Caption & Hashtag Helper
Describe the post, pick a platform and a tone, and get a draft caption with hashtag ideas. Switch to the word counter when you just need a tally.
How to use this tool
- Enter a short topic or a few keywords that describe the post or video.
- Choose a category, platform, and tone, then generate drafts.
- Edit the text if you like, copy it, or generate another variation.
- Use the Word counter tab to paste any script or caption and see character, word, sentence, and paragraph counts.
Frequently asked questions
Is this an AI writing API?
No. Drafts are built from templates and a local hashtag list in your browser. Nothing you type is sent to a writing service or to ToolNest.
Will these hashtags guarantee reach?
No. Treat them as a starting set. Mix specific tags with a few broader ones, and drop anything that does not match the post. Platforms change how tags work over time.
What limits does the counter use?
The helper shows common length guides: around 2200 characters for Instagram captions, 4000 for Facebook posts, 100 for a TikTok caption you want fully visible, 100 for X, and 100 for a YouTube title with 5000 allowed in the description.
Can I use the drafts commercially?
Yes. The generated text is yours to edit and post. You are still responsible for claims, tags, and disclosures in the final copy.
