How to Use Chinho

Everything you need to know to start earning by annotating Bengali AI data.

01

Create Your Account

Go to the Join page, enter your email and create a password. Open the confirmation link we email you, then fill in your profile — your name, university, and payout details (bKash or Nagad number).

Use an email you check regularly — the confirmation link goes there.
Double-check your bKash/Nagad number — that’s where your earnings go.
02

Take the Entry Test

Before you can start earning, you’ll take a short 6-question test. It checks your annotation judgment, not trivia. You need 4 out of 6 to pass. It takes about 5 minutes.

Read both AI responses carefully before choosing.
You can retake the test if you don’t pass the first time.
03

Choose a Project

Your dashboard shows all available projects. Each project type involves a different kind of task — from comparing AI responses to tagging entities, labeling sentiment, or recording voice. Pick whichever interests you.

You can work on multiple project types — there’s no limit.
Projects without active batches will show “No batches available” — check back later.
04

Complete Tasks

Inside each workspace, select a batch, then the system gives you tasks one at a time. Read the prompt, fill in the required fields, and submit. If a task is unclear, skip it — skipping never hurts your score.

Take your time — quality matters more than speed.
About 10% of tasks are quality checks. You get paid for those too, even if you miss them.
Tasks expire after 24 hours if not submitted.
05

Track Your Progress

Your dashboard shows tasks completed, earnings, quality score (after 20 checked tasks), and a 4-week activity heatmap. Your quality score is the pass rate of your last 50 reviewed or expert-checked tasks, and it decides your tier bonus.

Every task pays the same rate, regardless of your score.
Switch between English and Bengali using the language button.
06

Get Paid

Once your balance reaches ৳100, request a payout from the dashboard. Choose bKash or Nagad, confirm the amount, and you’ll receive it within 24 hours.

Minimum payout is ৳100.
Payouts are processed within 24 hours — usually much faster.
You can update your payout number anytime from your profile.
