How to enable the MemoKey keyboard

MemoKey is a notes-first keyboard with a tab strip at the top. Notes shows your saved notes, and a tap inserts one into the field you are in; with the app lock on, this is the tab that asks for your passcode.

Keyboard has letters, 123 and a VN key for Vietnamese Telex, so you can type a quick reply without switching keyboards. It has no autocorrect or word suggestions, and nothing you type is stored. Kaomoji inserts kaomoji by category. Draw, on iPhone and iPad only, is a place to sketch.

Keyboard and Kaomoji work while MemoKey is locked and without Full Access. For long writing, your usual keyboard is still the better choice.

On the Notes tab, the bottom row has a Paste key. Tap it to insert what you copied last — a link, an address, any text — right where you type, without leaving the field or switching keyboards.

On iPhone, Paste needs Allow Full Access. Without it, the key shows a notice asking you to turn Full Access on instead of reading the clipboard.

On Android, Paste reads the clipboard only in the moment you tap it. With the app lock on, Paste on both systems first asks for your MemoKey passcode, so nobody can read what you copied while MemoKey is locked.

From MemoKey 3.12, a tag can open by itself in the keyboard. In Manage Tags, tap a tag and under Open in keyboard when… pick Email field, Phone field, Web address field or Number field. When you tap such a field in any app, the keyboard’s Notes tab opens on that tag. Tap another chip and your choice stays until you move to the next field.

On Android you can also pick apps under In app…: the apps you used the MemoKey keyboard in show up there. iPhone and iPad keyboards can’t see which app you are in, so this part is Android only. Also on Android, Settings → Keyboard → Remember tag per app opens the tag you used last in each app. It is off by default, stays on your phone, and Clear remembered apps makes the keyboard forget it.

Guide to tags and pinned notes

From MemoKey 3.12, keep a reply you just typed as a note without leaving the chat: tap Save note at the end of the chip row on the Notes tab, choose Text before cursor or Clipboard, add a title and a tag if you like, and tap Save. The note shows on the Notes tab with a Pending badge, and you can insert it right away.

The keyboard never writes your notes itself: the note waits on your phone and MemoKey adds it the next time you open the app, with Undo. On iPhone and iPad, Save note needs Allow Full Access. A saved note is never locked, and while MemoKey is locked the keyboard offers Save note only after you enter your passcode.

Fill line by line fills a form field by field from one note, like the Shipping details example: touch and hold the note, tap Fill line by line, then tap Insert once for each field (name, phone, email, address). Only the value after a label such as “Phone:” is inserted, never the label.

From MemoKey 3.14, English words typed with VN on stay as you typed them: “text” no longer becomes “tẽt” when you press space, while Vietnamese words still get their accents, on iPhone and Android. Turn it off in Settings → Keyboard → Auto switch English/Vietnamese. Letters also pop up as you press them, and holding Delete speeds up and then deletes whole words; on iPhone the Keyboard tab uses the iPhone keyboard’s layout, with a #+= page for symbols.

From MemoKey 3.16, the keyboard can rewrite the text you are typing with AI, using your own API key. It is off by default. Open Settings → Keyboard → AI rewrite, turn on AI rewrite in the keyboard and accept the notice. Then choose the Provider (OpenAI-compatible, Anthropic or, from MemoKey 3.17, Google Gemini), paste your API key, enter the Model ID and test the connection. Leave Endpoint URL blank unless you use your own endpoint. You get the key from your provider, and the provider charges you for what you use.

Under Actions you start with Rephrase, Shorter, More professional and More friendly. Tap one to change its Button name or Instruction, use the arrows to reorder them, and tap Add action to make your own, such as “Translate to English” (up to 12).

While typing in any app, select some text or just leave the cursor in the field, open the MemoKey keyboard, tap AI and then an action. The rewritten text replaces yours and is also copied; an Undo chip puts the original back for a few seconds. If the text changed while the AI was working, nothing is replaced and the result waits in your clipboard. On iPhone and iPad, AI rewrite needs Allow Full Access.

If an action fails, the keyboard says why: the API key was refused (check or replace the key), the model or endpoint was not found (check the Model ID and Endpoint URL), the provider’s rate limit or quota was reached (try again later), or there was no connection or no answer within 30 seconds. Only the text you rewrite is sent, straight from your phone to your provider; MemoKey has no server and keeps no copy, your saved notes are never sent, and the key stays on your phone until you remove it.

From MemoKey 3.4, write {date} or {time} in a note: when the keyboard inserts it, they become today’s date and the current time in the app’s language. The saved note keeps {date} and {time}, so it is up to date every time.

From MemoKey 3.6: touch and hold a note to read all of it before inserting. Inserted the wrong one? An Undo chip removes it for about 8 seconds (not when Switch back after inserting is on). The Recent chip lists the last 10 notes you inserted, and the keyboard opens on the chip you used last.

From MemoKey 3.7: in the keyboard’s fill-in fields, the VN key turns on Telex (aa â, ow ơ, dd đ, s f r x j for the tones), so “Vieejt” becomes “Việt”. It is on by default when MemoKey is in Vietnamese. Touch and hold a letter to type it as it is, for an English word, a name or an e-mail address.

The keyboard’s fill-in fields remember the last 5 answers for each field (on your phone only, never for locked notes; touch and hold a chip to forget it; turn off or clear in Settings → Keyboard) and have a Paste key next to 123 that adds the text you copied to the field on one line. On iPhone and iPad, Paste needs Allow Full Access.

The keyboard also inserts kaomoji: the Kaomoji tab shows MemoKey’s kaomoji by category (Happy, Love, Sad and crying, Shrug and table flip, Cat, Bear and more), and a tap inserts one. Recent keeps the last 20 you inserted. It works while MemoKey is locked and, on iPhone and iPad, without Full Access. Turn it off in Settings → Keyboard → Show Kaomoji.

Guide to templates and placeholders

The keyboard reads only your MemoKey notes. It does not collect what you type and sends nothing, unless you turn on AI rewrite: then the text you choose to rewrite goes to the AI provider you set up, with your own key. Everything else works offline.
