Jsonify is an AI "data intern" in the cloud -- an intelligent AI agent that can automate data collection and maintenance tasks involving the web and documents. We automate the collection and maintenance of your entire web data pipeline, end-to-end. Jsonify visits websites, understands them in the same way a human does, navigates the website to find the data you want, extracts it, validates results, and synchronizes it somewhere useful for you โ all from our dashboard.
The no-code workflow builder lets you easily script varied tasks. For example: - "every day, go to each of these companies, navigate to the team page, find the LinkedIn of each team member, and save their technical lead to a Google Doc" - "every week, visit these 500,000 company websites, find their jobs page, and send the list of their jobs to Airtable" - "build a spreadsheet of the competitive landscape of AI data startups" - "monitor our competitors products and email me when something is cheaper than ours"

Braintrust focuses on evaluation-driven development: the idea that monitoring LLM applications means continuously scoring outputs against quality criteria, not just tracking latency and error rates. It's an eval platform first, with observability features built on top of the evaluation infrastructure. - Source: dev.to / 2 months ago
You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / 3 months ago
Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline โ the metadata.userId pattern is the universal part. - Source: dev.to / 3 months ago
