TikTok script generator for people who film it themselves.
Postiva turns a blog post, article, or pasted text into a short-form video script with a hook, on-screen text, and a matching caption. It writes what you say and what appears on screen. You film it yourself, because Postiva does not record video. The same run also writes the Instagram carousel and caption, the Facebook post, the LinkedIn variants, the X thread, and the newsletter section.
Saying that plainly up front saves everyone time. The script is the part that stops people posting, and that is the part this handles.
No credit card for the trial. Every plan includes all six platforms.
You came for the TikTok script. The rest come with it.
Postiva writes every platform you keep from the same source in a single run. Not one tool at a time, and not one generation each.
Source
One URL or pasted text
yoursite.com/blog/the-post-you-just-published
One generation
Carousel slides, caption, hashtags, and a call to action.
Two post variants: a professional one and a founder voice.
A hook, a five to eight post thread, and a standalone post.
One conversational post written for the feed.
A hook, a spoken script, on-screen text, and the caption.
Script, hook, and on-screen text to film yourself. Postiva does not record video.
Three subject lines, an email-ready body, and a CTA.
Every platform is selected by default, and one generation covers all of them whether you keep one or all six. Instagram carousel slides are rendered and zipped in the same run at no extra cost. AI post images, voiceovers, and lead magnet PDFs have their own separate allowances.
Three steps, start to finished.
- 01
Paste a URL or your own text
Any article, guide, or landing page you have already published works. So does a rough set of notes pasted straight in.
- 02
Postiva reads and restructures it
A written article and a spoken script are not the same shape. The source gets rebuilt around a hook and a spoken rhythm rather than trimmed down.
- 03
You get something you can film today
The hook, the script, the on-screen text lines, and the caption come back together, ready to read off while you record. Every other platform you kept is in the same project.
Everything except the part where you hit record.
TikTok output is text and audio. Postiva is explicit about that in the app too, so nobody generates a project expecting a finished video.
A hook for the first seconds
Written to earn the next three seconds, because that is the only thing standing between your video and a scroll.
The spoken script
What you actually say, structured to be read aloud rather than read off a page.
On-screen text lines
The captions and callouts to overlay while you talk, written as separate lines so you can drop them in one at a time.
The TikTok caption
The post caption to go underneath, written from the same source so it matches what the video says.
An optional AI voiceover
Turn the finished script into an MP3 with an AI voice, then use it as your audio track. Available on TikTok and Instagram outputs.
The writing is not the hard part. The repeating is.
One script from a chatbot is easy. Fifty scripts, on brand, drawn from things you already published, is a different job.
Postiva reads the source URL itself, so you are not pasting an article into a chat and cleaning the navigation out of it first.
The script, the on-screen text, and the caption arrive together and already agree with each other.
Your brand kit tone of voice carries across every script, so a month of videos sounds like one person.
Every script is saved to the project it came from, so you can reopen it, regenerate it, or turn it into a voiceover later.
Built for people who publish every single week.
Postiva earns its place when content is a recurring job rather than a one-off. These are the people who feel that most.
Marketing and SEO agencies
Run every client from one workspace, keep a separate brand kit per client, and send finished work out on an approval link before anything goes live.
Freelancers and consultants
Turn the article you just wrote into a week of posts without opening a design tool or a second AI chat.
SaaS founders
Your changelog, docs, and blog already say something worth reading. This gets that onto the feeds without hiring for it.
Social media managers
Stop rewriting the same idea six times. One source, six native versions, all saved and reopenable.
One source also becomes everything else.
Every tool here runs off the same paste. Pick the platforms you want before you generate and they all come back together.
Every plan includes every feature.
The plan sets how much you generate each month and how much storage you keep, not which tools you can open. Prices are in USD and billed through Paddle.
Starter
$15/month
30 projects a month, with 2 GB of kept assets.
Pro
$29/month
100 projects a month, with 10 GB of kept assets.
Agency

What people ask before they start.
Does Postiva make the actual video?
No. Postiva writes the script, the hook, the on-screen text, and the caption so you can film it yourself. It can generate an AI voiceover as an MP3, and it can render an Instagram carousel into an MP4 slideshow, but it does not record or edit footage.
Do I have to run each tool separately?
No, and this is the part most people miss. Every platform is selected by default when you create a project, and Postiva writes all of them from your source in a single run. One generation covers the whole set, whether you keep one platform or all six, so running the TikTok script, the Instagram carousel and caption, the Facebook post, the LinkedIn variants, the X thread, and the newsletter section costs exactly the same as running just one. Instagram carousel slides are rendered and zipped in that same run at no extra cost. AI post images, voiceovers, and lead magnet PDFs are the exceptions: each has its own allowance.
Does it write TikTok captions too?
Yes. Every TikTok run returns the caption alongside the script, written from the same source so the two say the same thing.
Can I use the scripts for Reels and Shorts?
Yes. The output is short-form vertical video copy, so a hook, a spoken script, and on-screen text work the same on Instagram Reels and YouTube Shorts as on TikTok.
What does the voiceover sound like?
It uses OpenAI text to speech, and the voice is configurable on the workspace. You generate it from a finished TikTok or Instagram output and download it as an MP3.
Is it free to try?
Yes, for 14 days without a credit card. After the trial, plans start at $15 a month and include all six platforms rather than TikTok alone.
Does Postiva post to TikTok for me?
No. You film and upload the video yourself. Postiva writes the script and can hold the post on a content calendar, but it does not publish to any platform.
