Tellonym and MirrorBox both let people send you anonymous messages, but they're built around different ideas. Tellonym is a social app: you answer "Tells" on a public profile that other users browse. MirrorBox is a bio link: one link for your story or bio, a private inbox, and you decide what ever goes public.
NOTE
Quick answer: Pick MirrorBox if you want a link for Instagram, TikTok or Snapchat that anyone can use in a browser, with songs, "describe me in 3 words" and other card types, and a private inbox by default. Pick Tellonym if you want an anonymous Q&A community with a public feed of answers, and you meet its 17+ age rating.

A public feed vs a private inbox#
On Tellonym, answering a Tell usually means posting it to your profile, where followers scroll through your answers. That's fun if you want an audience, but it means your answers live on a social network.
On MirrorBox, every message lands in your private inbox first. You can:
- answer it on your story, so it lives on Instagram for 24 hours,
- publish an answer under the card on your page,
- pin it to your public page, or
- just keep it to yourself.
Who can send you messages#
Tellonym lets you accept Tells only from registered users, and its app encourages senders to sign up (eSafety Commissioner).
MirrorBox is web-first. Anyone who taps mirrorbox.me/yourname can send a message in their browser in a few seconds, without the app or an account. If you'd rather only hear from signed-in people, you can switch that on.
More than text#
Tellonym is built around text Tells. MirrorBox lets you choose from six card types:
- anonymous notes and questions (ideas for story prompts),
- songs (40 songs people send),
- "describe me in 3 words", which builds a portrait of how friends see you,
- memories and vibe checks.
You can also start an anonymous chat from any message. The sender stays anonymous and can choose to reveal who they are. Nobody can pay to unmask them.
Pricing#
Both are free to use. Tellonym's App Store listing shows paid Tellonym Plus plans (App Store). On MirrorBox, everything you need to receive and answer messages is free, and MirrorBox+ is optional for page themes, insights, the full friends' portrait and premium story templates.
Safety and age#
Both apps have word filters, blocking and reporting. Tellonym is rated 17+ or 18+ on the App Store depending on the listing (Internet Matters).
MirrorBox's minimum age is 13. Accounts need a birth month and year, optional emails are off for anyone under 18, spam and hate filters are on by default, and you can add muted words or pause your inbox at any time. See the community guidelines.
Which one should you pick?#
- Choose MirrorBox for a story or bio link, a private-by-default inbox, more card types and anonymous chat.
- Choose Tellonym if you want a public Q&A feed and a community to browse, and you meet its age rating.
