Show HN: TabTabTab – Cursor for Google Sheets

Hello, HN!

We are Gyani and Vasin. We’re building TabTabTab (https://tabtabtab.ai), an AI agent that helps you work faster in Google Sheets. Before this we worked at Bloomberg (where we met 7 years ago), Citadel, and Palantir.

We’re software engineers, and it feels fundamentally unfair that the best AI tools are limited to software engineers. Most knowledge workers only have ChatGPT as the best option. We want to give everyone AI superpowers.

A few months ago, we started by putting AI into copy and paste. Our assistant was aware of what you copied, and transformed it as you pasted it. We built this on accessibility and screenshot APIs. The goal was to move away from the chat box by building on one of the most-used shortcuts: copy and paste.

We noticed most users were using it to structure data in Google Sheets. They would copy from places like LinkedIn, PostHog, booking sites, business directories, and conference websites, then structure it in Sheets.

We decided to narrow in on this. We can deliver far more value if the interaction doesn’t end at paste. Much of what people do with copy and paste can be handled by an agent using web search, crawling, and data providers. And once the data is in the sheet, people want to do something with it—so we help with that too.

That’s how TabTabTab for Google Sheets was born. It’s a Chrome extension that lets you interact with a copilot that understands Google Sheets, can run code, has access to web search and enrichment APIs, and can crawl the web (we can do this on our backend or locally on your computer if you grant extra permissions).

While it’s very early, we’ve seen some interesting use cases:

- One of our first paying customers (a complete stranger) is a bank manager in Laos who also runs cafes on the side. He used TabTabTab to model the business, launch the main shop and five additional locations, and now uses it to manage the operation.

- Many people use us for enrichment. We ship with search plus some APIs, so if you have a list of LinkedIn URLs and want to figure out who they are, we can do that for you.

- We’ve seen data analysis use cases like customer segmentation, sensitivity analysis, categorizing and ranking data, and teachers building course schedules and staff allocations.

This seems to resonate with generalists and SMB professionals. Often they’re very comfortable with Google Sheets and don’t want to learn a new tool for a specific job, or there simply isn’t a tool for their use case—so they pick Google Sheets, and now us.

Permissions: You sign in with your Google account. We can only see files you explicitly grant access to, individually. Our Chrome permissions are standard. Optionally, we can request permission to open websites on your behalf (for example, if you’re trying to find mutual connections with someone on LinkedIn).

Pricing: Free Pro trial for 7 days, then $20/month for Pro, which includes access to Claude 4 Sonnet, GPT-5, and Gemini 2.5 Pro. There’s also a free tier with generous limits on more basic models.
