Multilingual AI Game Companion

An AI That Stays in Your Language — Portuguese, Spanish, Russian, Chinese, Arabic, and More

Most voice AI quietly slips back to English the moment you ask anything technical. You correct it once, twice, five times — eventually you give up and play in English. Sidekick AI locks the conversation language for the whole session and the next one. Tell it to speak Portuguese and it speaks Portuguese, even when you ask about an Elden Ring boss or a Minecraft redstone build.

How It Works

Language Lock That Actually Sticks

When you set the language, Sidekick AI uses it as a hard constraint — not a hint the model is free to ignore. The avatar replies in your language whether you're asking about gameplay, a build guide, or just venting about your day. The setting persists across sessions so you don't have to re-tell it every time you launch.

Voice That Speaks Like a Native

Each supported language has dedicated voices designed for that locale — not a generic English voice with an accent. Portuguese sounds Brazilian. Spanish has Latin American and Castilian options. Mandarin uses native intonation. The voice you hear matches the way the language is actually spoken.

Game-Aware in Every Language

Vision AI sees your game; the response comes back in your language. Boss names, item names, and quest names are kept in the original game language (most games ship menus in English) so you can still cross-reference a wiki — but the explanation around them is fully localized.

Switch Languages Mid-Session if You Need To

Streaming with friends from different countries? Tell Sidekick to switch — the language changes without losing context. Push-to-talk in another language for a single message and snap back. The session memory stays consistent across the switch.

Game Guides Available in Multiple Languages

Sidekick speaks the language of the game and your language — game terms stay in their original form, explanations come back localized.

Frequently Asked Questions

What languages does Sidekick AI support?
Sidekick AI ships with first-class support for English, Portuguese (Brazilian), Spanish, Russian, Mandarin Chinese, Arabic, Italian, Japanese, Korean, French, and German. Roughly 15% of all Sidekick conversations today happen in non-English languages — Portuguese and Russian lead, with Chinese, Spanish, Arabic, and Italian close behind.
Does the AI actually stay in my language across sessions?
Yes. Most voice AI assistants treat language as a soft preference — they listen to whatever you say, then default back to whatever they were trained primarily on (usually English). Sidekick AI passes the chosen language as a locked variable to the model on every turn, including across session restarts. The avatar will keep speaking Portuguese (or whichever language you set) until you explicitly change it.
Why do other AI assistants keep reverting to English?
Two reasons. First, most general-purpose voice AI is optimized on English-heavy training data, so the model gravitates back to English under uncertainty (a technical question, an unfamiliar game, a code-switch in your input). Second, most assistants don't expose a hard language constraint — language is a vibe, not a setting. Sidekick AI uses an explicit language parameter passed on every conversation turn, so the model can't drift.
Can I switch languages mid-conversation?
Yes. Open the language picker and Sidekick switches on the next response — the avatar finishes the current sentence, then continues in the new language. Conversation memory is preserved across the switch, so you can ask follow-up questions in the new language without re-explaining context.
Does language locking work for voice or just text?
Both. The voice you hear, the words on screen, and the avatar's spoken response all respect the locked language. Text-to-speech voices are language-specific (no Portuguese-with-American-accent mismatches), and Sidekick uses native-locale voice models for the supported languages.
Which languages have the best support today?
English, Portuguese, Spanish, and Russian are the most polished — they have the highest conversation volume, the most refined voice options, and the most thoroughly tested game-context handling. Mandarin, Arabic, Italian, Japanese, Korean, French, and German are fully supported but see lower daily usage, so edge-case quality may vary by topic. We track per-language quality metrics and ship updates when a language falls below the bar.
Is multilingual support included in the free tier?
The free demo lets you test any supported language. Persistent language locking — where your preference sticks across every session, every restart, every game — is a Pro/Ultra plan feature. The reason: language-locked sessions use slightly more context per turn, and we want to make that sustainable for the people who actually rely on it.
When is Sidekick AI available?
Sidekick AI launches on Steam in 2026. Wishlist now to get early access. The free Steam demo lets you test that your native language works the way you expect before launch.
