Video descriptions
A YouTube description generator that sounds like you.
Most description generators produce generic SEO filler. Klyf learns the voice and structure of the descriptions you already write and drafts a new one to match, for a new video or to improve one you already published.
Free to start. Pro is $19/mo billed annually or $29/mo. Updated September 2026.
How it works
Learned from your own writing, not a template.
Learned from your own writing
Klyf reads the descriptions you already write and matches their structure and tone, instead of the same generic template for everyone.
For a new video or an existing one
Draft one for an idea you have not filmed yet, or rewrite the description under a video that is already live.
You approve every word
Klyf drafts plain text for you to copy and paste. It never posts or changes anything on your channel on its own.
Why generic generators fall flat
A description is part of your voice, not just SEO text.
A generic description generator has never seen your channel, so it produces the same structure for everyone: a summary, a row of hashtags, a subscribe reminder. It reads like it came from a tool, because it did.
Klyf reads the descriptions you already write, the links you already include, and how you actually talk to your audience, then drafts a new one in that same voice, so it reads like you wrote it.

FAQ
Questions, answered.
Is there a free YouTube description generator?
Yes. Drafting a description, for a new video or to improve one you already published, is free, no credit card.
Does it just add keywords and hashtags?
No. Klyf learns the actual voice and structure of the descriptions you already write and matches them, rather than stuffing in generic keywords the way a template-based generator does.
Can it rewrite the description on a video I already published?
Yes. Tell Klyf which upload, and it drafts an improved description grounded in your channel's own style, for you to paste in yourself.
Will it post the description for me?
No. Klyf drafts plain text only. It is read-only on your channel and never posts, edits, or changes anything; you copy and paste the draft yourself.
Is my channel data safe?
Read-only. Klyf reads your analytics and public comments, never touches private videos, and never posts or changes anything. Disconnect and delete anytime.
