"AI executive assistant" has become a real category: instead of a scheduling app you open, you just text, email or talk to an assistant and it handles the coordination. Espa AI explicitly lists Hey Noah as one of its direct alternatives, which makes this an honest head-to-head rather than a forced comparison. The short version: one is open to anyone with a card today, the other is invite-only and quiet about pricing.
Espa AI: open self-serve, built by an ex-Forethought founder
Espa AI is built by the founder of Forethought, and its pitch is flexibility of input: text it, email it, forward it a screenshot, or send a rambling voice memo, and it figures out what you need — scheduling, inbox triage, or following up on something you dropped. It writes emails matching your own tone rather than a generic template, and it's live and self-serve right now.
Price: free for 10 emails/tasks per month; Personal $19.99/mo ($239.88/yr); Pro $39.99/mo ($479.88/yr, 5 inboxes, priority support).
Channels: SMS, WhatsApp, Slack, email.
Strengths: transparent, public, self-serve pricing you can start using today; genuinely multi-channel input including screenshots and voice memos; explicit messaging around encryption and privacy controls.
Weaknesses: the free tier caps at just 10 emails/tasks a month, so you hit the paywall fast; the assistant-for-scheduling space is crowded and Espa AI doesn't name a specific edge over the field beyond input flexibility.
Hey Noah: invite-only, built specifically around executive coordination
Hey Noah frames itself more narrowly and more deliberately as an executive assistant: scheduling, follow-ups and meeting prep across email, SMS and voice, with pre-meeting briefings that pull in context and automatic meeting notes with extracted action items. It integrates with Gmail, Calendar, Zoom, Slack and Notion. The catch is access — it's currently invite-only, with sign-up gated by phone number.
Price: not published. No public tiers; access is private beta by invitation.
Channels: email, SMS, voice.
Strengths: deeper meeting-specific features — pre-meeting briefings with real context, automatic action-item extraction from notes — plus explicit time-zone and travel awareness that goes beyond simple booking.
Weaknesses: no public pricing or self-serve signup at all right now, limited public documentation on how it actually performs, and a waitlist/invite model that limits real-world adoption data.

Verdict
Pick Espa AI if you want to actually start using an AI executive assistant this week, need transparent pricing to justify the expense to yourself or a team, and like the idea of dropping in a voice memo or screenshot instead of writing everything out.
Pick Hey Noah if you can get off the waitlist, your bottleneck is specifically meeting coordination and prep rather than general inbox work, and you're already living in Gmail, Zoom, Slack and Notion where its integrations plug in directly.
Honestly, the biggest practical difference right now isn't features — it's access. Espa AI you can try in the next ten minutes; Hey Noah you can't try until they let you in. If you need something working today, that alone settles it.
