DeeperAI is an iPhone, iPad, and Mac app that helps you organize thoughts as a tree structure and explore them deeply with AI. Buy once, use on all platforms. [How It Works] Create a theme and break it down into sub-themes hierarchically. When you're stuck, AI suggests candidate sub-themes. Adding notes to your themes improves the quality of AI suggestions. [Antenna] Register topics you want to watch, and Claude periodically searches the web to summarize the latest information. The app auto-checks on launch and sleep-wake, and notifies you when new updates are found. [Chat] Open the chat while a theme is selected, and Claude responds with full awareness of that theme's context. You can also ask Claude how to use the app. Chat responses can be saved directly as sub-themes or attachments, letting you systematically build up knowledge within your tree. [More Features] - Tags and resource (assignee) management - Schedule and deadline management with Calendar integration - iCloud Drive sync โ€” share your data between iPhone, iPad, and Mac - Export and import data files (.dpai) [Pricing] The free plan allows up to 3 top-level themes and 3 levels of depth, with a lifetime AI allowance of 50,000 tokens. - **Premium** ($14.99/month): Unlimited themes and depth + 1M AI tokens/month included. No API key needed. - **Unlimited** ($39.99 one-time): Unlimited themes and depth. For users with their own Anthropic API key (pay-as-you-go, no token limit). Chat and Antenna features require a Premium subscription or your own Anthropic API key. End User License Agreement: https://ironasam43.github.io/ironasam43/legal/eula

You think things through with AI. The thinking never becomes a document. KakiDoc is built to close that gap. A GOOD CONVERSATION, AND NOTHING TO SHOW FOR IT You talked it through. It got clearer. But the conversation only scrolls away โ€” hard to read back, harder to hand to anyone. Copy it out, redo the headings, reorder the parts... and that is usually where it stops. WHEN IT'S READY, ONE BUTTON A new document opens as a chat-only screen. Throw in whatever you have, bullet fragments are fine. The AI fills the gaps with suggestions, and asks with options when it needs a decision. When the shape is right, press Turn into a document. You get a few ways it could be structured. Swipe through them and read exactly what each one would write. Pick one, press Create the document, and that is the moment it is created. AN AI THAT DOESN'T WRITE UNTIL YOU SAY SO If the list looks wrong, go back and keep talking. Nothing is written behind your back. Thinking and drafting are separate here, so you never get a finished piece handed to you while you are still working out what you mean. THEN REVISE, ONE SENTENCE AT A TIME Once the document exists, tap the sentence or block you want to change and ask: "shorten this", "make it more formal". Undo is one tap, and around 100 versions of history are kept. A PREVIEW WORTH READING Tables, code blocks, Mermaid diagrams, maths, callouts, images and video are all rendered as you write. WHAT YOU WRITE STAYS YOURS Nothing is locked inside a chat. Documents are stored in your own iCloud (CloudKit). The developer cannot access them. The format is plain Markdown, so other apps can open it. Export to Markdown, HTML, PDF or PNG, or send everything including images as a transfer pack (.mdpack). PRICING Creating, editing, previewing, iCloud sync and export are free, with no sign-in. AI features (chat, AI editing, web research) need an Apple Account sign-in and come with a free allowance to try. That allowance is one-time and does not reset monthly. A subscription is required to keep using AI. REQUIREMENTS iPhone and iPad. All AI processing runs in the cloud (Google Gemini).
