Quick overview This workflow collects vendor proposal PDFs via an n8n Form, extracts text from the PDF, uses an OpenAI ChatGPT model to summarize and flag risks, logs the evaluation to Google Sheets, and sends an approval or review-needed notification through Gmail. How it works Receives a submission from an n8n Form with the submitter’s details, optional notes, and a vendor proposal PDF upload. Extracts text from the uploaded PDF and cleans/limits it to a safe length for AI evaluation. Sends the cleaned proposal text and submitter notes to an OpenAI ChatGPT model to return structured JSON with vendor details, summary, key points, and risks. Parses the AI response, formats key points and risks for readability, and flags the submission as “REVIEW NEEDED” when any risks are present. Appends the evaluation results to an “Evaluations” tab in Google Sheets with the decision, summary, and risk metadata. Sends a Gmail alert to the review team when risks are found, otherwise emails an auto-approval notification to the approver. Setup Add an OpenAI API credential and select the model for the OpenAI Chat Model used by the evaluator.

Monitor procurement spend and risks with Google Sheets, Groq Llama and Gmail
Quick Overview This workflow runs every 15 minutes to pull procurement transactions and department budgets from Google Sheets, calculate spend utilization and forecasts, generate executive risk insights with Groq Llama, write dashboard records back to Google Sheets, and email critical-risk alerts via Gmail. How it works Runs every 15 minutes on a schedule. Reads procurement transactions and department budget/threshold data from Google Sheets and combines them by department. Aggregates spend per department, calculates utilization, remaining budget, projected monthly spend, vendor counts, pending transactions, and assigns SAFE/WARNING/CRITICAL risk levels. Uses Groq (Llama 3.1) to generate an executive-friendly risk analysis and recommendations for each department based on the calculated metrics. Builds organization-wide dashboard totals (spend, projections, alert counts, highest-spend and top-risk departments) and attaches workflow metadata. Formats the results into executive summary, department insight, and risk alert records and appends them into separate Google Sheets tabs. Sends a Gmail escalation email when a CRITICAL risk alert record is detected. Setup Connect Google Sheets O
Run AI employee onboarding with Groq, Google Workspace, and Gemini
Quick overview This workflow ingests onboarding documents from Google Drive into an in-memory vector store with Google Gemini embeddings, then runs a multi-channel onboarding chatbot powered by Groq, sends role-based welcome emails via Gmail when a new hire appears in Google Sheets, and schedules day 1/7/30 check-in emails. How it works Manually runs an ingestion flow that lists files in a specified Google Drive folder, downloads them, extracts text, and indexes them into an in-memory vector store using Google Gemini embeddings. Receives employee questions via n8n Chat (and optionally Slack or Telegram), normalizes the message into a single format, and rejects empty or overly long inputs. Uses a Groq LLM agent with per-user session memory to retrieve relevant excerpts from the in-memory company_docs knowledge base and generate a grounded answer, or directs the user to HR when no relevant content is found. Routes the assistant’s response back to the originating channel (n8n Chat, and optionally Slack or Telegram). Triggers every minute on updates to a Google Sheets “Hires” sheet, validates rows marked as Hired, and skips hires already present in the “Tracking” sheet. Builds a depart
