# Settings & Local AI Configuration

Configure general RenameClick settings and advanced Local AI options including model selection and performance tuning for power users.

## General Settings

### Theme

Light and dark mode support.

## Local AI Settings

The Local AI Settings panel is also a general power-user control panel that affects all providers.

### Server Port

| Setting | Value |
| --- | --- |
| Default | 8080 |
| Fallback | Auto-selects a free port if 8080 is occupied |

### Context Size

Controls how much context the local AI model uses for analysis. Larger context = better understanding of long documents, but uses more memory.

### Temperature

| Value | Behavior |
| --- | --- |
| Lower (0.0 - 0.3) | More deterministic, consistent results |
| Higher (0.7 - 1.0) | More creative, varied results |

### Prompt Length Limit

| Setting | Value |
| --- | --- |
| Default | 1,800 characters |
| Range | 500 — 4,000 characters |

### Text Trim Limit

Maximum characters extracted from documents before sending to AI. Longer documents are truncated.

| Setting | Value |
| --- | --- |
| Default | 4,500 characters |

Truncation strategy:

- **Head only**: First N characters
- **Head + Tail**: First N/2 and last N/2 characters (better for documents with signatures/summaries at the end)

### Max Categories Per Preset

| Setting | Value |
| --- | --- |
| Default | 8 |
| Range | 3 — 50 |

### Category Description Length Limit

| Setting | Value |
| --- | --- |
| Default | 100 characters |
| Range | 50 — 300 characters |

### Batch File Limit

| Setting | Value |
| --- | --- |
| Default | 30,000 files |
| Range | 30,000 — 500,000 files |

This limit affects Rename workspace, AI Search, and Auto Flow.
