Best AI tools to write Instagram Reels scripts in your own voice
The best AI tool for writing Instagram Reels scripts in your own voice depends on what else you post. If Instagram is your only platform, Octupie is built for exactly this: it learns from your own Reels and watches your niche for you. If you also post on TikTok, LinkedIn, X, YouTube or email, CreatorsCompanion writes all of them from one voice setup. If you would rather pay nothing and do the setup yourself, Claude or ChatGPT with five of your real scripts in a Project is a solid start.

To find viral posts in your niche, compare each post's views with what that account usually gets. Raw view counts mostly show who has the biggest audience, while a post at 20 times its creator's normal numbers shows an idea that travelled. You can do this by hand with a spreadsheet and 20 accounts, or use a tool that ranks posts for you: Virlo or Sandcastles for short-form video across platforms, vidIQ for YouTube, Taplio for LinkedIn, and the free niche check on CreatorsCompanion for a first look at TikTok and Instagram.

A Claude or ChatGPT connector lets the assistant use another app from inside your chat, so you can ask it to pull your analytics, find viral posts, write a draft in your saved voice or schedule a post without switching tabs. To set one up in Claude, open Customize, then Connectors, and connect a listed app or add its server URL. In ChatGPT, open Plugins and install a listed plugin, or add a custom MCP server if your plan allows it. You sign in once and approve what the app can do.

To get an AI to write like you, give it real samples of your own writing, tell it what to keep and what to avoid, and correct its drafts until the same corrections stop coming up. ChatGPT or Claude can do this on their free plans if you keep your samples in a Project. Tools built for the job save the setup by reading your posts for you: Taplio for LinkedIn, Octupie for Instagram Reels, Jasper for marketing teams, and CreatorsCompanion across Reels, TikTok, LinkedIn, X, YouTube and email.
