Question: I'm looking for a platform that enables me to build decentralized applications with customizable privacy levels.

If you want a platform for decentralized apps with adjustable privacy, Oasis is a good option. It's got a confidential version of the Ethereum Virtual Machine (EVM) called Oasis Sapphire that offers a range of privacy options from totally private to totally public. That means developers can write private dApps with high performance and low gas fees. The platform also comes with tools like Solidity, the Oasis Playground and Academy for learning and development, so it's a good foundation for a variety of Web3 and AI projects.

Another interesting project is Ocean, which is designed to let people monetize AI models and data while protecting privacy through tokenized data and AI services. It uses Data NFTs with access controls and encryption, as well as Datatokens for permissioned access. Ocean enables decentralized data marketplaces and lets you build token-gated AI dApps and APIs, so it's a good option for data-centric projects.

Dynamic also offers a full-stack platform with tools for easy login, wallet creation and user management. It supports multiple chains, including EVM and Solana, and offers non-custodial access and passwordless login. With its built-in on/off ramps for converting fiat money into cryptocurrency and multi-chain support, Dynamic is good for a broad range of use cases, from NFT marketplaces to DeFi projects.

If you prefer a no-code approach, Toolblox could be a good option. The platform lets you create smart contracts and DApps with no programming, using a graphical interface and tools like a Contract Maker and DApp Maker. It's good for a variety of use cases, including supply chain management and gaming, and is good for quickly creating MVPs and prototypes.
