Slashy

Slashy is an AI-native email client built by Slashy, Inc. that replaces the manual grind of inbox management with a persistent memory system, tone-matched draft generation, and automated workflows. It works on top of existing email providers like Gmail and Outlook, so users don't need to migrate away from their current setup. The product targets busy founders, investors, and professionals who receive high email volume and need to respond quickly without sacrificing voice or context.

What It Is

Slashy sits in the category of AI email clients — a step beyond AI-assisted writing plugins. Rather than bolting a language model onto a standard inbox, Slashy builds a persistent model of each user's tone, VIPs, and routines from their full inbox history. It then uses that model to draft replies, auto-label incoming mail, trigger automations, and manage calendar actions — all without requiring the user to prompt it from scratch each time.

How the Memory System Works

The core differentiator Slashy highlights is its self-improving memory layer. Instead of injecting a handful of recent sent emails into a prompt, Slashy claims to build a real model of the user's communication patterns over time. The memory stores things like preferred sign-offs, recurring contacts, scheduled habits (e.g., "sends investor updates on Mondays"), and active to-dos. Every reply, edit, and correction the user makes feeds back into this model, making drafts progressively more accurate to the user's actual style.

Key Capabilities

• AI draft generation: Drafts replies in the user's tone, ready to send in one click
• Inline AI assistant: Highlight any text to rewrite, shorten, or change tone on the fly
• Auto-labeling: Categorizes every email with custom AI labels; important emails surface automatically
• Automations: Trigger AI workflows on incoming email, before/after calendar events, on email opens, or on a cron schedule
• Calendar integration: Manage meetings, share availability, and book events directly from the inbox; AI reads the calendar to inform draft context
• Open tracking: See when recipients open emails, on which device, and how many times
• Unified inbox: All connected accounts in one prioritized view
• Snippets: Save and reuse common replies with a single keystroke
• iMessage and Slack access: Chat with Slashy via iMessage or Slack to triage email and manage calendar from anywhere

Security and Compliance Posture

Slashy publishes a detailed security page and holds SOC 2 Type II certification. Data is encrypted in transit with TLS 1.2+ and at rest with AES-256. The company states that customer data is never used to train AI models and that its AI providers guarantee zero data retention. Additional enterprise-grade controls include CASA Tier 2 certification, monthly independent penetration tests, SCIM/SSO support, audit logs, and the ability to delete all data within 24 hours on request. HIPAA-compliant handling is available at the enterprise tier.

Integrations and Platform Reach

Slashy connects to Gmail and Outlook without requiring migration. On the productivity side, it integrates with Zoom and Google Meet for automatic conference link attachment, HubSpot and Attio for CRM-aware drafting and routing, and Granola for pulling meeting notes into email threads. The MCP server lets external AI agents — including Claude and ChatGPT — read and act on the inbox. Mobile access is handled through iMessage and Slack rather than a dedicated mobile app, per the homepage FAQ.

Audience and Positioning

Slashy positions itself against Superhuman and Gemini in Gmail, publishing a feature comparison table on its pricing page. The company's manifesto frames the product around reclaiming the time professionals spend on repetitive email tasks. Testimonials on the homepage are attributed to named founders and investors, including a Redpoint investor and several startup founders, though these are vendor-published claims. The enterprise offering targets teams of 50 or more and adds dedicated account management, customized onboarding, and bespoke security controls.
