One session, start to finish

Type nine digits. You’re at their desk.

  1. Connect to another machine: the number 862 471 650 typed in, the password left blank, and the Connect button.
    The helper types the PC's number. With no password, the person there is asked.Real Nelkira 0.6.0 (test build of the release source), the main window, 31 October 2026.
    Step 1

    Type the PC’s nine-digit number.

    The PC you reach shows its number and a password. The person there reads them to you.

  2. The prompt on the far PC: Incoming connection, from a computer on another network, through Nelkira's relay. Allow them? Allow and Reject.
    The request, as the PC being reached shows it. It closes in 60 seconds if nobody answers.Real Nelkira 0.6.0 (test build of the release source), the Allow prompt, 31 October 2026.
    Step 2

    The person there sees the request and chooses Allow.

    With no password typed, the PC asks the person at it. No answer in 60 seconds means no session.

  3. The Nelkira session window: the far PC's desktop filling it, with a Notepad file open and the session bar across the top.
    Working on their screen, in a window on yours. The black box is where their Screen shared sign sits; it is not sent.Real Nelkira 0.6.0 (test build of the release source), the session window, 31 October 2026.
    Step 3

    You work on their screen, in a window on yours.

    Their desktop sits inside your window, with the session bar above it. Several PCs open as tabs.

  4. The helper's Machines tab after the session: 862 471 650, Connected · just now, with Connect and Name it buttons.
    After End, on the helper's side: the PC in the Machines list. The record itself is a file on the PC that was reached (not pictured).Real Nelkira 0.6.0 (test build of the release source), the Machines tab, 31 October 2026.
    Step 4

    End the session. That PC keeps a record of it.

    Who connected, how they got in, when it ended, which files moved. Never the content.

Said plainlyThe record is a plain file on that PC, not tamper-evident yet. What is not done yet.

What you can do in a session

  • View only

    Look without touching their mouse or keyboard.

  • Privacy screen

    Blank their monitor from people walking past.

    Said plainly: it blocks their keyboard and mouse only with administrator rights, or on a PC set up for access when nobody is there.

  • Several screens

    Switch between that PC’s monitors.

  • Copy and paste text and files (Windows)

    In both directions. The record keeps names and sizes, never contents.

  • Ctrl+Alt+Del

    On PCs set up for access when nobody is there.

  • Picture quality: Auto, or choose

    Auto fits the line, or choose Smooth, Balanced or Sharp.

    Said plainly: Auto runs on the PC you reach, so it needs an up-to-date Nelkira there.

  • Several PCs in tabs

    Each PC you reach gets its own tab.

  • Reach a PC from your phone

    Nelkira Go runs in the phone’s browser; nothing to install.

Not yet: chat, a file window.

Where your sessions go

A drawing of one session: you type the PC’s number, the person there is asked and chooses Allow, their screen opens in a window on your PC, and that PC writes the session to its record.Two PCs joined by a line. The left one, yours, shows the number 862 471 650 typed in and a Connect button, then the far desktop with a bar reading Viewing 862 471 650 and the × that ends the session. The right one, the PC you reach, shows the request Incoming connection, Allow them? with Allow and Reject, then the amber Screen shared sign at its bottom right. Under it, the record that PC keeps reads session-started, allowed by the person at this PC, then session-ended.NelkiraYOUR PCConnect to862471650ConnectViewing 862 471 650×directrelay · port 443THE PC YOU REACHIncoming connectionAllow them?AllowRejectScreen sharedThat PC keeps a record of it.session-startedallowed by the person at this PCsession-ended

A session tries the local network and a relay at the same time and keeps whichever answers first. A relay, on port 443, carries sealed bytes it holds no key for.

Said plainlyYou can run your own Nelkira relay. Sign-up, downloads and updates still come from nelkira.com. A session let in with Allow and no password typed is encrypted but not proof against an active attacker in the relay path. What is not done yet.

Four questions

Is it free?

Yes. No card, no trial that expires, no seat count. Paid plans for organisations are planned for 2028; personal use stays free. Pricing.

What does the person at the PC see?

A request to allow you, unless you typed the password the PC shows or your device is remembered there. Then an amber ‘Screen shared’ sign while someone is connected, except on Windows’ lock, sign-in, Ctrl+Alt+Del and administrator-prompt screens. What they see.

Where does my session go?

Direct between the two PCs where the network allows; otherwise through a relay on port 443. A relay holds no key that would let it read a session. Security.

What is not done yet?

No certification is claimed, the installer is not code-signed, the record is not tamper-evident, and chat and a file window are not built. The full list.
