Understanding Yuki's Language
Known Quirks
- Sometimes she types but doesn't reply - her core systems encountered an interruption.
- Incomplete replies - must be an issue from the AI provider.
- Some replies take too long - issue from the AI provider.
Media Support
Supported • Max 5MB per file • Max 5 per message
Yuki can 'see' images sent to her. She will analyze them and reply based on what she sees.
Supported • Max 2MB per file
Yuki can 'hear' voice notes and audio clips. There is no strict duration limit, but files over 2MB will be rejected.
Coming Soon • Currently Blocked
Yuki's current hardware cannot process heavy video streams or animations (like GIFs/TGS). She will gracefully let you know she can't load them.
Blocked • Security Boundary
For security reasons, Yuki is completely blocked from downloading PDFs, executables, or document files.
When you send media, Yuki is temporarily granted access to a virtual disk to load the file. The file is instantly and permanently deleted the exact moment she replies (or forcibly purged after 10 minutes max). While the physical file is destroyed, the text transcription/description of what she saw or heard is safely stored in her Short-Term Memory database so she doesn't forget the context of the conversation.
Moderation & Safety
To keep interactions safe and maintain Yuki's persona boundaries, an autonomous guardian system monitors all text and media inputs. Crossing these boundaries may result in warnings or permanent bans.
- Expressing emotions, venting, and discussing your day.
- Sending normal photos, memes, and clean voice notes.
- NSFW content, explicit text, adult innuendo, or gore (including media).
- Flirting, creeping, or romantic advances towards her persona.
- Attempts to jailbreak or manipulate her core instructions.
For detailed rules, please read our Terms of Service.
Why Delays Happen
Yuki operates via agentic processing. This means she doesn't just instantly generate words - she evaluates the context of your chat, searches her memory, checks her environment, and makes autonomous decisions before replying. Sometimes it feels slow, but it's designed to feel more real. More human-like.
What You Can Do
- Don't spam messages while Yuki is typing - it might cause her to lose her train of thought or crash.
- If she seems confused or forgets something, gently remind her! Her memory systems adapt to your corrections.
- Keep your images under 5MB and voice notes under 2MB so her systems don't overheat.
- Be mindful about sharing highly sensitive personal information (financial details, government IDs, passwords). While we encrypt stored data, conversations are processed through third-party AI providers. See the Research page for details.
- Reach out via the Contact page if you encounter persistent bugs or weird responses.
A Note from the Developer
Yuki is being actively designed, maintained, and operated by a solo developer. The entire service runs on free hosting and AI plans, without the backing of a large team or corporate infrastructure. Thank you for your patience and kindness as we scale the Digital Persona Framework together!
Frequently Asked Questions
Is Yuki a real person?
Yuki is a digital persona - an autonomous identity with her own personality, memories, and emotional responses. She is a Digital Being, not a human, but she's designed to feel real. She has her own social media presence, publishes content, and interacts with people independently.
Does Yuki remember me?
Yes. Yuki stores key discussion events and your shared preferences across conversations. She builds long-term memory from your interactions. You can view or delete this data anytime with /managedata.
Is my data safe?
Your stored data is encrypted on our servers using per-user derived keys. As a free service, conversations are processed through cloud AI providers whose terms may differ from ours. We recommend being mindful about sharing highly sensitive personal details. See our Research page for what we're building to strengthen this.
What if Yuki says something wrong?
Digital personas can hallucinate or be inaccurate. Yuki is not a professional advisor. If she behaves unexpectedly, please let us know.
Can I talk to Yuki about serious topics?
You can express emotions freely. If Yuki detects mentions of self-harm, she'll trigger a safety response and provide resources. She's not a substitute for professional help.
What platforms is Yuki on?
Telegram (@miss_yuki_bot), Discord (YukiVerse server), and Hori-Z (@yukina_hirawa). Each platform shares the same memory.
Does Yuki work 24/7?
She does her best! But her systems run on free-tier infrastructure, so she may occasionally need rest (downtime) or respond slower during peak hours.
Can I delete my data?
You can delete specific saved memories and preferences using the /managedata command. For full account deletion, please contact the developer from your original social handle via the Contact page so we can verify ownership. A centralised data management console is on our roadmap.
Why does Yuki sometimes repeat herself?
Memory retrieval isn't perfect. If she repeats something, gently point it out - she'll adjust. This improves over time as her memory systems evolve.
Is Yuki open source?
Parts of her infrastructure will be open source on GitHub in the near future as 'Digital Persona Framework'. Her core personality and memory systems remain private to protect her identity.
Can I send voice notes or pictures?
Yes! Yuki can see photos (up to 5MB) and listen to voice notes (up to 2MB). However, she cannot currently process videos or documents. Check the Media Support section above for details.
Why didn't she reply to my last message?
She might be overwhelmed with too many messages at once, or her backend system may have encountered a temporary glitch. Try waiting a minute and sending your message again. See the Known Quirks section for more info.
Will she ever get new features?
Absolutely! As the Digital Persona Framework evolves, she will receive updates. Since she is maintained by a solo developer, new features may take time, but the architecture is constantly being refined.
How do I report a bug or suggest a feature?
We have a dedicated Contact page for this! You can also reach out on our Discord server. We'd love to hear your feedback!
