- OCR
- Extract text from the supplied image
- Detect the language of the text
- Support for
.pdf
,.png
,.jpeg
, and many more!
You can use so much of optiic
for free, but if you want to do some advanced stuff, you'll need an API key. You can get one by signing up for an account.
Install with npm if you plan to use optiic
in a Node project or in the browser.
npm install optiic
If you plan to use optiic
in a browser environment, you will probably need to use Webpack, Browserify, or a similar service to compile it.
const optiic = new (require('optiic'))({
apiKey: 'api_test_key' // Not required, but having one removes limits (get your key at https://optiic.dev).
});
Install with CDN if you plan to use Optiic only in a browser environment.
<script src="https://cdn.jsdelivr.net/npm/optiic@latest/dist/index.min.js"></script>
<script type="text/javascript">
let optiic = new Optiic({
apiKey: 'api_test_Key' // Not required, but having one removes limits (get your key at https://optiic.dev).
});
</script>
You can use optiic
in a variety of ways that require no installation, such as curl
in terminal/shell. See the Use without installation section below.
If you want to see how optiic
works, you can try a sample such as this image:
This will result in an output like this:
{
text: "We love Optiic!",
language: "en",
}
After you have followed the install step, you can start using optiic
to analyze images and perform OCR from within your app!
Submit and image to process and return the text in the image.
