| # LineChatbot | |
| A Streamlit chat app that role-plays a conversation partner using the Claude API, | |
| with optional persona/relationship analysis from an uploaded LINE chat export. | |
| This README's YAML header configures it as a **Docker** Hugging Face Space. | |
| ## How access works | |
| - **Passkey gate** — if the `APP_PASSKEY` secret is set, visitors must enter it to | |
| use the app. Share the passkey with whoever you want to let in. | |
| - **API key** — if the `ANTHROPIC_API_KEY` secret is set, everyone who passes the | |
| passkey gate uses *your* key automatically. If it is **not** set, each visitor is | |
| asked to paste their own Anthropic key (kept only in their session, never saved). | |
| - **Per-user isolation** — every browser session gets its own data directory, so | |
| visitors never see or overwrite each other's conversations. | |
| ## Deploy to Hugging Face Spaces | |
| 1. Create a Space: <https://huggingface.co/new-space> → **SDK: Docker** → blank. | |
| 2. Push **this folder** (`romance-chatbot/`) as the Space repo root. The 1.1 GB | |
| `model.pt` checkpoint must go through Git LFS (`.gitattributes` already tracks | |
| `*.pt`): | |
| ```bash | |
| cd LineChatbot | |
| git init | |
| git lfs install | |
| git remote add origin https://huggingface.co/spaces/<you>/<space-name> | |
| git add . | |
| git commit -m "Deploy LineChatbot" | |
| git push origin main | |
| ``` | |
| 3. In the Space: **Settings → Variables and secrets**, add: | |
| - `APP_PASSKEY` = the shared passkey you'll hand out (recommended). | |
| - `ANTHROPIC_API_KEY` = your Claude key *(optional — omit to make each visitor | |
| supply their own)*. | |
| - `CHAT_MODEL` *(optional, default `claude-haiku-4-5`)*. | |
| 4. The Space builds the Docker image and gives you a shareable URL. First use of the | |
| persona analysis / summarizer downloads the local models (a few GB) once. | |
| > Free CPU hardware works but the local models are slow on first use. Personality/ | |
| > emotion analysis runs once at setup; summarization runs every 20 messages. | |
| ## Run locally | |
| ```bash | |
| cd romance-chatbot | |
| pip install -r requirements.txt # torch CPU/GPU per your platform | |
| export ANTHROPIC_API_KEY=sk-ant-... # or paste it in the UI | |
| # export APP_PASSKEY=letmein # optional gate | |
| streamlit run core/app.py | |
| ``` | |
| ## Configuration (env vars / Space secrets) | |
| | Variable | Required | Purpose | | |
| |---------------------|----------|----------------------------------------------------------------| | |
| | `APP_PASSKEY` | no | Shared passkey gate. Unset = no gate. | | |
| | `ANTHROPIC_API_KEY` | no | Server-side Claude key. Unset = visitors paste their own. | | |
| | `CHAT_MODEL` | no | Claude model id (default `claude-haiku-4-5`). | | |
| | `MAX_OUTPUT_TOKENS` | no | Max reply length (default 256). | | |
