Common Questions

Is there a Superhuman discount code or coupon?

Superhuman does not offer public discount codes or coupons. The only way to reduce the price is annual billing ($25/mo instead of $30/mo) or getting a referral link from an existing user for one free month. If the price is a concern, CMDK offers the same core features starting at $9/mo with a $169 lifetime option.

How can I get Superhuman for cheaper?

Superhuman's cheapest option is $25/mo on annual billing ($300/year). There is no student discount, no startup plan, and no way to negotiate. CMDK offers the same productivity features (command bar, shortcuts, read receipts, reminders) for $9/mo, $79/year, or $169 for lifetime access.

Is Superhuman worth $30/month?

Superhuman is generally worth it only for professionals processing 100+ emails daily where raw speed is the bottleneck. For most Gmail users, the same productivity gains are available in CMDK for a third of the price, without leaving Gmail or learning a new interface.

Does Superhuman have a free trial?

No. Superhuman does not offer a free trial or free tier. You must commit to $30/mo to try it. CMDK offers a 15-day free trial with full access to all features, no credit card required.

How much does Superhuman cost per year?

Superhuman Starter costs $360/year on monthly billing or $300/year on annual billing. The Business plan is $480/year ($396 annually). CMDK costs $79/year or $169 for lifetime access with no recurring payments ever.

Is there a cheaper alternative to Superhuman?

Yes. CMDK offers command bar, keyboard shortcuts, read receipts, natural language reminders, split inbox, and one-click unsubscribe starting at $9/mo. It works inside Gmail as a Chrome extension, so there is no app to switch to. 15-day free trial, no credit card needed.

Does Superhuman offer a lifetime plan?

No. Superhuman only offers monthly and annual subscriptions with no lifetime option. CMDK offers a $169 lifetime plan where you pay once and use it forever.

Can I get a refund on CMDK?

Yes. CMDK offers refunds no questions asked within 30 days of purchase.

Have people actually switched from Superhuman to CMDK?

Yes. Hundreds of Superhuman users have switched to CMDK. One user said: "I was paying a massive monthly subscription just for a clean interface and fast keyboard shortcuts. CMDK provides the same Inbox Zero experience and speed for a fraction of the cost." Another said: "It doesn't force you to use all of the latest AI tools that I never wanted or needed. Kind of the best of all worlds."

Loved by customers all across the world

Nice app. I like Gmail UI, but the shortcode options of Superhuman. So your app is the best of both worlds!

Superhuman Pricing vs CMDK | Save $250+/year

Brian Dainis

Literally the best email extension you could get. Amazing alternative to Superhuman. Super clean and just works. Definitely worth the price and they are super responsive to feedback.

Danny Nielsen

Solid extension that provides many of the key benefits of MUCH pricier tools. Even better that this lives in Gmail, so you can use other extensions as well.

Zachary Eisenstat

Great - simple as it says, but adds a bunch of convenient time saving features. I don't need a full on client, I just need my Gmail to be fast, and this does it.

Dilip Goswami

Really good and helpful. And the developer was even very responsive to feedback!

Dominic Roser

This is awesome. It massively speeds up and simplifies usage of Gmail. Great pricepoint too, and the developer is super active and amazing at feedback and improvements.

Brent Maxwell

Love it! This extension helps me fly through my emails so I can get out of my inbox and back to revenue producing work. And great support!

Bill Brelsford

Works like a charm! Exceptionally GREAT SUPPORT - even for as small language as Hungarian. It can totally replace Superhuman.

Zoltán Szabó

I have started using CMDK as a layer over my gmail. Once I got used to it I love it. CMDK provide real-time support - most impressive!
