ARC Tasks Kanban board and a Söyleşi group chat — SORA Aviation sample workspace

One workspace, three sections.

ARC's menu splits work into three sections. Every app runs on the same company, people and permission records, so work started in one shows up in the others.

Guests and a waiting room: People from outside your company wait for the host to let them in.
Recording, transcript, summary: Recordings are transcribed and summarised; the summary can be edited.
Agenda and decisions: Items, decisions and PDF minutes; open tasks straight from the meeting.
Screen sharing: Raised hands, reactions, background blur and in-meeting chat.

Divit desktop with a maintenance procedure: headings, a numbered list and a responsibilities table

Matris Spreadsheet

Numbers, as they are.

Matris opens .xlsx workbooks, keeps formulas and formatting, and exports to PDF when you need it. A gallery of 29 formulas, with Turkish and English names, drops into the cell in one click.

Formula gallery: SUM, VLOOKUP, IF and 26 more, in Turkish or English.
Data dashboard: A chart and a pie chart from the selected table.
Data from the web: Pull JSON from a URL into the sheet.
Export to PDF: Turn a workbook into a document you can share.

When the connection drops, work doesn't.

Taking a document from Sandık cloud to your computer locks it first, so nobody overwrites it while you work. When you're back, it returns as a new version. Sandık comes with the ARC Office package and business accounts.

Lock and take
The document is locked and downloaded, encrypted, to your computer. The lock stays with you.
Work offline
Saves go to the local vault first. Without a connection they queue, and the app still opens.
Return as a new version
Once you're online the change goes to Sandık as a new version. If there's a conflict nothing is overwritten: your copy is kept as a separate document.

Local copies are encrypted to your Windows account.
Documents marked “top secret” can't be taken offline.
Your password never enters the app; you sign in through the browser.

Sandık

Every version, kept.

Sandık stores your documents in folders, with their versions. Every save is a new version, and you can go back to any earlier one. Divit and Matris open documents in Sandık directly.

The installer isn't code-signed yet. If Windows shows “Windows protected your PC”, choose “More info” and “Run anyway”; the file's hash should match the one above.

You can verify the downloaded file's hash in PowerShell: Get-FileHash .\ArcOffice-Divit-Setup-*.exe

Create a free account.

Divit and Matris are free; the account is used by app versions that ask you to sign in. After signing up, confirm your address with the link we email you. Sandık cloud and the AI features planned for later are part of the paid package.

For your whole company.

ARC Office is part of ARC, the digital workspace of the BilTAY NexUS platform. If your company uses NexUS, choose business sign-in in the same apps: documents live in your company's Sandık, and sharing and permissions stay with your administrator.
