About Lethe

Lethe is the switchboard between you and every AI: one understanding of you, built from your own words and owned by you, that Claude, Cursor and any MCP client read with your permission. Every claim cites its line; every read is on the record. Free beta. Lethe, connect once, every AI opens knowing you . Import what you already have, let Lethe understand it with the receipts attached, and every AI you connect reads the same you.

About Riley

Riley is an AI writing assistant for founders, personal brands, and marketing teams. Create on-brand social posts, blog posts, and newsletters from a short prompt. Riley remembers your voice, business, and audience, then turns a one-line prompt into on-brand posts, blogs, and newsletters, without rebuilding context or spending hours rewriting. Riley keeps your context, content, and workflow in one dashboard, so you can move from idea to on-brand published post without starting from scratch. Riley brings that context into every draft, so you can start with the idea instead of rebuilding the prompt.
