Doubleslash: write where you type
How it works
Click into a Gmail compose window or reply box and type \\ (two backslashes) at the start of a word. A picker opens at your cursor. Choose an action with the arrow keys and Enter, or click it. Most actions then open a short prompt field where you say what you want in a few words. Press Enter and Multify does it right there.

- Continue writingPick up where the cursor is

Type less with shortcuts
Keep typing after the backslashes to filter the list. \\wr jumps to Write, and so do \\draft and \\compose. A few more: \\look or \\search for Research, \\more for Continue writing, \\recap or \\tldr for Summarize, \\pdf for Create & attach, and \\apps for Connectors.
You can also type the whole request in one go. \\write a polite no opens Write with "a polite no" already in the prompt field. A space straight after the backslashes closes the picker, so \\ note stays as plain text.

The actions in Gmail
Doubleslash knows which email you're in and reads the conversation you're replying to, so a three-word ask is usually enough.
Write
Writes the text that belongs at your cursor. In an empty email it writes the whole message; in the middle of one it writes only what fits there. It uses the email, the conversation above it, and anything you mention with @.
The new text appears highlighted with a bar that says it isn't added yet. You choose what happens:
- Accept (Tab) keeps it as ordinary text. Carrying on typing also accepts it.
- Reject (Esc) removes it, and the email is back to how it was.
- Try again writes a fresh version from the same ask.
Highlighted text never goes out. If you press Send before accepting, Multify removes it first.
Continue writing
Put your cursor at the end of what you've written and pick Continue writing. Multify adds a few sentences in the same voice and language, without repeating you. It shows up highlighted, same as Write. In an empty email there's nothing to continue, so it tells you that instead.
Link
Pick Link, then type @ and choose something from your Stash or a page. Multify inserts its title and link. A page has to be shared to have a link; for a private page you get nothing rather than a made-up address.
Research
Type what you want to know and press Enter. The Multify panel opens with your email attached and searches the web for that subject, with sources. Your email stays as it is.
Summarize this conversation
Shows up when you're replying to or forwarding a thread. It reads the whole conversation, including messages Gmail has collapsed, and sums it up in the panel: what it's about, the key points, decisions, open questions, and what's being asked of you. There's no prompt to type.
Create & attach something
Ask for a file and Multify makes it in your Files: a PDF, an image, a CSV, or an export from a connected app. It shows up in the panel with an Attach to email button. Nothing is attached until you click it, and files made for an email stay private.
Files over 25 MB, Gmail's limit, can only be downloaded. If you've closed or sent the email by the time you click, Multify says so and offers to attach it to the email that's open now, or to download it.
Connectors
The small row at the bottom opens the Connectors screen in the panel, where you connect apps like Google Calendar, Notion, Slack, HubSpot and Google Drive. Once they're connected, Write and Research can use them when you mention them.
Mention your own stuff with @
In any prompt field, type @ to pull in a task, runbook, page, file, GitHub repo or stash item. Pick one from the list and it becomes a chip. Write uses what's in those items as facts, so you don't have to paste them.
You can add up to 10 mentions to one ask. Backspace removes a chip whole.
On other websites
Doubleslash also works in the text boxes you write in on other sites: a Slack message, a LinkedIn post or comment, a Reddit reply, a Notion block, a GitHub comment, a support ticket. Type \\ the same way. The first time you click into one of these boxes, a small tip beside it reminds you.
On other websites the picker shows Write, Continue writing, Link, Research, Improve, Connectors and Turn off on this site. Summarize and Create & attach need an email, so they stay in Gmail.

Insert or copy
Outside Gmail the text appears in the Doubleslash card first, so the site's own editor isn't touched until you decide. Press Insert (Enter or Tab) to put it at your cursor, Reject (Esc) to drop it, or Try again. The clipboard icon in the corner of the card copies the text instead. If a box doesn't take the text, Multify copies it for you and tells you to paste.
Improve
Select some of your own text in the box, type \\ and pick Improve, and Multify rewrites the selection. Once the first version is ready you can try a different direction: Shorter, Longer, Friendlier, Firmer, Formal, Fix only (spelling and grammar, nothing else), Translate or Summarize. Translate remembers the last language you picked. Improve also lives on the right-click menu and on a small chip that appears when you rest your pointer on selected text; see Right-click & Improve.
Where it stays off
Doubleslash only opens in boxes meant for writing. It stays out of:
- single-line fields and search boxes
- code editors
- any form that asks for a password or a card number
- Google Docs, the extension stores, and Multify's own site
- Overleaf, by default, since LaTeX uses backslashes everywhere (you can turn it back on)
It also can't open in text boxes that sit inside an embedded frame. Some help desks and site builders work this way, including Zendesk, Intercom, HubSpot and the classic WordPress editor. There, write your draft in the Multify panel and paste it in.
To switch it off somewhere else, type \\ on that site and pick Turn off on this site. A note confirms it, for example "Doubleslash is off on app.slack.com. Turn it back on in Multify Settings."
Settings
Open the panel menu (☰) and choose Settings.
| Setting | What it does |
|---|---|
| Doubleslash in Gmail | Turns the picker on or off in Gmail. On by default. |
| On other websites | Turns it on or off everywhere else. Separate from the Gmail switch. |
| Turned off on these sites | The sites you've switched off. Remove one to turn it back on, or type a site to add it. Adding slack.com covers every Slack address. |
Typing \\ in the Multify panel
Doubleslash works where you're writing, not in the panel's own chat box. If you type \\ there, Multify replies with a short note about where it does work and puts any words you typed back in the box, so you can send them as an ordinary question instead.
