You have read it four times. Every version you draft is either too much or too little, and it has been sitting there twenty minutes. SayThis is an AI keyboard that reads the message you are stuck on and writes the reply, in the tone you choose, in the app you are already in. HOW IT WORKS 1. Give it the conversation. Use the SayThis keyboard without leaving the thread, take a screenshot, or copy the message. 2. Choose how you want to sound. Auto picks the voice, or choose from sixteen tones and three lengths. 3. Read it and send it. SayThis puts the draft in your message box. The send button is still yours. WHAT IT IS GOOD AT • The text you have reread four times • Saying no without sounding difficult • Answering your boss, your landlord, your group chat • Replying on dating apps without overthinking it • The ones you keep putting off until they are awkward • Marketplace haggling and money conversations • Replying in a language you read better than you write SIXTEEN TONES Natural, Friendly, Confident, Professional, Casual, Funny, Flirty, Empathetic, Firm, Apologetic, Persuasive, Calm, Supportive, Direct, Warm and Enthusiastic. Or leave it on Auto and let SayThis pick. THREE LENGTHS Short, Normal or Detailed. "Sorry, can't" and a proper explanation are different answers, and you pick which one you are sending. THE KEYBOARD SayThis installs as a keyboard, so it works inside Messages, WhatsApp, Instagram, Gmail and anywhere else you type. A keyboard genuinely cannot read your conversation, so SayThis does not pretend to. Take the screenshot everyone already knows how to take, and it reads the thread from that, usually on your phone. ANY LANGUAGE It answers in the language the other person wrote in, or one you pin. NOT QUITE RIGHT? CHANGE IT Too long, make it shorter. Not the voice you wanted, change the tone. Want a different angle entirely, ask for another. It rewrites until it is the one you would have written. WHAT IT NEVER DOES SayThis never sends anything itself. It writes the draft, puts it in your box, and stops there. Every message is yours to read, edit and send. PRIVACY Your conversations are not stored. Screenshots are read and then deleted. The reply is held for five minutes so a retried request is not charged twice, and nothing else is kept. You are asked before anything is sent for processing, and you can say no. The keyboard never reads while you type, and the reply panel does not appear in password fields. SAYTHIS PRO Your first five conversations are free. After that, a subscription unlocks unlimited replies, the keyboard and screenshot reading: • SayThis Pro Weekly • SayThis Pro Yearly, with a 3-day free trial • SayThis Pro Monthly, when offered in the app Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscription in your Apple Account settings after purchase. Any unused portion of a free trial is forfeited when you purchase a subscription. Terms of Use: https://getsaythis.com/terms Privacy Policy: https://getsaythis.com/privacy

Verdict
The clearest difference is ads: SayThis at none against Codebook's shown. Codebook's advantage is ratings volume (30 vs 1). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Codebook sells 10 in-app purchases, starting at $2.99 per 7 days and SayThis sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Codebook against 5.0 for SayThis. That said, the two scores are not equally well evidenced: Codebook has 30 ratings behind it against 1, so its average is the more settled of the two.
Codebook ships an update every 3 days, SayThis every 4 days. The most recent releases landed on November 3, 2026 and November 6, 2026 respectively.
