Record meetings, lectures, and calls โ€” let AI transcribe, identify speakers, and summarize them in seconds. Generate stunning images from a simple text prompt, powered by Google Gemini. One app. Every AI tool. Meet COET. COET: One App. Every AI Tool. Two world-class AI tools in a single app โ€” with more on the way. COET is the all-in-one super-app that brings every AI tool you actually use into a single, beautifully designed experience, for one price. Record a meeting, summarize it, generate the cover image for your recap, and send it anywhere. No app-switching. No context loss. No separate subscriptions. WHY COET? Most AI apps do one thing. You end up paying $40+/month across a handful of separate subscriptions โ€” none of which talk to each other. COET ends the chaos with a single, unified app where every tool is AI-native by design โ€” starting at just $2.99/week. KEY FEATURES: NOTE TAKER Capture meetings, lectures, phone calls, and ideas with one tap. COET records hours of audio, transcribes it with AssemblyAI's world-class speech-to-text, identifies each speaker, and generates clean AI summaries using Meta Llama 4 running on Groq. Search, rewrite, and tag your notes. Export to Email, Notion, OneNote, Evernote, or anywhere you work. Replaces Otter and Rev. MEDIA AI Generate and edit images just by describing what you want โ€” portraits, illustrations, product shots, scenes. Powered by Google Gemini 2.5 Flash Image (also known as "Nano Banana"). No Midjourney or DALL-E subscription required. PRIVACY AND TRANSPARENCY Your data is yours. Stored on Google Firebase with encryption in transit and at rest. Transcripts are processed by AssemblyAI (audio deleted immediately after transcription). Summaries and rewrites run on Groq (not retained). Images are generated on Replicate (inputs and outputs auto-deleted within one hour). Subscriptions are managed through RevenueCat. None of our AI partners use your content to train their models โ€” this is contractually guaranteed. You control AI permissions feature-by-feature and can withdraw consent at any time. MORE APPS. ONE SUBSCRIPTION. EVERY PLATFORM. COET is just getting started. New AI mini-apps ship continuously, and your subscription unlocks every one as it lands SUBSCRIPTION INFORMATION To provide a distraction-free, ad-free experience with unlimited access to every AI tool, COET offers a Pro subscription in two plans. Pricing and Terms: COET Pro Weekly: 2.99 USD per week. No free trial. COET Pro Yearly: 19.99 USD per year, with a 3-day free trial. That works out to less than 0.39 USD per week โ€” our best value. Pricing may vary in other countries and actual charges may be converted to your local currency depending on the country of residence. Payment will be charged to your iTunes Account at confirmation of purchase. Auto-Renewal Logic: Your subscription will automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period at the cost of the selected plan (2.99 USD weekly or 19.99 USD yearly). If you start the yearly plan with a free trial, you can cancel anytime during the 3-day trial period at no charge โ€” otherwise the yearly subscription will begin automatically at the end of the trial. How to Manage/Cancel: You can manage your subscription and turn off auto-renewal by going to your iPhone Account Settings after purchase. Step-by-Step for Cancellation: Open the Settings app. Tap your name. Tap Subscriptions. Tap COET. Tap Cancel Subscription. Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable.
