Vana vs Prezo

Vana is open data infrastructure for human-grounded AI, built around a personal server you control on your own device. Connect accounts like Spotify, Oura, and your calendar, see what you have created across platforms, and decide which apps or AI tools get access. The Vana App at app.vana.org is the consumer entry point, while docs and SDKs on GitHub support builders who want user-owned context without rebuilding memory from scratch.

Major AI assistants added proprietary memory in 2025 and 2026, but each keeps context on its own servers and it does not travel when you switch tools. Vana's 2026 App upgrade stores that context locally and exposes it through Portable Memory MCP, so Claude, ChatGPT, and other MCP clients can read from one source you own. That is the trade-off: you manage permissions yourself instead of accepting a platform's walled garden.

Builders use the Data Portability API to ship apps that request data directly from users rather than scraping third-party platforms. The Vana Foundation runs grants, cohorts, and a 1.5 million-person data network for contributors who want their information to create value. Enterprise teams route to OpenDataLabs for licensed training data, separate from the consumer app.

Prezo turns uploaded files into an AI workspace where you talk, search, and create presentations, documents, and websites. You drop files into an Orb, then ask questions or generate outputs like personal sites and general presentations from templates on the homepage. It fits creators and professionals who want one place to organize files and draft visual content.

Most AI slide tools only generate decks from a prompt. Prezo positions the Orb as a smart folder that holds your source files and powers search and creation on top of them. That file-first model trades a simple one-click slide generator for a workspace you build over time.

Prezo targets users who need lightweight sites, docs, and decks without switching between a file manager and separate design apps. The homepage offers sign-up login with starter templates for personal sites and presentations, and terms list the service as Q by Barrel Through Inc. in California.
