AI dialogue, generated fresh for every moment. Now with real voiced delivery. Pick from 95 distinct voices, shaped by traits, mood, and relationship history.
Real output. Generated from the traits, moods, and relationship between two Sims.
Goofball + Affectionate · lovers · everyday banter
Romantic + Reflective · long-term couple · looking back
Hot-Headed + Neat · committed couple · the ongoing argument
Self-Assured + In Love · committed couple · the next step
No canned phrases. Every line is generated fresh from your Sims' state at that moment.
A personality engine that knows your Sims as well as you do.
Every line is generated from scratch using your Sims' current state. No canned phrases, no repeats.
Cheerful + Bookworm sounds nothing like Hot-Headed + Gloomy. Trait combinations shape texture, not just topic.
Mood and intensity bleed into every line. A Cheerful Sim having a bad day still finds the bright side, but they know it's a stretch.
Sims build history together. Shared milestones, old arguments, and inside jokes carry across play sessions.
Past moments surface naturally when relevant. "Remember when we met at the park?" And they actually do.
Want them to flirt, pick a fight, share gossip, or just say something specific? Type the topic and your Sim delivers it in their own voice.
95 distinct voices, each rendered with emotion-driven delivery cues the AI picks per line. Hear samples below.
Dialogue and notifications ship in 18 languages, matching whichever locale your game runs in. Voices speak the line as written, in language.
AI-generated dialogue, performed in 95 distinct voices. Same voice sounds different depending on the moment. Anger comes out clipped, intimacy whispered, surprise breathless. Not just text-to-speech: text-to-performance.
Real game clips · nothing scripted
Voice plays on player-directed chats. Background sim chatter stays text-only for now.
Confrontation · [clipped] meets [shaky]
Marcus Chen · Felix voice
“You knew for three weeks. Three weeks, and you said nothing.”
Iris Park · Hana voice
“Because I was scared. I was scared that telling you would end this, and I wasn't ready to lose you.”
Saying it out loud · [whispered] meets [breathless]
Diego Romero · Oliver voice
“Three years. I've held this in for three years. I love you.”
Vivienne Laurent · Luna voice
“You idiot. I knew. I knew the whole time. Come here.”
Each sim gets a voice the first time they speak. Don't like the pick? Reroll or browse the full pool in-game from a pie-menu.
Same voice, different mood, different sound. The model picks a delivery cue per line, so a flirty whisper and a furious snap come out of the same sim sounding nothing alike.
Voices speak in whichever language the line is generated in. Your French sims sound French; your Japanese sims sound Japanese. One voice, many languages.

Type anything you want your sim to say. The other sim hears it, reacts in character, and the conversation unfolds from there. Confront them, comfort them, flirt with them, interrogate them. Watch what they do.
It starts with one click
Click any sim. Pick “Tell them something…” from the Sims AI Chat menu.
You typed
“I read your diary. We need to talk about Brad.”
Liberty's reply
“Oh my god. You… you read my diary? Preston, that's private. That's really private.”
You typed
“I'm going to give you one chance to tell me the truth about you and Brad.”
Liberty's reply
“I… okay. I mean, there's not really much to tell. He was someone I was into before I came here, and then I got over it. That's it.”
Every response is generated fresh from her traits, mood, your shared history, and exactly what you just said. No canned lines, no branching trees. Try the same prompt twice; you'll get two different replies.
Every tier gets the AI dialogue, memory, and trait-driven personality. Higher tiers add bigger daily budgets and more voiced exchanges (Premium also gets early access to what's next).

The things people ask before they install. If yours isn't here, the contact form below goes straight to the dev.
Three kinds, all powered by the same AI:
Directed chat: you click any sim, pick "Tell them something…" from the Sims AI Chat pie menu, and type the line you want your sim to say. The other sim hears it and responds in character.
Player-clicked socials: the standard Sims 4 social interactions you already use ("Tell Funny Joke", "Flirt", "Discuss Career", etc.). The mod intercepts the result and generates AI dialogue based on the interaction type.
Autonomous chats: when your sims decide to socialize on their own. The mod generates dialogue for those too, so background chatter has substance instead of Simlish.
You have two caps and they count separately.
Conversation cap (e.g. 300/day on Premium) ticks up by one every time a dialogue is generated, whether it came from a directed chat, a player-clicked social, or an autonomous interaction. Anything that produces AI dialogue counts.
Voice cap ticks up only when a line is actually voiced. Right now that's only directed chats, so a Premium subscriber with 10 voice/day can voice 10 directed exchanges and still use the remaining 290 conversations for everything else.
Realistically no. Autonomous chats fire when sims decide to socialize on their own, not constantly, and not every interaction triggers one. In practice most players see a handful per Sim-day, not dozens. Your conversation cap is sized for a normal play session including all three types.
Voice budget is unaffected by autonomous chats since those stay text-only.
Voice is the expensive resource. By scoping it to lines you specifically typed, the budget covers the moments you actually care about: confrontations, confessions, and one-liners you set up yourself.
Player-clicked socials and autonomous chats still generate AI dialogue, just as text notifications. Voicing every social interaction would burn through any reasonable daily budget in minutes.
This is just the initial release. Voice is compute-intensive, so we're rolling it out gradually, and we plan to make it more widely available over time.
Yes. Click any sim, choose Sims AI Chat from the pie menu, then tap Turn voices OFF. Every directed chat now plays as text only, and your daily voice cap stops ticking. Flip it back the same way any time.
Yes. Click the sim, open "Voice options for <name>" from the Sims AI Chat pie menu. You can Reroll to cycle to the next unused voice in the matching gender pool, or Browse voices to open a picker with the full catalog and audition any voice before assigning.
Voice customization is available on any tier that has a voice budget (Free, Basic, Premium, Premium+ Voice).
Conversation cap: new dialogue stops generating until UTC midnight. Existing conversations stay readable; the mod just stops calling the AI until the budget resets.
Voice cap: voice silently switches off for the rest of the day. Directed chats still generate dialogue, just as text. Resets at UTC midnight.
Both reset at the same time. You'll see a one-time notification in-game when either cap is hit.
Generally yes. The mod hooks into the Sims 4 social interaction system the same way other dialogue mods do, and it coexists with WickedWhims, MCCC, Lumpinou's mods, and most others. If two mods touch the exact same interaction the standard load-order rules apply, but conflicts are rare in practice.
No. The mod doesn't modify your save file. It only generates dialogue overlays on top of normal gameplay. You can uninstall any time and the save loads cleanly without it; nothing in your sims, relationships, or world state depends on the mod being present.
Through Patreon directly. Your tier auto-syncs from there. Upgrade, downgrade, or cancel at any time and the mod reflects the change on next launch. No separate billing or account inside the mod.
