Shortwave Review 2026: Features, Pricing, and Verdict
Shortwave is an AI-native email client built for Gmail by engineers who worked on Google Inbox, and the lineage shows. Bundling, AI search and thread summaries are the strongest implementations of those ideas available. If you are on Gmail and want the inbox itself to be smarter, it is one of the best options in the category and it is cheaper than the obvious alternative.
If your work arrives across Slack and Teams as well as email, or if you are on Outlook, the fit is narrower. Below is what it does, what it costs, what reviewers complain about, and where it stops. Prices were checked against Shortwave’s own pricing page on August 6, 2026.
Key takeaways
- Shortwave is Gmail-first. That is the single biggest determinant of whether it suits you.
- Pro is $18 per seat monthly. The team plans are Business at $30, Premier at $45 and Max at $120, all per seat per month. Shortwave bills monthly only.
- The AI is genuinely native, not bolted on: bundling, semantic search and summarization are built into how the client works.
- It is an email client. Slack, Teams and WhatsApp sit outside its scope.
- Cheaper than Superhuman, whose standalone Mail plan starts at $25 per seat billed annually, or $30 monthly.
What is Shortwave?
Shortwave replaces the Gmail interface with an AI-native one. Mail still lives in your Google account; what changes is everything on top of it.
Bundling groups related mail so the inbox reads as a handful of stacks rather than a hundred separate items, which is the clearest inheritance from Google Inbox. AI search is semantic, so you can describe a message rather than recall its keywords, and this is the feature long-time users cite most. Thread summarization compresses long chains into something readable. It also drafts replies, and offers automation for the repetitive parts of triage.
The design assumes you want a better inbox, not a different container for work.
Shortwave pricing
| Plan | Per seat / month |
|---|---|
| Free | $0 |
| Pro | $18 |
| Business | $30 |
| Premier | $45 |
| Max | $120 |
Free and Pro sit under an Individual toggle on the pricing page; Business, Premier and Max sit under a Business one. There is no annual billing option and no published Enterprise tier. The comparison people usually want: Shortwave’s entry paid tier undercuts Superhuman, whose standalone Mail plan starts at $30 per seat monthly or $25 billed annually. Against tools that are not full email clients, Shortwave looks expensive, which is the right way round given it replaces the client rather than sitting beside it.
What people like about Shortwave, and what they don’t
The praise concentrates on AI search and bundling. Users describe finding messages they could not have found in Gmail, and an inbox that stays legible at volume. The AI is well integrated rather than a sidebar bolted onto a conventional client, and that shows in daily use.
The complaints are about scope and platform. It is Gmail-first, which rules it out for Outlook teams. Pricing climbs quickly across tiers for features some expect lower down. And, as with every product in this category, it makes email better without touching what happens to the work inside the email.
Where this+that is different
We build a competing product, so read this with that in mind.
Shortwave makes the Gmail inbox smarter. this+that reads Gmail, Outlook, Slack, Microsoft Teams, Google Chat, and WhatsApp Business, extracts the tasks automatically, and puts them in a shared list with owners and a link back to the source. Workflows are the part you set up, and they run on messages as they arrive, with an approval step before anything sends.
If your problem is that email is hard to read, Shortwave addresses it more directly than we do. If your problem is that commitments made across several channels go missing, an email client cannot see most of them.
Who should choose Shortwave?
Choose it if you are on Gmail, you want the inbox itself to be more intelligent, and semantic search over your own mail sounds like the thing you have been missing. At $18 it is good value against the premium end of the category.
Look elsewhere if you are on Outlook, if a real share of your work arrives in team chat, or if you need work tracked across a team rather than an inbox that reads better.
