My AI creates recurring Newsletter for any topic user is interested in

Overwhelmed by the constant flood of news?
SnapNews cuts through the noise, delivering only the most relevant, personalised information directly to user's email.

It's a combination of

• Google Search API
• GPT-4o mini API
• Perplexity API

User enters

• Topic of your interest (can be a prompt)
• Interval how often you want to receive summarised news

Steps my AI engine takes:

• GPT, understand Topic (prompt) and generate 3 search queries for Google API
• Google Search gets 10 results for each query within given Interval
• Google Search also gets "old news" for those queries to exclude them from summarisation
• GPT reviews all results, filters out old news, validates which results are relevant for given Topic
• GPT passes filtered links to Perplexity which opens them and creates Newsletter
• final Newsletter is sent to users email address

Tell me what do you think about this. Good, bad, potential improvements, anything that could help me improve it.
