Free Usage Guide for Students and Researchers

Bareun (bareun) is free for students and researchers who use it for research purposes. You can use Korean morphological analysis and the spell checker in papers, experiments, and learning projects without worrying about cost. This page summarizes, in one place, how students and researchers can get started with Bareun for free.

Is it really free for students?

Yes. Morphological analysis is free for individuals, schools, and research institutions when used for research purposes. The lightest way to start is the free tier of 50,000 word units (eojeol) on the cloud (api.bareun.ai). You don't need to install anything. Just get an API key and you can start analyzing right away. For the overall licensing policy, see License Policy at a Glance.

Three paths open to students and researchers

Cloud free tier: Free up to 50,000 eojeol. All you need is an API key after signing up.
Free research-purpose application: After review of your application, both morphological analysis and spell checking are free.
Free installable edition: The self-hosted morphological analyzer is free for non-commercial use.

1. Start with the cloud free tier

!pip install bareunpy

from bareunpy import Tagger
API_KEY = "koba-ABCDEFG-1234567-LMNOPQR-7654321"  # replace with your own key
tagger = Tagger(API_KEY, 'api.bareun.ai', 443)
res = tagger.tags(["형태소 분석을 연구에 활용합니다."])  # "We use morphological analysis in our research."
print(res.pos())

Once logged in, you can view usage statistics in real time, so you can see how much of the 50,000-eojeol free tier you have used.

2. Practice with Google Colab

If you don't have a suitable environment to install things in, Google Colab is the easiest option. Open a notebook in your browser, install the library with !pip install bareunpy, and connect to the cloud server (api.bareun.ai, port 443) as in the code above. You can start practicing morphological analysis right away, with no server to set up. For a step-by-step walkthrough, see Getting Started with Colab.

3. Apply for free research-purpose access

If you need large-scale analysis beyond the free tier, or want free access to the spell checker, use the free research-purpose application.

Free research-purpose application

Both morphological analysis and the spell checking service are free for research purposes. Submit an application stating the research title, purpose, methods and content, expected outcomes, acknowledgment, and whether the research will be made public. We will approve it after review. There is no dedicated web page for this yet. Please feel free to email helpdesk@bareun.ai, and we will enable cloud access for you directly.

Please include an acknowledgment that you used Bareun in your research output.
