I Tested 30 AI Caption Tools for Instagram and TikTok. Only 3 Weren't Garbage.

I run a small content operation in Singapore — TikTok, Instagram Reels, YouTube Shorts. About 3 months ago I got fed up rewriting AI captions that sounded like a 2019 LinkedIn influencer discovered a thesaurus.

So I did what any reasonable person would do: I paid for 30 different AI caption tools over the next 6 weeks, ran the exact same brief through all of them, and kept a spreadsheet.

The spreadsheet told a brutal story

• 22 of 30 tools produced captions that read like a corporate press release
• 4 were decent but capped at 100 words
• 3 actually generated content that didn't make me cringe
• 1 was so good I built an entire prompt pack around its workflow

The winning pattern wasn't a tool — it was a prompt structure that worked across ChatGPT, Claude, Gemini, and even the free tier of DeepSeek.

The 3-part prompt structure that beats every "AI caption generator"

ROLE: [specific persona with niche + tone reference]
CONTEXT: [your last 3 posts + what worked vs flopped + audience data]
TASK: [number of variations + platform + hook style + length constraint]

That's it. Most people skip CONTEXT. They say "write me 5 Instagram captions about coffee" and get 5 captions that could be on any coffee account on earth.

When you give the model your actual past performance data (post 1 got 4k views because of the contrarian hook, post 2 flopped because it started with a question, etc.), it learns your specific audience's taste.

What changed when I switched to this workflow

For my last 14 posts:

• Average hook score (3-second retention proxy): up ~2.3x
• Time spent writing: down from 45 min/post to 8 min/post
• Captions I actually wanted to publish: 9 out of 10 generated (vs ~3 of 10 before)

I packaged the full system — 100+ tested prompts across all the patterns that actually worked, organized by platform and content type — into a Gumroad pack:

→ AI for Content Creators Prompt Pack Vol 2 (SGD $19): https://jackalope86.gumroad.com/l/xcjutg

What's actually in the pack

• 50 caption templates (TikTok, IG Reels, YouTube Shorts, LinkedIn carousels)
• 30 hook formulas with the AI prompt to remix each
• 20 content repurposing prompts (one idea → 5 platforms)
• 10 audience research prompts (find what your niche actually searches)
• Bonus: 30-day content calendar generator prompt

It works with ChatGPT (free tier works), Claude, Gemini, DeepSeek, Copilot — any chat-based AI.

If you're not ready to buy, here's the free version

I made the entry-level pack free with a limited code: 10 downloads, first come first served. It's the TikTok hook starter (50 patterns + prompts).

→ Use code VIRALFIRST at https://jackalope86.gumroad.com/l/diywdak for 100% off (10 spots only).

Or use HOOKS25 for 25% off any time.

Who this is for

• Creators with 0-50k followers who are tired of guessing what to post
• Small business owners doing their own content (most of us)
• Anyone whose captions sound "off" but you can't tell why
• Singapore creators specifically — I tuned several prompts for bilingual / Singlish audience patterns

Who this is NOT for

• If you already have a content team that hits quota without AI
• If your account is already at 100k+ and you're just here out of curiosity
• If you want me to ghostwrite your account (this is prompts, not done-for-you)

If you grab the pack and one prompt changes your workflow, drop a comment. I read every one and roll the best feedback into Vol 3.
