Welcome to the UNITH Docs

Improved response speed - We've significantly improved response speed for longer responses. No action is needed on your end — you should automatically see better performance, particularly for longer digital human responses. This improvement applies across all TTS providers we currently support.

Widget auto-open - If you're using widget mode, you can now configure the widget to open automatically, with control over the delay before it opens. This is set via a simple additional parameter. See full documentation here.

Widget focus fix - We've resolved a previously known issue where the embedded widget could conflict with focus behaviour on the parent page. Along with this, several other widget stability fixes have been shipped.

Contact modal Update - The contact modal in interFace has been redesigned, making it easier for potential clients to get in touch with UNITH.

New languages support - We've added support for three new languages: Turkish, Swedish, and Finnish. If you need a language that isn't yet supported, please get in touch with us.

Improved digital human session behaviour Inactivity and timeout handling during digital human interactions has been significantly improved. Both states are now properly coordinated so they no longer conflict with active sessions. As a result, you will no longer see prompts asking whether you are still present while the digital human is in the middle of responding. We have also enhanced greatly the behaviour of established websocket connection.

Change the visual appearance of an existing digital human You can now reassign the head visual of a digital human after it has been created. To do this via the interface, open the digital human, click Edit, then hover over the avatar image to access the change option. To reassign a head visual via API, refer to the "Create Head Visual" documentation.

Clearer prompt guidance in the interface Warning messages across the interface have been updated to provide more actionable guidance when building digital human prompts.

API key required when setting a custom LLM When configuring a custom language model, you are now required to provide your own API key. This ensures that custom LLM integrations are properly authenticated from the start.



IN-PRODUCT RELEASE NOTES

We want to make sure you're always aware of what's new. After each deployment, you'll be able to see a summary of newly released features directly from the interFace.

HEAD VISUAL ORGANISATION

We're continuing to grow the avatar catalogue steadily, and with more visuals comes the need for better organisation. We're improving how head visuals are structured and browsed in the interFace so the expanded catalogue stays manageable and easy to navigate. To learn more, check out our head visual documentation.

VOICE INTERRUPTION

You can already stop a digital human's response with the stop button. We're now adding the ability to interrupt via voice — so you can cut in naturally, mid-response, without reaching for a button. This will be configurable per individual head ID, giving you fine-grained control over where and how interruption is enabled. To learn more, please check this link.

CUSTOM DATA TAGS

You can now label each digital human deployment with a custom tag. That tag travels through the entire system and appears in your usage logs, so you can finally tell apart which website, campaign, or platform is driving which activity.

This gives integrators a clean, low-friction way to segment usage by deployment, campaign, platform, or whatever distinction is relevant to your setup. Please see full details here.

We expect to deploy these changes to production as early as February 27, 2025.

We are excited to announce a soft reskin of our current digital human user-facing frontend, enhancing the look and feel while maintaining its core functionality. Below is a list of changes that will be implemented starting December 10th.

These updates are designed to improve user interaction and overall aesthetics. To assist our integrators in preparing for these changes, we are providing bundles (css and javascript) that allow you to test the new interface locally. This ensures that your implementation remains seamless and fully functional.

Please review the changes below and utilize the provided bundles to confirm everything aligns with your current setup.

To facilitate the process, the following code snippet, incorporating the required modifications, is provided for your testing purposes prior to the live deployment.
