Estratum: Second Brain

SAVE WITHOUT ORGANIZING. FIND BY ASKING. An idea, an appointment, something to do. Write it however it comes and get on with your day. Estratum organizes your notes, tasks and appointments with AI and helps you find them in your own words. No folders to prepare. No need to remember where you put everything. YOUR MEMORY, WITH ON-DEVICE AI Organize, search and get answers on your device. After the model download, local mode works offline without sending your notes to an AI server. No Estratum account, tokens or per-query fees for local AI. SAVE NOW. ASK LATER. Write or dictate a note. Later, ask “What did we decide about Atlas?” or “What do I have tomorrow?”. Search by meaning helps you find it even with different words. Open the related notes to check the context behind the answer. FROM PAPER TO SEARCHABLE NOTES Photograph a document, review the recognized text and confirm. A printed appointment, receipt or set of instructions becomes something you can find by asking, rather than a forgotten photo. YOUR DAY, IN VIEW See appointments, tasks and deadlines in a timeline and calendar. Write repeating dates naturally, including yearly birthdays. Basic reminders keep track of what you saved; with Pro, smart reminders choose a useful lead time for the type of information. SEE HOW IDEAS CONNECT With Pro, explore your notes in the Knowledge Map. Tap a topic to highlight others that share notes and open their content. The Diary gives you another way to revisit what you have saved. SIRI AND APPLE WATCH, TOO Capture with Siri or Shortcuts without finding the app first. With Estratum Pro, dictate notes from Apple Watch and check your full upcoming agenda on your wrist. Watch captures reach your phone for organization there. Siri and dictation depend on Apple. BRING THE NOTES YOU ALREADY HAVE Import Markdown (.md) files, including from a folder of notes, with dates and tags. Choose which ones to process with Estratum AI. IPHONE, IPAD AND IPHONE DUO Light or dark mode. On iPad and an open iPhone Duo, write while consulting your information. Notes shows list and detail together; Calendar pairs the month with your agenda. Fold or switch displays and the layout adapts while keeping your draft. SYNC ONLY IF YOU NEED IT Optional, free iCloud sync brings your notes between iPhone and iPad. Records are encrypted on your device before leaving; the key syncs through your iCloud Keychain. Turn sync off or delete its cloud copy without deleting local notes. Document photos and AI models are not synced. FREE TO START. PRO WITHOUT A SUBSCRIPTION. Free includes unlimited saves, 7 questions per week, basic reminders and the same AI as Pro. Pro adds unlimited questions, Knowledge Map, Diary, Apple Watch, smart reminders, Apple Calendar integration and automatic Home/Work switching with the relevant permissions. Try Pro free for 14 days. Nothing is charged when it ends. The full unlock is a separate one-time purchase, not an Estratum subscription. YOUR INFORMATION. YOUR CHOICES. No ads or selling your data. Apple Private Cloud Compute and external providers are optional, consented cloud choices, not local processing. External providers need your own API key and may charge their own fees. Qwen requires a download and at least 6 GB RAM. Apple's on-device model depends on system availability. Without a local engine, you can configure an external provider. Estratum does not diagnose or treat health conditions. Available in English and Spanish. Write it down. Estratum takes care of the order.
