One product, three ways to open
Your input
Adjustable phone stand made of recycled aluminium. Folds flat, holds any phone, $24.
One paragraph is enough — no prompt engineering.
Option 1
POV: your phone finally stops sliding off the desk 😤 Folds flat, holds any phone, made from recycled aluminium. Link in bio. #desksetup #phoneholder #recycled #techtok #wfhlife
Option 2
I bought three phone stands before this one. Here is why they all failed 👇 Too light, too stiff, or too ugly to leave on the desk. This one is aluminium, so it stays put — and folds flat when you travel. #techtok #deskaccessories #phonestand
Option 3
Stop balancing your phone on a coffee cup ☕️ Recycled aluminium, folds flat, holds any phone at any angle. $24, link in bio. #smallbusiness #desksetup #gadgets

How TikTok captions actually work
TikTok rewards watch time, not caption length. Everything here is about keeping someone in the video long enough for the algorithm to keep showing it.
Hook the viewer, then the reader
Your first frame stops the scroll; the caption gives them a reason to stay. “POV:”, “I tried X so you do not have to”, “Three things nobody tells you” are patterns people already recognise as worth watching.
Write it like you would say it
TikTok captions are spoken-word text. If a sentence would sound stiff read aloud, it reads stiff on screen too. Short, conversational, slightly imperfect beats polished marketing copy.
Keep it under two lines
Captions get covered by the UI and by your own on-screen text. Two short lines plus three to five hashtags is the practical ceiling before it becomes visual noise.
Niche hashtags, not viral ones
#fyp and #viral put you in a pool of millions with no context. #desksetup, #techtok or #smallbusiness reach fewer people who are far more likely to watch to the end.
For sellers shipping to an audience they cannot meet
TikTok copy lives or dies on sounding like a person, not a brand account. If English is not your first language, the safest instinct — write formally — is exactly what kills reach. CopyBoss writes the casual, spoken rhythm TikTok audiences expect, while you keep control of the product facts.
- Casual, spoken tone instead of translated marketing language
- Hooks written for the first three seconds, not for a product page
- Hashtag sets matched to your niche and product category
- Same product brief also produces Instagram and YouTube copy
FAQ
Is the TikTok caption generator free?
Yes. The free tier gives one credit per day — three variations — with no credit card needed. Pro is $9.99 per month for 10 credits a day, or $99 per year for 15.
Does it write hooks or just captions?
Both. Each variation opens with a hook written to hold attention in the first seconds, followed by a short caption body and a niche hashtag set.
Can I write my product details in Chinese?
Yes. Describe the product in the language you think in, and choose English as the output language. Grammar and tone are handled for you.
Will the captions sound like an ad?
They are written in the register TikTok audiences tolerate: first person, specific, and slightly under-polished. You can still switch tone between Friendly, Professional, Witty and Story-driven.
Can I use the same brief for other platforms?
Yes. One credit produces output for the platforms you select — TikTok, Instagram, LinkedIn, X and YouTube — each formatted for that platform rather than copy-pasted.
