A few months ago I started building n8n workflows with a focus on Instagram automation. I wanted to prove that with the right niche, consistency, and automation, real organic growth is achievable.
Workflows:
1.) Instagram Auto-Publisher from Google Sheets with DeepSeek AI captions
2.) Score Instagram Hashtag Engagement with Apify, Telegram, and Airtable
3.) Reply to Instagram Comments with Groq, Telegram Approval, and Google Sheets Logging
Three workflows, one niche, consistent execution. The stack is: Google Sheets as the content backbone, FFmpeg for video processing, AI for captions, Apify for hashtag research, Groq for comment drafting, Telegram as the human-in-the-loop interface, and Airtable + Google Sheets for logging and analytics.
Below you can read what the account looks like right now so you know this isn’t theoretical only:
- 2,836,978 views in the last 90 days
- 1,203,813 accounts reached
- 94.1% of views from non-followers — the algorithm is pushing this content cold
- 98.9% of all views from Reels
- 10,000 followers grown organically
- Top audience countries: USA (51.5%), UK (5%), Canada (4%), Germany (3.6%)
- Profile activity up +26.5% 30,413 profile visits, 298 external link taps
None of this involved any paid promotion, it’s faceless Instagram account, completly free, good niche and true power of n8n automation.
If you are in similar position and you think this can help, I am more then happy to discuss or answer questions!

Welcome @emel_rizvanovic! 2.8M views in 90 days is solid validation that the fundamentals are right. The combination of Google Sheets as a content calendar + DeepSeek for captions is clean - curious if you’re running into any rate limits with DeepSeek on high-volume days. One thing that could strengthen the reply workflow: add a short Wait node between Groq comment drafts before they go to Telegram approval, so you’re not reviewing 20 drafts at once after a post spikes.

Hey @nguyenthieutoan, thanks for checking out!
You’re absolutely right about the reply workflow suggestion.
Regarding DeepSeek rate limits: since I’m currently only posting every 24 hours, I haven’t hit any walls yet. However, I can definitely see the need for guardrails there as things scale up. Appreciate the feedback!

Really impressive work, and thanks for sharing real metrics instead of just describing the workflow. Seeing actual results, especially the reach, follower growth, and the percentage of non-follower views, makes the case much more compelling.
What I particularly like is that this isn’t simply “AI posting content.” You’ve built a complete automation pipeline with clear human oversight where it matters. Using Google Sheets as the content source, AI for content generation, Apify for research, Telegram for approvals, and Airtable for tracking creates a practical, production-oriented workflow rather than just a demo.
I’m curious about a few technical aspects:
- How do you prevent repetitive captions or content drift over time?
- Have you implemented any safeguards against Instagram rate limits or API restrictions?
- How do you decide when a Reel should be republished versus creating entirely new content?
- Which part of the workflow has had the biggest impact on growth: hashtag research, AI-generated captions, or posting consistency?

Hello @Merritt645 thanks for you checking and your awesome feedback!
I am happy that you like the automation pipeline with human oversights, since it was my first experience with n8n and posting content like that, I wanted still manual intervention so I can understand process better.
Regarding your technical ascpects:
- For my ninche I would rarely run on this issue because every reel would be unique with information and fun fuct but generally I would add checker before Chat Model for AI generation captions to see if we can reuse something and save tokens
- No safeguard
- It should go with Telegram
- The biggest impact on growth actually how and when do you post. If you post reels best strategy that works in my niche is post every 24h at same time, and every 7-8 reel will go “viral” or it will perform better then your previous reels. Hashtag research is great for inspiration and to see what is hot right now and AI comments replier is just created, need some time or eventually fresh new account.
Regards
