Equerry alternatives

Most AI tools remember only what happens inside themselves. Equerry is a personal assistant: you forward or CC the emails that matter, drop in a PDF, dictate a voice memo, or save a note — and it remembers across all of them, with the source attached. Here is how it compares to the tools you might be replacing or pairing it with.

• Notion AI alternative When you want memory across every tool — emails, PDFs, notes, voice memos — not just inside your Notion pages.

Four questions worth asking before you switch

Most comparisons rank tools. That is the wrong shape, because the honest answer changes with what you need remembered. These four questions separate the options faster than any feature table:

• What can it remember across? Nearly everything remembers its own surface — one app's chats, or one app's notes — and reaches further only by taking a whole account. Far fewer can answer a question that spans the email thread, the contract, and the note you dictated after the call. If your work lives in one tool, one app's memory is enough. If it does not, no amount of capacity fixes the gap.
• How does it get your material? Two shapes exist, and they are not close. Some tools ask you to connect a whole account — your mailbox, your drive — and take it from there. Others only ever see what you deliberately hand over, thread by thread. The first is less work; the second is the one you can explain to a client.
• Can you see what it kept? Ask to be shown the list. A tool that can display every fact it has stored about your work, in one place, is a different proposition from one that summarises confidently and shows nothing underneath. Memory you cannot inspect is memory you cannot correct.
• Does it show its source? For client work this is the one that matters. An answer you can trace to the exact email or note it came from is checkable before you repeat it in a room. An answer without a source has to be taken on trust, and trust is the thing you are actually buying.

Equerry answers those four as: across everything you share with it; only what you hand it; yes, listed and deletable one by one; and yes, with the source shown when it draws on your notes, emails or the web. Whether that is worth switching for depends entirely on which of the four you were stuck on.

Head-to-head comparisons

If you are weighing a specific tool rather than the category, these go into detail — what each one genuinely does better, and where the line falls:

• Which AI has the best memory?The four measures people mean by "best", and which assistant wins on each.
• A ChatGPT alternative with memoryWhat ChatGPT's memory does and does not reach, and when that becomes the problem.
• ChatGPT memory vs Claude memoryTwo different designs — one summarises, one keeps an inspectable list.
• Memory that spans your toolsWhy single-app memory keeps failing the question you actually asked.
