Essentially, if a user has shared their Telegram screen/taken a screenshot and used spoilers to hide certain information, this tool can help reveal said info. Usually, a spoiler is only revealed on tapping the direct message but in some parts of the MacOS Telegram client, it works by the last message in the chat list and pinned message using a fallback that turns text into pseudo-Braille characters with one-way mapping. See here: **The lowdown:** The decoder strips this formatting so the full message can be read in plain text. You can upload your own screenshots, play with dictionaries, adjust region detection, or enter pseudo-Braille by hand. ### How to Use: 1.
