Instagram Reels Caption Generator

A browser tool that takes your Reels script and writes three things you can paste straight into Instagram: a full caption with a hook, body, and closing line; a list of 8 to 15 hashtags; and a 3-second on-screen hook line for the video itself.

A strong Reel can flop with a weak caption. Instagram crops captions at around 125 characters in the feed, so the first line has to land alone or viewers tap away. Writing dozens of captions manually for a weekly posting cadence is tedious, and most creators end up reusing the same generic structures. This tool gives you a fresh, scroll-stopping caption every time without the friction.

No. The Reels Caption Generator runs entirely in your browser, so there is nothing to install, download, or sign up for. It works on macOS, Windows, ChromeOS, and Linux as long as you can open the page.

Aim for 80 to 180 words. The first 125 characters show before the "more" link in the feed, so the hook line has to land alone. The tool always front-loads your strongest line so the cropped preview earns the tap.

Instagram caps at 30 but recent guidance is 8 to 15. The tool returns a mix of broad, mid-tier, and niche hashtags, so you get reach without looking spammy. Stuffing 30 hashtags is an old playbook that hurts more than it helps now.

No. The model uses your script as the source of truth, keeps emoji minimal, and avoids the corporate "save this", "comment below" closings that signal AI or PR. Paste without editing.

Reels and TikTok captions follow different rules. Reels rewards longer captions (80 to 180 words) and 8 to 15 hashtags, while TikTok is shorter (under 80 characters per line) with 5 to 10 hashtags including #fyp. If you cross-post to TikTok, try the TikTok Caption Generator so the caption matches TikTok culture instead of Instagram’s.

The Caption Generator writes the text. For the video, use the Camera Recorder, or the Teleprompter & Camera Recorder if you want to read a script naturally while filming. Both are free, browser-based, and export an MP4 you can post to Reels.
