Frequently asked questions about Shortwave

What is Shortwave?

An email client that rebuilds the inbox around AI assistance. Rather than adding a summarising button to a traditional client, it treats search, filtering, summarisation and drafting as the core of the product. It connects to an existing mailbox, so you keep your address and your history — what changes is the interface on top of them.

What does the AI actually do?

Three things worth naming. It summarises long threads so you can grasp the state of a conversation without reading every message. It answers questions about your mailbox in plain language — essentially natural-language search. And it drafts replies in your style. The summarisation and search are the parts that change daily work; the drafting is a convenience that still needs review before sending.

Does it work with my existing email account?

Yes, that is the premise — it is a client rather than a new mail service, so it works with an account you already have rather than requiring you to migrate addresses. It is available across desktop and mobile. The specific providers supported are worth confirming on the vendor’s site, since client support varies by provider and by how each handles authentication.

Is Shortwave free?

It is listed on ToolFlect as freemium with a score of 4.3. There is a usable free tier, with paid plans adding AI usage allowances and team features. Because AI assistance consumes inference, the limits that matter are on the AI side rather than on mailbox size — so check the allowance against how heavily you would lean on summarisation and search.

Is it private?

It is an email client, so it necessarily has access to your mail — that is inherent to what it does, not a defect. Any client that summarises or searches your messages must be able to read them. The relevant questions are what is stored, for how long, and whether message content is used for anything beyond serving you. The privacy policy is the authoritative answer, and it is worth reading before connecting a work account.

What are the limitations?

Changing email client is a significant habit change, and most people underestimate it — the switching cost is the main barrier, not the price. AI summarisation can miss nuance in a delicate thread, so it is a poor substitute for reading carefully when the stakes are high. And as with any client, you are dependent on continued support for the providers you use.

Use cases for Shortwave

Long threads you need to catch up on

Where a conversation has run to twenty messages and you need the state of play rather than the history, summarisation saves reading time on every occasion. It is most useful returning from time away, when the accumulation of threads is the obstacle rather than any single message.

Finding an email you cannot describe precisely

Traditional search requires you to remember a word that was actually used. Natural-language search lets you describe what you are looking for — who it was from, roughly when, what it was about — which is how memory actually works. For anyone with years of mail, that is the most broadly useful feature here.

A high-volume inbox that needs triage

Where the daily volume is high enough that reading everything is not realistic, AI-assisted sorting and summarising changes the shape of the task from reading to deciding. The professional audience the product targets is exactly the one whose inbox has become a queue.

Pricing

Shortwave carries a freemium listing and a 4.3 score on ToolFlect. Paid plans scale with AI usage and add team features, which means the cost tracks how much you lean on summarisation and natural-language search rather than how much mail you store. For a light user the free tier may be sufficient; for someone in email all day, the AI allowance is the figure to model. Confirm current plans on the official Shortwave site.

Alternatives to Shortwave

The alternatives range from AI-equipped clients to built-in provider features:

• Superhuman — a fast, keyboard-driven client with AI features, aimed at the same professional audience and priced higher.
• Gmail with Gemini — summarisation and drafting built into the provider itself, free and requiring no new client.
• Spark — priority sorting and a smart inbox, free for personal use with paid team features.
• SaneBox — sorts server-side so any client benefits, rather than replacing your client with an AI one.

ToolFlect lists the email and productivity tools in this space side by side.

How to get started with Shortwave

Try it on one account before moving everything

Connect a single mailbox — ideally a busy personal one rather than your primary work account — and use it for a week. Email clients are habit-dependent, and the question is whether the new interface suits how you work. Finding out on one account is cheap; finding out after migrating your whole team is not.

Use natural-language search on a question you already know the answer to

Ask it for something you could find manually and compare the results. That gives you a realistic sense of its accuracy and its limits before you depend on it for something you cannot check — which is the only honest way to evaluate a search feature.

Read the summary against the thread when the stakes are high

Summaries are reliable for routine correspondence and can flatten nuance in anything delicate — contractual, personal or contentious. For those threads, read the messages. Knowing which category you are in is the judgement the tool cannot make for you.

Decide the privacy question before connecting a work account

Establish what your organisation permits regarding third-party access to business email, and read the client’s own policy on what is stored and what message content is used for. Any AI mail client needs to read your mail to summarise it; that is inherent to the feature set. Making the call deliberately is different from making it by default.
