Zatanna turns all software into agent-first APIs by reverse engineering requests and managing anti-bot infrastructure. The company converts browser automation workflows into reliable APIs for AI agents, eliminating the need for slow, brittle computer-use interactions with legacy software systems. Zatanna is part of Y Combinator's Winter 2026 batch.

- What problem does Zatanna solve?
- It replaces slow, brittle browser automation and computer-use interactions with reliable APIs, so AI agents can interact with software that does not expose official programmatic access.
- How does Zatanna create these APIs?
- It reverse-engineers the network requests behind an application and manages anti-bot infrastructure, exposing those interactions as stable, agent-first APIs.
- Why not just use browser automation?
- Browser and computer-use automation tends to be slow and breaks easily when interfaces change. Zatanna aims to provide a more deterministic, lower-latency API layer instead.
- Who is Zatanna built for?
- Developers and teams building AI agents that need to reliably operate across third-party or legacy software systems that lack usable APIs.
