Enclave product preview2026 – now

Enclave

An offline-first, zero-knowledge knowledge base for Windows, Linux, macOS, and Android. Notes are encrypted with SQLCipher at rest and sync device-to-device over authenticated, AEAD-encrypted WebSocket channels — no cloud, no servers. An opt-in RAG assistant answers questions across your vault with in-database vector search and fully offline embeddings.

  • Zero-knowledge: a 12-word BIP39 seed phrase never leaves the device; Argon2id derives the key
  • Encrypted device-to-device sync over local Wi-Fi with a mutual-auth handshake — no servers
  • An offline RAG assistant answers across your vault without a byte leaving the machine

Nexus product preview2026 – now

Nexus

A self-hosted AI RAG workspace. Upload PDF, TXT, Markdown, CSV, and JSON documents into isolated workspaces; a BullMQ worker queue chunks and embeds them asynchronously, then chat with your documents over a streaming WebSocket — grounded answers with cited sources from hybrid pgvector + full-text search.

  • Uploads never block chat — BullMQ workers index documents in the background
  • Hybrid pgvector + PostgreSQL full-text retrieval, streamed token-by-token over WebSockets
  • Grounded answers with inline citations and a strict refuse-to-guess system prompt

Tempo product preview2026 – now

Tempo

Author a volleyball play on an accurate 3D court and walk into the gym with a shareable video instead of hand-drawn arrows. Tempo is a browser-based play designer and teaching tool: interactive quick-play authoring, a full 3D editor with keyframe timelines, coaching annotations, a live match scorecard, and client-side MP4 export via WebCodecs — plus a presentation PWA for the sideline and the official FIVB 2025–2028 rulebook bundled in.

  • From idea to shareable video in under a minute — no installs, no editing software
  • Frame-perfect WebCodecs renders with an ffmpeg.wasm fallback and GIF/slow-mo presets
  • Coach-grade scorecard: rallies, rotations, substitutions, sideout %, timers and match reports

Sentinel product preview2026 – now

Sentinel

A dependency-free Python CLI that watches GitHub repositories, websites, APIs, and PyPI/npm packages — and explains exactly what changed, not just that it changed. Durable SQLite history, watch mode, uptime statistics, and a safety-first updater that verifies checksums and audits every update.

  • Explains what changed, not just that it changed — releases, JSON fields, HTTP status, commits
  • Zero dependencies: Python 3.11+, pip install and go
  • Durable SQLite history with uptime statistics, watch mode and machine-readable output

Ratio product preview2026 – now

Ratio

A free, open-source money manager for Android that continues the Ivy Wallet codebase after upstream went unmaintained. 100% Kotlin and Jetpack Compose: accounts, budgets and categories, CSV import, debt and lending tracking, planned payments, and offline-first Room storage. Releases are built from source by GitHub Actions and signed as FOSS APKs — no store, no ads, no telemetry.

  • 100% Kotlin + Jetpack Compose with Material 3 and offline-first Room storage
  • Signed APKs built straight from source in GitHub Actions — no Google Play required
  • GPL-3.0, no ads and no trackers: your money data stays on your phone

JournalEdge product preview2026 – now

JournalEdge

A trading journal you will actually keep up to date. Paste rows straight from TradingView or MT4, drop a chart screenshot and let in-browser OCR read entry, stop-loss and take-profit while detecting long vs short by colour, or import full broker history from MT4/MT5, cTrader and more. Then review your edge with outcome badges, filters and Recharts analytics.

  • Three ways in: copy-paste, screenshot OCR, or a full broker history file
  • Auto-detects platform and columns, then previews every row before anything is saved
  • Profit / loss / breakeven / open outcomes derived automatically and filterable

CryptLearn product preview2025 – 2026

CryptLearn

An AI-assisted cryptography e-learning platform. Production-grade REST API with JWT access/refresh rotation in HttpOnly cookies, hashed refresh-token storage, and three-tier RBAC. The React frontend ships live Caesar, Base64, SHA, and RSA (WebCrypto) tools plus points, streaks, and badge analytics.

  • JWT access/refresh rotation in HttpOnly cookies with hashed refresh-token storage
  • Three-tier RBAC enforced across every API boundary
  • Live Caesar, Base64, SHA and RSA (WebCrypto) playgrounds
