Anonymous question services compared: Marshmallow, Peing (Aug 2026)

Before you read this comparison

There are several anonymous question box services, and each one is built around a different idea. In this article, we sort out the differences between the main services based only on what we could confirm on each service's official pages and official help as of August 2026. For items we couldn't find in official sources (such as prices), we don't guess; we mark them as "not stated."

This site is written by the Q drop team, the people who run the question box service "Q drop," so we want to make that clear up front. With that in mind, we compare the services on the facts, including the strengths of other services, and organized the article so you can decide which one fits your own purpose.

Note that BoxFresh, which was once widely used, is not included in the comparison. At the time of writing, visiting its official site (boxfresh.site) still didn't show the actual service page, so we couldn't confirm how it works.

Overview of the main services (from their official pages)

Peing (also known as Shitsumonbako, "question box"). A long-standing service launched in 2017, with the slogan "collect anonymous questions using social media." Its official page says you can create "a question box in 5 seconds" and that when you answer a question, you can share it to your social media timeline with an image. For dealing with abuse, it has an "NG word (banned word) feature," which the official page describes as being able to "automatically block questions that contain abusive expressions (more than 10,000 questions are automatically blocked every day)." The page also clearly states that Instagram sign-in is no longer offered.

Marshmallow. Its catchphrase is "we want fewer people to get hurt," and its official page describes it as "a safe place where you can receive anonymous messages without getting insults." Its headline feature is a design that spares you from receiving negative content, and it's widely used by creators as a place to collect feedback on their work. Besides messages addressed to you, it has features called "messages to everyone" and "answer requests," and there is also a paid premium membership (the price isn't listed on the official top page, so we don't give it here). Along with Japanese, it supports multiple languages including English, Chinese (Simplified and Traditional), and Korean.

Querie.me. A service with the slogan "a question box that sparks new ideas," available as iOS and Android apps and as a PC (browser) version. The official top page has few detailed descriptions of its features, so this is as much as we can say in this article.

mond. A service its official site describes as "anonymous letters & Q&A," available as iOS and Android apps.

Q drop (this site). A free web service that lets you create a question box with just an email address. It uses magic link sign-in with no password, and there's no app to install. It has measures to deter unwanted and inappropriate posts, and questions you receive are deleted automatically after 90 days.

Point 1: How you sign up and how much effort it takes to start

If you're opening a question box to receive questions, the first hurdle is how you sign up.

Peing guides you to sign in with a social media account or similar (Instagram sign-in is no longer offered). It's a quick option if you want to use your existing social media account as is.

Marshmallow and Querie.me have their own sign-up and login systems. For Querie.me, installing the app is the main way in, and for mond, the entry point shown on the official page is also the store links for its iOS and Android apps. Apps make it easier to get notifications, but installing one is an extra step.

Q drop lets you sign up with just an email address, with no password to set and no need to link a social media account. It suits people who don't want to link their social accounts or who want to casually use it with a secondary account. On the other hand, it doesn't have features like automatic sharing through linked social accounts, so you need to share it yourself.

Point 2: How each service approaches abuse and trolls

When you accept questions anonymously, being prepared for cruel messages is the most important point when choosing a service. From each service's official explanations, you can see differences in the thinking behind their protections.

Peing uses an NG word approach. Its official page states that it automatically blocks questions that contain abusive expressions.

Marshmallow's selling point is a design where "insults don't come." It aims to keep negative content from arriving in the first place, an approach that fits well if you want to feel safe receiving feedback and messages of support.

Q drop has measures against inappropriate posts and also a system that deters automated repeat posting. In addition, the owner of a question box can see the sender's IP address, which helps when deciding whether to block someone malicious.

One caution applies to every approach: automatic filters aren't perfect. Whichever service you choose, we recommend checking where the block feature is and how to report someone right at the start.

Point 3: What "anonymous" means differs by service

This is easy to overlook, but it's the most important difference. Even though they're all called "anonymous question boxes," how hidden the sender is varies from service to service.

Peing's official page explains its system for followers sending questions by saying, "Since it's anonymous, no one can tell who sent it."

Q drop is the same in that the sender's name and account aren't shown to the recipient. However, as a measure against pranks and harassment, its privacy policy makes clear that the owner of a question box can see the sender's IP address. Instead of promising that you're "completely invisible," our policy is to be honest about what can be seen. If you're sending questions, please use it with this system in mind.

One thing applies to every service: anonymous means "your name isn't shown," not "you can't be identified no matter what you do." With any anonymous service, if there's a malicious post, the sender may be traced through legal procedures. We explain this in more detail in the related articles at the end of this article.

Summary: which service to choose for your purpose

Finally, here's a summary of everything above, by purpose.

If you want a well-known service or want to start quickly with a social media account, Peing is a candidate. It has been around a long time, and its official page also mentions the feature for sharing answers with a question image.

If you really don't want to see insults or negative content, or you want to collect feedback on your creative work, Marshmallow, whose selling point is a design where "insults don't come," is a good fit.

If you want to use an app and get notifications, try Querie.me or mond, which offer iOS and Android apps.

If you want to start quickly with just an email and no linked social accounts, or you care about a system that lets the owner see sender information (IP address) as a protection against trolls, Q drop is a good match. It works entirely in the browser, so there's nothing to install.

On pricing, what we could confirm from official pages is that Marshmallow has a paid premium membership and that Q drop is free. We couldn't find the pricing of the other services on their official top pages, so please check each official site before using them. In the end, the most reliable way to decide is to actually try several services and compare how easy their dashboards are to use and how their filters feel. Please note that this comparison is based on what each service's official pages said as of August 2026 and doesn't reflect any changes made since then.
