ChatGPT
ChatGPT is OpenAI's chat assistant, and it writes a good first draft of a video script. You describe the video, then ask for changes.
- Best for: drafting any video script from a conversation.
- Strengths: it rewrites, shortens and gives you several versions when you ask. On Plus, you can save the details of your product once, so you do not paste them in every time.
- Price: a free plan with unlimited text chats. In the US, Go is $8 a month, Plus is $20 a month and Pro starts at $100 a month.
- Tradeoff: a vague request gives a generic script, and it does not time the script, scroll it or make the video.
Jasper
Jasper is a marketing writing tool that learns your brand voice. You teach it once, then ask for scripts in chat, from a template or with its Video Script agent.
- Best for: marketing teams whose video scripts must sound like the rest of their copy.
- Strengths: a Video Script agent on Pro writes scripts in your brand voice. On Pro you also save 2 brand voices, 5 documents about your product and 3 descriptions of your customers, and Jasper uses them when it writes. Business, priced on request, has no limit on brand voices.
- Price: Pro is $59 a month per person billed yearly, or $69 monthly. There is no free plan, but there is a 7-day free trial.
- Tradeoff: it has the highest starting price here, $59 a month per person, and it gives you text only, so you film and edit the video yourself.
Copy.ai
Copy.ai is a writing chat for small teams. In one place, you can switch between the AI behind ChatGPT, Claude and Gemini.
- Best for: small teams that want one shared writing chat.
- Strengths: the chat has no word limit, and the Chat plan lets 5 people use it.
- Price: Chat is $24 a month billed yearly, or $29 monthly. No free plan is listed.
- Tradeoff: there is no free plan, you write scripts in the general chat rather than a video tool, and the next plan, Growth, is $1,000 a month.
BigVU
BigVU is a phone app that writes your script and shows it on a teleprompter while you record. It then helps you edit and post the video.
- Best for: solo presenters who write, record and post from one phone app.
- Strengths: the teleprompter and AI scripts are on every plan. Captions start on Starter. AI Pro adds eye contact correction, background replacement and stock clips placed over your video for you.
- Price: a free plan with 500 AI credits a month. Starter is $12 a month or $149 a year, and AI Pro is $19 a month.
- Tradeoff: the free plan exports 720p with a watermark and stops recordings at 9 minutes.
Speakflow
Speakflow is a teleprompter in your browser that scrolls as you speak. You write or paste the script and press start.
- Best for: teams that write scripts together and record at a desk.
- Strengths: scripts sync across your devices, and a team can write, organise and share them. Plus adds AI writing and recording in the same tab.
- Price: a free plan with the teleprompter, where you type or paste the script yourself. Plus, with the AI writing tools, is $19 a month.
- Tradeoff: the free plan does not write scripts with AI, and scrolling that follows your voice is limited on it.
InVideo
InVideo writes a script from your prompt and turns it into a video. It uses stock clips and an AI voice, so nobody films.
- Best for: teams with no footage and nobody to film.
- Strengths: you can also paste your own script. It can make new clips with AI, and you can fix any scene on a timeline.
- Price: Basic is $9 a month, billed yearly. The pricing page shows no free plan.
- Tradeoff: nobody says the script to camera, and your own product is not the centre of the video.
Cutroom
Cutroom does not write scripts. It edits the video you film from your script into a finished vertical video.
The site also has a free script template, a script timer and a teleprompter. You do not need an account to use them.
- Best for: people who read their script to camera and want the finished video back.
- Strengths: it cuts the video, adds captions timed to your voice, puts b-roll on the words you pick and adds a hook. It drafts opening headlines you can pick or rewrite.
- Price: your first video is free, with no card, and you have 7 days to make it. The Lite plan is $19.99 a month for 1,250 credits.
- Tradeoff: it needs a filmed video of up to 3 minutes, and it only makes vertical (9:16) video.

How to get a good video script from an AI writer
Give the AI writer the facts about your product first, then tell it how the script will be spoken.
- Paste in what you are offering, one fact or number that backs it up, and the question customers ask most.
- Ask for a script written to be spoken, with short sentences, plain words and one idea per line.
- Give a word count as well as a length, such as 130 words for 60 seconds.
- Ask for five different opening lines, and pick the one that names the viewer's problem fastest.
- Read the draft out loud before you film, and change every line you trip over.
When a human scriptwriter is the better choice
For most videos, an AI draft that you edit is faster. A human scriptwriter is better in three cases.
- Your videos make health, legal or money claims. A writer who knows the advertising rules for your field can keep every line within them.
- Your videos depend on a strong personal style, like a well-known coach's. A human writer can interview you and write the way you actually talk.
- Your video is a short film with several scenes and speakers. A scriptwriter plans who says what in each scene.
Which one should you choose?
Choose by what you need after the draft.
Which one should you choose
Choose ChatGPT if you want a free first draft of any script and will edit it yourself.
Choose Jasper if you want an agent made for video scripts that writes in the same brand voice as the rest of your marketing.
Choose Copy.ai if you want one writing chat shared by a team of up to five people.
Choose BigVU if you want to write the script and read it from a teleprompter on your phone.
Choose Speakflow if you want a browser teleprompter that scrolls with your voice.
Choose InVideo if you want the script turned into a stock-footage video and nobody will film.
Choose Cutroom if you have filmed yourself reading the script and want a finished vertical video with captions, b-roll and a hook. Your first video is free.
Questions people ask
- What is the best AI script writer for video?
- ChatGPT is the best for most people, because its free plan writes a good first draft. Jasper is best if every script must match your brand voice, and Copy.ai if a small team shares one writing chat. Choose BigVU or Speakflow if you want a teleprompter, and InVideo if nobody will film.
- Can ChatGPT write a video script?
- Yes, and the free plan is enough. Tell it the product, the viewer, the format and a word count, then ask for five opening lines. It does not time the script, scroll it or make the video.
- Which AI script writers are free?
- ChatGPT and BigVU. ChatGPT's free plan has unlimited text chats, and BigVU's free plan writes scripts with 500 AI credits a month. Speakflow's teleprompter is free, but its AI writing needs Plus at $19 a month. Jasper has a 7-day trial, and Copy.ai and InVideo list no free plan.
- How long should a video script be?
- About 65 words for 30 seconds and 130 words for 60 seconds, at a normal pace of about 130 words a minute. Ninety seconds is about 195 words. Read it out loud once before you film.
- What makes a good script for a short video?
- A first line that names the viewer's problem, one idea, and one example or number that backs it up. End by telling viewers what to do. Use short sentences and plain words, and keep to the word count for your length.
- Does Cutroom write the script for me?
- No. Cutroom edits the video you film. The site has a free script template, a script timer and a teleprompter, with no account needed. In the editor, Cutroom drafts opening headlines that you can pick or rewrite.
- Do I need Cutroom if I only need a script?
- No. For the words, use ChatGPT, Jasper or Copy.ai, and if nobody will film, use InVideo. Cutroom is for the next step: you have read the script to camera, up to 3 minutes, and want a finished vertical video.
Film the script you wrote and get the finished vertical video back. Your first video is free.
