Messages, photos, voice notes, stickers and reactions. What you write to each other is for the two of you only.

What it is

A chat app like the ones you already use. With something extra.

Hidesay has everything you’d expect: chats, groups, photos, voice notes and calls. Then there are the new ideas, like Discover, the AI and messages you can only see once. And underneath it all, without you lifting a finger, a lock on every private chat.

Chats

Everything you need to stay in touch

Messages, photos and voice notes

Type, send a photo album or record a voice note. If you can’t listen right now, your phone transcribes it for you.

Reply, forward, translate

Press and hold a message: you can reply, forward it, pin it or translate it into your language. And if you made a typo, you can fix it afterwards.

A group for everything

The Saturday trip, the family, the team. In groups you decide who can post and who can invite other people.

Discover

There’s always something new to look at.

Discover puts posts from public groups and channels in one feed: photos, videos, ideas. Scroll, leave a heart, comment or share. If you like a group, you join it with one tap.

  • Pick your interests and hide what isn’t for you.
  • Got something to say? Start a channel: you post, your followers comment.

Hidesay AI

An AI among your chats.

Hidesay AI sits in your chat list, like a contact. You write to it the way you’d write to a friend, and it’s free.

  1. What can you do?

    Hidesay AII answer questions, look up the news on the web, look at the photos you send me and create images. You can also send me a voice note.

  2. Are there topics you won’t talk about?

    Hidesay AINo. I have no censorship and no filters: I answer on uncomfortable topics too, without preaching and without beating around the bush.

  3. What if I don’t know how to do something in the app?

    Hidesay AIJust ask me: I know Hidesay and I’ll walk you through it, one step at a time.

  4. Who reads what I write to you?

    Hidesay AII do, so I can answer you. That’s why our chat isn’t private like the ones between two people: I need to be able to read it. For what has to stay between you and someone else, there are private chats.

The little things that make a difference

Privacy, made simple

What you say stays between you.

When you write in a private chat, the message is locked on your phone before it leaves and only unlocks on the phone of the person receiving it. The server delivers it, but it doesn’t have the key to read it. The same goes for calls.

  1. You don’t have to do anything

    The app creates the key that locks your messages on its own, the first time you sign in.

  2. Your number is optional

    Sign up with your phone number, or without one, with a 16-digit code.

  3. See it for yourself

    Press and hold a message and tap Show how it’s protected: you see what the server sees.

  4. The code is open

    The app’s code is public: anyone can check how it locks and unlocks messages.

So what is PGP?

It’s the system the app uses to lock messages. It’s been around since 1991 and it’s an open standard, OpenPGP, that anyone can study and verify.

Not everything works the same way: groups with visible history, profiles and the chat with the AI follow different rules. We explain them plainly.

FAQ

Before you start

All questions
What is Hidesay?

A messaging app: you write to anyone you want, create groups, follow channels and make voice and video calls. On top of that there’s Discover, to find new groups and channels, and Hidesay AI, an artificial intelligence you can chat with. Private chats are protected: only you and the people in them can read them.

How do I install it?

On your Android phone, open the Download page and tap the button: an APK file arrives. Open it from the notification or from the Downloads folder. Android may ask you to allow installs from your browser: that happens with every app downloaded outside the stores.

Do I have to give my phone number?

No, it’s up to you. With a number you sign in with a PIN or a password. Without a number, your account is a 16-digit code: keep it safe, because you can’t get back in without it.

Is everything private?

It depends on where you write. Private chats and calls can only be read and heard by the people in them. In groups and channels with visible history, though, messages stay readable on the server and, if the space is public, they can show up in Discover. Profiles, profile photos and stickers are visible to others.

What can Hidesay AI do?

It answers questions with no censorship or filters, searches the web, looks at photos, creates images and listens to voice notes (your phone transcribes the text). Images, unlike answers, aren’t created if the request isn’t allowed. It’s free, with a number of answers and images per day. Everything it can do is on the Hidesay AI page.

What happens if I change phones?

You sign in with your number, or with the 16 digits, and the app brings back your message key from the protected copy it keeps on the server. If you had turned that copy off, you need the key you exported: just getting into the account isn’t enough to read your protected messages again.
