How to use it in three steps
1
Pick the platform
Each platform shows a different amount of text before “more”. Postlume knows the limits.
2
Add your idea or keyword
One sentence is enough. A focus keyword helps search.
3
Copy and post
Choose short, standard or detailed. Edit right in the box.
Why Postlume is different
The first line of a description decides whether people tap “more” and how search engines read your post. Postlume writes that first line to stand alone, keeps the text inside each platform limit, and leaves hashtags, chapters and pinned comments to their own tools so nothing is repeated.

Tips for the best result
Lead with the value
Say what people get in the first sentence, because the rest is hidden.
Add hashtags separately
Use the Hashtag generator, then paste them at the end, so they never crowd your first line.
Fill the [ ] parts
Replace [your link] and other brackets with your real links and details.
Frequently asked questions
Is the description generator free?
Yes. The free templates are always free with no sign-up. Digieh AI descriptions, written for your exact content, use 1 credit per run.
Does it add hashtags?
No. Hashtags come from the Postlume Hashtag generator, so your caption and tags never repeat each other.
What does [Chapters] mean in a YouTube description?
It marks where your timestamps go. Make them with the Postlume YouTube chapters generator and paste them there.
Can I use it for blog meta descriptions?
For blog posts and web pages, use Serplume, the Digieh SEO checker, which writes SEO titles and meta descriptions.
Does Digieh save what I type?
No. Digieh does not save your text.
Will it invent facts or links?
No. Where a link or a detail is needed, Postlume writes a placeholder like [your link] for you to fill in.
