Free

Local web UI for the Pi coding agent — browse sessions, switch worktrees, manage models, and chat beside your project files in a browser.

Session Browser: Reads local Pi session files and organizes prior conversations by project for quick resume.
Fork and Continue: Continue from any earlier message or fork a session into a separate route to try alternatives safely.
Git Worktree Switcher: Switch between Git worktrees from the sidebar to work on multiple branches in parallel.
File Preview: Side-by-side chat and project file browser that previews source, docs, images, audio, and PDFs.
Model and Skill Manager: Configure models, API keys, run model tests, and toggle skills from the web UI instead of CLI flags.
Local-Only Runtime: Runs on http://127.0.0.1 by default so session data and code never leave the developer's machine.

Resume Prior Work: Reopen a conversation from last week by project instead of scrolling terminal history.
Safe Experimentation: Fork a session to try a risky refactor without losing the original conversation state.
Parallel Branch Work: Switch Git worktrees mid-session to jump between feature branches in one workspace.
Model Comparison: Rerun the same task against different configured models to compare output quality.
In-Browser Code Review: Preview generated diffs and project files beside the chat without leaving the browser.

Freemium

A zero-knowledge vault that lets AI agents request sensitive data on demand, unlocked by Face ID or passkey and redacted after each task.

Zero-knowledge Vault: Sensitive data is encrypted client-side so Rivault never has access to the underlying values by default.
Per-request Auth: Every agent access triggers a fresh authorization request that you approve with Face ID or a passkey.
Deterministic Redaction: Data is scoped to a single task and redacted from the agent's context after completion.
Agent-agnostic Integration: Works with chat-based AI agents and Computer Use Agents that automate browser or desktop flows.
Ownership of PII: Store SSN, payment info, phone numbers, and emails once and reuse without leaving copies in session logs or memory.
Biometric Unlock: Face ID or passkey approval keeps the human in the loop for every sensitive field release.

Agent-driven Bookings: Approve passport and card details on-demand when an agent books flights or hotels.
Automated Form Fill: Let CUAs complete government or insurance forms without leaving PII in browser logs.
Customer Support Delegation: Grant scoped access to account numbers when an agent handles a service call for you.
Recurring Task Automation: Reuse stored credentials across many agent workflows without pasting them each time.
Enterprise Agent Deployments: Add a consent + audit layer for teams deploying agents that touch sensitive employee or customer data.
