As answered by people managing Equerry.app and Supermemory.
Equerry.app's answer
Nothing gets into your assistant unless you send it. There is no inbox access: you save notes, voice memos, photos and PDFs, or forward and CC the email threads that matter, and your equerry works only from that. Your notes, emails, PDFs and voice memos finally talk to each other, and every answer opens the original it came from. You can see every fact it kept, per note, and delete any of it. Your originals stay in your iCloud, not on our server. Scheduled briefs keep you ready for what's next, built from what you chose to save, with sources.
Equerry.app's answer
Control and provenance. CC your assistant and it reads the thread, not your inbox. Most assistants either start from a blank chat or ask for access to a whole mailbox or account; Equerry works only from what you send it, across every tool you use, so your working life is not tied to one ecosystem. Every answer opens the original note, email or file it came from, so you can check it in one tap. You can see everything it remembered, per note, and delete any of it. Your originals stay in your iCloud. And it costs less than one billable hour a month.
Equerry.app's answer
Senior, client-facing professionals on iPhone: consulting partners, advisors, fractional executives and other operators who run several client engagements at once. They already pay for premium productivity tools and want an assistant that holds the context for them: prepared for the next meeting, on top of client follow-ups, and able to find the detail from an old email, PDF or voice memo without digging for it, with the source attached.
