How this report works
Assistants are ranked by their Memory score. The test also checks that you can see and delete what it remembers.
How to choose
- Tell it your preferences once, plainly, and check a week later whether it still uses them.
- Make sure you can see and delete what it keeps. That is part of the test; the product facts on its page say whether memory can be turned off.
- Correct it when you change your mind. The best ones use the update and drop the old preference.
What users say
Instinct giving contextual product updates is one of the coolest things I've ever seen
Open sourceInstinct is a new startup which launched recently and it does some very nice things on the memory side which gives that feel of it being a real assistant rather than a chatbot.
