Check the caption and hashtags

A fine slide falls flat under a caption cut off at 125 characters, or drowned in twelve hashtags of which the platform will keep five. joli.studio knows each platform’s limits and shows them to you while you write, not after the rejection.

Where the caption is written

In the right-hand panel of the slides editor, the Caption section. A Text field — capped at the platform’s character limit — and, below it, the Hashtags area, where you type a word followed by a space, a comma or Enter.

The hashtags label repeats the platform’s advice: “Hashtags · 4 recommended” on Instagram, 3 on LinkedIn and Pinterest, 2 on Facebook, 1 on X and Threads, 4 on TikTok. Past the accepted maximum, the extra hashtags turn amber in the list.

The two counters

As soon as the caption isn’t empty, two lines appear under the field, each with a green check or an amber triangle and its counter:

• Hook visible before “more” — the first line, compared with what the platform shows before folding: 125 characters on Instagram and Facebook, 210 on LinkedIn, 100 on TikTok, 50 on Pinterest, all of it on X and Threads.
• Hashtags: Instagram keeps 5 — how many you put in, against the maximum: 5 on Instagram, LinkedIn and Facebook, 3 on X, 1 on Threads, 10 on TikTok, 20 on Pinterest.

If the whole caption goes past the platform’s limit, a third line, in red, says so with both numbers: “Caption too long: 2,412 of 2,200 characters (Instagram).”

The Checks panel

The Checks section, in the Post tab, holds the post’s full list: caption, hashtags, slides, images, alt text. When all is well, it reads All clear. Otherwise it counts by severity — “1 blocking · 3 to fix · 2 tips”.

Every line carries its remedy:

• a mechanical fix, applied in one click: “Keep the first 5” for too many hashtags, “Clean up” for hashtags that are duplicated, empty or badly written;
• or Fix with the assistant, which hands the instruction to the editor’s chat — with, like any AI action, its cost before and after, and an undo.

A check that doesn’t apply to you can be set aside: the Dismiss this check button files it “for this session”, and a discreet “2 dismissed · Restore” brings it back.

Copying when it’s time to publish

Three routes:

• the Publish window, at its “The texts” step, hands you the caption, the hashtags and the alt texts one by one, in the order the platform asks for them (see publish a post);
• in the Caption section, the copy icon takes the caption and its hashtags;
• in the Publish button’s menu, Copy section: The caption and hashtags, The hashtags alone, or The alt texts.

An export’s ZIP archive contains caption.txt in any case: the caption is already in there, ready to paste.
