Xeref v4.x: Vision, Web Reading, and a Dreaming Agent

XerefAIVisionAgentsRelease Notes

The v4 series adds multimodal vision, live web reading, a nightly dream digest, and production-hardened MCP tooling — making Xeref's agents meaningfully more autonomous.

The v4 series has been about expanding what Xeref agents can perceive. Until now, agents worked entirely with text you gave them. With v4, they can read the web, analyze images, and even reflect on your day while you sleep.

v4.3 — Web Reading, Image Analysis, and Document Security

Read any URL: Paste a link into chat and XerefHermes will fetch and read the page text. Ask it to summarize an article, extract product specs, or compare two pages — available on all plans.

Image analysis: Attach an image or paste an image URL and Xeref will describe, analyze, or answer questions about it. Messages with images are automatically routed to a vision-capable model — Gemini 3.5 Flash on Pro, Claude Sonnet 4.6 on Ultra. Pro and Ultra only.

Document recall security: Uploaded files are now scanned for secrets (API keys, tokens, recovery codes, private keys) before being indexed or returned in chat. Sensitive content is masked as [REDACTED] and files with names like recovery-codes or .env are withheld from recall entirely.

v4.2 — XerefHermes Gets a Dreaming Function

Inspired by the Nous Hermes agentic OS, XerefHermes now dreams. A nightly dream:summarize handler reviews the last 24 hours of your tasks and activity, writes a short overnight digest with a suggested next focus, and saves it into long-term memory. Digests appear as searchable memory entries tagged dream-digest. A dedicated cron runs daily at 08:00 UTC and dispatches a digest for every active user.

v4.1 — Polish and MCP Compliance

  • Model picker descriptions: Each model now shows a short description in the chat input, agent panel, and Xeref Code. Your last-used model and planning-mode preference are remembered across sessions.
  • Checkout error toasts: Misconfigured keys, network errors, and missing product IDs now surface as clear in-app toasts instead of silent failures.
  • MCP JSON-RPC 2.0 compliance: Every response echoes the request id, notifications return 202, unknown methods return -32601, and tool errors return isError: true. This fixes compatibility with Claude Desktop and strict MCP clients.

The v4 series represents a step change in what Xeref agents can do on your behalf — not just responding to prompts, but perceiving the world and working in the background.
