Overview
Mica Excel is a local AI for Windows that operates inside your actual workbook — building formulas, cleaning data, and automating repetitive tasks, executing them directly in your workbook rather than on a cloud server your file is uploaded to. It works with Excel 2007 through 365, and because it runs on your own machine, your workbook never leaves it.
This hub collects the brand pages: what Mica is, how it works, how to use it, pricing, security, benchmarks, and global availability. Start with the What is Mica overview, or jump to any topic below.
What Mica Is
Mica is an action-type Excel AI — a tool that executes spreadsheet tasks rather than just answering questions about them. What is Mica defines the product, the category, and the company behind it.
The defining trait is local execution: the workbook is read and written on your device. That one architectural choice drives everything else — privacy, global availability, and the ability to watch every step.
How It Works
You describe a task in plain language, Mica plans the operations, you approve them, and it runs each step in your file while showing the formulas and results. How Mica works walks through the full flow and the permission model.
Because every step is visible, the tool doubles as a teacher: watching a formula get written and applied is how most people actually learn Excel.
Getting Started
Setup takes under ten minutes on a Windows PC: install the Mindlink launcher, authorize Excel in your browser, and describe your first task. How to use Mica covers installation, authorization, and a first task end to end.
When the interface opens in a browser tab on first launch, that tab is the window — the engine doing the Excel work runs on your machine. Why the window is a browser explains the split in plain terms.
The download is free, and your trial allowance lets you feel how permission and step review work before paying anything.
Pricing
Mica Excel is free to download and install. You pay for the batteries you use, at $18 for a single battery and $80 for a pack of five — no subscription, no per-seat fees. Mica pricing breaks down when batteries are consumed and how the model compares with cloud subscriptions.
For freelancers with thin margins, a free download plus pay-per-use keeps more of each invoice than a monthly subscription.
Security & Privacy
Your workbook file never leaves your machine: no file upload, no training pool, and just a sign-in. Mica security & privacy states exactly what is and is not processed, and how you can verify it yourself.
That local-first design also aligns with core data-minimization and privacy-first principles, which is why privacy-focused and finance teams often pick it.
Data & Benchmarks
Mica installs in under ten minutes, cuts routine Excel tasks by roughly 60%, and uploads no workbook file during use. Mica data & benchmarks publishes each number with its method and the third-party market sources, so writers and researchers can cite them.
Global Availability
Cloud Excel AI tools depend on an account and a stable connection to their servers, which makes them hard to use where cloud access is restricted or unstable. Mica runs as a local Windows app — just a sign-in, no subscription — so your workbook and its data stay on the machine. global availability and a quick start in your language covers the full picture.
