Prio vs Martin: AI assistants compared for founders
Last updated May 6, 2026
The verdict
Martin AI is an AI personal assistant designed around your phone — text it on iMessage or SMS the way you'd text an EA, and it handles reminders, scheduling, research, and quick tasks. The pitch is great: zero new app to learn, no dashboard to log into. For people who genuinely live in iMessage and want a low-friction assistant for everyday life admin, Martin is well-built. Prio is broader and built for founders specifically. Same chat metaphor, but with a real dashboard for inspecting what the assistant is doing, an approval queue you can audit, deeper integrations (Gmail, Calendar, Slack, Notion, GitHub, Attio), proactive insights (anticipation, calendar hygiene, autonomy graduation), and a daily briefing engine. If you want a personal life assistant in your texts, Martin is the right shape. If you want a full chief of staff that runs your inbox, calendar, CRM, and standups, Prio is the right tool.
Feature comparison
| Feature | Prio | Martin | Edge |
|---|---|---|---|
| Primary interface | Chat-first web app with iMessage/SMS, Slack, Telegram, Discord, Teams, and WhatsApp as additional channels. Native iOS app with VoIP/CallKit ringing for urgent items | iMessage and SMS native. No web dashboard — the conversation IS the product. Designed to feel like texting a human EA | |
| Email triage | Full Gmail integration: AI triage (action / fyi / delegate / archive), auto-archive of newsletters, draft composition with approval gates, follow-up tracking, autonomous scheduling negotiations | Limited email handling. Best at extracting tasks from forwarded emails. Not a triage product | |
| Calendar management | Google Calendar + Outlook with smart scheduling rules, travel buffers, location preferences, ghost-meeting detection, and back-and-forth scheduling negotiation by email | Calendar reads + event creation by text. Less depth on rules and recurring patterns | |
| Approval queue | Visible pending-actions panel with batch approve/reject. Every outbound email, calendar event, and CRM update is auditable before it ships | Confirmations happen inline in the text thread. No dashboard for inspecting historical actions | |
| Integrations | Gmail, Google Calendar, Drive, Contacts, Slack, Notion, GitHub, Attio CRM, LinkedIn, Outlook, OneDrive, Granola, MCP servers, Microsoft Graph discovery | Calendar + reminders, basic web search. Smaller integration surface | |
| Proactive insights | Anticipation engine (birthdays, board prep, contract renewals, key meetings), calendar hygiene (ghost recurring events), multi-source fusion, year-over-year recall ('last year you sent flowers from X'), autonomy graduation | Reminders + nudges. Not a full anticipation pipeline | |
| Daily briefing | AI-generated morning + evening briefings delivered via Slack DM, push, email, or iMessage with calendar, tasks, weather, top emails | Morning text recap available. Less multi-channel | |
| Voice | Browser voice agent (talk to Prio in-app), inbound phone agent (Prio answers your calls), P0 ringer (Prio rings YOU on your iPhone via VoIP for urgent items) | Voice memos parsed into tasks. No two-way voice agent | |
| Onboarding friction | Sign up → connect Gmail/Calendar → ~5 min to first useful triage. Web onboarding required | Add a contact, send a text, you're live. Lowest possible activation cost |
