About

AstralDeep

Features
Read full description

AstralDeep gives you a team of specialist AI agents that work on your behalf — they research live sources, read your files, and keep working on your AstralDeep server after you close the app. And you can hold them to account: every tool is permission-gated, every action lands in a tamper-evident audit log, and nothing the platform builds for itself runs without your approval. AGENTS THAT ACT FOR YOU • Specialists collaborate on each request — live web research with citation-backed briefs (it never fabricates a source), summarization, weather, ML forecasting and classification, connectors, a general assistant — running multiple tools in parallel. • Hand them files in chat and they read them directly. • They remember what matters across conversations and personalize to you over time. IT KEEPS WORKING WHEN YOU DON'T • Schedule work and close the app — jobs run on your server; results are waiting in your workspace when you return. • Upload a file format it can't read yet and the platform drafts its own parser agent, self-tests it against your actual file, and submits it for administrator approval — once approved, it goes live and finishes your original request. • Ask for something no agent covers, and AstralDeep can generate a brand-new agent — security-gated, self-tested, and never run for real without explicit human approval. SECURITY YOU CAN VERIFY Delegation only works if you stay in control — and self-extension is only safe on a platform built to be inspected: • Per-tool permissions: grant and revoke access tool by tool, for every agent. Deny is the default — agents cannot touch what you haven't granted. • Tamper-evident audit: every tool call lands in a cryptographically hash-chained log you can check for tampering — see exactly what your agents did, and when. • End-to-end-encrypted credentials: service credentials you store can be decrypted only by the specific agent that needs them — the server itself never holds them in plaintext. • Attenuated authority: agents act with cryptographically scoped tokens carrying only the authority you delegated — narrower at every hop, never wider. • Sensitive-data guardrails screen text before it reaches outside services, agent network egress is gated, and every safety feature fails closed. LIVE ANSWERS, NOT WALLS OF TEXT Answers arrive as live components — dashboards, charts, tables, timelines — on a per-conversation canvas. Follow-ups update them in place, an adaptive designer arranges multi-part answers, and History steps back through earlier states. ON APPLE WATCH Sign in with a QR code (no typing), ask by voice, hear answers spoken aloud — plus glanceable cards and recent conversations. AstralDeep requires an account on an AstralDeep server; the app signs in through your organization's single sign-on.
