Instagram has no button for downloading another profile's captions
You open a creator's profile in your niche, copy the caption from the first post and paste it into a Google Doc. Same with the second, then the third. By post 30, the file is still called "Untitled document (3)", it's huge and it hasn't produced a single conclusion. Half the Reels have a caption that's just an emoji and "link in bio".
The short answer if you want to extract Instagram captions: the platform doesn't export captions from other people's profiles. For your own profile, there's the account data download. Below are the options that actually exist, plus one route that gives you the text already analyzed, along with the speech from the videos and the slides from the carousels.
Three ways to get the captions, and where each one gets stuck
For each option, look at three things: how long it takes, which profiles it works on and what risk it puts on your account.
- Copy by hand. Works on any profile, but it takes hours and you end up with the caption only. What was said in the Reel and written on the slides is left out.
- Download your account data. In Accounts Center, the "Download your information" option generates a file (HTML or JSON) with your posts and captions. It only works for your own profile, so it doesn't help you study references.
- Third-party extensions and scrapers. They usually ask for your login, may go against Instagram's terms, put your account at risk and stop working when the layout changes.
Your password stays with you
Don't hand your Instagram login to extensions or sites you don't know. A spreadsheet of captions isn't worth the risk of losing access to your account.
A caption alone shows only part of the post
Three common posts in any niche:
- A Reel with the caption "save for later 👀". All the content is in the speech.
- A carousel where the argument sits on slides 2 to 7, while the caption just repeats the title.
- A long-caption post where the hook is in the first line, the only one visible before "more". In the spreadsheet, it becomes just the start of a paragraph, and you lose the sense that this line was what kept people reading.
Anyone who extracts only the caption concludes that the profile "writes little" or that "emojis drive engagement", and misreads what works. That's why Creathoria's profile analysis reads the image, the carousel slide by slide and the video, through the caption or the transcript of the speech.

Step by step: extract and analyze a profile's captions in Creathoria
- Create the brand and fill in the briefing. With your niche and audience defined, the AI reads the references with your focus in mind.
- In Reference profiles, add the @ of the Instagram profile.
- Choose how many posts to load and which ones to analyze.
- Click Analyze and build dossier. The AI reads the caption, the video transcripts and the carousels slide by slide.
- Open the profile's dossier. It includes themes, hook patterns, structures, formats, tone, ranking and a summary of each post.
- Use the profile chat to get into the details. It talks to the dossier and fetches the full transcript of a post when it needs to. Conversations stay in the history and can be picked up again.
Instagram is on every plan. TikTok and LinkedIn start with Creator. To analyze a single post, paste the link into Analyze and recreate, on the site or in the app. If you work in Claude or another agent, the Creathoria skill analyzes profiles right in the conversation. To go from one specific Reel to the script, read transcribe Reels: from link to analyzed script.
Seven questions to ask the captions once you've extracted them
The extracted text only becomes a content idea when you ask it questions. These seven work in the profile chat or as a checklist for reading the dossier:
- How does the first line open: with a question, a number or a controversial claim?
- Which call to action shows up most, and in what type of post?
- What does the creator call the audience?
- Which themes repeat in the top-ranked posts?
- In the best-performing formats, is the caption long or short?
- What's said in the speech that doesn't appear in the caption?
- Which subjects does this profile never touch? That could be the gap you fill.
In the chat, write the way you'd talk to a colleague: "In the five top-ranked posts, what does the speech say that the caption doesn't?"
When you paste raw text into a generic chat, the answer tends to be a generic summary, because the AI has no hook, format or ranking to lean on. The reason is explained in how to use AI for social media content research. To compare with what performs on your own profile, see how to find your best-performing social media content.
In your own captions, what's worth extracting is your voice
For a backup, the route is Instagram's data download. To study your own profile, Creathoria has Own profile analysis: what worked, your real tone and the themes you've already covered. All of it feeds into planning.
In Post personality (web), the AI reads the actual text of your posts and extracts your spoken and written voice, rhythm, expressions, catchphrases and the way you address your audience. That goes into every piece. With Faithful reproduction on, the intensity matches your posts, but the tone of voice from the briefing always wins.
In practice, new pieces come out sounding like you and don't read like AI text. To take this further, read social media content strategy built from your own posts.
Use other people's captions to understand the formula, then write the rest your way
In Analyze and recreate, the Create post with AI option lets you choose what to do with the post: react, inform, counter, go deeper, apply it to your niche, use the formula with a different subject, recreate it in the brand's voice or adapt it for the brand. The AI takes the mechanism and never copies the author's phrases, numbers or stories.
The dossiers of your references and of your own profile feed the planning automatically. Each content idea comes with a theme, audience question, hook, structure, format and goal.
So you don't have to redo the extraction every month, the Reference Radar (starting with Creator) summarizes what your references posted, at the frequency you choose: trends, ideas with a hook for your brand, hooks to test and posts to study. The summary shows up on screen, in the bell and by email. For the ethics side, see how to research reference creators without copying anyone.
Frequently asked questions
Can I download another Instagram profile's captions into a file?
Instagram doesn't offer that export for other people's profiles, and the tools that promise it ask for your login and put your account at risk. In Creathoria, you add the @ as a reference profile. The AI reads the posts you choose and organizes everything in the dossier, and the profile chat fetches the full transcript of a post when you need it.
How do I download the captions from my own profile?
Use the "Download your information" option in Instagram's Accounts Center. You get a file with your posts and captions. To study your voice and what worked, use Own profile analysis and Post personality in Creathoria.
Can I get what's said in Reels, beyond the caption?
Yes. Creathoria's AI reads the video through the caption or the transcript of the speech, and reads carousels slide by slide. More details in how to transcribe Reels.
Does it work with TikTok and LinkedIn too?
Yes. Profile analysis works with Instagram, TikTok and LinkedIn (personal profile or company page). Instagram is on every plan, and TikTok and LinkedIn start with Creator. YouTube isn't analyzed.
Start with one profile and read the dossier before you paste any text
"Untitled document (3)" can stay in your folder, where it will probably never be opened again. In the dossier, the profile's hooks, structures and ranking are already separated, and you finish reading with a subject for your next post.
Pick the reference profile you study most and add its @ in Creathoria during the 14-day trial. Your card is registered and you're only charged at the end of the trial. Then open the dossier.
