Question 1

What is Momory?

Accepted Answer

Momory is a real-time translation AI partner for live streamers. It uses Google's Gemini API to provide high-quality multilingual subtitles with a Zero-Server Storage philosophy, ensuring your data and API keys stay primarily in your browser.

Question 2

What is the technical philosophy of Momory?

Accepted Answer

We focus on three pillars: Absolute Privacy (Zero-Server Storage), Multi-Platform Accessibility (Browser-based), and Secure & Stable Integration. Despite being a web app, we choose technologies like OBS WebSocket over 'Browser Sources' to avoid the need for server-side data storage, ensuring professional-grade stability while keeping your data strictly in your control.

Question 3

Who is the developer of Momory?

Accepted Answer

Momory is a passion project created and maintained solely by matsumotory. As a personal development project, it's built from the perspective of an active developer and user who loves technology and streaming.

Question 4

What are the benefits of it being a personal project?

Accepted Answer

Speed and freedom! Decisions depend entirely on matsumotory, allowing for rapid experimentation and implementation of interesting features suggested by users without the overhead of corporate bureaucracy.

Question 5

What is the license of Momory?

Accepted Answer

Momory is released under the MIT License. We believe in the spirit of open source and want to contribute back to the developer and streaming communities.

Question 6

Accepted Answer

We deeply appreciate your interest in supporting us! You can contribute through the Support page linked in the sidebar. Your support directly helps with server costs, AI infrastructure, and the continuous development of new features.

Question 7

How can I check for the latest updates?

Accepted Answer

Momory is constantly evolving! You can find a detailed history of improvements, bug fixes, and new features on the Updates page in the sidebar. We recommend checking it regularly to get the most out of Momory.

Question 8

Are there copyright concerns with translating movies or videos?

Accepted Answer

It is your responsibility as the user to ensure you have the rights to stream or translate the content. Momory is a tool and is not responsible for the content you choose to process. Please respect copyright laws and the terms of service of the platforms you use.

Question 9

Which browsers are supported?

Accepted Answer

We officially support and highly recommend the latest version of Google Chrome. The 'Media Audio Mode' relies on advanced APIs (getDisplayMedia with SODA integration) that are most stable in Chrome.

Question 10

Media/VC Mode isn't working or shows an error.

Accepted Answer

This is often due to the browser's on-device speech recognition engine not loading correctly. The most reliable solution is to completely close and restart Chrome (you can use `chrome://restart`). Also, ensure you have the necessary language pack installed for 'Live Caption' in Chrome's accessibility settings.

Question 11

How do I get started?

Accepted Answer

1. Obtain a Gemini API key from Google AI Studio.
2. Enter the key in the Momory Dashboard settings.
3. Select your input mode (Mic, Media, or VC) and configure languages.
4. Turn on the microphone/capture button in the dashboard to start translation.
5. Set up the OBS WebSocket Integration (Recommended) to send subtitles to your stream.

Question 12

How does the AI 'learn' my style?

Accepted Answer

Simply talk to it! When the AI provides a translation you like, say "Nice translation!" or "Good translation!". The AI detects this voice feedback as a signal to prioritize that style, context, and tone in future sessions. You can also provide custom instructions in the AI Prompt section.

Question 13

How do I set it up in OBS?

Accepted Answer

We recommend the OBS WebSocket Integration for the best experience. For detailed steps, see our OBS Setup Guide. You can also use the traditional Window Capture method with the Chroma Key filter.

Question 14

Can I use Momory for commercial streams?

Accepted Answer

Absolutely! Momory is designed to support creators, and you are free to use it for both non-commercial and commercial streams. We want to help you reach a global audience, regardless of your channel's scale or status.

Question 15

What are the future plans for Momory?

Accepted Answer

Future plans include further improvements to the core transcription and translation accuracy, simplifying OBS setup, and boosting performance with paid-tier APIs.

Question 16

What is 'Adaptive Debounce' and how does it work?

Accepted Answer

It's a smart algorithm that balances speed and accuracy. In Burst Mode, it responds in 1.2s when you start talking after a silence. In Flow Mode, it waits up to 2.0s during continuous speech to gather more context, ensuring higher translation quality. Learn more in our Tech Insights.

Question 17

How is my data handled? Is it safe?

Accepted Answer

Momory has a Zero-Server Storage policy (we don't store data). However, Google processes your data in two independent steps: 1) Web Speech API (Transcription): Audio is sent to Google and may be used to improve their service regardless of your API key. 2) Gemini API (Translation): Text is processed here. If using Free Tier, data may be trained on. Paid Tier ensures NO training for the translation part.

Question 18

Does Gemini API cost money? What is the best setup for price/performance?

Accepted Answer

Google provides a Free Tier. For professional streaming, we recommend the Paid API key with 'Smart (2.5 Flash Lite)'. In tests, 3 hours of streaming cost only ~$0.06. This ensures your translation data is NOT used for AI training.

Question 19

The overlay display in OBS is unstable or stops updating. How can I fix this?

Accepted Answer

We highly recommend switching to the OBS WebSocket method, which is significantly more stable. If using the overlay window, ensure it is slightly visible on your screen and not minimized.

Question 20

The dashboard preview isn't updating, but the overlay works. Why?

Accepted Answer

This is an intentional power-saving feature. When the dashboard is not visible, UI updates are paused to prioritize system resources for your game. Background processing and data delivery to the overlay continue normally.

Question 21

I found a bug or have a feature request.

Accepted Answer

We value your feedback! Please reach out via DM/reply to the developer's X (Twitter) or leave a comment during their live streams. Your voice directly shapes the future of Momory.

Question 22

What technology is it built with?

Accepted Answer

Momory is built with Next.js (App Router), TypeScript, and Tailwind CSS. Read our Tech Insights for a deep dive into our architecture and AI implementation.
