Slido vs Poll Everywhere — and a Pay-Per-Use Third Option for Occasional Events
Search "Slido vs Poll Everywhere" and every result reaches the same verdict: both are capable, both do live polls and Q&A, pick whichever your team already uses. That is true and useless. The honest split is sharper than the feature matrix suggests — **Slido is built around moderated Q&A and town halls, Poll Everywhere around polls embedded in slide decks and the classroom** — and the thing that actually decides most purchases is neither feature: it is the pricing model and the participant cap. This article compares the two on what they are each best at, what they cost, how their limits work, and how they moderate anonymous posts on the live screen — then covers the flat pay-per-use option that fits a few events a year better than either subscription.
- Poll Everywhere is the stronger pick for polls embedded in PowerPoint / Google Slides and for classrooms with LMS integration
- Both have free tiers with hard caps (Slido: 3 polls and 100 participants per event; Poll Everywhere: 40 responses per poll) and both push annual subscriptions in the default comparison
- Both also sell one-time event plans — so "you must subscribe" is a myth — but each is priced by participant tier (200 / 1,000 / 5,000), which is easy to miss and scales with room size
- ZENIN CLOUD is a flat pay-per-use third option: $70 for 7 days ($10/day), no contract, no plan-based participant cap, AI moderation of posts, QR-only join, and CSV export — built for the occasional event, not the weekly meeting
Slido vs Poll Everywhere vs a pay-per-use tool
Slido vs Poll Everywhere: the short answer
Both tools do live polls, word clouds, Q&A and quizzes competently, so the feature-by-feature verdict is close enough to be a coin toss. What separates them is emphasis. Slido is built around moderated Q&A — the upvote queue, question filtering, and tight WebEx / Cisco Webex and Microsoft Teams integration make it the natural fit for company all-hands and conference Q&A. Poll Everywhere is built around polling inside a slide deck, with strong PowerPoint and Google Slides embedding and LMS integration for the classroom.
So the quick rule: if your event is a town hall or a conference where taking and ranking audience questions is the point, lean Slido; if it is a lecture or a presentation where polls live inside your slides, lean Poll Everywhere. But before you pick either, notice what both comparisons quietly assume — an annual subscription. For a few events a year, the pricing model matters more than the Q&A-vs-slides distinction, which is why this article ends with a flat pay-per-use option instead of a second subscription.
Live polls, word clouds, Q&A and quizzes are table stakes — Slido, Poll Everywhere, Mentimeter, AhaSlides and the rest all do them. Choosing on the feature matrix is why the comparison stalls. The axes that actually differ are the billing model, the participant cap, and how each tool handles an abusive anonymous post on the projected screen.
What each tool is built for
The clearest way to choose is to match the tool to your event shape rather than to a checklist.
Slido — moderated Q&A and town halls
Slido's centre of gravity is the Q&A queue: the audience submits questions anonymously, everyone upvotes, and a moderator promotes or hides them. That workflow is why it dominates enterprise town halls and conference sessions, and its integrations follow the same audience — WebEx and Teams first, with a slide add-in for PowerPoint and Google Slides. If your recurring problem is "we get the same three vocal people and never surface what the room actually wants to ask", Slido is designed for exactly that.
Poll Everywhere — slide-native polling and the classroom
Poll Everywhere leans the other way. Its polls, word clouds and competitions embed directly into a slide deck, and it carries deeper education features — LMS integration, gradebooks and attendance — that make it a fixture in universities. It offers a broader spread of question types for assessment and live feedback, but its open Q&A moderation is generally rated less developed than Slido's. If you present from slides most weeks and want interaction without leaving the deck, Poll Everywhere is the more natural home.
Pricing and participant limits compared
This is the axis that decides most purchases, and it is where the two tools look more alike than different: a capped free tier, annual paid plans, and — the part most comparisons skip — one-time event plans priced by audience size.
Slido. The free Basic plan allows 3 polls and up to 100 participants per event, with unlimited Q&A. Paid tiers (Professional, Enterprise) are billed annually, and Slido also sells one-time event plans that cover a single event for up to 7 days with unlimited polls and quizzes — starting around $60 for up to 200 participants and scaling by tier to 1,000 and 5,000 (Slido — Pricing).
Poll Everywhere. The free plan caps an activity at 40 responses (Poll Everywhere — Audience Size Limits); paid non-education plans cap at 700 responses per poll, with larger rooms pointed to Enterprise. Its standard business tiers are billed annually (Poll Everywhere — Plans), and it publishes separate event-based pricing for one-off conferences (Poll Everywhere — Events pricing).
The takeaway: neither tool "forces" a subscription — both have one-time options. But both price those options by participant tier, so a big room costs more, and the tier you need is easy to under-buy. Check your largest session against the cap of the plan you would actually purchase before you compare anything else.
Features and question types
Feature parity is real, but the edges differ. Both do live polls, word clouds, quizzes, open text and Q&A. Slido's standout is the moderated, upvoted Q&A and its quiz leaderboard for lighter sessions. Poll Everywhere's standout is the range of poll types and the depth of slide embedding, plus classroom-specific tools like grading and attendance.
For a live word cloud specifically — the format where the whole room types a word and it appears on screen instantly — both tools render one well. The difference shows up not in the visual but in what happens when someone types something abusive, which the next section covers. If you want the practical craft of running one, how to run a live word cloud walks through the prompts that actually get responses.
Integrations and how the audience joins
Integrations are where each tool's DNA shows. Slido integrates most deeply with WebEx and Microsoft Teams, with slide add-ins for PowerPoint and Google Slides. Poll Everywhere embeds natively in PowerPoint, Keynote and Google Slides and connects to major LMS platforms — the reason it is entrenched in education. Match this to your stack: a Teams-first company and a Slides-first lecturer will each feel the pull toward a different tool.
On the audience side, both are browser-based with no app to install. Participants reach Slido by a join link or an event code, and Poll Everywhere by a web link, a code, or text message. The small friction is the code: reading a numeric code aloud to a large room reliably produces a wave of "I can't get in" as people mistype it. A QR code projected on the screen removes that step — worth checking how each option handles the first two minutes of a big session, because that is where a large audience usually stalls.
Moderating anonymous posts on the live screen
This is the operational difference that never appears in a feature matrix and matters most the moment it goes wrong. Anonymous input invites the occasional abusive post, and a live word cloud or open Q&A puts it in front of the whole room instantly.
Slido and Poll Everywhere both rely on the same basic mechanism: a keyword or profanity filter plus a moderator who approves items before they display. That works, and Slido's moderation queue in particular is well built for Q&A. But a word-list filter has a structural weakness — it cannot keep up with deliberate misspellings, spacing tricks or coded phrasing, so someone determined to get past it usually can, and the filtered result still needs a human watching the screen.
Word-list filters match strings. Attackers change strings — swap a letter, add a space, use a homophone — faster than any list is maintained. That is not a flaw in one product; it is the ceiling of the list approach, and it is why "we turned the filter on" is not the same as "the screen is safe".
ZENIN CLOUD takes a different approach: an AI classifier judges each post by meaning rather than matching a list, so it does not depend on the list being current and holds up better against deliberate misspellings — including in Japanese, where kana and substitute characters make list-matching especially brittle. You should still keep one person watching the projected screen with any tool, but the starting point is stronger when the filter reasons about intent instead of spelling.
The pay-per-use third option: when a flat price wins
The Slido-vs-Poll-Everywhere question quietly assumes you are buying a subscription. For a team that runs live sessions most weeks, that assumption is right, and this section is not aimed at you — the template library and the muscle memory of weekly use are advantages a per-day tool cannot match. But for the far larger group running a handful of events a year, both subscriptions bill through the idle months, and even the one-time plans scale their price with the size of the room.
A flat pay-per-use tool changes the maths. ZENIN CLOUD is $70 for 7 days ($10/day), card checkout only, with no contract or cancellation, no plan-based participant cap (it handles hundreds to thousands), AI moderation of posts, QR-only join, and CSV export on every plan. Count the days you actually ran a live session last year — not the days you meant to — and drop them into a break-even.
The pattern is the same as any subscription: below a certain frequency, per-day pricing is far cheaper; above it, the subscription pulls ahead. For a few events a year the gap is large — and you avoid choosing between Slido's Q&A and Poll Everywhere's slide polls when what you really needed was one interactive session, run once, without a renewal. The pay-per-use case against Slido and the Poll Everywhere alternatives comparison go deeper on each.
How to choose in one sitting
Spreadsheet comparisons stall because both tools check every box. Four questions settle it faster than any feature grid.
Moderated Q&A / town hall → Slido. Polls inside your slides / classroom → Poll Everywhere. One-off interactive session → price pay-per-use.
Days you actually ran a live session. A few, price per-day; most weeks, a subscription earns its keep.
Take your largest session, add 30% for people joining from two devices, and see which participant tier — 100, 200, 700, 1,000 — still covers it.
Post something borderline during a test and watch how each tool handles it on the projected screen. That moment defines the event.
ZENIN CLOUD is $70 for 7 days ($10/day), card checkout only, with no contract, no plan-based participant cap, QR-only join and CSV export. If a single interactive session — not a year of them — is what you are buying, it is the option the Slido-vs-Poll-Everywhere comparison leaves out.
Which decision are you actually making?
If two or more of these are true, price a pay-per-use tool before renewing either subscription.
Frequently asked questions
Is Slido or Poll Everywhere better?
Neither is better overall; they specialise differently. Slido is stronger for moderated, upvoted Q&A and town halls, with deep WebEx and Microsoft Teams integration. Poll Everywhere is stronger for polls embedded in PowerPoint or Google Slides and for classrooms with LMS integration. Choose by event shape: Q&A-led session → Slido; slide-embedded polling or teaching → Poll Everywhere.
What is the difference between Slido and Poll Everywhere pricing?
Both have capped free tiers (Slido: 3 polls and 100 participants per event; Poll Everywhere: 40 responses per poll) and annual paid plans. Both also sell one-time event plans, but each is priced by participant tier, so a larger room costs more. If you only run a few events a year, a flat pay-per-use tool such as ZENIN CLOUD ($70 for 7 days, $10/day) avoids both the annual commitment and the tiered per-event pricing.
Which is better for a town hall or all-hands meeting?
Slido, in most cases. Its moderated Q&A with upvoting and question filtering is built for exactly that format, and its WebEx and Teams integration fits enterprise all-hands. Poll Everywhere works too, but its open Q&A moderation is generally rated less developed. If the meeting is large and one-off, also price a pay-per-use tool with no plan-based participant cap.
Does Slido or Poll Everywhere have a free plan?
Both do, with hard caps. Slido Basic allows 3 polls and up to 100 participants per event with unlimited Q&A. Poll Everywhere’s free plan accepts up to 40 responses per activity — later responses are simply not counted. Free tiers are good for evaluating the interface; a real event with a large audience will need a paid plan on either tool.
Do I have to buy an annual subscription for a single event?
No. Both tools sell one-time event plans in addition to annual subscriptions, so "you must subscribe" is a myth — though the event plans are priced by participant tier and easy to miss in a standard comparison. For a truly occasional event, a flat pay-per-use tool charges one price for the days you use ($70 for 7 days) with no participant tier and no renewal.
How do the two tools handle abusive anonymous posts?
Both use a keyword or profanity filter plus a moderator who approves posts before they appear. That works but cannot keep up with deliberate misspellings, and it needs someone watching the screen. An AI classifier that judges posts by meaning rather than matching a word list — as ZENIN CLOUD uses — holds up better against evasion, especially in languages like Japanese; you should still keep one moderator on the projected screen with any tool.
