Posted by u/Tanto_Faz_123 on Reddit, a screen recording shows that Telegram is developing the spoiler-hiding format but hasn’t made it available to the public just yet. It will be hidden in the long-press styling menu when selecting text, and will pixelate the text behind a fuzzy animation similar to Apple’s invisible ink effect on iMessage.
The text will remain hidden until the recipient taps on the view button, though it doesn’t actually say “spoiler” or anything of the sort, so you’ll have to make sure every person you’re sending the spoiler to is familiarised with the feature first. It’s not clear whether this feature will be extended to one-on-one and group chats, or be exclusively available to channels. The date for the public stable rollout hasn’t been revealed, though we can assume that when it does launch, it will be available for all of Telegram’s apps — iOS, Android, desktop — as it usually releases new features to all platforms simultaneously.
