I've been banging on the doors to get access to Superhuman's AI for months — all the way back in March — an eternity in AI land! And now, here it is!
As expected, the implementation is elegant and subtle — staying out of the way until you need it.
No doubt there'll be more improvements to come, but having a personalized AI agent that can write emails on my behalf and in my voice? — yes, this is exactly what being Superhuman is all about.

Hey folks, @rahulvohra here from Superhuman 👋
At the start of the year, it was clear that LLMs would change how we work. At Superhuman, we naturally wondered how LLMs could be useful when reading and writing email. And of course, it wasn’t just us wondering. LLM features rapidly became our top user request, eclipsing the next most requested features by orders of magnitude!
We quickly created a small but plucky AI team. It was chaotic, and at times painful. But we persevered.
I am now thrilled to share that Superhuman AI is available to all customers!
To get going, reload Superhuman, and then hit Cmd+K (Mac) or Ctrl+K (Windows) → Activate Superhuman AI. To use Superhuman AI, just hit Cmd+J or Ctrl+J in any email.
With Superhuman AI, you can:
🗯️ Turn an idea into an email

We’ve all struggled with long conversations. Worse, we’ve replied or forwarded, making even more work for our colleagues and coworkers. Just use Superhuman AI to summarize. You’ll go much faster, and everybody else will too.

We are all so excited to hear what you think! Please do reply here and let me know 🙏
@william_wright3 👋 you should be able to get started now with Cmd+K (Mac) or Ctrl+K (Windows) → Activate Superhuman AI
@rahulvohra FINALLY 😭😭😭 This is what I’ve been waiting for! Can you please confirm if it’s available to all existing users because I can’t seem to access it 🙁
@rahulvohra @mahad_ahmed, I just tried the command and it worked. You guys should really put in this post and/or website and/or the app something that displays how to use it :)!
@william_wright3 Thanks 🙏 I see the shortcut to activate it. Curious if SH shares share our data anonymized or not 😅
thanks @rahulvohra - as a user from day one, I can say that this is an absolute gamechanger saving me even more hours per week - best is respond in my style - look forward to future AI features which I know are on roadmap!
I use the summarize feature when forwarding to colleagues so they do not have to “spelunk” the whole thread. It is great!
I've been using Superhuman for about six months now, and it's the best email platform I've ever used - the customer service team is the most impressive part: I often get a response the same day if I have questions or even product feedback.
The AI writing tool is fantastic, and I've been waiting patiently for it. I'm hoping that it learns from my feedback and gets better at writing in my voice.
I can’t emphasize how cool Superhuman is — been using it for years and it just keeps getting better! Mad props to Rahul and the team! ❤️
I have been using Superhuman for years now and this is one of the best, obvious and needed feature, implemented in the best possible way. It would be great if I can fix AI drafts instantly in the AI modal screen. Many times I wanted to fix something small before hit "enter", or even continue working with this draft with AI tool, before I actually get the result in the email screen. Thanks!
@timraiter thank you, your words have made our collective days! we did think about letting you edit in the AI modal directly, but then we'd have a textarea in a textarea, and we thought it would get confusing. but maybe it wouldn't be that bad!
Also, curious, there is an always available option "rewrite in my Voice". Shouldn't it be by default? Probably all AI drafts should be "in my voice", so then I can make them shorter, longer, and summarize. I will never need a corporate and super official or really funky voice in my emails :)
@timraiter we built it to write in your voice by default! We chose to keep the option in the menu as well for times where it didn't write quite on-brand in the first pass, or where you are using the AI to edit some text that's already in your email body.
@timraiter we chose to not allow direct editing in the results window, but you can always give it a follow-up prompt to keep tweaking the result! just type your instructions in the input field right below the result and hit enter to give it some follow-up directions.
I often tell it to add a concept or to fill in a placeholder in the first result i get back.
@islam_sharabash1 thank you!! but does it top split inbox, I mean pinned labels!?
Congrats on the launch! Can you talk a bit about how you guys are dealing with data privacy here?
@jessicakchen we use various models of ChatGPT under the hood, so please only use Superhuman AI if you would be comfortable doing the same thing via ChatGPT. (As you probably know, OpenAI has committed to not using data provided via the API as training data.)
@rahulvohra Got it! I assume then it will be possible to use Superhuman without using Superhuman AI? Or that we can apply Superhuman AI to certain mailboxes but not others? (I'm specifically thinking that work email is more sensitive.)
@rahulvohra @jessicakchen during early access, Superhuman AI is an opt-in feature that you can enable for each individual email address you have in Superhuman. So in your example, you could turn it on for a personal account only. Just switch to that account in Superhuman, hit CMD+K (or CTRL+K), and type 'AI' to find the activation path 🙏
The setup process does reference some of your recent emails to get a sense of your writing style, but after setup it will only show up when you tell it to (by hitting CMD+J in a conversation) and only gets access to that current conversation's context when you send it instructions.
@sentry_co at some point in the not-too-distant future, it will be really quite hard to tell!
Superhuman are absolute rockstars when it comes to implementing every feature. So much thought goes behind each and every improvement, and they somehow never make the product feel more bloated, and absolutely NEVER slow the experience down.
Superhuman AI is no different, in fact, it's a perfect example of them making things *faster*.
I must admit, it took some getting used to, having an AI assistant in my inbox with me. But more and more I am finding myself using it to get back to emails — especially the ones I know I should have replied to yesterday. It really helps kick off a draft and eliminate the "blank canvas" issue I often face.
Keep it up, Superhuman team! Always an inspiration! ❤️
