# Interbang

> Interbang is a moderated usability testing (UT) tool that links session notes to the recording transcript and turns them into a shareable report the moment the session ends — without the busywork of stitching several tools together.

Every page is also available in Korean under /ko (e.g. /ko/blog).

## Usability testing guides
- [How far can Zoom, Notion, and a spreadsheet carry a usability test?](https://interbang.app/en/blog/usability-testing-spreadsheet-template): The free stack runs a real usability test. Here are the templates that make it work, and the three structural gaps that decide when it stops being enough.
- [How to moderate a usability test: what to say when a participant gets stuck](https://interbang.app/en/blog/moderate-usability-test): A participant freezes and every instinct says help. Moderating is mostly learning what to say instead, and when to say nothing at all.
- [The test is over. Now what do you do with all these notes?](https://interbang.app/en/blog/analyze-usability-test-results): Five sessions leave you with a hundred notes. This is the three-step method that turns them into the three fixes your team will actually make.
- [Write usability test tasks as scenarios, not instructions](https://interbang.app/en/blog/usability-test-tasks): The moment you write "Click Sign up," the participant only has to find that word on the screen. A good task gives a goal and makes them figure out the rest.
- [Best usability testing tools: pick for your job and your budget](https://interbang.app/en/blog/usability-testing-tools): There is no single best usability testing tool. The category splits into three jobs, and the right pick depends on which one you are doing right now.
- [How many users does a usability test need? Why 5 isn't always the answer](https://interbang.app/en/blog/usability-testing-participants): About 5 users find ~85% of usability problems. But "5" is an average for one case. The moment your goal shifts, so does the number.
- [Numbers tell you what's wrong. Usability testing tells you why.](https://interbang.app/en/blog/what-is-usability-testing): Numbers show you where users drop off, not why. Usability testing is how you find the why, and fix it.
