Slashy’s AI writes emails that sound like you by learning from your email history, explicit preferences, and draft feedback. You can accelerate this by telling the agent exactly how you want it to write.Documentation Index

Setting Writing Memories
Open the agent sidebar (p a) and tell it your preferences:
- “Remember: I write short, direct emails. Never use ‘I hope this finds you well.’ Keep it under 3 sentences.”
- “Remember: I sign off with just my first name, no ‘Best’ or ‘Regards.’”
- “Remember: formal tone for investors, casual for my team.”
- “Remember: never use exclamation marks.”

Memory Types
| Type | What It Does | Example |
|---|---|---|
| About Me | Rules for all emails | ”I prefer bullet points over paragraphs” |
| About Entity | Per-contact/company rules | ”When emailing Sequoia, always CC sarah@mycompany.com” |
| Activity-anchored | Rules for specific activities | ”When scheduling, offer 3 time slots and include my Zoom link” |
Persona Detection
During setup, Slashy analyzes your sent emails to detect your persona, greeting style, and signature. Edit these anytime in Settings > Account.
Training by Deleting Bad Drafts
Every dismissed draft teaches the agent what not to do. Every edit before sending teaches it what you prefer. The learning is context-specific — editing a sales reply improves sales drafts, not meeting confirmations. First week advice: Actively dismiss bad drafts and edit acceptable ones. Most users see significant improvement within 10-15 interactions.Direct Feedback
Beyond deleting drafts, give feedback through the sidebar:- “That last draft was too formal. I talk to Mike like a friend.”
- “When I reply to support tickets, use bullet points and be concise.”
Per-Contact Preferences
- “Remember: when emailing anyone @bigclient.com, use a formal tone with my full signature.”
- “Remember: Mike prefers short emails. Keep replies under 2 sentences.”
