WELCOME TO THE BETA
We at Razer are excited to announce the launch of Razer Synapse 4 Open Beta, providing users with ongoing access to the next evolution of Razer’s device configuration software.
Available as an optional download, we invite you to help shape Synapse – starting with the debut of Workshop, a powerful new customization hub built into Synapse 4 Open Beta.
We look forward to your direct feedback here at Razer Insider.
INTRODUCING: WORKSHOP
Workshop is a new community-driven platform built into Synapse 4 Open Beta, designed to make it easy for users to share and apply custom profiles.
Whether it is a finely tuned DPI setting, a complex macro layout, or a full Razer Chroma™ RGB setup, Workshop will enable users to explore and adopt configurations from fellow gamers worldwide without relying on third-party links or file transfers.
PHASED MACROS
Do more with a single key by having different actions based on its state: on press, while held, and on release.
AI PROMPT MASTER FOR ALL
Razer’s AI Prompt Master offers immediate access to the third-party AI services, streamlining and speeding up the prompt creation process. Quickly rephrase, summarize, and craft a personalized prompt with minimal disruption to your workflow.
Initially released to devices such as the Razer Pro Click V2 and the Razer Basilisk Mobile, AI Prompt Master is now available for a wider selection of devices.
