About this gig

Already have a workflow and want it to "read" text for you? I'll add an AI (LLM) step with the OpenAI or Gemini API to your existing n8n, Zapier or Make workflow, or to your Python script.


Common uses:

- Summarize emails, tickets or documents

- Classify messages (e.g. urgent / sales / support)

- Extract fields (name, date, order number) into JSON

- Draft standard replies for a human to review


What you get:

- The AI step added and connected to your workflow

- A tested prompt, checked against your sample inputs

- Short documentation: prompt, settings and how to adjust it


Experience: in my own project HeliOn I built a backend that orchestrates Gemini API calls, with prompt engineering to keep answers consistent. I'm also AWS Certified Cloud Practitioner.


How I work: we agree on the exact input and expected output first. You use your own API key, stored in your platform's credentials. API usage fees are paid by you directly to the provider.


I'm new on Fiverr, so I keep the scope small and clear. Please message me before ordering so I can confirm your platform and plan support the integration.
