sidebarTitle: 'SillyTavern'
---
Give your SillyTavern characters long-term memory. Honcho remembers who you are, what you've talked about, and how to talk to you -- across sessions, characters, and restarts.
The extension has two parts: a **client extension** (browser) that hooks into SillyTavern events, and a **server plugin** (Node.js) that proxies requests to the Honcho API.
## Quick Start
### Step 1: Get Your Honcho API Key
1. Go to **[app.honcho.dev](https://app.honcho.dev)**
2. Sign up or log in
3. Copy your API key
### Step 2: Install
From your **SillyTavern directory**:
**macOS / Linux:**
```bash
bash <(curl -s https://raw.githubusercontent.com/plastic-labs/sillytavern-honcho/main/install.sh)
```
**Windows (PowerShell):**
```powershell
irm https://raw.githubusercontent.com/plastic-labs/sillytavern-honcho/main/install.ps1 | iex
```
<Note>
Server plugins must be enabled. The installer checks for this, but if you haven't already, add `enableServerPlugins: true` to your `config.yaml`.
</Note>
The installer:
1. Clones the extension into `public/scripts/extensions/third-party/sillytavern-honcho`
2. Symlinks the server plugin to `plugins/honcho-proxy`
3. Installs the `@honcho-ai/sdk` dependency
4. Detects your `~/.honcho/config.json` if it exists
### Step 3: Restart SillyTavern
Stop and restart SillyTavern so the server plugin loads.
### Step 4: Configure
Open **Extensions** (puzzle piece icon) and expand **Honcho Memory**:
1. Check **Enable Honcho Memory**
2. Click the API key field to set your key
3. Enter your workspace ID
4. Status indicator should show **Ready**
## Global Config (Multi-Tool Setups)
If you already use Honcho with other tools (Claude Code, Cursor, Hermes), the extension auto-populates settings from `~/.honcho/config.json`:
```json
{
"apiKey": "your-honcho-api-key",
"peerName": "your-name",
"workspace": "sillytavern",
"enabled": true
}
```
Config reads fall back from `hosts.sillytavern` to root-level globals. Writes are always scoped to `hosts.sillytavern` -- the extension never mutates settings for other tools.
```jsonc
{
"apiKey": "hch-v2-...",
"peerName": "alice",
"hosts": {
"sillytavern": {
"workspace": "sillytavern",
"aiPeer": "Assistant" // Updated automatically per character
},
"claude_code": { "..." : "..." },
"cursor": { "..." : "..." }
}
}
```
## How It Works
### Context Architecture
Every generation injects a **base context layer** from `session.context()` -- the peer representation (what Honcho knows about you) and session summary. This uses stale-while-revalidate caching: the first turn blocks to populate the cache, then every subsequent turn serves the cached result instantly while refreshing in the background.
The **enrichment mode** controls what layers on top of the base context:
| Mode | Behavior |
| --- | --- |
| **Context only** | Base layer only -- peer representation + session summary |
| **Reasoning** (default) | Base layer + dialectic `peer.chat()` queries on a configurable interval |
| **Tool call** | Base layer + function tools the LLM can call on demand |
Both the context and reasoning layers use stale-while-revalidate with configurable refresh intervals. After the first turn of a session, there is zero added latency.
### Tool Call Mode
In tool call mode, the extension registers three function tools that the LLM can invoke:
| Tool | Description |
| --- | --- |
| `honcho_query_memory` | Dialectic chat query -- ask Honcho what it knows |
| `honcho_save_observation` | Save an insight about the user to memory |
| `honcho_search_history` | Semantic search across session messages |
This mode works best with models that support function calling. The LLM decides when to query memory rather than firing on every turn.
### Peer Modes
| Mode | Behavior |
| --- | --- |
| **Single peer** | One user peer shared across all characters |
| **Per-persona** | Each character gets its own isolated memory |
### Session Naming
| Mode | Behavior |
| --- | --- |
| **Auto** | Per-chat hash (unique per conversation) |
| **Per-character** | One session per character (persistent) |
| **Custom** | User-defined session name |
### Event Flow
| SillyTavern Event | Action |
| --- | --- |
| Chat opened | Creates or retrieves Honcho session + peers |
| Before generation | Injects memory context into the prompt |
| User sends message | Stores message in Honcho session |
| AI responds | Stores response in Honcho session |
## Architecture
```
Browser (Client Extension) Server (Plugin)
+-----------------------+ +------------------------------+
| index.js | fetch() | plugin/index.js |
| | ------------> | |
| - Settings UI | /api/plugins/ | - Express router (7 routes) |
| - Event hooks | honcho-proxy | - Honcho SDK (@honcho-ai/sdk)|
| - Prompt injection | | - API key from ST secrets or |
| - Tool registration | | ~/.honcho/config.json |
+-----------------------+ +------------------------------+
```
The server plugin reads API credentials from SillyTavern's secrets store first, falling back to `~/.honcho/config.json`. It re-reads the global config before every write to prevent race conditions with concurrent tools.
## Troubleshooting
| Symptom | Fix |
| --- | --- |
| No "Honcho Memory" in Extensions | Check symlink exists: `ls public/scripts/extensions/third-party/sillytavern-honcho/manifest.json` |
| Plugin not initializing | Ensure `enableServerPlugins: true` in `config.yaml`, then restart ST |
| 403 on plugin requests | Set Honcho API key in extension settings or `~/.honcho/config.json` |
| SDK import error | Run `cd plugins/honcho-proxy && npm install` |
| Extension loads but nothing happens | Enable the checkbox and ensure workspace ID is set |
