Switch nodes + Redis nodes are underrated when building chatbots.
In my opinion, these two are some of the most useful nodes for building solid chatbot logic in n8n.
🔀 Switch nodes → help route conversations based on intent, conditions, user type, or previous messages.
⚡ Redis nodes → help maintain conversation state, store temporary data, and give the bot memory across messages.
Together, they make it much easier to build chatbots that go beyond simple “if this, then that” workflows.
What do you think?
Which n8n node do you find most useful when building chatbot logic? 👇
@Ibrahim Zia Switch for intent routing and Redis for conversation state is a practical pairing. I also lean on Merge nodes when parallel lookups need to rejoin before the bot replies.
Good picks. One Redis detail worth getting right early: always set a TTL on the session keys — otherwise every conversation you've ever had stays in memory forever, context can leak between sessions, and memory costs creep up. Keying session state by chat ID with a rolling TTL...
Absolutely! 👏 TTL is one of those small details that makes a big difference in production. A rolling TTL with the chat ID as the session key is a great way to keep conversations isolated while preventing Redis from filling up with stale session data. Thanks for the insight!

Automating Resume Screening with AI
I recently worked on a recruiting bot that uses n8n to connect Gmail, Groq AI, and Google Sheets. The goal was to automate the resume screening process and save time for the HR team. I'm happy to say that it's working smoothly and has already saved a significant amount of time. The tech stack was a bit challenging to set up, but it was worth it in the end.

Built this interactive APK platform concept with ChatGPT + custom HTML, CSS & JavaScript.
The idea was to take the typical APK website and give it a more polished, Framer/Webflow-style product experience.
I created the layout, visual direction and interactions, then used ChatGPT to help develop the custom code and refine the experience.
✨ Custom-built interactions
📱 Interactive phone UI
🖱️ Mouse parallax effects
