1.1 Workflow description

Title: Process Voice Notes to AI Responses with Claude Sonnet, Nuclino & Slack
Workflow name: Process Voice Notes to AI Responses with Claude Sonnet, Nuclino & Slack

This workflow provides a way to capture detailed AI prompts using a voice note transcription service and then passes them on for completion to an AI agent.

To preserve outputs in a knowledge management system, the AI response and the prompt are combined into one document that is created in a Nuclino collection (note: the Nuclino step is configured manually with a HTTP request node).

How it works

A webhook receives voice note data from Voicenotes.com containing the title and transcript
The transcript is extracted and sent to an AI Agent powered by OpenRouter's Claude Sonnet model
The AI generates a structured response in markdown format with Summary, Prompt, and Response sections
The original prompt and AI response are merged and prepared for multiple outputs
A Nuclino document is created via HTTP Request with the structured content
A Slack notification is sent with the prompt, response, and Nuclino note URL
Both the original prompt and AI response are archived in NocoDB for future reference

How to use

The webhook trigger can be configured to receive data from Voicenotes.com or any service that provides title and transcript data
Replace the manual trigger with webhook, form, or other triggers as needed
Customize the AI system message to change response format and behavior
Configure Nuclino workspace and collection IDs for proper document organization

Requirements

OpenRouter account for AI model access (Claude Sonnet)
Nuclino account and API token for document creation
Slack workspace with bot permissions for notifications
NocoDB instance for archiving (optional)
Voicenotes.com account for voice input (or alternative webhook source)

Customising this workflow

AI Models: Switch between different OpenRouter models by changing the model parameter
Response Format: Modify the AI Agent system message to change output structure
Documentation Platforms: Replace Nuclino HTTP Request with other documentation APIs
Notification Channels: Add multiple Slack channels or other notification services
Archive Storage: Replace NocoDB with other database solutions
Input Sources: Adapt webhook to accept data from different voice note or transcription services

Nuclino API

The Nuclino API is documented here.

Build a RAG knowledge base from PDFs with Gemini, Supabase and Google Sheets

## Quick Overview This workflow ingests educational PDF URLs from Google Sheets, extracts and chunks their text, generates embeddings with Google Gemini, and stores them in a Supabase pgvector table for retrieval, while also exposing a public chat webhook that answers questions using Gemini and the same Supabase knowledge base. ## How it works 1. Runs every hour on a schedule and reads rows from a Google Sheets document, keeping only entries where the status is empty. 2. Processes each queued URL one at a time and routes it based on whether it is a seraj-uae.com page or a direct Google Drive file link. 3. For seraj-uae.com URLs, fetches the HTML page to extract the PDF download link (or embedded Google Drive file ID) and the document title. 4. Downloads the PDF from either the source website via HTTP or from Google Drive, waits briefly, and extracts text from the PDF binary. 5. Cleans and validates the extracted text, then splits it into overlapping chunks and generates embeddings using Google Gemini. 6. Inserts the embedded chunks into a Supabase pgvector table with file/title/source metadata and updates the Google Sheets row to “Embedded” or “Not Text Based PDF” if no text is found. 7. Separately, exposes a public n8n Chat webhook that receives student questions and uses Gemini Flash with Supabase vector retrieval to return answers. ## Setup 1. Create a Supabase project with pgvector enabled, create the seraj_documents table, and add the match_seraj_documents function used for vector search. 2. Add Supabase API credentials in n8n and ensure the table name (seraj_documents) and query function name (match_seraj_documents) match your Supabase setup. 3. Add Google Sheets OAuth2 credentials and update the Google Sheet document ID/sheet reference, ensuring columns include source_url, status, and row_number. 4. Add Google Drive OAuth2 credentials for downloading PDFs hosted in Drive. 5. Add a Google Gemini (PaLM) API credential for embeddings and Gemini Flash, then activate the workflow and copy the public chat webhook URL for your website chat widget.

Build a Slack knowledge graph with Claude, Neo4j and Google Sheets

## Quick Overview This workflow ingests chat messages via a webhook or a 15-minute schedule, filters out low-signal content, uses Anthropic Claude to extract entities and relationships, and stores the resulting knowledge graph in Neo4j while appending an audit log row to Google Sheets. ## How it works 1. Receives a chat message via an n8n webhook or runs every 15 minutes to process polled Slack data. 2. Normalizes the incoming payload into consistent fields like channel, sender, timestamp, and message text. 3. Uses a Python script to tag message signals (questions, decisions, action items) and filter out noise such as greetings, bots, and very short messages. 4. Sends each relevant message to Anthropic Claude to extract entities, relationships, a summary, message type, and importance. 5. Sends the extracted graph to Anthropic Claude again to add implicit relationships, weights, decision-chain metadata, and a thread category. 6. Merges both AI passes into a single nodes-and-edges knowledge graph, validates references and edge weights, and drops invalid graphs. 7. Upserts the graph into Neo4j via its transactional HTTP endpoint, appends an audit row to Google Sheets, and returns a JSON success response to the webhook caller. ## Setup 1. Add an Anthropic API credential and select the Claude model used by the two AI steps. 2. Configure Neo4j access by replacing the Neo4j HTTP endpoint URL and setting up HTTP Basic Auth credentials for your Neo4j instance. 3. Configure Google Sheets OAuth2 credentials and replace the placeholder Google Sheet ID, sheet tab name/range (KnowledgeGraph), and any required API permissions. 4. If using the webhook ingest path, copy the production webhook URL from n8n and configure your Slack/app integration to POST message payloads to `/chat-ingest` with the expected fields (text, channel, sender, timestamps).

Answer voice queries from a webhook over Google Drive docs using GPT-4o-mini and Supabase

## Quick overview Placetel AI – RAG Voice Assistant with Google Drive & Supabase ## How it works 1. Runs on a daily schedule at 02:00 or via manual start to reindex documents. 2. Lists files from a specified Google Drive folder and iterates through each file. 3. Downloads each Google Drive file, loads its text content, creates embeddings with OpenAI, and stores the resulting chunks in a Supabase vector table. 4. Receives a question via a POST webhook with a JSON body containing `chatInput`. 5. Generates an answer with GPT-4o-mini by semantically retrieving relevant passages from the Supabase vector store using the same OpenAI embeddings model. 6. Returns the generated, source-cited response to the webhook caller for voice output. ## Setup 1. Add Google Drive OAuth2 credentials and replace `DEINE_ORDNER_ID` in the Drive query with the folder you want to index. 2. Add an OpenAI API credential and ensure the same embeddings model/settings are used for both indexing and querying. 3. Create/configure a Supabase project with a `documents` table and the `match_documents` RPC/query used for vector search, then add your Supabase credentials. 4. Copy the webhook URL from the webhook trigger and configure your calling system to POST `{ "chatInput": "..." }` to it.
