Caption creator & character preview
Write or generate a caption with AI, compare character counts across six platforms, and preview your opening lines. Free, with no login required.
How it works
- Type or paste a caption to see character counts for Instagram, Facebook, LinkedIn, TikTok, X, and Pinterest.
- Optionally open AI caption creator, enter a short topic, choose a platform and tone, and complete the security check.
- Review the AI draft, edit any claims or details, and compare the platform previews before copying.
- Copy your finished caption into the platform or scheduler. Nothing is published by this tool.
Tips for a better post
- Lead with one clear idea and put the useful information in the opening lines.
- Choose one call to action and use relevant keywords naturally. Avoid stuffing hashtags into every sentence.
- Treat AI output as a first draft. Check facts, names, links, tone, and length before publishing.
Frequently asked questions
Is the AI caption generator free?
Yes, within a limited daily allowance: up to 5 generation attempts per network and 100 across the site each day. Limits reset at 00:00 UTC. Failed attempts may count. Manual writing and previews remain available when AI is at capacity.
Are my captions stored?
Manual text stays in your browser tab. When you click Generate, your topic, selected platform, and tone are processed by Cloudflare Workers AI. Our tools do not save the topic or generated caption. Do not include sensitive information in AI prompts.
Are the character counts and previews exact?
These are planning guides, not guarantees of platform acceptance or exact feed layouts. X uses weighted counting, including shortened URLs and emoji. Other counts use UTF-16 units conservatively. Platform rules, native apps, API publishing, and account types can differ; confirm in your publishing app.
Which platforms can I preview?
Instagram, Facebook, LinkedIn, TikTok, X, and Pinterest. The same draft is shown across all six so you can spot long captions and weak opening lines quickly. AI creates one draft for your selected platform at a time.
What usage information can admins see?
Daily totals for tool visits, splits, download actions, preview sessions, copies, and AI attempts, successes, and errors. Admin reports contain no images, filenames, captions, prompts, raw IP addresses, or individual browsing histories.
Privacy and usage
Images and manual captions stay in this browser tab. Nothing is uploaded when splitting or previewing. AI sends only your topic, platform, and tone for processing by Cloudflare Workers AI; we do not save prompts or generated captions. We keep aggregate usage counts and daily rotating, hashed network identifiers for abuse prevention, cleared daily. Closing or clearing the tool removes its working content; downloaded files remain on your device.
