What it does
Traditional text steganography relies on invisible characters or formatting tricks that raise immediate flags. Stegveil.dev flips the script by hiding sensitive data inside natural, human-readable text. Using a novel preposition-based encoding algorithm, Stegveil embeds payloads directly into the grammar of the prose—leaving zero formatting tells or metadata trails.

Steganographically encode messages with LLMs and Arithmetic Coding2025 · github.com · ▲24Good morning HN! For a while now I have been toying with this idea and now finally have a working prototype. This project allows you to encode secret messages into ordinary looking text by using arithmetic coding with a probability model derived from an LLM. By encrypting the message and then decompressing the encrypted message using the arithmetic coder, you get output which looks just like randomly sampled output from the LLM. Except, it actually encodes your secret messages in the specific choices of tokens. By using authenticated encryption, only a user who knows the key can know that a…

Stun LLMs with thousands of invisible Unicode charactersNov 2025 · gibberifier.com · ▲206I made a free tool that stuns LLMs with invisible Unicode characters. *Use cases:* Anti-plagiarism, text obfuscation against LLM scrapers, or just for fun! Even just one word's worth of “gibberified” text is enough to block most LLMs from responding coherently.

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
