Best AI tools to write Instagram Reels scripts in your own voice

• Instagram is your only platform, and you want the niche watching and the scripts in one place: Octupie.
• You post the same ideas on TikTok, LinkedIn, X, YouTube or email as well: CreatorsCompanion.
• You want to spend nothing and you are happy to set it up yourself: Claude or ChatGPT.
• You want the script and the scheduling in one tool: Viuz.
• YouTube is your main channel and Reels come second: vidIQ.
• You work on a marketing team with brand rules to enforce: Jasper.
• Your raw material is a podcast or long recordings: Castmagic.

Prices and features as of November 2026, read on each company’s own site. “Not listed” means we did not find it on their pages, not that the product cannot do it. Scroll sideways on small screens.

Most tools now say they write in your voice. To tell them apart, ask three questions.

• Does it read your actual scripts and captions, or only a description you typed? Adjectives like "friendly" or "bold" tell a model very little. Your own sentences tell it a lot.
• Can you see what it is using? If you can read and edit the samples, you can fix a bad one.
• Does it keep spoken and written voice apart? A Reel is said out loud, so it needs your spoken rhythm. A newsletter sample pulls the draft toward written sentences.

Then test it yourself. Read the draft out loud once. Anywhere you stumble or think “I would never say that” is a place the tool missed. That one minute tells you more than any comparison table, this one included.

1. Get the words of five Reels you are proud of. If you spoke them unscripted, our free Instagram Transcript Generator gives you the text without an account. Fix anything it misheard, and keep your filler words and phrasing.
2. Create a Project. In ChatGPT, select New project in the sidebar, then open the ••• menu and Project settings to add instructions. In Claude, create a project and upload your samples.
3. Paste the instructions below, then add your five scripts.
4. Ask for one script on one topic. Read it out loud and mark what you would never say.
5. Add those corrections to the instructions, so you only make each one once.

You write Instagram Reels scripts in my voice. My real scripts are attached. Before writing, study how I open, how long my sentences are, the words I repeat and how I end.

Rules:
- Write for speech: short sentences I can say in one breath.
- Use my words. Avoid phrases that never appear in my samples unless the topic needs them.
- Give me 3 different hooks, then one script of about 30 to 45 seconds, then one call to action.
- If you need a fact or a personal story you do not have, write [ADD STORY] instead of inventing it.

Never use these words: [your list]

If you post now and then, this may be all you need. The cost is your time: you find what is working in your niche yourself, and you repeat the setup for every new format.

We built it for creators who want the research and the writing in one place. You find a post doing well in your niche, repurpose it into a script in your voice, then reuse the idea as a LinkedIn post, X thread, YouTube script, newsletter or carousel.

New accounts get 2,500 free credits once, which covers five Reels scripts at 500 credits each (using a link as the source adds 100). After that, credit packs start at $10 with no subscription, and Pro is $29 a month with 40,000 credits.

Another tool is the better choice in these cases:

• You want posts scheduled for you. We do not publish or schedule. Viuz does.
• You only post on Instagram and want many accounts watched. As of November 2026, Octupie’s $29 plan watches up to 75 accounts; our $29 Pro plan tracks 15 creators.
• You want to keep paying nothing after your first few scripts. Claude and ChatGPT have free plans.
• You want proof it matches your voice before you start. We have no independent test to show you, so try it on one idea and read the result out loud.
