YAFOY Memory: Your Personal Archive, Explained

"Didn't you write that down somewhere?"

You did. The contractor's quote, the restaurant a friend recommended, the instructions IT sent for the new printer. Each one was saved, carefully, months ago. The problem isn't that the information is gone. It's that you can't remember where you put it, or what words it used.

This is the problem every "ask your notes" tool is trying to solve, and in 2026 there are many of them. They differ less in how clever their AI is than in a quieter design choice: what the AI is allowed to look at. That choice decides how useful the answers are, and how much you can trust them.

An AI that can see everything — your whole workspace, your connected apps, the open web — can answer almost any question. The catch is provenance. Unless the tool cites its sources, you can't always tell whether an answer came from your contractor's quote, a similar quote in someone else's document, or a web page.

An AI that can see only a small, deliberate collection answers fewer questions, but every answer can only come from something you chose to keep. For personal information like quotes, codes, instructions and promises, that trade usually favors the smaller scope.

With that in mind, here is how the main options compare.

Notion AI can search the pages you have access to in your workspace, connected apps such as Slack and Google Drive, and the web, which workspace owners can turn off. It's included in the Business plan ($20 per member), while Free and Plus get a limited number of complimentary responses.

Best for: teams whose knowledge already lives in Notion. Trade-off: broad scope, and a workspace you have to build first.

Google's research notebook, renamed Gemini Notebook in 2026, answers questions based on the sources you add, with inline citations: PDFs, Google Docs, web pages, YouTube videos, audio and more. It now also offers research tools that can pull in new sources from the web. The free plan allows 100 notebooks of up to 50 sources each, with higher limits on Google AI plans.

Best for: studying, research and reading-heavy projects. Trade-off: it's built around documents you upload into notebooks, not the small, scattered details of daily life.

Mem pitches "AI notes" that organize themselves, with deep search, a web clipper, voice mode and, on paid plans, connections to Gmail and Slack. Its free plan is capped at 25 AI messages and 25 new notes, and paid plans start at $9 a month. Check Mem's pricing page for current plans.

Best for: heavy note-takers who want an AI-native notebook.

Evernote's AI Assistant (powered by OpenAI) can answer questions and summarize, and its semantic search uses Evernote's own models. Both can read text in notes and attachments, including PDFs and images. AI is on by default and can be turned off. The free plan's 50-note limit makes it hard to start a new archive there without paying.

Best for: long-time Evernote users with years of notes.

Apple Notes search already finds text inside scanned documents and images. With iOS 27, Apple added Siri AI search that can find and search inside notes on supported devices (iPhone 15 Pro or later). It's free, but it's a search assistant across your device rather than a dedicated archive you curate.

YAFOY's Memory tab, the one with the brain icon, takes the narrow-scope approach on purpose. It holds exactly two things:

1. Everything you saved with Add: photos, screenshots, documents, links, notes and voice notes.
2. Chat messages you marked "Remember this" with the brain icon. See how that works.

Nothing else gets in by itself. Memory doesn't absorb your whole inbox, your other apps or the web.

Each saved item appears as an expandable row showing what YAFOY worked out when you saved it: a title, a summary, the source, and the people and topics involved. So instead of "IMG_4471," you see "Contractor quote: kitchen tiles, $3,200, valid until March."

There are two ways to find things:

• Search when you know what you're looking for: it matches across text, filenames, titles, people and topics.
• Ask when you want an answer: How much was the contractor's quote for the tiles? Memory answers strictly from what you saved, not from your whole inbox and not from the web.

And because adding is the other half of the habit, tapping + on the Memory tab goes straight to Add. See everything Add can capture.
