Engineered for velocity, safety, and control.
Discover how Zentara combines automated AI synthesis with transparent review workflows, responsive sandbox previews, and full developer-grade tools.
Plan / Build / Ask Workflow Engine
Deterministic Agent Collaboration
Switch seamlessly between non-destructive inspection (Plan), automated multi-file code synthesis (Build), and natural technical advisory (Ask). You retain full authority over when and where code is written.
Key Capabilities
- Plan Mode: Formulates structured proposed plans listing affected files, step-by-step milestones, and verification checks with zero file mutations.
- Build Mode: Synthesizes components, edits existing modules, updates styles, and orchestrates terminal test validation.
- Ask Mode: Provides contextual architecture guidance, explains complex codebases, and answers technical questions safely.
Safe Visual Design Mode
Point-and-Click Targeted Editing
Click any element directly in the live application preview to highlight it with electric cyan bounding overlays and ask Zentara for precise visual refinements without searching through lines of code.
Key Capabilities
- Visual overlay automatically captures DOM tag, text snippet, CSS selectors, and screen coordinates.
- Passes targeted element context straight into the Agent composer in Plan mode for safe proposed changes.
- Refine layout spacing, colors, font styles, and responsive alignment with immediate feedback.
Review Changes & Validation Engine
Authoritative Diff Verification
Inspect line-by-line git diffs with clear additions and deletions before promoting changes to your accepted project state. If any validation test fails, changes cannot be applied.
Key Capabilities
- Interactive Diff Viewer displaying multi-file staged modifications with syntax highlighting.
- Authoritative check resolution: deduplicates validation events and blocks reviews if tests fail.
- Zero-change safety gating: prevents false empty review states if no files were touched.
- Single-click Apply promotes files to workspace; single-click Reject restores pre-build snapshot immediately.
Fluid Multi-Device Preview
Proportional Responsive Scaling
Experience your application in true responsive viewports: Desktop (1440×900 fluid scaling), Tablet (768×1024), and Phone (390×844) with independent rotation and zero mobile frame distortion.
Key Capabilities
- Desktop preview occupies 85–95%+ of workspace without narrow mobile column collapse.
- Independent orientation controls for Tablet and Mobile with portrait and landscape modes.
- One-click 'Reset size' button to instantly recalibrate viewports upon resizing drawers.
Full Monaco Code Editor & Explorer
Direct Developer Control
A full-featured cloud IDE when you want to write or edit code manually. Includes full directory tree management, multi-tab buffer state, breadcrumb navigation, and syntax highlighting.
Key Capabilities
- Create, rename, move, and delete files or folders directly in the tree.
- Multi-tab editing with dirty buffer tracking, unsaved changes protection, and hotkey save.
- Integrated terminal with isolated command execution and diagnostic logging.
Project Isolation & Continuous Checkpoints
Private Sandboxes & Snapshots
Every build captures an immutable pre-build snapshot checkpoint. Code runs inside segregated container sandboxes with strictly scoped database credentials and secret scrubbing.
Key Capabilities
- Strict database record scoping and isolated micro-VM sandboxes.
- Instant checkpoint rollback to any previously accepted project state.
- Automatic redaction of tokens, database URLs, and API credentials from diffs and terminal logs.
