Tsunderify
by ReMelon
Tsunderify edits chat messages on the client, turning swear words and plain phrasing into tsundere-style wording, with stutters and affirmations added at configurable rates.
What it does
Tsunderify is a client-side chat mod for Fabric. Its transformations run on incoming and outgoing messages in the local client only, so a player can use it on any server without the server needing a copy. Replacement rules cover swear words, which are swapped for tsundere-style phrases, and emphasis markers can be preserved so that a word stays stressed after the swap. The mod also changes how messages sound by adding stutter at the start of a line, and it appends affirmations at the end, each with a probability the player sets.
Commands are handled as well. Messages sent through Hypixel's party and guild chat shortcuts, and through vanilla commands such as whisper and message, pass through the same rules. Case is adapted to match the original text, so an all-caps line stays all caps after it is transformed. The mod is configurable through a settings screen built with YetAnotherConfigLib, and Mod Menu provides the entry point to that screen. Fabric API is required as well.
Tsunderify is released under the CC0 1.0 Universal license, which makes it open source, and its source code and issue tracker are public. Files exist for Fabric only, across 12 release versions, 1.21.4 – 26.2, with 1.4.0 as the latest build for 26.2, published on 2026-08-14. The mod was first published on 2026-01-10.
Key features
Swear word replacement
Profanity in chat is replaced with tsundere-style words, and the replacement list can be edited in the settings.
Stutter and affirmations
Messages can start with a stutter and end with an affirmation, each applied at a probability the player configures.
Emphasis preservation
Emphasized words keep their stress through the replacement, so a swapped phrase still reads as shouted or stressed.
Command and whisper support
Hypixel party and guild shortcuts and vanilla commands such as whisper and message are transformed like ordinary chat.
Case adaptation
Transformed text follows the capitalization of the original message, so all-caps lines stay in capitals.

How it compares
[BW] Better Whispers is open source under the CC0 1.0 Universal license, the same as Tsunderify, and targets 1.21.11 – 26.1.1 on Fabric, so it covers a narrower range of versions. DontJoinMyLobby is a Fabric client-side mod for 1.21 – 26.3 released under All rights reserved, so its code is not open source. SP_NTF_MSG is open source under the BSD 3-Clause License and is published only for 1.21.1.
