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.

What is mlr3?

mlr3 is hardening the seams where its abstractions meet real learners

Releases arrive every few weeks and read as a systematic audit of the Learner interface. Recent versions added a native_model binding and a predict_raw flag so users can reach the underlying package's model and raw prediction, gave encapsulated learners a wall-clock deadline alongside the existing timeout, and removed the deprecated Task$divide(). A run of fixes addresses correctness at the boundary - factor level ordering that inverted binary probabilities, fallback learners losing state, misaligned probability columns.

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.

mlr3 is hardening the seams where its abstractions meet real learners

◆ Current state

Releases arrive every few weeks and read as a systematic audit of the Learner interface. Recent versions added a native_model binding and a predict_raw flag so users can reach the underlying package's model and raw prediction, gave encapsulated learners a wall-clock deadline alongside the existing timeout, and removed the deprecated Task$divide(). A run of fixes addresses correctness at the boundary - factor level ordering that inverted binary probabilities, fallback learners losing state, misaligned probability columns.

◆ Where it's heading

The framework is maturing from wrapping models to being accountable for what happens when wrapping goes wrong. Structured Mlr3Error and Mlr3Warning classes, conditions stored on the learner log, and messages replaced by conditions all point at making failures programmatically inspectable rather than printed. In parallel, escape hatches to the upstream model are being formalised instead of left to users digging into internals.

◆ Prediction

Expect the remaining deprecated surface to follow Task$divide() out, and further work on encapsulation and fallback behaviour, which is where most recent fixes have clustered. The raw and native_model accessors suggest more of the upstream model will be surfaced deliberately.
