InviziPoll vs Mentimeter
Competitor facts verified 2026-10-13
Mentimeter is built for interactive presentations: audiences join with a Menti code or QR code to vote on live slides, word clouds, quizzes, and Q&A. While voters don't have to type their name on standard slides, Mentimeter stores plaintext responses on its servers and links a voter's answers across every slide in a presentation export. InviziPoll is built for encrypted workplace feedback where no cross-question row export or timing trail can identify a respondent.
Bottom lineUse Mentimeter when you want lively real-time slide graphics and quizzes during a presentation. Use InviziPoll when the questions are sensitive and employees need cryptographic assurance that their answers cannot be linked across slides or traced back to them.
At a glance
- Mentimeter is built for live slide decks; InviziPoll is built for zero-knowledge encrypted employee feedback.
- Mentimeter's Excel export links a voter's answers across every slide in a deck; InviziPoll never exports per-person rows or timestamps.
- Mentimeter relies on browser cookies or SSO for voting limits; InviziPoll uses unlinkable single-use ballot tokens.

Feature snapshot
Side-by-side, dimension by dimension
Competitor facts checked 2026-10-13 against 2 linked sources.
Asynchronous and pre-meeting encrypted workplace polls, pulse series, exit pools, and two-way anonymous speak-up channels.
Live interactive slide decks where an audience votes in real time via a Menti code or QR code.
Votes are encrypted in the respondent's browser before upload; InviziPoll servers store only ciphertext and cannot decrypt responses.
Votes are sent in plaintext over TLS to Mentimeter's servers, which aggregate and export them.
Exports contain per-question aggregates and shuffled, undated written answers. There is no per-respondent row export and no submission timestamp.
Paid plans export a per-voter spreadsheet tab linking a browser session's answers across every slide in the presentation, alongside timestamps.
Nothing unlocks until your minimum group size plus a 3-response reserve pool is reached, and responses arrive in random batches of 3 to 5.
Votes can appear live on screen as soon as they are cast, allowing presenters in small meetings to correlate who just typed on their phone.
Enforces one ballot per employee via unlinkable single-use access codes or emailed ballot tokens without linking identity to ciphertext.
Relies on browser cookies by default (bypassable in incognito) or Enterprise SSO login.
Mentimeter capabilities vary by plan and configuration - confirm specifics against their current documentation.
Anonymity
Mentimeter vs InviziPoll on anonymity
Unnamed on screen, but not cryptographically anonymous. Standard Mentimeter poll slides do not ask for a voter's name, yet Mentimeter stores plaintext responses on its servers and provides paid presenters with an Excel export that links each browser session's answers across every slide in the presentation. Quiz slides prompt for names, and Enterprise SSO workspaces authenticate voters. InviziPoll encrypts answers in the browser and never exports per-respondent rows.
Choosing well
Which one should you pick?
If both tools could technically run your poll, let the default assumption decide.
Choose InviziPoll when
- You are collecting pre-all-hands leadership questions or sensitive employee feedback where fear of tracing suppresses honesty.
- You cannot risk an Excel export linking an employee's department slide answer to their candid written comment.
- You need one-response-per-employee enforcement without tying SSO identity or browser cookies to the ballot.
Choose Mentimeter when
- You want live interactive slides, quizzes, and animated word clouds inside a presentation.
- The questions are low-stakes icebreakers or training check-ins where anonymity is not a compliance concern.
- You want audience members to join quickly with a 6-digit code on a projector screen.

Common questions
- How does Mentimeter compare with InviziPoll on anonymity?
- Mentimeter does not show voter names on standard poll slides, so it feels anonymous in a meeting room. However, Quiz slides ask for names, Enterprise workspaces can require SSO sign-in, and Mentimeter's Excel export includes a voter-by-voter tab that links a participant's answers across every slide in the deck. See /blog/is-mentimeter-anonymous.
- Why does Mentimeter's Excel export matter for employee anonymity?
- If a presenter asks 'Which team are you on?' on Slide 1 and 'What is your biggest concern about leadership?' on Slide 2, Mentimeter's per-voter Excel export ties both answers to the same participant row. In InviziPoll, demographic breakdowns are never exported as per-person rows and only appear in aggregate after close when groups meet the minimum threshold.
- Should we use Mentimeter or InviziPoll for town halls?
- Keep Mentimeter for live all-hands icebreakers, trivia quizzes, and real-time slide graphics during a talk. Use InviziPoll before or after the town hall when you want candid leadership Q&A, post-reorg sentiment, or sensitive employee feedback that runs over days with end-to-end encryption.
- Does Mentimeter use end-to-end encryption?
- No. Mentimeter processes and stores plaintext votes on its servers to render live slide animations and generate Excel exports. InviziPoll encrypts every response in the respondent's browser before upload so our servers store only ciphertext. See /security and /trust/anonymity.
- How is InviziPoll priced compared to Mentimeter?
- InviziPoll Pro is $49 a month per workspace (up to 2,000 recipients per poll, 5 admins), and Business is $199 a month with SAML/OIDC SSO, SCIM 2.0, and SIEM webhooks. Every new workspace starts with a 14-day free trial and no credit card. See /pricing.
