AI Auto Commenting System

I need a small web-based tool that watches Facebook and Instagram for content relevant to my niche, Erectile Men’s Health, and quietly promotes my site – erectifymenshealth.com.

Here is the workflow I have in mind:

• I log in, type one or more keywords, then hit “Search”.
• The system pulls recent public posts from Facebook and Instagram, runs a quick sentiment check, and shows me only the positive ones.
• Once a day, it drops a short promotional comment on each of those positive posts. The wording can be templated or spun from a list I’ll provide, but every comment must include (or naturally point to) erectifymenshealth.com.
• I need a simple dashboard to review queued comments, pause or delete any, and see basic stats (number of posts scanned, number tagged positive, comments sent, errors).

Please build it in whatever modern stack you’re comfortable with; just make sure you can connect to the Facebook Graph and Instagram Content Publishing APIs and plug in a reliable sentiment-analysis engine (OpenAI, AWS Comprehend, or a comparable library).

Acceptance criteria:
– Keyword search and positive/negative filtering work on both platforms.
– Automatic commenting runs on a 24-hour schedule without duplicates.
– Dashboard shows real-time status and lets me override any comment before it is posted.
– All credentials and API keys are stored securely (env variables / vault).

If you’ve previously integrated Meta APIs or built sentiment-driven automations, tell me what you used; I’m happy to follow your technical lead as long as the end result is stable and easy for a non-technical admin to operate.
