Workflows that use OpenAI API.
6 workflows
An AI engineer describes a retrieval-augmented chatbot deployed for one client with over 500 PDFs, with the chunking and retrieval choices, and reports 94% answer accuracy against 61% for plain GPT-4.
A deliberate experiment built a 60,000-page site with a small OpenAI model for about $10 and recorded that AI crawlers requested it far more than Googlebot. The author expects it to be deindexed.
A solo SaaS builder describes a Stripe-connected MRR and churn dashboard that sends metrics to GPT-4 for plain-language suggestions, and the blog and calculators used to drive early traffic.
A builder documents a 21-node n8n workflow that scrapes freelance developer leads, validates emails, looks up a GitHub bio, writes a personalised email with GPT-4o-mini and sends it with pauses between messages.
A hosting company's tutorial builds an n8n flow where a form webhook enriches each lead, has OpenAI score it, saves it to Airtable and posts the score to Slack.
A developer used ChatGPT for ideation, code and copy to ship a $9 content-repurposing tool in a weekend, and reports a handful of paying users and a messy build.
