Inline Variable Formatting Is Typebot's Most Underrated Feature

Fri, 24 Nov 2023 00:00:00 +0000

Most people use Typebot like a flow chart: one block per idea, variables set here, displayed there, a “Script” block whenever the logic gets spicy. That works — until your flow is forty blocks of scaffolding around three lines of actual logic.

The video covers the feature that changed how I build: inline variable formatting — JavaScript, evaluated directly inside any text block.

What it actually is

Anywhere you can type a variable in Typebot, you can also type an expression. That means you can:

Stop Paying the Middleman: OpenAI Vision Straight From Typebot

Sun, 19 Nov 2023 00:00:00 +0000

Every integration tutorial starts the same way: “connect this app to Zapier, Zapier to that API.” It works — until it doesn’t, and you’re debugging a chain of three services for a one-line API call. This video is the counter-argument: calling OpenAI’s Vision API directly from Typebot, no middleman at all.

What the build does

The flow: a user uploads an image in the chat, Typebot sends it straight to OpenAI’s Vision API (GPT-4V) via an HTTP request block, and the model’s description lands back in the conversation. Ask “what’s in this picture?” — get a real answer, all inside one tool.

Charging for Chat: The Stripe Pay-to-Chat Pattern

Wed, 18 Oct 2023 00:00:00 +0000

This is the most-viewed tutorial on the channel for a reason: it’s the one where the chatbot starts making money.

The pitch is simple — let users chat for free up to a limit, then pay to continue — and the video walks the high-level wiring using Typebot, Retune, and Stripe Checkout.

The pattern

Free questions first. The bot answers normally for the first few messages. This is the demo that sells itself — the visitor gets real value before being asked for a cent.
The gate. Hit the question limit and the flow pivots: here’s what you get, here’s the price, here’s a Stripe Checkout link.
Payment unlocks the session. After checkout, the flow continues into the paid experience — deeper answers, unlimited questions, whatever you promised.

No middleware servers, no custom auth stack. Typebot holds the conversation logic, Retune provides the AI, Stripe does what Stripe does.

Ask My Books: RAG With Retune's API Inside Typebot

Sat, 23 Sep 2023 00:00:00 +0000

At 2,600+ views, this is the most-watched video on the channel — and I think it’s because it answers the question everyone actually has: “Can I make a bot that knows my documents?” The answer is yes, in an afternoon, with no custom backend.

The build

Two moving parts:

Retune gets the brains. Upload the two books as data sources and it builds a searchable knowledge base — this is retrieval-augmented generation (RAG) without you writing any of the retrieval code.
Typebot gets the face. An API call block hits Retune’s endpoint, and the user’s question comes back as an answer grounded in the books.

That’s the whole architecture. The video shows the API call being configured end to end — endpoint, payload, and mapping the response back into the chat.
