Survey Open Ends Coding Made Quick & Easy

Manually coding open-ends can take days. Blix turns it into minutes.

Blix is built with a simple goal: to help researchers analyze open-ended survey data as quickly and easily as numbers in a spreadsheet.

We’re building it hand-in-hand with our customers to deliver human-level coding in minutes, in a platform that’s intuitive, fast, and easy for any researcher to use.

What You Can Do with Blix

Common Questions

I’ve used other coding tools in the past, they don’t work like humans.
You’re right, most traditional AI coding tools rely on keyword matching.

Blix is different. It uses large language models that understand context and nuance to code based on meaning, not just words, just like humans do.

That means it codes like a human researcher would, only 100x faster.

Is Blix complicated to use?
Not at all. Blix is designed to be simple and intuitive. Just upload your survey data file, click “Analyze,” and you’re nearly done. No setup, no long training, no IT support required.

How long does it take to code my data?
Most projects are analyzed in minutes. You’ll spend more time sipping coffee than coding.

Will my data be private and secure?
Yes. Blix runs in a secure, enterprise-grade environment where your data is used only for your research, never for training AI models. We are GDPR-compliant and trusted by leading research agencies and global brands around the world.

Why not just use ChatGPT?
ChatGPT is great for general tasks, but it’s not built for the scale, reliability, or security that professional research requires. Blix is purpose-built for researchers — you can upload raw survey data, apply structured codeframes, adjust coding on the fly, export to Excel or PowerPoint, generate summaries and quotes, translate responses, and handle trackers and multilingual projects with ease. It’s fast, secure, and built to fit your workflow — so you can focus on insights, not workarounds.

How much does it cost?
You can start free with 2,000 coded responses. After that, we offer:

• A flexible pay-as-you-go plan (monthly payment according to your usage, no commitment), or
• Annual subscriptions, with 20% off for the first year.
