Chat overlay vs moderated Q&A: StreamYard and Restream comments or a curated question queue?
Richard Frantzen, founder of AskTide · Updated
Putting viewer comments on screen and putting audience questions on screen sound like the same thing. They aren't. This comparison looks at StreamYard's on-screen comments and Restream's chat overlay next to a moderated Q&A overlay, and explains when each is the right tool and when to use both.
Short answer: A chat overlay (StreamYard's Chat Overlay, Restream's chat embed) shows comments from connected streaming platforms, so it suits creator and community streams. A moderated Q&A overlay shows one question a producer chose, from an audience page anyone can open without a platform account, so it suits interviews, town halls and events with an in-room audience. Many shows use both.
The short answer
Use a chat overlay when the conversation is the content: a gaming stream, a creator Q&A on YouTube, a live launch where you want viewers to see themselves on screen. Use a moderated Q&A overlay when the question is the content: a panel, an all-hands, a council meeting, a hybrid event with people in the room. The difference is who decides what reaches the screen and who is able to ask in the first place.
| Chat overlay | Moderated Q&A overlay | |
|---|---|---|
| Where questions come from | Comments on connected platforms (YouTube, Twitch, Facebook…) | A dedicated audience page, by link or QR code |
| Who can ask | Viewers with an account on that platform | Anyone with the link, including the room |
| What reaches the screen | A stream of messages, or one featured comment | One question at a time, chosen by a producer |
| Editing before air | Not described | Typically yes (fix typos, shorten) |
| Works with no social destination | No | Yes |
| Best for | Community energy, creator streams | Interviews, panels, town halls, hybrid events |
How StreamYard shows comments on screen
StreamYard gives you two ways to put viewer comments on screen. You can feature an individual comment manually, and its Chat Overlay automatically displays incoming comments from supported platforms. Supported platforms are YouTube, LinkedIn, Twitch and Facebook Pages and Profiles; Facebook Groups and Instagram are not supported. Only comments from connected destinations appear, in chronological order.
Chat Overlay is a paid feature. StreamYard's help article says it is available on all paid plans, while the pricing page first lists it on the Core plan, so check the plan you're on. The free plan also puts the StreamYard logo on the stream.
StreamYard's own guide to streaming Q&A sessions describes the manual flow, where you or a producer select a question and show it on screen, and suggests a Streamlabs chat overlay as a browser source for OBS users. Its overlay guide treats overlays in StreamYard as uploaded graphics such as transparent PNGs, and points people who need browser widgets to tools like OBS (StreamYard blog).
StreamYard comment featuring is a good, simple tool. Its limit is the source: if a person isn't commenting on a connected platform, their question can't be featured.
How the Restream chat overlay works in OBS
Restream's chat embed for OBS is added as a browser source. You can show chat from all platforms, Twitch only, or a specific event, and set theme, alignment, opacity, size and auto-hide. That makes it a tidy way to show a combined chat feed when you multistream.
What the article doesn't describe is picking individual messages to show, holding messages back for review, or editing them. It also doesn't say which plans include the embed; Restream's pricing lists a free plan with 2 channels and Restream branding, plus paid plans. So if you search for how to pick one comment to show in OBS, the Restream chat embed as documented is the wrong tool: it is a chat stream, not a curated queue.
What a moderated Q&A overlay does differently
A moderated Q&A tool separates three things that chat overlays merge: collecting questions, choosing them, and showing them. Questions arrive on an audience page. A moderator reviews and shortlists. A producer puts one question on air, and only that question reaches the graphic.
In AskTide, for example, the audience opens a link or scans a QR code, types a question (name optional) and needs no app or account. Questions move through New, Selected, On Air and Done; the operator can edit a question before air or add one manually, for instance a question that came in by email. Only one question is on air at a time. The Display output is a transparent 1920×1080 browser source for OBS, vMix or TriCaster that styles the question as a card, lower third, ticker, minimal text or full screen. AskTide does not import YouTube or Twitch chat, and it has no audience upvoting; both are outside its design.
Other moderated Q&A tools exist, with different trade-offs, such as Q&A Events and QuestionWall. See best Q&A tools for live streaming for the full comparison.

(checked November 2026) StreamYard and Restream facts are from the help articles linked above. "Not described" means the documentation doesn't mention it, not that it's impossible.
When a chat overlay is the right choice
- Creator and gaming streams, where seeing chat on screen is part of the fun and speed beats curation.
- Your whole audience is already on one platform, for example a YouTube-only show with an active comment section.
- You stream from StreamYard and want zero extra tools: feature a comment with one click, or turn on Chat Overlay on a paid plan.
- You multistream and want one combined chat feed in OBS: the Restream chat embed does that.
- Low stakes: a comment that slips through is not a problem for your brand or your organization.
When a curated Q&A is the right choice
- Interviews and panels, where the host needs a clean, well-phrased question at the right moment.
- Town halls and all-hands, where questions should be reviewed before anyone sees them. See the town hall Q&A checklist.
- Public-sector broadcasts such as council meetings, where an editor must decide what goes on air and nobody should need a social account to take part.
- Internal streams with no social destination, for example a private stream for staff. A chat overlay has nothing to read from; a Q&A page works anyway.
- Hybrid events, where people in the room and online should ask through the same channel. See hybrid event Q&A.
- Branded productions, where the question graphic has to match your lower thirds and template.
Privacy: in-room audiences without platform accounts
A chat overlay only works for people who comment on a platform, which means they ask under a platform identity and their comment lives in that platform's public chat. For a staff meeting, a school event or a council meeting, that's often the wrong default: some people don't have an account, some don't want their name attached, and some questions shouldn't be public until a moderator has looked at them.
A dedicated Q&A page lowers that bar. In AskTide the audience needs no app and no account, the name is optional, and the operator decides whether the submitter's name appears on the graphic. Questions are reviewed in the manage or moderator view before anything is shown. There is no automatic profanity filter, so that human review is the safeguard. The link also accepts questions any time, so you can open it days before a meeting and collect questions in advance. For a practical workflow, read how to moderate a live Q&A.
Show the audience link as a QR code on screen and in the room so people don't need to type a URL.
Can you combine a chat overlay and a moderated Q&A?
Yes, and many shows should. The chat overlay keeps the stream feeling alive; the moderated Q&A carries the questions that matter. In OBS or vMix, both are just layers.
- Add both as sources. In OBS, add the Restream chat embed and your Q&A output as separate browser sources (see the OBS Studio guide). In vMix, use Web Browser inputs (see the vMix guide).
- Give them different screen areas. Keep chat in a side column or auto-hide it, and reserve the lower third or center for the on-air question so they never overlap.
- Route good chat questions into the queue. When a strong question appears in chat, the moderator adds it to the Q&A queue manually, cleans it up and shortlists it. In AskTide the operator can add and edit questions by hand.
- Pick a scene per segment. Use a scene with chat for open discussion and a scene with the Q&A graphic for the formal question round.
If your show runs in StreamYard rather than OBS or vMix, note that StreamYard's overlays are uploaded graphics and its own blog points users who need browser widgets to tools like OBS. In that case, a common pattern is to produce in OBS or vMix and send the program to your platforms from there.
Frequently asked questions
How do I show comments on screen in StreamYard?
Feature a comment manually, or turn on Chat Overlay, which automatically displays comments from connected platforms. Chat Overlay is a paid feature, and only YouTube, LinkedIn, Twitch and Facebook Pages and Profiles are supported.
Can I pick one comment to show with the Restream chat overlay?
Restream's OBS chat embed documentation doesn't describe picking individual messages; it shows a chat feed with options for theme, alignment, opacity, size and auto-hide. For single, curated questions, use a moderated Q&A tool.
How can viewers ask questions without YouTube chat?
Use a Q&A tool with its own audience page. With AskTide, viewers open a link or scan a QR code and type a question with no app or account.
Is a chat overlay or a moderated Q&A better for a town hall?
A moderated Q&A is usually better, because questions are reviewed before they are shown and people can ask without a platform account. A chat overlay suits community streams where speed matters more than curation.
What is a good StreamYard chat overlay alternative?
If you want curated questions rather than a chat feed, a moderated Q&A tool with a browser source, used in OBS or vMix, is the alternative. If you only need a chat feed in OBS, Restream's chat embed works as a browser source.
Can I use a chat overlay and a Q&A overlay at the same time?
Yes. In OBS or vMix, add both as browser sources in separate screen areas, and have the moderator copy strong chat questions into the Q&A queue.
