# `OCRTool`
|
||
|
||
## Description
|
||
|
||
Extract text from images (local path or URL). Uses a vision‑capable LLM via CrewAI’s LLM interface.
|
||
|
||
## Installation
|
||
|
||
No extra install beyond `crewai-tools`. Ensure your selected LLM supports vision.
|
||
|
||
## Parameters
|
||
|
||
### Run Parameters
|
||
|
||
- `image_path_url` (str, required): Local image path or HTTP(S) URL.
|
||
|
||
## Examples
|
||
|
||
### Direct usage
|
||
|
||
```python Code
|
||
from crewai_tools import OCRTool
|
||
|
||
print(OCRTool().run(image_path_url="/tmp/receipt.png"))
|
||
```
|
||
|
||
### With an agent
|
||
|
||
```python Code
|
||
from crewai import Agent, Task, Crew
|
||
from crewai_tools import OCRTool
|
||
|
||
ocr = OCRTool()
|
||
|
||
agent = Agent(
|
||
role="OCR",
|
||
goal="Extract text",
|
||
tools=[ocr],
|
||
)
|
||
|
||
task = Task(
|
||
description="Extract text from https://example.com/invoice.jpg",
|
||
expected_output="All detected text in plain text",
|
||
agent=agent,
|
||
)
|
||
|
||
crew = Crew(agents=[agent], tasks=[task])
|
||
result = crew.kickoff()
|
||
```
|
||
|
||
## Notes
|
||
|
||
- Ensure the selected LLM supports image inputs.
|
||
- For large images, consider downscaling to reduce token usage.
|
||
- You can pass a specific LLM instance to the tool (e.g., `LLM(model="gpt-4o")`) if needed, matching the README guidance.
|
||
|
||
## Example
|
||
|
||
```python Code
|
||
from crewai import Agent, Task, Crew
|
||
from crewai_tools import OCRTool
|
||
|
||
tool = OCRTool()
|
||
|
||
agent = Agent(

role="OCR Specialist",
|
||
goal="Extract text from images",
|
||
backstory="Vision‑enabled analyst",
|
||
tools=[tool],
|
||

|
||
expected_output="All detected text in plain text",
|
||
agent=agent,
