WeClone distills your identity, goals, preferences and current situation from your digital life into a life portrait, organized into domains such as work, family and health, that you can review, trace and share on your own terms. The portrait serves as long-term memory for your AI assistants and will power clones with your personal style.
✨ Core Features
- 🗺️ Interactive life portrait: your portrait is organized by domain and topic. Every fact traces back to its source and can be reviewed and edited. Extraction runs through Codex or any OpenAI-compatible API.
- 🎭 Your own AI clone: fine-tune an open model on your chat history and deploy it to Telegram, Discord, Slack, Feishu and more through AstrBot or LangBot. Training data is filtered for personal information.
- 🧠 Connect AI assistants: Claude Code, Codex and other assistants read your portrait and domain summaries over MCP. You choose which domains and privacy levels they can read.
- 🗣️ Speaking style analysis: 179 style features in ten categories, covering vocabulary, syntax, tone, emotion, rhetoric and conversational rhythm.
- 🤖 Agent clone (in development): no training required. A large model drives the clone in real time from your portrait, memories and speaking style.
- 🔒 Privacy first: encrypted local storage by default, a privacy level on every fact, and full control over what is exported and shared.
[!NOTE]
WeClone now goes beyond fine-tuned clones. The original fine-tuning workflow remains fully supported, see Fine-tuned clone.
The portrait and its extraction prompts are currently in Chinese, and English chats have not been tested yet. The web UI is available in English and Chinese.

📥 Supported Data Sources
The life portrait reads text messages only. The table shows the message types the fine-tuned clone supports. See Preparing data for exporting and setup.
| Platform | Text | Images | Voice | Video | Animated Emojis/Stickers | Links (Sharing) | Quote | Forward | Location | Files |
|---|
| Telegram | ✅ | ✅ | ❌ | ❌ | ⚠️ Converted to Emoji | ❌ | ❌ | ✅ | ✅ | ❌ |
| WhatsApp | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 |
| Discord | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 |
| Slack | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 | 🚧 |
Chats from other platforms can be converted to WeClone's generic CSV format and placed in dataset/csv/. See Preparing Data on the docs site for the format.
🚀 Quick Start
1. Install
Python 3.12 is required. uv is recommended:
git clone https://github.com/xming521/WeClone.git && cd WeClone
uv venv .venv --python=3.12
source .venv/bin/activate # Windows: .venv\Scripts\activate
uv pip install -e .
cp settings.template.jsonc settings.jsonc
All settings live in settings.jsonc. The base install is enough to build your portrait and connect assistants. By default the portrait is extracted through the Codex CLI, which must be installed and signed in. Any OpenAI-compatible API works as well, see Installation and configuration.
2. Prepare your data
Telegram chats are supported today. Export them as JSON with Telegram Desktop, put the ChatExport_* folders in dataset/telegram/, then set platform to telegram and telegram_args.my_id to your user ID in settings.jsonc. Chats from other platforms can be converted to the generic CSV format and placed in dataset/csv/. See Preparing data.
3. Build your portrait and connect assistants
weclone-cli server
Open http://127.0.0.1:5175, set a password, and build your portrait on the Build portrait page, which checks the setup and shows the progress. Then review your portrait fact by fact, approve the summaries on the Summaries page, then generate a token on the Assistants page and run the commands it shows for Claude Code or Codex. See Life portrait and assistants.
4. Fine-tune a clone
An NVIDIA GPU is required. The default Qwen2.5-7B-Instruct with LoRA needs about 16GB of VRAM. Install the dependencies and download the model as described in Fine-tuned clone, then run:
weclone-cli make-dataset # build training data, filtering personal information
weclone-cli train-sft # LoRA fine-tuning
weclone-cli server --inference --port 8005 # OpenAI-compatible API
Connect the trained clone to chat platforms through AstrBot or LangBot, see Chat bots.
🔒 Privacy and Security
- Model services during extraction: while building your portrait, chat content is sent to the model service you configured, after you confirm. Content already extracted is read from a local cache and not sent again.
- Encrypted by default: the chat snapshot, portrait, training data and fine-tuned model are stored encrypted on your machine, with one password shared by the web UI and the command line.
- Access on your terms: every fact carries a privacy level (public, normal, private, sensitive), and you set in the web UI which domains assistants can read and up to which level.
- Training data filtering: Microsoft Presidio and your own blocked words remove personal information before fine-tuning, though 100% detection is not guaranteed.
See Security.

⚠️ Disclaimer
[!IMPORTANT]
This project is intended for learning and research. Assess the risks yourself before using it in production or offering it as a service.
- Provided as is: the project comes without warranties of any kind. The authors are not liable for any direct or indirect loss arising from its use and do not commit to ongoing maintenance or support.
- Data and consent: chat history contains other people's messages. Make sure that collecting and using the data complies with local laws and that the people involved have consented.
- Portrait extraction by LLMs: while your portrait is built, chat content, including the other side's messages, is sent to the model service you configured and handled under that service's data policy. Choose a provider you trust and check its data retention and training terms. Leave chats you don't want sent out of the data directory.
- Portrait content: the portrait collects and infers personal information about you, touches on the people around you, and may include sensitive topics such as health or relationships. Keep result directories and exported files safe, and review the portrait before giving assistants access.
- Model output: portraits, summaries and clone replies are generated by models. They may be inaccurate and do not represent the real views of you or anyone else.
- AI disclosure: when a clone talks to other people, make clear that it is an AI so that no one mistakes it for a real person.
- Lawful use: do not use this project for any unlawful purpose.
This disclaimer may be revised as the project evolves.
