Hiring a human executive assistant costs real money and usually only makes sense once you're drowning in scheduling and email. A newer category of AI tools tries to fill that gap for founders, solo operators and busy professionals who aren't there yet: you text, email or CC an AI assistant, and it handles the back-and-forth of booking a meeting, clearing your inbox, or even calling your dentist to reschedule an appointment. None of these fully replace a human — judgment calls and sensitive situations still need one — but for the repetitive coordination work, they can save real hours. Here are 9 worth knowing about, grouped by what they actually do.
Multi-channel chief of staff
These three try to cover the whole job — calendar, email, meeting prep — not just one slice of it.
Espa AI: text, email or voice memo, built by an ex-Forethought founder
Espa AI is built by the founder of Forethought, and it shows in the pitch: you can hand it a task as a text, an email, a screenshot, or a rambling voice memo, and it works out what you actually need — scheduling, inbox triage, or following up on something you forgot about. It writes emails in your own tone rather than a generic template.
Price: free for 10 emails/tasks per month; Personal is $19.99/mo, Pro is $39.99/mo (5 inboxes, priority support).
Strengths: genuinely multi-channel input (SMS, WhatsApp, Slack, email), transparent self-serve pricing, explicit privacy/encryption messaging.
Weaknesses: the free tier caps out at just 10 emails/tasks a month, and the AI-assistant-for-scheduling category is crowded enough that the differentiation isn't always obvious at first glance.
Hey Noah: invite-only, built specifically for executive coordination
Hey Noah positions itself squarely as an executive assistant: it manages 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.
Price: not published — sign-up is by phone number, access is private beta/invite-only.
Strengths: real multi-channel conversation interface, time-zone and travel awareness, pre-meeting briefings with context baked in.
Weaknesses: no public pricing or self-serve onboarding, limited public documentation, and you need an invite to even try it.
Bond: a chief of staff that lives inside Slack
Bond skips the separate-app problem entirely by living inside Slack. It reads your email, calendar and meeting notes, works out what actually matters this week, and nags your teammates about the things they owe you — instead of you having to chase them yourself.
Price: $99/seat/month billed annually (beta pricing is currently -50%, duration of the discount unclear); Enterprise is quote-based with SOC 2 Type II, SSO and SCIM.
Strengths: no separate app to check, connects to a wide range of tools, honest framing of its value against the cost of a human chief of staff.
Weaknesses: the "10+ hours a week saved" claim isn't independently verifiable, the API is still "coming soon," and $99/seat/month is a real commitment for an early-stage product.
Email-focused assistants
If scheduling isn't your bottleneck and your inbox is, these three are built specifically around email.
Deck AI: an assistant with its own email address, not access to yours
Deck AI takes a deliberately narrow approach: you CC it on a thread or forward it a task, and it replies — without ever getting a password or OAuth access to your actual inbox. It only replies to the person who contacted it, never to everyone else on the thread.
Price: free for 20 messages/day and one email address; Pro is $29.99/mo for unlimited messages and automations (14-day free trial); Enterprise is quote-based with SSO/SAML.
Strengths: zero direct inbox access is a real privacy advantage, SOC 2 certified and GDPR-compliant, generous free tier for testing.
Weaknesses: $29.99/mo adds another recurring cost, it can't draft-and-send to third parties without a human relay, and the AI-email-assistant space is already crowded.
Airo Mail: tells you exactly what to do with each email
Airo Mail sits on top of Gmail and, instead of just sorting your inbox, tells you the concrete next action for each message — reply, pay, schedule, or move a deal forward. It's built with solo-founder workflows in mind: package tracking, travel itineraries, even turning a bug report into a pull request.
Price: 14-day free trial, no card required; Pro is $25/mo; Max is $100/mo (6x the AI credits); Team is quote-based with SSO/SOC2/HIPAA.
Strengths: action-oriented triage instead of generic sorting, unified inbox for up to 10 Gmail accounts, CASA Tier 2 security certification.
Weaknesses: Gmail-only — no Outlook or other providers — and $25 to $100/month is a real budget for what's fundamentally an email client.
AI Emaily: an autopilot that actually sends, not just suggests
AI Emaily's Autopilot mode genuinely acts — it summarizes, drafts and sends — rather than just proposing a reply for you to approve. Its "Living Brief" keeps persistent context per contact so replies stay personalized, and it runs on every email provider and device.
Price: 7-day free trial; Pro is $19.99-$29.99/mo; Autopilot is $34.99-$51.99/mo; Team is roughly $20-22/seat/mo (3-seat minimum).
Strengths: Autopilot actually completes the loop, AI-powered inbox search with sourced answers, multi-touch follow-ups that stop automatically once someone replies.
Weaknesses: a credit-based system that heavy users need to budget carefully, trusting an AI agent to actually send email requires real confidence, and Team pricing needs 3 seats minimum.
Scheduling and phone-focused assistants
The last three narrow the job down even further — to booking meetings, or to actually making and taking phone calls.
Vela: for meetings too complex for a booking link
Vela handles the messy back-and-forth of scheduling across email, text, WhatsApp, Slack or Teams — finding a time that works across time zones and multiple participants, instead of you doing it manually. It's built for complex, multi-party coordination rather than simple 1-on-1 booking links.
Price: no public pricing — you need to ask the vendor directly.
Strengths: coordinates across six different channels, handles calendar conflicts and follow-ups automatically, built for genuinely complex multi-party meetings.
Weaknesses: no public pricing, and for the simple "here's my booking link" case, Calendly or Reclaim.ai already do the job — Vela's value is really about complexity, not convenience.
Betula: a real phone number that answers for you
Betula gives you a dedicated phone number to hand out instead of your own — it answers calls and texts 24/7, books appointments, sends reminders, and gives you a daily briefing, functioning like a receptionist you never had to hire.
Price: not published — you'd need to check directly with the vendor.
Strengths: answers calls and texts around the clock, books appointments and sends reminders, remembers context from previous exchanges.
Weaknesses: no public pricing found, few independent reviews available, and a JavaScript-heavy site that's hard to audit before signing up.
Asmi AI: makes the phone call so you don't have to
Asmi AI flips the direction: instead of answering calls for you, it makes them. Tell it to call the dentist, the plumber or your bank, and it dials, navigates the automated phone menu, waits on hold, and texts you the result — built on Gemini, Twilio and ElevenLabs.
Price: quote-based, not published — you need to try it directly to learn the cost.
Strengths: makes real phone calls rather than just sending reminders, navigates IVR menus and hold queues on your behalf, notifies you by iMessage/WhatsApp once the task is done.
Weaknesses: no published pricing, no information on the founding team or funding, and a site that's hard to verify independently before you hand it a task.

None of these tools are a full replacement for a human assistant, and several are still early — invite-only, opaque on pricing, or thin on independent reviews. But if your actual bottleneck is scheduling coordination, inbox triage, or the dread of calling customer service, there's now a real, if young, category of tools built specifically to take that off your plate.
