Instagram Comment Sentiment Analyzer 💬📊

Automatically scrape comments from any public Instagram post and get AI-powered sentiment analysis for each comment. Perfect for brand monitoring, influencer analysis, campaign performance tracking, and social listening.

What does it do?

This actor takes Instagram post URLs and:

1. Scrapes all comments (and optionally replies) from each post
2. Analyzes sentiment of every comment using NLP
3. Detects emotions (joy, anger, sadness, surprise, trust, etc.)
4. Understands social media slang — recognizes "fire 🔥", "slay", "mid", "cap" and 100+ Gen-Z/social media terms
5. Outputs structured JSON with scores, labels, and engagement metrics

No Instagram login required — works with public posts only.

• Competitor Research: Compare sentiment across competitor posts
• Crisis Detection: Spot negative sentiment spikes early
• Product Feedback: Extract customer opinions from product posts

Pricing

This actor uses pay-per-event pricing:

• $0.01 per comment analyzed
• Example: Analyzing 100 comments = $1.00
• You only pay for what you use — no monthly fees

Tips for Best Results

1. Use residential proxies for best success rates with Instagram
2. Start with smaller batches (50-100 comments) to test before scaling
3. Use enhanced engine for social media content — it understands slang and emojis
4. Filter by likes (minLikes) to focus on the most engaged comments
5. Monitor rate limits — the actor includes built-in delays to avoid Instagram blocks

Limitations

• Only works with public Instagram posts (no private accounts)
• Instagram may rate-limit requests — the actor handles this with automatic retries
• Very old posts may have limited comment availability
• Sentiment analysis works best for English; other languages have basic support

Support

Having issues? Check these common solutions:

1. No comments returned: Verify the post URL is correct and the account is public
2. Timeout errors: Reduce maxComments or try again later
3. Proxy errors: Use Apify residential proxies for best results
