Example: Reels captions for a meal-prep recipe

We ran the generator above once on October 14, 2026 with the input below and copied what came back without editing it. The notes under each result are ours.

The Reel

Overnight oats with three ingredients: half a cup of oats, half a cup of milk and a spoon of peanut butter. I make five jars on Sunday for my work week.

Tone and call to action

Calm, "save this for Sunday"

1. Five jars of overnight oats on Sunday, and my work week is covered. Three ingredients: half a cup of oats, half a cup of milk, and a spoon of peanut butter. Save this for Sunday. #overnightoats #mealprep #sundayprep #easybreakfast231 characters, 4 hashtags. Our pick, and the only one of the five with a line break: the first line stands on its own and the recipe sits under it.
2. What do you make on Sundays to get through the work week? Mine is always the same: oats, milk and peanut butter. Save this for Sunday. #mealprepideas #overnightoats #workweekbreakfast #sundayreset197 characters, 4 hashtags. A question for the comments, but it drops the amounts, which are what someone saving a recipe comes back for.
3. I make five jars at once so breakfast is ready for the whole work week. Half a cup of oats, half a cup of milk and a spoon of peanut butter. Save this for Sunday. #mealprep #overnightoats #peanutbutter #workweek212 characters, 4 hashtags. All three amounts, in the order you'd measure them. A close second.
4. Overnight oats are the easiest thing I prep for work. Just oats, milk and a spoon of peanut butter, stirred into jars. Save this for Sunday. #overnightoats #easyrecipes #peanutbutteroats #breakfastprep202 characters, 4 hashtags. "The easiest thing I prep" compares it with other things we never mentioned.
5. A quick Sunday routine: five jars, three ingredients, and nothing to think about on busy weekday mornings. Save this for Sunday. #sundayprep #mealprepping #overnightoats #simplebreakfast187 characters, 4 hashtags. "Nothing to think about" adds no information. The weakest of the five.

Generated by this tool on October 14, 2026 (Claude Haiku through fal.ai), unedited. A new run gives different results.

Every caption ended with four hashtags, inside Instagram's limit of five. We asked for line breaks in Reels captions but got one in only one of five, so if you want the hook on a line of its own, press return after the first sentence before you post.

How many hashtags can an Instagram caption have?

Five. Instagram's help page Use hashtags on Instagram (read October 14, 2026) says you can use up to 5 tags on a post, and that with more than 5 the comment won't post. Search results and older guides still say 30, and so does Meta's developer documentation for posting through the API, but we'd follow the help center, since it's the page written for people posting in the app.

Instagram doesn't give a best number below five. Its creators FAQ says relevant trending hashtags can help a Reel reach people interested in those topics, and warns: “Don't try to game the system by showing irrelevant hashtags”. If you use the hashtag generator for a Reel, pick five at most from its groups.

How much of a Reels caption shows before more?

Instagram's help pages don't say, and we haven't measured it, so there's no number here. What does have a source: the FTC's Disclosures 101 guide (read October 14, 2026) says disclosures are likely to be missed “anywhere that requires a person to click MORE”. So #ad goes in the first line, which is where the generator puts it.

How do you label a paid Reel?

With the paid partnership label. Instagram's help page on the paid partnership label (read October 14, 2026) says:

• Its branded content policies require the label, with the brand tagged, on organic branded content.
• You can add it only in the Instagram mobile app.
• Until the brand approves you, the label shows without the brand's name.
• Gifts count. Instagram's creators FAQ says anything received from business partners counts, “whether it be money or otherwise”.
