AI Digest

The AI Digest is an automated pipeline that produces a daily newsletter summarizing AI developments, routed through an editorial approval workflow before publishing to the Musingly platform.

What It Does

  1. A Cloud Scheduler job triggers the pipeline daily at 8 AM UTC.
  2. A LangChain agent queries the Perplexity API for AI developments from the past 24 hours.
  3. The agent structures findings as JSON with titles, summaries, tags, and source links.
  4. A draft digest is sent to a Slack channel for editorial review.
  5. Reviewers approve or reject via interactive buttons.
  6. Approved digests are pushed to Payload CMS, which triggers a Next.js rebuild.

Audiences

The digest generates two summary variants per item:

  • Novice summary — Plain language explanation for readers new to AI.
  • Expert summary — Technical detail for practitioners.

Key Design Goals

  • Minimal manual effort per digest cycle.
  • Human approval required before any content publishes.
  • Cost-effective serverless execution — all components scale to zero.
  • Structured JSON output reduces hallucination risk through schema enforcement.

Further Reading

  • Architecture — System diagrams, component interactions, and data flow.
  • Specification — Implementation details, tech stack, cost model, and security design.
