saidosi
Read full descriptionHide full description
saidosi is an AI notes app. Tell it what you want to remember, or have it look through your notes to find answers and organize what you've saved. An idea from work, a thought from a book, a shop you found on a trip—even a single sentence is enough to start a note, without picking a title or folder first. When more details come to mind later, just say the word and saidosi will add them to the earlier note. When you need something back, ask with whatever you remember: “What was the name of that hotel I stayed at in Hangzhou last year?” saidosi looks through your notes to find the answer. If you'd like to share recommendations with a friend, have it pull together a list of restaurants and places you stayed from that trip. As your notes grow, you don't have to open, copy, and move them one by one. Tell saidosi what you need—like bringing together scattered notes from the same project—and let it find and organize them for you. Every note is ready to open and read anytime. Edit the text yourself, or ask saidosi to make changes while you read. Membership and subscriptions All accounts can use Flash and Pro models. New users receive a one-time free allowance.
