An SNS where both reading and writing take just 10 seconds 【Satto Me】 In a world overflowing with information, we face daily exhaustion—so much so that terms like "SNS fatigue" and "digital detox" have emerged. To lighten this burden, we developed 【Satto Me】, an ultra-short-form SNS (max 60 characters) designed for quick reading and quick writing. ■ Ultra-short-form SNS (Max 60 characters) The length is just right—perfect for casually posting anything from "daily musings" to "thoughts about your favorite idol"! For example: "It's getting hotter lately... maybe I'll stop by the convenience store on my way home and grab some ice cream!" That’s 40 characters; with 20 more to spare, you can actually write quite a bit. ■ Replies limited to "24 hours" after posting Free yourself from the stress of being hounded by notifications for old posts! Once 24 hours have passed since the post, no further replies will be received. ■ Notifications categorized by action so nothing gets missed It’s easy to miss things when you’re flooded with follows, reactions, and replies. Satto Me organizes notifications by action type, making it harder to overlook important updates. ■ Share feelings with "Reactions" instead of just "Likes" A reaction feature that lets you attach various emojis instead of a standard "Like"! Quickly convey feelings that a simple "Like" can't express. ■ View posts filtered by "Reaction type" Reactions aren't just for sharing feelings in the moment; you can also review your posts later based on the reactions they received! ■ Satto Me's Key Feature ①: "Satto Tags" Traditional hashtags have downsides due to their excessive freedom—for instance, users of "#SattoMe" and "#Sattome" couldn't interact with each other. "Satto Tags" aims to unify tags so you never miss out on valuable topics or interactions! ■ Satto-Me Key Feature #2: "Tag Filters" Select tags that interest you and switch between views on your timeline! We offer a wide variety of unique tags—from staples like "Anime" and "Gourmet" to trending topics like "VTubers" and "Minecraft," and even niche ones like "Oogiri" (comedy prompts) and "Morse Code"! ■ Satto-Me Key Feature #3: "Multi-Column View" (PC Only) With the multi-column feature, you can check multiple timelines simultaneously without switching screens! It may be a small-scale social network right now, but once the posts start rolling in, this feature is sure to become a game-changer! ■ Only "You" Can See Your Following/Followers For those who feel embarrassed or simply don't want others to see their list of people they follow or their followers, Satto-Me ensures that only *you* can view this information. ■ How to Enjoy Satto-Me (Our Values) "Respect for Ultra-Short Posts": Since character counts are limited, let's strive for polite expressions that show consideration for others. "Diverse Values": Treat people with different opinions or backgrounds with respect. "Positive Empathy": Prioritize constructive opinions and empathy over aggressive rebuttals. *Satto-Me prohibits use by individuals under the age of 13.
