Inventory starts with one person.

Tana has been available since 2018. Since the beginning, 99% of users have started managing inventory on their own. That pattern appears in homes and in organizations with hundreds of people. Before there is a shared process, there is usually someone willing to count what is left and keep a record.

We design for that first step. You should be able to choose a tool because it helps with the work in front of you. A useful inventory habit can begin at one shelf, without waiting for everyone else to change how they work.

Pick a few supplies you use regularly. Add them to Tana, record how much you have, and take a photo so they are easy to recognize later. On supported devices, Apple Intelligence can generate an image when you would rather skip the photography. A barcode scan helps you find the item again and update its stock where you use it.

Set a stock alert before those supplies reach zero. The point of keeping a count is to have time to act: replace the cleaning supplies, order another reagent, or refill the cupboard before somebody needs the last item. A small, useful list is a good place to start.

At home, that list might contain cosmetics, supplements, and protein powder. A café might track milk, syrup, napkins, and the cups that need replacing when they break. A clinic has different supplies, such as test kits, specimen tubes, needles, and gauze, but the everyday question is familiar: what is left?

Equipment belongs in the picture too. A photographer can keep lens-cleaning supplies alongside cameras and batteries. A film crew can track tripods, monitors, and Arca-Swiss-compatible adapters. Tana gives those items a place in the same inventory instead of leaving them in somebody’s memory.

Tana began with 50 students working across three rooms. Thousands of chemicals and shelves full of reagents were used day and night. Running out could mean waiting a week for a delivery. A spreadsheet was no longer enough to keep up with what was happening at the shelves.

We built Tana for that environment, and it still guides our decisions. A feature should make sense when someone needs it in a busy laboratory at two in the morning. The aim is to make keeping records part of the work, rather than another job to finish afterwards.

As the habit takes hold, a handful of items can become hundreds or tens of thousands. Tana keeps the work on your phone, while cloud synchronization lets you invite other people when managing everything alone becomes too much.

You can also connect AI agents such as ChatGPT, Claude, and Gemini through Tana’s MCP server. Start with the inventory you need today; add collaborators and AI tools when they become useful to the way you work.

An inventory can look like a simple list, but it holds information your work depends on. Tana stores that data in a managed cloud database with three layers of backup, and communications use modern encryption.

You do not need to organize every room before beginning. Choose the supplies you most want to stop running out of, give them a place in Tana, and build from there.
