Shortwave vs Agentys (2026): AI Email Client vs AI Email Layer
· Sovattha Sok
Shortwave vs Agentys (2026): honest comparison of AI email client ($24–$100/mo, Gmail-only, great search & summaries) vs AI drafting layer ($16.99/mo, Gmail/Outlook/Microsoft 365, drafts you review and send). Includes pricing table and honest limitations for both.
Shortwave is a polished AI email client — natural-language search, thread summaries, a carefully designed interface. Agentys is an invisible layer on top of Gmail or Outlook that drafts replies automatically for you to review and send. Different tools, different trade-offs.
Where Shortwave genuinely wins
Skipping Shortwave's real strengths would make this comparison worthless, so here they are stated plainly. The single most distinctive feature is natural-language email search. Type "the contract Marcus sent in October about the Denver project" and Shortwave finds it — not because it matched keywords in the subject line but because the AI understood the semantic content of the query. This is a capability Agentys does not have. Agentys drafts replies; it does not offer a conversational search interface over your historical email archive. If you frequently need to resurface old threads, attachments, or specific conversations with particular contacts, Shortwave's search is a material improvement over Gmail's keyword-based index. Users who work in deal-heavy, project-heavy, or research-heavy environments — lawyers, investors, consultants — routinely cite search as the reason they stay.
Thread summaries are the second real win. On the Business plan ($24/seat/month, billed annually) and above, Shortwave generates a concise AI summary at the top of each thread when you open it. For long project threads, client discussions that span weeks, or any conversation you have been cc'd on but need to catch up on quickly, this is a concrete time-saver. You spend 10 seconds reading a summary rather than 3 minutes scrolling through 25 replies. Agentys does classify and prioritize incoming mail automatically, but it does not surface the same kind of on-demand, in-client thread summary that Shortwave provides during the reading experience. A third honest advantage: Shortwave's design quality is uncommonly high. The product team has clearly iterated carefully on the interface, and it shows in details that matter — consistent visual hierarchy, a keyboard shortcut system that is comprehensive and teachable, shared channels that actually work for small teams. For someone who spends 3–4 hours per day inside email and experiences real friction from Gmail's aging UX, that design lift is worth real productivity. Shortwave's pricing runs from $24/seat/month (Business, billed annually) to $36 (Premier) and $100 (Max), with a 14-day free trial but no permanent free tier as of 2026.
The composition bottleneck: what Shortwave cannot do
Shortwave is an excellent reading and searching tool. It is not a writing tool in the way that matters for professionals who spend most of their email time composing replies. The AI autocomplete feature within Shortwave helps you finish sentences faster — similar to Gmail's Smart Compose — but it still requires you to be sitting at your desk, initiating each reply, reading each thread, and making each decision. The cognitive overhead does not go away; it gets a slight reduction in the typing portion. That overhead is expensive: it takes most people around 20 minutes to fully recover from a single email interruption during a focused work block, and even when you feel recovered after a few minutes, your error rate and output quality indicate otherwise. Shortwave's design quality reduces friction inside the email experience. It does not change the frequency with which email pulls you out of deep work during the day.
Agentys addresses that problem at the root. When you ask it to reply, Agentys reads the thread, evaluates context, references your sent history to match your writing style per contact, and produces a ready-to-review draft — you review, adjust, and send each one. Email eats a large share of the average knowledge worker's week, split between reading and composing, and Agentys attacks the composing half. An honest limitation here: Agentys does not have natural-language search over your email archive. If you need to find "the NDA from the Vancouver client, April 2024" by describing it in plain English, Shortwave does that and Agentys does not. That is a genuine capability gap. For professionals whose primary frustration is time-in-inbox rather than search-and-retrieval, the calculus favors Agentys. For professionals who spend significant time digging through old email — legal, finance, research roles — Shortwave's search is built for that job. The question worth asking before you choose is: where does your time actually go? If it goes to composing and reviewing, Agentys reclaims it. If it goes to finding, Shortwave's search is built for that.
Pricing and the real cost of switching
Shortwave's pricing, confirmed on shortwave.com/pricing in May 2026, runs as follows: Business at $24/seat/month (billed annually), Premier at $36/seat/month (annually, most popular tier), and Max at $100/seat/month (annually, for the highest AI usage quotas and live training). There is no permanent free plan — only a 14-day trial. The jump from $24 to $100 between Business and Max is steep, and the differentiation is primarily about AI usage quotas: Business gives you AI search over five years of history with a maximum of 50 threads per query; Premier doubles the usage and extends search to unlimited history at 100 threads; Max goes to 150 threads and 6x the base AI budget. For most individual professionals, Business or Premier is the relevant decision. At $24–$36/seat, Shortwave is priced at roughly the same tier as Agentys.
Agentys starts at $16.99/month for the Starter plan, with Professional at $29.99/month ($24.99/month billed annually), and a 7-day free trial. The comparison at face value is close: $24–$36 for Shortwave versus $16.99–$29.99 for Agentys. But the real cost of Shortwave includes the switching cost, which is rarely zero. Migrating an individual Gmail user takes hours; migrating a team of five takes days of coordination, training, and support overhead. That cost is front-loaded: you pay it before you see the return. Agentys has no switching cost in the traditional sense — it layers on top of what you have already — so the return starts on day one. The second cost consideration for Shortwave is lock-in. Once your team has rebuilt their workflows inside Shortwave — new shortcuts, new filter setups, habits around the channel view — leaving is its own project. That is not necessarily a reason to avoid Shortwave; it is a reason to decide deliberately rather than on a trial impulse.
