# TalkPipe Writing Assistant

Making the AI write _with_ you, not _for_ you.

An AI-powered writing assistant that transforms how you create structured documents. This application combines intelligent content generation with intuitive document management, enabling writers to craft professional documents with contextually-aware AI assistance that understands your style, audience, and objectives.

Built on the [TalkPipe framework](https://github.com/sandialabs/talkpipe), this tool helps you:

- **Break writer's block**: Generate initial drafts and ideas for any section
- **Maintain consistency**: AI understands your document's context, style, and tone across all sections
- **Iterate quickly**: Multiple generation modes (rewrite, improve, proofread, ideas) let you refine content efficiently
- **Stay organized**: Structure documents into sections with main points and supporting text
- **Work offline**: Use local LLMs via Ollama or cloud-based models via OpenAI, Anthropic, and more

That's it! You're ready to use the AI writing assistant.

## Usage

### Starting the Server

```bash
# Default: http://localhost:8001
writing-assistant

# Custom port
writing-assistant --port 8080

# Custom host and port
writing-assistant --host 0.0.0.0 --port 8080

# Enable auto-reload for development
writing-assistant --reload

# Custom database location
writing-assistant --db-path /path/to/database.db

# Disable custom environment variables from UI (security)
writing-assistant --disable-custom-env-vars

# Initialize database without starting server
writing-assistant --init-db

# You can also use environment variables
WRITING_ASSISTANT_PORT=8080 writing-assistant
WRITING_ASSISTANT_RELOAD=true writing-assistant
WRITING_ASSISTANT_DB_PATH=/path/to/database.db writing-assistant
```

When the server starts, it will display:
- The URL to access the application
- Registration and login URLs
- API documentation URL
- Database location

**Authentication:** The application uses JWT-based multi-user authentication with FastAPI Users. Each user has their own account with secure password storage. New users can register through the web interface at `/register`, and existing users log in at `/login`.

### Environment Variables

Configure the application with these environment variables:

| Variable | Description | Default |
|----------|-------------|---------|
| `WRITING_ASSISTANT_HOST` | Server host address | `localhost` |
| `WRITING_ASSISTANT_PORT` | Server port number | `8001` |
| `WRITING_ASSISTANT_RELOAD` | Enable auto-reload (development) | `false` |
| `WRITING_ASSISTANT_DB_PATH` | Database file location | `~/.writing_assistant/writing_assistant.db` |
| `WRITING_ASSISTANT_SECRET` | JWT secret key for authentication | Auto-generated (change in production) |
| `TALKPIPE_OLLAMA_BASE_URL` | Ollama server URL for local models | `http://localhost:11434` |


**Security Options:**
- `--disable-custom-env-vars`: Prevents users from configuring environment variables through the browser interface
  - Use this for shared deployments or when you want centralized credential management
  - Environment variables must be set at the server level (via shell environment)
  - The Environment Variables section will be hidden in the UI


**Configure document metadata**:
   - AI Source: `openai`, `anthropic`, or `ollama`
   - Model: e.g., `gpt-4`, `claude-3-5-sonnet-20241022`, or `llama3.1:8b`
   - Writing style: formal, casual, technical, etc.
   - Target audience: general public, experts, students, etc.
   - Tone: neutral, persuasive, informative, etc.
   - Word limit: approximate words per paragraph

### Document Storage

Documents are stored in an SQLite database with multi-user isolation:

**Default Location:** `~/.writing_assistant/writing_assistant.db`

**Custom Location:** Use `--db-path` or `WRITING_ASSISTANT_DB_PATH` to specify an alternative location

**Features:**
- Per-user document isolation (users only see their own documents)
- Automatic snapshot management (keeps 10 most recent versions)
- User-specific preferences (AI settings, writing style, etc.)
- Cascade deletion (removing a user deletes all their documents)

**Backup:** Simply copy the database file to create a backup. The database can be moved to a different location using the `--db-path` option.

## Troubleshooting

### Application Issues

**"Port already in use"**
- Change the port: `writing-assistant --port 8080`
- Or kill the process using the port

**"Cannot save document"** or **"Database error"**
- Check write permissions to the database directory (default: `~/.writing_assistant/`)
- Ensure the directory exists: `mkdir -p ~/.writing_assistant`
- Try a different database location: `writing-assistant --db-path /tmp/test.db`
- Initialize the database manually: `writing-assistant --init-db`

**"Authentication failed"** or **"Invalid credentials"**
- Double-check your email and password
- Register a new account if you haven't already
- The database may have been reset - check the database location

**"Cannot connect to database"**
- Verify the database file exists and is not corrupted
- Check file permissions on the database file
- Try initializing a new database: `writing-assistant --db-path /tmp/new.db --init-db`
