What is Comet?

Comet is annexing AI cost governance from the observability side.

Comet's feed mixes real Opik engineering with a steady layer of SEO explainers, and the last two weeks have been almost entirely the latter — model-selection guides and an observability tools roundup. The product substance sits slightly further back: Agent Diagnostics, which reads across traces instead of one at a time, plus Cost Intelligence and an MCP server optimization pass. Bodies arrive as RSS teasers, so direction is readable but scope is not.

What is Recall?

Handwriting and screenshots become searchable cards, and the extension reaches Safari

Recall's August release is the broadest in months. OCR turns photos, screenshots and handwritten notes into real cards; the browser extension now runs on Safari and Edge alongside Chrome and Firefox, with connection editing inside the extension; chat proposes questions drawn from the saved library; and content can be added ten URLs at a time or by drag and drop. This follows a July that moved search into the full library page with text and AI modes searching reader content, notes and quizzes rather than titles.

Comet is annexing AI cost governance from the observability side.

◆ Current state

Comet's feed mixes real Opik engineering with a steady layer of SEO explainers, and the last two weeks have been almost entirely the latter — model-selection guides and an observability tools roundup. The product substance sits slightly further back: Agent Diagnostics, which reads across traces instead of one at a time, plus Cost Intelligence and an MCP server optimization pass. Bodies arrive as RSS teasers, so direction is readable but scope is not.

◆ Where it's heading

Opik is widening from tracing into two adjacent jobs: telling teams which model to run where, and telling them what that choice costs. Cost Intelligence, the MCP token audit, and now a model-selection guide all point at spend governance as the commercial wedge, with evaluation-driven development as the methodology wrapped around it. The Oracle Open Agent Specification integration adds a portability argument on top — instrument once, keep the framework choice open.

◆ Prediction

Expect model selection to stop being advice and become a product surface — routing or recommendation driven by Opik's own trace and cost data, sitting next to Cost Intelligence.

Handwriting and screenshots become searchable cards, and the extension reaches Safari

◆ Current state

Recall's August release is the broadest in months. OCR turns photos, screenshots and handwritten notes into real cards; the browser extension now runs on Safari and Edge alongside Chrome and Firefox, with connection editing inside the extension; chat proposes questions drawn from the saved library; and content can be added ten URLs at a time or by drag and drop. This follows a July that moved search into the full library page with text and AI modes searching reader content, notes and quizzes rather than titles.

◆ Where it's heading

Two threads have been converging all summer. One widens what can enter the library — social posts, Apple News, text and Markdown files, and now anything a camera can photograph. The other makes what is already inside retrievable: full-content search, personas, cross-card chat, and now suggested questions. OCR closes the last major gap on the input side, since paper was the one source that could not get in.

◆ Prediction

The mobile search overhaul is explicitly promised and is the most likely next release. Suggested questions plus full-content search point toward retrieval quality inside chat becoming the next area of investment.
