What screen sharing software is (and is not)
Screen sharing software lets someone on a call show their screen to everyone else, in real time, so the group looks at the same spreadsheet, slide, or bug instead of hearing it described out loud. That sounds like a solved problem because every laptop can do a basic version of it, but the gap between "mirrors a screen" and "actually useful in a work call" is bigger than it looks.
Key takeaways
- Screen sharing software is more than the "share screen" button inside a video call. The versions worth paying for add annotation, control over who can share and who can see it, and a record of what was shown.
- The real risk is not encryption. It is a share that goes to the wrong meeting, or a guest who can draw on your screen without asking first.
- Standalone screen-share and annotation add-ons often run alongside a video tool as a separate line item. Check whether that layer is already included before you pay for it twice.
It is not remote desktop software. Remote desktop tools hand over control, so the other person can move your mouse and type on your keyboard. Screen sharing is view-only: people see what is on your screen, but nobody else is driving.
It is also not screen recording. Recording captures a screen for later. Screen sharing broadcasts it live to people who are on the call right now. The two often ship in the same product, but they solve different moments: one is for the call happening today, the other is for whoever could not make it.
What it should actually do
A basic screen share is table stakes on almost any video tool. What separates software worth relying on is what happens once the screen is up.
Annotation and drawing tools
Annotation lets other people mark up what is on screen: circle a line of code, underline a number on a spreadsheet, point at a spot on a design mock-up without saying "no, the other one, up and to the left a bit." It turns a one-way broadcast into something the whole group is actually working on together.
Access and permission controls
Who can start sharing, and who can see it once it starts, matters more than most teams think about until it goes wrong. A support call should not default to letting every guest share their screen. A sales demo should not let a competitor sitting in on the call take over the presentation. Good screen sharing software makes both a setting, not an accident.
Multiple screens at once
A design review or a pair-programming session often needs two people showing something side by side, not one screen and a queue. Tools built for real work support more than one active share, so the group can compare two versions instead of switching back and forth.
| Feature | What it does | Why it matters |
|---|---|---|
| Annotation | Lets others draw or point on the shared screen | Turns a broadcast into a working session |
| Share permissions | Controls who can start and stop a share | Stops the wrong person taking over a call |
| Multi-share | Shows more than one screen at once | Useful for reviews and side-by-side comparisons |
| Recording handoff | Saves the shared screen with the rest of the call | Nobody has to re-explain what was shown after the fact |
Where teams actually use it
Screen sharing shows up in more parts of a mid-market or enterprise workday than most people notice, because it replaces a description with a demonstration.
- Sales demos. Walking a prospect through a product live closes more gaps than a slide deck ever will, and it is the moment a bad connection or a clunky share button costs the most.
- Support troubleshooting. Talking someone through a setting they cannot find is slow. Watching their screen and pointing at the exact button is fast, especially with annotation switched on.
- Design and code review. Two screens side by side, with both people able to point and mark up, turns feedback into something concrete instead of a comment thread nobody reads in order.
- All-hands and training. One person presents to a large group, often recorded for people in other time zones, which is a different scale problem than a five-person call.
The question most teams skip
When teams evaluate screen sharing, most of the questions are about video quality and lag. The bigger risk is quieter than that: what gets shown, to whom, and what happens to it afterward.
A sales rep sharing their whole desktop instead of one window can expose a Slack notification with a customer complaint, an email draft, or a pricing sheet meant for a different account. A support agent letting a guest share back can hand a stranger a window into an internal tool. None of that is a bug in the software. It is a default that was set too loose.
The fix is mostly about defaults, not features: share one window instead of the full screen where possible, require the host to approve who else can share, and use a blurred or custom background so whatever is behind the call window on a video feed does not become part of the demo by accident. Teams that set these once, rather than trusting everyone to remember on every call, have far fewer awkward moments.
What to check before you buy
Most video tools can mirror a screen. The differences that matter for a growing team show up in the details.
- Can more than one person share at the same time? If reviews and pair sessions are common, a single-share limit gets in the way fast.
- Does annotation work for guests, not just the host? A customer or contractor on the call should be able to point at something without needing an account.
- Can you control who is allowed to share by default? Open-to-everyone should be a choice, not the only option.
- Does the shared screen get saved with the recording? A recap that skips what was actually on screen during the important part of the call is not much of a recap.
- Is it billed as a separate add-on? Some vendors meter screen sharing or annotation as a paid extra on top of a video plan. Check the line item before you sign.
How WeldMeet handles it
WeldMeet is the video meetings product built into WeldSuite. Screen share and annotation are built in on every call, along with custom and blurred backgrounds, so what is behind you does not end up part of the demo. Calls support up to 1,000 participants and can run up to 24 hours, which covers everything from a two-person design review to a company-wide training session.
Every call auto-records with a full transcript, and the recording, including whatever was shared on screen, lands directly in WeldCalendar next to the event that created it. Because WeldMeet sits on the same shared record as WeldCRM and WeldDesk, a screen-share demo on a sales call or a support session can update the deal or the ticket it belongs to, without anyone re-explaining what was on screen after the fact.
WeldMeet is one of the twelve apps included in every WeldSuite tier, not sold as a metered add-on: free for a single seat, $49 a month on Business for teams up to 10 seats, $69 a month on Scale with no seat cap, and custom pricing on Enterprise with SSO, SAML, and data residency. Screen sharing and annotation are not a separate line item at any tier.

Frequently asked questions
What is screen sharing software?
Screen sharing software lets someone on a call show their screen to everyone else in real time. The useful versions add annotation so others can mark up what is shown, controls over who is allowed to share, and a recording that keeps the shared screen alongside the rest of the call.
Is screen sharing software the same as remote desktop software?
No. Screen sharing is view-only: people see your screen but cannot control it. Remote desktop software hands over control, so the other person can move the mouse and type. They solve different problems and are usually separate tools.
Can more than one person share their screen at the same time?
On some tools, yes. It matters most for design reviews, code review, and any session where two things need to be compared side by side rather than shown one after another.
Is screen sharing secure enough for sales demos and support calls?
It can be, but the risk is usually a loose default rather than the software itself. Share one window instead of the full desktop, control who is allowed to share, and use a blurred background so nothing behind the call window ends up on screen by accident.
What does screen sharing software cost?
Some vendors meter screen sharing or annotation as a separate add-on on top of a video conferencing plan. WeldMeet includes both in every WeldSuite tier, from a free single seat through Business at $49 a month and Scale at $69 a month, with no extra charge for the feature.
