Keyword-Based Email & WhatsApp Summaries

I want a small-footprint AI integration that watches every new email that lands in my inbox and each incoming WhatsApp message, immediately scans the content for two kinds of keywords—my product names/services and a few predefined phrases or topics—and then pushes a concise summary back to me on both channels.

The flow I imagine is straightforward:
• Trigger: new email or WhatsApp message
• Action: keyword detection + short, plain-language summary (no auto-reply needed at this stage)
• Delivery: the summary is sent to my email and appears in my WhatsApp chat so I never miss an important lead or topic.

Key points you should know
• Flexibility to expand or edit the keyword list without touching core code.
• Accuracy matters more than speed; a 30-60 sec turnaround is fine if it improves precision.
• I am not seeking full message categorisation or canned auto-responses right now, only the scan-and-summarise function.

Preferred stack
OpenAI (or similar LLM) for the summarisation, Gmail / Microsoft 365 APIs for email access, and WhatsApp Business API or Twilio for messaging. If you have a cleaner or more cost-effective approach, I am open to it.

Deliverables
1. Working code or low-code workflow that runs in production (Docker container, Cloud Function, or similar).
2. Simple dashboard or config file where I can add or edit keywords.
3. A brief deployment guide and demo showing one live email and one WhatsApp message being summarised and forwarded.

I’ll test by sending sample messages containing product names and watching for the combined summaries to arrive on both platforms. Once that works reliably, the project is done.
