This extensions adds the same shortcuts and workflows that you love and have gotten used to. Extra handy for times you have to use Gmail or if you are looking to stop using Superhuman, but your shortcut muscle memory still wants to use the same shortcuts.
Command Center for emails - Cmd+K or Ctrl+K All your email actions - mark read/unread, report spam, archive, add label, compose etc available in an easy to use command bar. You wouldn't need to use your mouse again (mostly). An alternative to Superhuman, if you will.
Nudges to learn keyboard shortcuts Whenever you use your mouse, CMDK gently prompts you with the keyboard shortcut that you could have use instead. Migrate to using shortcuts at your own pace.
Quick navigation through your email
Jumping between your Inbox, Sent, Drafts, or Folders is now an easy to use command with CMDK. Hit Esc to go back to the previous screen from wherever you are. You don't need to pay $30/mo to give you shortcuts when Gmail already has them ;)
Quick actions for Opening links, RSVP, Unsubscribe, and attachments RSVP to calendar invites, open attachments or links, or unsubscribe from those pesky emails using the Command Center.
Browser extension that works everywhere Works on all popular browsers. You can continue using extensions like Grammarly, Streak, and Mixmax while being faster at email.
Email is heavy, hard, and plenty. But email does not have to be a pain or expensive. Mastery over your email is the quickest way to a healthier relationship with it, and CMDK will get you there.
RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps โ not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.
A free tier includes 400 exercises with flat-style 512ร512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings โ exclusive to that tier.
Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.

RepDBCMDK for Gmail's answer
The only app out there which adds superhuman type keyboard shortcuts to Gmail, without the hefty price of $30/month.
RepDB's answer:
RepDB is sold as a one-time download, not a metered API โ you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.
CMDK for Gmail's answer
I was a user of Superhuman for over 2 years and got tired of paying $30/month. I wanted the best features of Superhuman right inside Gmail, and thats when I started working on this browser extension.
RepDB's answer:
RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.

Javascript, LLMs.
CMDK for Gmail's answer
If you want to continue using Gmail but also want the Superhuman email experience.
RepDB's answer:
Most alternatives are subscription APIs โ you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.
CMDK for Gmail's answer
We have executives from Reddit, Netflix, Microsoft, Flipkart using Simplehuman.
CMDK for Gmail's answer
Small business owners, founders, executive assistants, sales reps. Anyone who uses email a lot in their day.
RepDB's answer:
Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.
