Leaving Superhuman in 2026? Honest guide covering the real churn reasons (post-Grammarly $40/mo price, assistive-only AI) and the alternatives mapped to each need: Agentys $16.99/mo for automatic drafting, with Shortwave and Gmail+Gemini for different jobs.
Superhuman is a polished, fast client. If you are leaving — because of the $40/mo Business price post-Grammarly acquisition, because you are still writing every email yourself, or because the speed paradigm has hit its ceiling — here is an honest map of the real alternatives, and the one that attacks the writing itself is Agentys ($16.99/mo, automatic drafting), with Shortwave (AI client) and Gmail+Gemini (free in Workspace) covering different jobs.
Start Here: What Superhuman Gets Genuinely Right
Superhuman earned its reputation. The keyboard-first design is built for speed — load times are sub-100ms, search results surface as you type, and the split-inbox triaging workflow is elegant enough that many users describe the product as the first time email felt like a tool rather than a burden. Features like Snippets (reusable reply blocks), send-later scheduling, and the read-receipt layer that shows exactly when a message was opened are genuinely well-executed. The 2022-era Superhuman that its early adopters fell for was a genuine step-change in email UX.
The AI layer that has been layered on top since 2023 — Instant Reply for short one-click suggestions, Write with AI for full drafts from a prompt, Auto-Summarize for condensing long threads — works competently inside the interface. For professionals who process 20–40 emails a day and want a faster, more focused experience than stock Gmail or Outlook, Superhuman at its price still has a defensible case. This article is not written to convince satisfied Superhuman users to leave. It is written for people who have already decided the product no longer fits — and want to think clearly about the real alternatives before they cancel.
One context item that matters for this decision: Grammarly announced the acquisition of Superhuman in July 2025 and closed the deal in October 2025 at a reported ~$825M, with Rahul Vohra remaining CEO (Wikipedia, Superhuman email client). The acquisition has not produced major product changes so far, but it did coincide with a pricing restructuring that is worth understanding before you compare costs.
The Real Reasons People Churn from Superhuman
Price, restructured post-Grammarly. Superhuman's current pricing, confirmed from superhuman.com/plans as of mid-2026, separates email from other tools. Email access — the core product most users came for — is on the Business plan at $40/month ($33/month billed annually). The $30/month Starter tier does not include email. This is the detail that catches people by surprise when they review their billing. At $40/month, that is $480/year for a fast, keyboard-optimized email client with an assistive AI layer. For solo operators, freelancers, and small-team budget reviews, that number has become harder to defend — particularly against tools that cost half as much or come bundled with the productivity suite a company already pays for.
'I'm still writing every email myself.' This is the most underappreciated churn reason, and arguably the most legitimate. Superhuman's AI features — Write with AI, Instant Reply — are what the industry calls assistive: you open the email, invoke the command, review the output, edit as needed, and click send. The AI accelerates the writing step, but you are still the one opening each message and managing the queue. Professionals who expected AI to meaningfully reduce inbox time often find themselves spending the same 60–90 minutes per day on email, just with snappier drafts. McKinsey Global Institute (2012) put the email share of the average knowledge worker's week at 28% — over a decade later, faster drafts have not bent that curve.
The Grammarly acquisition created genuine uncertainty. When a $825M acquisition closes, product roadmaps shift. Some power users have reduced their dependency on Superhuman proactively, hedging against feature changes, price adjustments, or integration pivots that tend to follow large acquisitions. This is not a criticism of the deal — Grammarly has substantial resources and Vohra has every reason to stay focused — but the rational response to any platform dependency risk is to evaluate alternatives while the evaluation is not urgent.
Cognitive interruption, not typing speed, is the actual bottleneck. Gloria Mark's research at UC Irvine puts the average refocus time after a workplace interruption at 23 minutes and 15 seconds (*Attention Span*, 2023). Superhuman reduces how long each email takes to compose. It does not remove the interruption itself. A user checking email six times a day on Superhuman recovers focus faster per message — but the structural cost of the interruption pattern is unchanged. Users who have internalized this distinction often realize they need a different category of tool, not a faster version of the same one.
Alternatives Mapped to Your Actual Need
The exit from Superhuman sends people to very different destinations depending on why they are leaving. Mapping the alternative to the actual pain point, not just the category, is what prevents ending up with a tool that solves the wrong problem.
Need: automatic drafting, keep Gmail or Outlook as-is. Agentys ($16.99/mo Starter, 7-day free trial) connects via standard OAuth and processes your inbox automatically. By the time you open your email, every incoming message has been sorted into Action, Info, or Noise categories — and every Action-category message already has a complete draft reply sitting in your Drafts folder. The drafts are written in the voice Agentys learns from your sent mail: your sentence length, your sign-off style, the formality register you hold with each specific contact. At $21 less per month than Superhuman Business, the cost comparison is straightforward. More important is the structural shift: Agentys writes the complete draft for you, so you review and send rather than compose from scratch while you are already at your desk.
Need: a smarter, faster email client. Shortwave ($24/seat/month Business, billed annually; no free tier, 14-day trial) rebuilds the Gmail client entirely around AI. If the reason you chose Superhuman was primarily the interface redesign — fast, clean, keyboard-accessible — and you want that plus more context-aware AI drafting, Shortwave is a close fit for that client-replacement need. It connects to Gmail via OAuth, groups threads by topic automatically, and generates drafts from short instructions. But that is a different job from Agentys's: you are choosing a new client to operate, not handing the drafting off to run automatically. The migration cost is real — you leave Gmail's native interface and ask your workflow to adapt — whereas Agentys leaves your client untouched and simply has the drafts waiting.
Need: AI email assistance for free, already paying for Google Workspace. Gmail's Gemini features — Help Me Write on paid Workspace plans, Smart Compose on free accounts — are already available to most professionals reading this. If you were paying Superhuman $40/month primarily for AI drafting assistance and your email volume is under 30 messages per day, Gemini in Gmail is a legitimate downgrade path rather than a degraded one. The drafts require more prompting per email and the tone is more generic, but the cost delta ($40/month saved) is real and immediate.
Agentys: What the Automatic Model Actually Looks Like in Practice
Because Agentys is structurally the least familiar alternative for former Superhuman users, it deserves a more granular description. Superhuman users are used to a client they actively control — Agentys does the drafting for you. The setup is a standard OAuth authorization (the same permission flow you use to connect any trusted app to Gmail or Outlook). No browser extension, no app installation, no new interface to navigate. Once connected, Agentys runs a processing cycle automatically, and three things happen to your inbox before you sit down to review.
First, every incoming message is categorized. The categories are Action (requires a reply or decision from you), Info (read-only, FYI), and Noise (newsletters, automated notifications, low-signal updates). The categorization is not a filter in the SaneBox sense — messages stay in your existing inbox structure and are labeled, not moved to opaque third-party folders. You see the full inbox; the signal is surfaced, not hidden.
Second, every Action-category message gets a complete draft reply deposited in your Gmail or Outlook Drafts folder. The draft is written in the voice Agentys has built from studying your sent mail. Voice learning at this level of specificity is what separates the tool from generic AI drafting: it does not produce a professional but impersonal response. It attempts to replicate how you write to that specific person — the vocabulary you reach for, the length you typically hold, whether you open with pleasantries or go straight to business. Most users report the drafts require light editing by day two or three; the first day's output is functional but not yet calibrated.
Third, a briefing gives you the priority-ordered Action list. You open your inbox and see the queue for the day: drafts waiting for approval, messages that require your judgment (no draft was generated for genuinely ambiguous or sensitive threads), and everything that has been categorized as Info or Noise. The total inbox time for a typical day shifts from 60–90 minutes of active processing to 20–30 minutes of review and approval. That is the structural difference Superhuman's model cannot reach, because Superhuman still requires you to open every message before any AI assistance begins.
One Honest Limitation of Agentys
Agentys is the right structural answer for a specific kind of inbox problem — high volume, consistent relationship types, recurring reply patterns. It is not the right tool for every professional, and it is worth being clear about where it falls short.
The automatic batch model has an inherent latency. If you receive a genuinely urgent message and need to respond within minutes, Agentys's processing cycle does not help you — the draft is ready for your review, not the instant a message lands. The tool is designed for the common case — email that can wait a little while, drafted automatically for you to review — not for on-call incident management or real-time crisis communication. Professionals whose email genuinely does not permit a review-and-send batch (emergency services, on-call engineering, deal-flow-dependent roles in live negotiations) need a tool that assists in real time. Agentys is not that tool.
The voice learning model also requires calibration time. The drafts on day one are functional but generic — they will not yet reflect how you write to specific contacts. The calibration improves materially by day two or three, and most users find the outputs solidly usable by the end of the 7-day trial. But users who evaluate the product in the first 24 hours and abandon it before the model has had time to learn will not see what the tool is actually capable of.

Superhuman built a fast, polished client, and that speed is real for professionals who use email as a primary work surface. But speed is a different thing from removing the writing — and if you are leaving because you are still writing every email yourself, or because the Grammarly acquisition introduced uncertainty, or because $480/year has become hard to justify for an assistive tool, the alternatives above address those specific problems. Agentys addresses the core structural issue: the complete reply written for you automatically, so you review and send rather than compose from scratch. At $16.99/month with a 7-day trial, the cost of finding out is low.
