On the phone, a study question, “How easy is it to see a doctor when you need one?”, is shown in turn in Arabic, Spanish, Hindi, Swahili, Chinese, French, Yoruba, Japanese, Portuguese, Igbo, Korean and Hausa. One question, in each person’s own language. Behind it, a real Surdatics Report, from a study of 334 approved responses.

How it works
1Create
Describe it in a sentence or two. Surdatics AI drafts the study in your language, and you edit every word.


The new AI feature is very nice — I just gave the description and it generated all the questions, very similar to what I had already created. I commend you and your team for the good work.
2Reach and verify
Choose who should answer and see how many verified people match before you pay. Or share the study with your own people by link or QR code.

3Analyse and prove
Results update as answers are approved, with a significance test on every comparison between groups. Your Surdatics Report links every number to its table, and anyone can verify the data on the blockchain.

For people who answer
Answer real studies in your own language, on your phone.
On a study with a reward, you earn SURDA when the research team approves your answer, once you are verified and your profile is complete. If you agreed, you earn again when your data is resold. Each study shows whether its reward can be cashed out.
How rewards workResearch teams see a wallet address, never your name, email or phone. Surdatics Verify keeps no photo.
Settle disputed answers by anonymous vote, and earn a reward for each review.
5 questions a day. Guess how verified people around the world answered, then add your own answers.
A plan buys the tools. Rewards for the people who answer are set by you for each study, and our share is inside that budget, never added on top.

Universities, schools, students and registered non-profits: 30% off plans for 12 months, after a quick check. Rewards are not discounted.
A new development-effectiveness report points to a persistent gap between commitments to country ownership and the information used to manage aid. Research teams should treat that gap as a question about who can inspect, challenge and use the evidence.
56.8% of respondents who answered the storage-access question said they lacked access to proper storage or cold rooms. Respondents also frequently selected bad roads as a transport challenge and better storage as a way to reduce waste.
Afrobarometer’s survey puts everyday service and livelihood concerns beside the agendas of development-cooperation experts. The useful lesson is not to discard long-term reform, but to test whether it answers the problems citizens actually name.

Only verified people earn rewards. Today each person verifies once, with a one-minute face check: one real person, one account, with no ID card and no photo kept. Your results show the share of answers from verified people.
That your data has not changed since it arrived, and when it arrived. Each new answer gets a SHA-256 hash the moment it arrives, and the hashes are anchored on the blockchain. Anyone can verify a study or a single answer, with no account. Only the SHA-256 hash goes on the blockchain, never the answers or anyone’s details.
Yes. Field teams collect offline with ODK Collect or KoboCollect on Android phones, into the same dataset. Offline fieldwork comes with the Researcher plan and above. Studies run in many languages, right-to-left included, and your team checks every translated line before launch.
No. Code computes every figure from approved answers. Surdatics Report explains them, every number opens the table behind it, and any sentence with a number that is not in your data is removed.
On a study with a reward, each approved answer earns a reward in SURDA in the person’s Surdatics wallet. They need to be verified, with a complete profile. If they agreed to resale, they earn a share again when their data is resold. Cash-out is coming.
Your team approves each answer before it earns a reward. If a rejected answer is disputed, validators decide: verified people who are not the researcher, who vote anonymously and are rewarded for each review. Datasets collected here carry a data quality score on the Surdatics Data Marketplace.
The Free plan includes 100 responses a month, with every answer anchored on the blockchain.
