A hashtag library is a named set of hashtags you can reuse. They exist for two reasons: so you don’t retype the same twenty tags, and so Ocoya’s AI uses your hashtags rather than making some up. You create and manage them from the post editor — there’s no separate page to visit.

​
Create one

In the post editor, open Manage hashtags. That lists your existing libraries and lets you add one without leaving the post you’re writing.
1

Create a new library

From the hashtag panel, choose to create one.
2

Name it

Between 2 and 30 characters. Name it after when you’d use it — Product launches, Recruiting — rather than after its contents.
3

Add the hashtags

Type them in, separating with a space, a comma or a #. Press Enter to add one.You don’t need to type the # — Ocoya adds it. Duplicates are dropped automatically, so pasting an overlapping list from somewhere else is safe.
A library needs a name and at least one hashtag before it will save. Libraries belong to the brand, so each brand keeps its own. Editing one changes it everywhere it’s used from that point on; posts already published are untouched.

​
Why it matters for AI posts

This is the part worth knowing. When you pick a library while generating a post, Ocoya is instructed to use only hashtags from that library — it won’t invent new ones, rewrite them, translate them, or change them between singular and plural. #RunningShoe stays #RunningShoe and doesn’t quietly become #RunningShoes. That matters because a hashtag that’s one character off is a hashtag nobody follows. With no library selected, the AI adds no hashtags at all unless your prompt explicitly asks for them. Generating hashtags costs 1 credit, the same as any other AI action. See What are credits?

​
Choosing what goes in one

A library works best when every tag in it is appropriate for every post you’d use it on, because the AI picks from the whole set. A library mixing product tags with recruiting tags gives the AI room to pick the wrong ones. Several small, specific libraries beat one large general one.

Labels

The other reusable asset — for organising posts, not tagging them publicly.
