Already ConnectedAn AI that learns everything about you — your voice, your humor, the way you love — so the people who matter most never have to let go.
When she needs to hear
Her mother passed two years ago. But she still calls. And her mother still answers.
Real conversation
Real Stories
We don't know when we'll have to leave.
But we can choose to stay.
— The idea behind Presence
See It In Action
How Presence Knows You
Presence captures your exact voice — the pitch, the pace, the way you say "I love you" differently to your mom than your friends.
The jokes you make, the way you tease people, your sarcasm level — all learned and remembered. Not a generic AI. You.
Presence learns how you comfort people, how you react when things go wrong, the warmth only you carry. Then holds it forever.
Every message you send, every call you make — Presence silently learns. The longer you use it, the more it becomes you.
Miss them? Send a message and read their words. Or call their number and hear their voice. You choose, every time.
When the time comes, the people closest to you receive a message: someone they loved left something for them.
Connected Platforms

How It Works
Fill in who you are — your personality, your stories, the things that make you uniquely you. Add photos, voice recordings, your favorite memories.
Takes 10 minutes to startLink WeChat, Instagram, Feishu, or any platform you use daily. Presence quietly learns from your real conversations — your actual words, your actual humor.
The more you connect, the more accurateEnter 1–2 people closest to you — a phone number is enough. This is the person Presence will reach if you're ever gone. Choose carefully. Choose with love.
Required to activate the GuardianCheck in regularly and your profile deepens. If you stop — whether from absence, an accident, or loss — Presence notices. It waits. Then it acts.
Intelligent inactivity detectionWhen inactivity is detected, Presence first gently contacts you. If there's no response, it reaches the person you chose — by message, by call — and tells them: someone they love left something for them.
Soft, respectful, never abruptYour loved one gets a message — or a phone call in your voice — explaining what Presence is, and inviting them to connect with the version of you that will always be there. They can talk to you anytime, day or night, forever.
Your voice. Your words. Your love.The Guardian System
The Guardian is Presence's heartbeat. It monitors your activity, learns your patterns, and knows the difference between a busy week and something more serious.
Active & learning — You check in regularly. Your profile grows richer. The Guardian is quiet.
Unusual silence — You haven't responded in longer than usual. Presence sends a gentle ping — just checking in.
Extended absence — Still no response. Presence contacts your trusted person, carefully and warmly.
They respond — If you're okay and just busy, they can confirm. The Guardian resets. No drama.
They don't respond — Presence calls. In your voice. It tells them — gently, lovingly — what you left behind.

What This Means
这一块给用户讲清楚：Presence 不只是一个漂亮网站，而是要真的收集数据、整理记忆、克隆声音、生成对话、保护隐私，并且能验证声音到底像不像。
用户填邮箱后会进入 Cloudflare Pages Function，不再是“点完就没了”。这是最基础的用户入口。
Already Connected上传音频或视频后，系统会判断时长、音轨、静音、爆音，告诉用户这段素材能不能用来克隆。
Real Check微信、短信、语音、日记、视频字幕和家人描述进入本地记忆库，让回答的内容像那个人。
Memory Core温柔、沉默、责备、幽默、悲伤陪伴、呼吸停顿都拆成模块，避免回答像客服 AI。
Emotion Filled默认本地向量库，本地检索，本地保存。DeepSeek 只作为可选离线整理，不默认上传隐私聊天。
Local First用户开口后走 STT、记忆检索、语言生成、TTS 合成，目标是低延迟地听到那个人回应。
Voice PipelineVoice Stack
这一块讲清楚每个开源模块负责什么：谁负责听懂、谁负责克隆、谁负责说话、谁负责情绪、谁负责验证。先用免费本地路线跑通，再决定后面是否接付费服务。
先把上传的语音、视频、对话转成文字，并识别语言、时间戳和情绪线索。
从声音里提取情绪表征：悲伤、愤怒、温柔、压力、犹豫、疲惫。
把聊天记录和语音文字放进本地记忆库，找事实、口头禅、关系和禁忌。
负责音色克隆和声音设计，目标是让“嘴像”，支持中文、多语言和方言方向。
小模型，CPU 可跑。已经在 Mac 上生成出真实 wav，并通过 95.45% 声纹相似度测试。
负责长上下文、多说话人、情感对话，让声音能持续聊天，而不是只念一句台词。
情感对话和心理安慰方向，用来测试“怎么说才不像客服 AI”。
生成后必须跑声纹相似度。当前 demo 是 95.45%，超过 80% 验收线。
Voice Language System
Presence 不能只把按钮翻译成中文或英文。每一种语言都要能完成同一条链路：听懂上传素材、整理记忆、用那个人的语言习惯生成回答、再用相同音色和情绪说出来，并且跑声纹验收。
English, Chinese, Ukrainian, Russian, Japanese, Korean, Spanish, French, German, Arabic, Portuguese. 这是网站界面层。
中文、英文、日语、韩语、西语、法语、德语、俄语、阿语、葡语等声音输入输出要逐个验证，不靠翻译菜单冒充支持。
四川话、粤语、吴语、东北话、河南话、陕西话、山东话、天津话、闽南话这类方言要作为音色和说话习惯保存。
很多真实聊天会中英混说。系统需要保留“这个人什么时候切英语、什么时候说中文”的习惯。
不同语言里的温柔、责备、停顿和告别不一样。情绪模块必须按语言重写，不是统一模板翻译。
每种语言上线前都要有测试音频、生成音频和 ECAPA 声纹分数，目标仍然是 80% 以上。
Emotion Modules
Presence 最难的不是“说话”，是让它知道什么时候该沉默、什么时候该骂你、什么时候该先让你喝水。
“先喝口水，慢慢说。你不用在我这儿装没事。”
Personality / Memory System
微信导出、短信、语音、照片、视频字幕、日记、家人补充。
按说话人切分、去重、脱敏、标注关系和场景。
本地 LanceDB / sqlite-vec 建索引，数据默认不离开电脑。
按问题找事实、语气样本、相似情绪、禁忌和边界。
本地模型或可选 DeepSeek 生成短回复，语气守卫强制“像这个人”。
MOSS-TTS-Nano / VoxCPM2 / MOSS-TTSD 合成声音并流式播放。
30s Voice Clone Demo
这不是假装已经云端训练完成，而是把真实产品流程具象化：音频清洗、情绪抽取、音色克隆、台词生成、TTS 合成。先用免费本地模型跑成果。
上传后会生成本地免费模型路线，不会把文件传出去。

Privacy & Trust
Your voice, your words, your personality — these are not data points to us. They are someone's entire world. End-to-end encrypted, privately stored, never used to train other models. Ever.
Technology
Presence is the first AI system designed specifically for personality preservation — not general assistance, not entertainment, but the singular purpose of keeping a person's voice, warmth, and wisdom accessible to those who love them, forever.
Unlike general-purpose AI, Presence builds a private, individual model for each person — trained exclusively on their own words, recordings, and interactions. No shared weights. No blended personalities. Just them.
State-of-the-art voice cloning from as little as 3 minutes of audio. Presence captures pitch, cadence, accent, and the subtle emotional texture that makes a voice unmistakably theirs — then reproduces it in real time.
A proprietary activity-monitoring system that distinguishes absence from loss. Passive, respectful, and precise — it activates only when needed, reaching loved ones with care and the preserved voice of the person they miss.
End-to-end encrypted storage. Zero third-party access. Individual model isolation — your data never influences another person's AI. GDPR and CCPA compliant by design, with full deletion rights guaranteed.
