Gydr 2.0: the right AI model for every message

"What are your opening hours?" and "Which of these two plans suits a family of five with a dog?" are both one message long. They are not the same amount of work. A chatbot that sends both to the same model either overpays for the first or underperforms on the second.

Gydr 2.0 is built around that observation. It has two headline features. Dynamic Mode chooses the model for every message. Plugins let your chatbot reach the live systems your business already runs on.

Dynamic Mode: the right model for every message

You choose a set of models for a widget and turn on Dynamic Mode. From then on, your assistant routes each message to the model that fits it. Everyday questions stay fast and economical. Harder ones go to a stronger model. If a model cannot answer a question well, the conversation moves up to a more capable model from your set. If your knowledge base is written in another language, Dynamic Mode picks a model that can read it.

You see a clear cost indicator on every model, so you can build a set with confidence. Conversations in Dynamic Mode are billed at a discount.

We think this is where AI products are heading. The question used to be "which model should we use?" It is becoming "which model should answer this?" That decision belongs to each message, not to a settings page you visit once a year.

Plugins: beyond the knowledge base

A knowledge base is the right home for what your business knows: policies, products, opening hours. Some answers only exist in a live system, such as your order database, your booking API or the spreadsheet your team updates every morning.

Plugins connect your chatbot to them. Connect your own REST API with flexible authentication, custom headers and several endpoints. Or connect a Google Sheet, with an instruction for it and a mapping of its columns, so the assistant understands what the data means rather than just reading cells. A redesigned catalogue walks you through setup one tab at a time.

The first commerce connector is Shopify. The Shopify Storefront plugin lets your chatbot help shoppers search your products, check availability and hand off to your store's own checkout. One rule shaped its design: the assistant never places or pays for an order. Checkout always stays on Shopify, where the shopper is in control.

Remembering returning visitors

Visitor memory lets your chatbot remember helpful context about returning visitors, so a repeat customer does not have to start over. It is off by default. You switch it on per widget with a clear consent toggle, and you can review or erase what was remembered at any time from the visitor's profile.

Answers from your knowledge, not from the internet

This release also changes how the assistant decides what to say. It now answers strictly from your knowledge base rather than from what a model happened to learn in training. When the answer genuinely is not there, it says so instead of guessing. That principle has shaped almost every release since.

Testing got easier too. The "Try it out" sandbox is now open on every plan, including Free, so you can talk to your live chatbot before you publish it. Per-message and per-conversation credit costs appear in the Console, so usage is never a mystery.

Update, September 28, 2026. In Gydr 3.5 we switched off the Shopify tools that need a signed-in shopper, such as viewing a cart or looking up orders, because a chatbot cannot sign a shopper in. Product search and browsing were unaffected.

Frequently asked questions

What is Dynamic Mode?

A widget setting that sends each message to the best-fitting model from a set you choose, moves a conversation to a more capable model from that set when it needs one, and is billed at a discount.

What can Gydr plugins connect a chatbot to?

At launch: your own REST API, a Google Sheet and a Shopify storefront. Later releases added remote MCP servers and WooCommerce stores.

Is visitor memory on by default?

Not for guests: you switch it on per widget, with a consent toggle, and can review or erase what was remembered. Since Gydr 4.0 it is on automatically for signed-in visitors, unless you turned conversation history off.
