Tategoto lets you hide what you really want to say inside a message that looks completely ordinary. WHAT IT DOES You type your true message. AI writes a natural-sounding note, placing one letter of your message at the start of each line. Read down the left edge and the hidden words appear — the wordplay known as an acrostic in English, 縦読み in Japan, 삼행시 in Korea, and 藏頭詩 in China. NO PROOFREADING NEEDED Tategoto checks every line against your hidden message automatically, and quietly rewrites any line that drifts. You never have to count letters yourself. NO SUBSCRIPTION By default it runs on Apple Intelligence, the AI built into your iPhone. Nothing you type is sent anywhere, and there is no monthly fee. If you already have an API key for Claude, ChatGPT, or Gemini, you can switch to it in Settings for noticeably more natural writing — Gemini has a free tier that is generous enough for everyday use. FITS WHERE YOU'RE SENDING IT Choose whether you're pasting into a messaging app or an email, and line lengths adjust so the text won't wrap on the recipient's screen and break the hidden reading. SMALL THINGS THAT MATTER • Name the recipient, or ask for specific words to be woven in • Rewrite any single line, as many times as you like, free • Edit the whole text freely before you copy it • Common messages appear instantly, without using AI at all FIVE LANGUAGES English, Japanese, Korean, Simplified Chinese, and Traditional Chinese. Tategoto detects the language of your hidden message and writes in the form that fits that culture. PRICING Free for your first five messages. After that, a single one-time purchase unlocks unlimited use. No subscription, ever. Some things are easier to say sideways.

Verdict
The clearest difference is in-app purchases: KollusPlayer at none against Tategoto's 1. Tategoto's advantage is update cadence (every 11 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
