Slashy vs Lindy 2026: Email Client vs AI Teammate

We rewrote this page on October 6, 2026, because our first version described a product Lindy no longer sells. In May, Lindy was a workflow canvas you assembled yourself. Its homepage now calls it "Not an AI tool. A coworker.", and its pricing page lists inbox management and "Drafts replies in your voice" on every plan. Every Lindy claim below was read on Lindy's own site that day and is linked. We build Slashy, so weigh our take accordingly.

Is Lindy an email client?

No. You still read and write your mail in Gmail or wherever it lives. What Lindy adds is an assistant that works across your tools and also touches your inbox.

Lindy's homepage says it is "wherever you work": in Slack threads, over iMessage, and "in your inbox", where, in its words, it "drafts, schedules, and replies without leaving your email." It connects to Gmail, Slack, Notion, HubSpot and "1,000+ more" tools, supports MCP, and records and summarizes meetings. The unit of work is a request you hand it ("reconcile this ledger", "prep me for Thursday"), and email is one place those requests land.

Slashy is the other shape. It is the inbox itself, so everything the AI does happens on the thread you are reading: the draft is waiting when you open it, the label was applied before you arrived, and the calendar sits beside the conversation.

What is the difference between Slashy and Lindy?

Lindy is broad and sits beside your tools. Slashy is narrow and replaces your mail client. That one difference explains most of the table further down.

Because Lindy is not your inbox, it can do things a mail client never would: answer a question in Slack with data from HubSpot, record a call and turn it into tasks, or run a scheduled routine across several apps. We do not do any of that, and if that is the job you need done, Lindy is the better tool.

Because Slashy is your inbox, it can do things an outside assistant has a harder time with. Mail is sorted into seven labels before you open it, open tracking shows when and on which device a message was read, and ghost detection flags threads that went quiet so the follow-up goes out on time. Each of those lives in the mail view you already work in, rather than in a chat window you have to remember to ask.

Can both draft emails in my voice?

Yes. Lindy's pricing page lists "Drafts replies in your voice" on every plan. Slashy drafts in your tone from a memory that learns from the mail you send.

On Slashy's own usage data, the share of drafts a new user sends without editing climbs from about 30% on day one to over 80% by day 30. We have no equivalent figure for Lindy, and Lindy does not publish one, so we do not claim one is better. The practical difference is where the draft appears. In Slashy it is attached to the thread, next to that contact's calendar and follow-up state. In Lindy, it comes back through Slack, iMessage or your inbox in response to a request, and, per its pricing page, "anything with outside impact waits for approval."

"The agent is unbelievable. The memory system actually works. It actually gets me."

Suhail, Founder of Lunabill

How do the memory systems compare?

Both keep memory, built for different jobs. Lindy's is broad and editable. Slashy's is narrow and tuned to email.

Lindy says it "learns everything about you, and it all lives in plain files": you can open the memory folder, read what it remembers and change it like a document. That is transparent and works across every tool Lindy touches, such as a note that an account renewal is this quarter's priority. Slashy's memory learns your voice, recipients, response timing and scheduling habits from real inbox activity, and the same memory drives drafting, triage, follow-up timing and the calendar. You cannot open it as a file, and it only knows email. If you want to read and edit what your assistant knows, that favors Lindy.

How long does setup take?

Both take minutes now. We used to write that Lindy needed workflows built before it was useful, and that is out of date. Lindy's pricing page says setup takes about two minutes, and its homepage says an admin installs it in Slack and everyone else links with one tap.

Slashy connects through your Google or Microsoft sign-in, and drafts and labels start working on the first session. The difference after setup is the work you do next. Lindy gets better as you give it tasks and save skills for the team. Slashy gets better as you use the inbox, with no tasks to assign.

Slashy vs Lindy comparison table

Sources: Lindy pricing and Lindy homepage, both read October 6, 2026; Slashy pricing.

How do the prices compare?

Slashy is $30 per user per month, or $25 billed annually ($300 a year). That covers everything above, with a 7-day trial that needs a card. There is no free plan.

Lindy has a free tier and then charges by usage. Per its pricing page, Free gives "$50 in credits" that last 7 days with no card. Team starts at $29.99 a month per active user for 3,000 credits, pooled across the team, and the page lists packages from 3,000 credits at $29.99 up to 1,750,000 credits at $9,999.50, with top-ups at $10 per 1,000 credits. Credits are metered by the work Lindy does: the page puts everyday asks, including drafting a reply, at 2 to 250 credits and a day's support-queue triage at 250 to 1,000. Enterprise is custom and adds HIPAA compliance with a signed BAA, SSO and SCIM, and audit logs.

The shapes differ. Slashy's cost is flat per seat, so you can predict it. Lindy's depends on how much work you give it, which is cheaper if you ask for little and harder to forecast if you ask for a lot.

Which is more secure?

It depends on what you need to show a reviewer. Slashy is SOC 2 Type II and CASA Tier 2 certified, encrypts data with AES-256 at rest and TLS 1.2+ in transit, does not train AI models on your data, and requires zero data retention from its AI providers. Slashy is not HIPAA certified.

Lindy lists HIPAA compliance with a signed BAA on Enterprise, which Slashy cannot offer, so a healthcare team that needs a BAA should look at Lindy. We did not review Lindy's other security documentation for this page. Read it directly if security review is a gate for you.

What to choose if

Choose Slashy if:

• Email and calendar are most of your day, and you want one client where triage, drafts, follow-ups and the calendar are already connected.
• You want a predictable per-seat price.
• You use Outlook.com or Microsoft 365 as well as Gmail.
• You want the draft waiting on the thread, not something you have to ask for.

Choose Lindy if:

• You want one assistant across Slack, meetings, your CRM and other tools, not only email.
• You want to open and edit what your assistant remembers.
• You want to try it free, or you need a signed BAA.
• You are comfortable with usage-based pricing.

Use both if you want Slashy as the place you read and answer mail, and Lindy for the work that happens outside the inbox.

If you are still comparing options, our Lindy alternatives guide puts it next to several other tools, and what an AI email agent actually does explains the triage, draft and send loop in more detail.
