Description

Give your team a chat that returns clear answers with real sources. An OpenAI assistant looks up your files and shows citations, and n8n formats the reply for easy publishing. Great for help desks, internal wikis, and content teams that need trusted responses.

A chat button in n8n starts the session and sends the prompt to an OpenAI assistant that uses a vector store. After the reply, the workflow calls the OpenAI API to fetch the full thread so every citation is captured. Split steps break messages, content blocks, and annotations into parts. Another call grabs file names from each file id. A Set and Aggregate step shape a clean list of citations. A Code step replaces citation markers with Markdown links, and you can turn Markdown into HTML at the end. A memory buffer keeps recent chat context so answers stay on topic.

You only need an OpenAI API key and an assistant set up with file retrieval. Expect faster review and fewer manual edits because sources are linked for you. Use it for support answers, internal knowledge articles, and sales enablement notes where proof and clarity matter.

  • Code step replaces markers with Markdown links to sources
  • Optional Markdown to HTML output for websites or help centers

What are the benefits?

  • Reduce manual source checking from 30 minutes to 3 minutes per answer
  • Automate 90% of formatting work for cited replies
  • Improve trust by showing sources in every response

How to set this up?

  1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
  2. You'll need accounts with OpenAI. See the Tools Required section above for links to create accounts with these services.
  3. In your OpenAI account, go to the API keys page and create a new secret key. Copy it to a safe place.
  4. In the n8n credentials manager, create a new OpenAI credential using API Key. Name it clearly, for example OpenAI Prod, and paste your key.
  5. Open the OpenAI Assistant node and select your OpenAI credential. Enter the assistant ID from your OpenAI dashboard. Make sure the assistant has file retrieval and a vector store with your files.
  6. Open the Get ALL Thread Content node. Confirm the OpenAI credential is selected and the header OpenAI-Beta assistants=v2 is present.
  7. Open the Retrieve file name from a file ID node and choose the same OpenAI credential. Keep the default settings.
  8. Review the Code node. Adjust the link format or text replacements to match your site or knowledge base style.
  9. If you need HTML output, enable or keep the Markdown to HTML node active. If you prefer Markdown, disable that node.
  10. Activate the workflow. Click the chat button in n8n, ask a question that should use your files, and wait for the final message with linked citations.
  11. Check the output. If no sources appear, confirm your assistant uses retrieval, your files are processed, and the thread messages include annotations.
  12. If you see API errors, check your OpenAI key, rate limits, and that the assistants v2 header is set on the HTTP nodes.

Automate Redis OpenAI Chat Consolidation
Turn busy chat streams into clear, single messages ready for fast replies. Useful for support teams and any chat based queue that needs fewer prompts and lower costs. Great for websites, help desks, and messaging inboxes that receive many short messages in a row. Incoming chat text is buffered in Redis with a context id. The flow tracks last seen time, counts new messages, and sets a waiting flag so only one batch runs at a time. A smart wait time is calculated from word count, then an inactivity or count check decides when to consolidate. When ready, all buffered messages are pulled, reversed for order, and sent to an information extractor that removes duplicates and returns one clean paragraph using an OpenAI chat model. After reply, the buffer, counter, and waiting flag are cleared. You need Redis and an OpenAI API key. Map your context id so messages from the same user stay grouped. Expect fewer API calls, faster answers, and better agent focus. Good for live chat triage, WhatsApp style threads, and internal help queues. Adjust the wait rules to fit your volume and message length.

Connect OpenAI Weather Chat Support
Run a hosted chat that gives instant weather answers for any city. An AI agent guides the conversation, asks for the city if needed, and returns a clear multi day forecast. This fits travel teams, event planners, and customer portals that need quick updates. Messages enter through a web chat trigger. A short term memory node keeps context so follow up questions make sense. The agent uses OpenAI to decide which tool to call and in what order. It first turns a city name into latitude and longitude using the Open Meteo geocoding API. Then it pulls daily max temperature and rain totals from the Open Meteo forecast API with the requested number of days. The reply goes back to the same chat in one flow. You only need an OpenAI API key. The weather API is public and needs no key. Expect faster replies, fewer mistakes, and less manual lookup work. Common uses include trip quotes, field team scheduling, and outdoor event planning. After activating, test with a message like Weather Forecast for the Next 7 Days in São Paulo.

Launch OpenAI Chat Customer Support
Give your website or helpdesk a smart chat agent that remembers the conversation. It can greet someone, remember their name, and answer follow up questions in the same session. Ideal for customer support teams that want fast and consistent answers without adding more staff. Here is how it works. A public chat trigger captures each message. A simple memory block keeps the last 20 messages per session using a session ID. The OpenAI Assistant creates the reply using the live chat input and the stored context. A built in calculator tool helps the bot handle numbers and quick math. The result is a chat that understands context, handles follow ups, and gives clear answers in one place. You only need an OpenAI account and an Assistant ID. Add your OpenAI API key in n8n, set the Assistant ID in the node, and keep the memory settings as provided. Expect faster replies on common questions and fewer repeated details from users. Good fits include FAQ support, pricing and quote checks with math, and internal help for simple IT or HR questions.
