Shadowfax AI – an agentic workhorse to 10x data analysts productivity
Hi HN, We built an AI agent for data analysts that turns the soul crushing spreadsheet & BI tool grind into a fast, verifiable and joyful experience. Early users reported going from hours to minutes on common real-world data wrangling tasks. It's much smarter than an Excel copilot: immutable data steps, a DAG of SQL views, and DuckDB for instant crunching over millions of rows. Our early agent prototype ranked #1 on the Spider2-DBT bench. https://spider2-sql.github.io Try it out and we'd love your feedback! Thanks, Di Wu & the Shadowfax team P.S. Shadowfax is Gandalf's horse from…

In plain words
Shadowfax AI is an AI agent designed for data analysts to accelerate data wrangling and analysis tasks. It uses immutable data steps, SQL views organized in a directed acyclic graph, and DuckDB to process large datasets quickly. The tool reportedly reduces hours-long tasks to minutes. It is built for analysts working with spreadsheets and business intelligence tools who want faster, verifiable results without manual data manipulation.

From the sources
AI-native analytics to think faster and better than ever before. Built from the ground up for intelligent workflows.
Turn messy data into repeatable, interactive analyses, with an audit trail you can explain in exec review. No Python required. Another day, another complex analysis request. The backlog grows. You tried another spreadsheet copilot. It failed spectacularly... again. You're tempted to vibe code it, but "AI said so" won't survive the CFO review. So you go back to manual work and start planning that "learn Python" sabbatical. This isn't a "we need a smarter model" problem. It's a legacy architecture + UX problem. Analysts deserve better than another fickle copilot retrofitted onto a legacy tool designed for manual interaction. They deserve a product that scales to real-world analytics needs,…from shadowfax.ai

Fabi.ai Analyst Agent2025 · fabi.ai · ▲126Hey, I'm Marc one of the co-founders of Fabi! We've all seen the "chat with your data" or the "AI-as-an-assistant" when building reports, but we felt like this wasn't quite right. So we decided to build a system that allowed users to: * Connect any data source to the AI * Purely chat with the AI and their data (so we show the output right in the chat before you even apply the changes) * Convert that chat to a repeatable analysis with a data app or workflow * Toggle back to chat mode without missing a beat Basically this means that if you're a data person, you don't have to go through these…
CamelAI2025 · camelai.com · ▲194camelAI turns your database into an AI data analyst. Ask questions in plain English, get instant reports with visualizations - no SQL required. Why we built this: - Business teams waste hours waiting for data analysts to build dashboards - Non-technical founders can't get quick insights from their own data - Writing SQL queries is a barrier to data-driven decisions What makes it different: - Uses DuckDB to query terabytes in seconds (built-in, no setup needed) - Supports advanced analytics (cohort analysis, statistical computations) not just basic SQL - Multi-turn conversations: AI explores…
PaneJan 2026 · paneapp.com · ▲188Hi HN, I built Pane, a spreadsheet-native agent that operates directly on the grid (cells, formulas, references, ranges) instead of treating spreadsheets as text. Most spreadsheet AI tools fail because they: - hallucinate formulas - lose context across edits - can't reliably modify existing models Pane runs inside the spreadsheet environment and uses the same primitives a human would: selecting cells, editing formulas, inserting ranges, reconciling tables. I launched it on Product Hunt this weekend and it unexpectedly resonated, which made me curious whether this approach actually holds up…
