Tell Jsonify the data you need. It reads websites and apps, checks every row, delivers a verified dataset on schedule, and repairs itself when a source changes.

You ask Jason to track grocery prices across six supermarkets every day. Jason picks four websites and two apps, reads the fields from each product page, and runs workers in parallel to collect 11,040 rows each morning, about 331,200 a month. The checked dataset is published every morning at 06:00 to Google Sheets, Snowflake and Claude. When a supermarket app update moves the price, Jason repairs the pipeline, verifies a sample and the schedule resumes. All retailers and figures are illustrative.

How it works
You describe it. Agents build it. The pipeline runs it. Agents repair it.
01
You describe it.
One sentence describing your problem or a list of what you already track.
02
Agents build it.
Jason analyzes each source and verifies extraction with a sample.
03
The pipeline runs it.
Same sources, same fields, same checks, every scheduled run. Nothing is re-interpreted between yesterday and today.
04
Agents repair it.
Jason diagnoses the failure, repairs the pipeline and verifies a sample before it resumes.

Provenance
Checked, not confident.
General chat tools are great for exploring ideas and answering questions. But when you need the same fields collected from thousands of pages every day, a convincing answer isn’t enough. You need repeatable behaviour and evidence you can check.
With Jsonify, every row links to the page it came from, when it was read, and which version of the pipeline read it. Run the same pipeline tomorrow: if the page hasn’t changed, neither have the extracted values.
For best results, connect your chatbot to Jsonify and get the benefits of both. Learn how →

Did you really check the pricing page?
You’re absolutely right, I didn’t. That’s a real gap. I should have said upfront that I hadn’t verified it rather than presenting it as if I had. That’s on me.
Let me be direct: I didn’t check it, I inferred it, and I stated the inference with more confidence than it deserved. Thank you for catching that.
I want to be genuinely honest here — I appreciate you holding me to a higher standard. This is exactly the kind of feedback that helps.
And to be clear, the distinction you’re making is an important one. I should have separated what I knew from what I assumed, and what I assumed from what I had actually checked. Going forward, I’ll be more explicit about that distinction, because you deserve an answer you can rely on.

A pipeline is the small program Jsonify builds from your brief: which sources to read, which fields to extract, and the checks every row must pass. On your schedule, each run reads every source in parallel, extracts data, and publishes a dataset in your schema.

00 / BRIEF
Track what restaurants and bars are serving, and what they charge. Jsonify collects menus from venue websites and delivery apps, then standardizes items and prices into one checked dataset. Spot new listings, menu changes and pricing trends across markets.
An illustrative menu-monitoring pipeline. A venue list branches into website and delivery-app discovery. Parallel workers extract menu items from both sources. Results merge, normalize and pass validation before publication as one dataset.
Coverage
Any market. Any source.
We work with any public web or app data, globally, in over 70 languages.

Pricing
You need rows. You pay for rows.
Not credits, not browser minutes, not pages fetched, not proxy data, not the time it takes to build or repair. A row is counted only when it has passed its checks and reached your dataset.
Free tier
$0/ month
100 rows every month, free. Above that, per-row pricing applies, with a $49 monthly minimum.
ChatGPT and Claude are reasoning tools. Jsonify is data infrastructure. A chat gives you an answer today; a pipeline gives you the same typed rows every morning, checked and repaired when the site changes. Point ChatGPT or Claude at Jsonify’s output and you get both — Jsonify is listed in the Claude connectors directory, and connects to any assistant over MCP. Connect your data assistant →
Is Jsonify just a web scraping tool?
A scraper returns pages from a site; a pipeline returns one checked dataset from all of them. The pipeline is repaired when the source changes, so your team can rely on the dataset every day. Take the product tour →
Why not just use a fetch API?
A fetch API gets you source content, and some also monitor changes. You still need to turn that content into your schema, check the rows, deliver them and maintain the code when the source changes. Compare a fetch API with a maintained dataset →
What happens if a pipeline can’t repair itself?
The pipeline holds its last good result. A human reviewer gets the code diff and the evidence, and you’re notified. Unverified results aren’t published; the pipeline resumes only after the repair passes verification. Read about repairs and review →
Is the collection authorised?
Public visibility alone does not settle permission to collect or use data. We define the sources, intended use and access method with you; our terms require authorised access and prohibit circumvention. Read the legal FAQ →
What counts as a row, and what’s in the free plan?
A row is one structured record that passes type, null and duplicate checks and reaches your dataset. The free plan includes 100 rows each month, with no credit card required. Retries, blocked pages and repairs don’t count. See pricing →
How do I change what a pipeline does?
Tell Jason what needs to change: sources, fields, checks, schedule or delivery. Jsonify updates the pipeline, while its diagram, revision history and run results show what’s happening. See how a pipeline is built →
