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 — 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).

Verdict
The clearest difference is in-app purchases: Plato Lock at none against DeeperAI's 3. DeeperAI's advantage is update cadence (weekly vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
