What is Docling?

Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.

Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.

What is Dosu?

Dosu moved from maintaining your repo to measuring what your coding agents actually did.

Dosu started as an AI teammate for repository upkeep — documentation freshness scoring, stale-issue triage, templated release notes — and spent the spring making that configurable through Libraries and Agents. It dropped its waitlist in July and added usage analytics so teams could see its impact. Decant is a departure: a local tool that reads Claude Code and Codex session logs and reports what those agents did and what they cost.

Docling vs Dosu: editorial side-by-side

Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.

◆ Current state

Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.

◆ Where it's heading

The engine layer is where the interesting movement is. Docling is shifting from one opinionated pipeline to a set of interchangeable layout, table and OCR backends the caller picks per run, which turns the library into a harness for models rather than a fixed parser. A second thread: the project shipped agent skills for itself in v2.118.0 and a separate docling-client package in v2.120.0, both pointing at being consumed programmatically rather than only imported. The structural-inference work — heading levels from font weight, now from DOCX outline levels — shows the parser learning to read documents that never declared their own structure.

◆ Prediction

Expect the engine-selection surface to keep widening, with OCR joining layout and table structure as a CLI-selectable backend. The steady stream of format-specific crash fixes suggests coverage is outrunning hardening, so more of these short corrective releases are likely between feature drops.

6.3

Dosu moved from maintaining your repo to measuring what your coding agents actually did.

◆ Current state

Dosu started as an AI teammate for repository upkeep — documentation freshness scoring, stale-issue triage, templated release notes — and spent the spring making that configurable through Libraries and Agents. It dropped its waitlist in July and added usage analytics so teams could see its impact. Decant is a departure: a local tool that reads Claude Code and Codex session logs and reports what those agents did and what they cost.

◆ Where it's heading

The through-line is that Dosu keeps productizing the parts of agent work that are hard to see — first whether docs were stale, then whether Dosu itself was earning its place, now whether anyone's coding agents are. Building Decant to run locally rather than as a hosted service sidesteps the objection that session logs are sensitive, which suggests it is aimed at teams that would not upload them. The feed is excerpt-only, so the depth of the tool is not visible from the changelog alone.

◆ Prediction

The obvious next step is connecting Decant's per-session cost data back to Dosu's own analytics, so a team can compare what its coding agents spend against the maintenance work Dosu absorbs — though the entries do not yet confirm that direction.
