Project Status

Spillway is private pre-alpha software. The current development milestone is Primary Client Readiness: making the macOS and iPhone applications work as one coherent everyday email client before higher-level planning features depend on incomplete platform behavior.

What is working now

  • Gmail-based mail reading and organization on macOS and iPhone.
  • Hierarchical, multi-category filing with human review and correction.
  • SQLite-backed local persistence, backup, restore, recovery snapshots, and bounded large-mailbox reads.
  • Local AI through Ollama and optional OpenAI, Anthropic, and Gemini adapters.
  • Work Ledger, dates, opportunities, drafts, attachments, and supported Gmail actions in varying stages of validation.
  • iCloud-backed cross-device synchronization for the category taxonomy and human category assignments, confirmations, and removals.

The sync implementation uses durable operation journals, deterministic reducers, account-scoped portable message identity, and a provider-neutral transport boundary. iCloud is the current reference transport for Apple devices. AI predictions remain device-local rather than becoming authoritative synchronized human decisions.

Current focus

The near-term work is completing the iPhone experience needed for ordinary daily use:

  • complete on-device AI and sync configuration;
  • honest sync, pending, offline, and recovery status;
  • configurable message-list swipe actions;
  • Compose, Reply, Reply All, and Forward;
  • correct HTML reading and HTML-preserving reply and forwarding;
  • reliable drafts, send status, and recoverable errors;
  • Calendar invitation handling that does not depend on Apple Mail being opened.

Important limits

Cross-device synchronization currently covers the category taxonomy and human category filing state. It does not yet imply synchronized Work Ledger items, requests, dates, opportunities, drafts, templates, every message status, or derived AI insights.

The current implementation is intended for bounded personal-use testing. More demanding institutional and mixed-trust deployments require additional security architecture, including selective trust zones, revocation, encryption-domain design, and policy-aware derived-data handling.

Historical Gmail acquisition has an approved design and remains planned after the primary-client workflow is dependable.
