Before posting
Check your TikTok before posting it
You can test a TikTok before it goes live. Upload the draft and Viewlify's AI watches it in full, scores the hook, retention, visuals, clarity, sound and shareability from 0 to 10, points at the moments viewers will leave, and tells you what to fix first. The file is never published or kept.
MP4, MOV or WebM, up to about 3 minutes. Results in about 30 seconds.
What the pre-post check catches
A weak opening
If the first 2 seconds do not show why to stay, you will know before your audience swipes.
Dead sections
The exact seconds where nothing new happens, with what to cut.
Unreadable visuals
Text too small for a phone, busy backgrounds, framing that hides the action.
A missing reason to share
Whether the ending gives people a reason to save, send or comment.

Example: a draft reviewed before posting
A sample fitness draft: strong first frame, but a 9 second warm-up that would have lost most viewers.
Average · before posting
Strong first frame, but the warm-up kills retention before you reveal the exercise the title promises.
Score by axis
- Hook6/10
Starting mid-squat with the bar loaded is a strong visual, but the caption text only appears at 0:02.
- Retention4/10
The warm-up section from 0:05 to 0:14 is 9 seconds of nothing new: most viewers will leave there.
- Visual6/10
The gym mirror makes the frame busy, the movement is hard to read on a small screen.
- Clarity5/10
It is not clear which exercise is the one 'nobody talks about' until 0:18.
- Sound7/10
The music is synced to the reps, which keeps energy up.
- Shareability5/10
People who lift would send it to a gym partner if the key exercise came sooner.
What held it back
- 9 seconds of warm-up between 0:05 and 0:14: cut it or speed it up 3x.
- The promised exercise appears at 0:18, after most viewers are gone.
- Busy mirror background makes the movement hard to follow.
Keep this
- The loaded-bar opening frame.
- Reps synced to the beat.
Fixes for this video
- 1
Move the 'nobody talks about' exercise to the first 3 seconds.
You deliver the title's promise before people decide to stay.
- 2
Add the exercise name as on-screen text when it starts.
Viewers watching muted still get the point.
- 3
Film the key set from the side, away from the mirror.
A clean angle makes the form readable and saveable.
Stronger hooks to try
- The leg exercise that fixed my squat in 3 weeks.
- Nobody does this on leg day. Everybody should.
- If your knees hurt when you squat, try this first.
Frequently asked questions
Can I test a TikTok before posting it?
Yes. Upload the draft file (MP4, MOV or WebM, up to about 3 minutes) and Viewlify's AI watches it like a viewer would: it scores the hook, retention, visuals, clarity, sound and shareability, and lists what to fix before you publish. The file is analyzed only, never posted or kept.
Can an AI predict if my TikTok will go viral?
No tool can promise a viral video, the algorithm also depends on timing and who sees it first. What an AI can do reliably is spot what makes people swipe: a slow opening, a dead section, text that is unreadable on a phone. Fixing those before posting is the part you control.
What should I check before posting a TikTok?
Four things: the first 2 seconds show the payoff or a reason to stay; there is no dead section where nothing new happens; on-screen text is readable on a phone; and the video ends on a reason to save, share or comment. The pre-post check scores each of these on your actual video.
Does it compare the draft to my account?
If you tell it your @username, the review is framed against your usual views, so it knows what 'good' means for your account. After you post, Viewlify can also check the real video 48 hours later and compare.
How much does it cost?
The pre-post check is part of the Video check, included in the paid plans: Creator includes 30 AI video analyses a month for $29/month, with a 14-day trial you can cancel anytime.
