
A gaming channel can pick Casual, Excited or Funny. Add the game and the moment to the description so the draft has specifics.
A humor-led vlog can pick Funny or Witty. Describe the premise in the description box, because the generator only knows what you tell it.
A B2B explainer can pick Professional, Informative or Authoritative, and use the product category as the keyword.
The generator has no Short or long-form setting. Say in the description box whether the video is a Short, and check the length of the draft yourself.
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 draft carries no watermark and no usage fee. With a RecurPost account, you access the scheduling workflow that puts the generated description to use.
Does the tool write descriptions for YouTube Shorts?
Yes, but it has no Short or long-form switch. Describe the video and say it is a Short, and the draft is written from that. When you schedule in RecurPost, a vertical clip up to three minutes publishes as a Short by YouTube’s own format rule, and a 16:9 horizontal clip is posted as a regular long-form video.
Can the generator create YouTube tags?
No. The generator returns one description draft and does not return a separate tag list. Tags are their own YouTube field, with up to 500 characters in total, and you set them in RecurPost’s YouTube composer when you schedule. Choose specific topic terms rather than a long hashtag-style list.
How long should a YouTube description be?
A YouTube description can use up to 5,000 characters. The generator does not count or cap characters, so check the draft’s length before you paste it. 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.
Does RecurPost schedule YouTube community posts?
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.
Try the YouTube Post Generator for Client Channels
Use RecurPost’s YouTube post generator to write your clients’ long-form video and Shorts descriptions.
