Tutorial: Image Analysis

Goal: Extract text from an error dialog image that cannot be copied. Level: Intermediate Time: 1 minute

Prerequisites

• Vision-capable AI provider: Image analysis requires a provider that supports vision/multimodal capabilities:
  • OpenAI: GPT-5.1, o3
  • Anthropic: Claude Opus 4.5, Claude Sonnet 4.5, Claude Haiku 4.5
  • Google: Gemini 3 Pro, Gemini 3 Flash
  • xAI: Grok 4.1

Note: If your configured provider does not support image analysis, screenshot commands will not be available. Configure a vision-capable provider in Settings before using this feature.

Scenario

An application crashed and showed a popup error message. You can't select the text with your mouse to Google it.

Step 1: Capture

1. Press the Screenshot Hotkey (Ctrl+Shift+Alt+S).
2. The screen freezes and crosshairs appear.
3. Click and drag a box around the error dialog.

Step 2: Analyze

Once you release the mouse, the Rephlo Screenshot Analysis Result dialog appears.

1. Select the "Extract Text" command.
   • Instruction: "You are an OCR tool. Extract all visible text exactly as it appears."

Step 3: Result

Rephlo returns the raw text:

"Error 0x8004005: Unspecified error in module lib_core.dll at address 0x4f..."

Step 4: Solve

Now you can:

1. Copy the error code.
2. Run a "Troubleshoot" command on that extracted text to ask the AI how to fix it immediately.
