ChatMimic
ChatMimic rewrites chat messages before they are sent, passing each one through the Gemini API under a profile the player configures.
What it does
Before a message reaches the server, ChatMimic can send its text to the Gemini API and replace it with the returned version. Each rewrite is driven by a profile, a named set of instructions the player writes to say how messages should change, so one profile might restyle text in the manner of a game and another might correct spelling. The Open Menu screen lists profiles, and a General Usage section covers the basics of sending a message through the mod.
The Gemini API needs a key from the player. Players paste their key into the key area in the mod's settings, where a SHOW API KEY control lets them reveal the stored key to check it. Without a key the mod has no service to call. The mod is published for Fabric only, for the single game version 26.1.2, with a 1.0.0 build dated 2026-07-04. It is client-side only, so only the client needs it and servers do not. ChatMimic is released under the Apache License 2.0, and it is not open source.

Use cases
Who it’s for: Players who want their chat messages transformed by the Gemini API and have a Gemini API key. Because the mod is client-side only, it suits single-player and multiplayer players alike, since servers need nothing installed.
How it compares
AskGemini is client-side only, open source under the GNU General Public License v3.0 only, and published for 1.21.11 on Fabric. URAI is client-side only, published for 1.21.11 on Fabric, and not open source, with its code under All rights reserved. ChatMimic differs from these by targeting 26.1.2 and running only on the client.
