AI Email Assistants
Best Shortwave Alternatives
AI-powered email client focused on productivity, summaries, and collaboration
In-depth overview
Understanding Shortwave and its top alternatives
Shortwave rebuilds the Gmail experience around AI assistance rather than adding assistance to a conventional client. Its assistant can search and reason across your entire mail history conversationally — answering questions like what was agreed with a particular client, or what is outstanding from a thread — which is a different capability from summarizing the message in front of you and the most genuinely useful thing in the product.
Around that sit AI-organized bundles that group mail by type, thread summaries, scheduling assistance, and drafting in your voice. The organizational features address the underlying problem that inbox volume is mostly low-value mail competing for attention with the few messages that matter. Whether automatic grouping helps or obscures depends on how much you trust it, so evaluate it over a few weeks rather than a day.
It is Gmail-only, which narrows the audience sharply but allows deeper integration than a provider-agnostic client. For Google Workspace users that is fine; for anyone on Outlook it rules the product out entirely. Pricing sits below Superhuman while leaning harder on AI features, which makes it the better-value choice for people who want assistance rather than pure keyboard speed.
The comparison worth making first is against Gmail with Gemini, since Google has added summarization, drafting, and mailbox search to the client you already have, and organizations on Workspace may hold that licence already. Shortwave's advantage is a more capable assistant and better organization; measure that against paying nothing extra. As with any third-party client, confirm what mailbox access is granted and how message content is processed and retained, particularly if your mail contains client-confidential material.

How to choose a Shortwave alternative
The tools most often weighed against Shortwave are Superhuman, ChatGPT and Google Gemini. They overlap with Shortwave on the core job but diverge on how much control you get, how much setup they expect, and what they cost at the volume you actually work at.
Pricing models differ more than headline numbers suggest: ChatGPT and Google Gemini offer a free tier, which is enough to judge output quality before paying. Work out your realistic monthly volume first, because the cheapest option at low usage is frequently the most expensive at scale.
The capabilities that separate these options — rather than the ones they all claim — are reasoning, fast workflows, shortcuts and ai assistance. Those are the axes worth testing directly, since every tool in ai email assistants markets the same general promise and only differs once you run your own work through it.

Does it work with Outlook?
No — it is Gmail-only, which allows deeper integration but rules it out entirely for anyone on Outlook.
Why not just use Gmail with Gemini?
