A side-by-side editorial comparison of Dovetail and Grafana Loki — release velocity, themes, recent moves, and the top alternatives to consider.
Dovetail opens its docs to Claude and ChatGPT as co-authors.
Channels 2.0 reached general availability on October 21, with activity logs, snapshot summaries and a Sources beta for feedback integrations. In early November Dovetail let Claude and ChatGPT read and edit Dovetail docs from the conversation, offered access to teammates who are @mentioned in a doc they can't open, and taught its own Chat to answer how-to questions from the help docs.
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

After the Channels work, the focus has moved to docs and the assistant layer: external AI assistants now write into Dovetail, and the in-app Chat covers product help as well as research questions. Dovetail is positioning its docs as a place both people and outside assistants work in.
Expect more actions exposed to external assistants beyond docs, such as channels or evidence, and further Chat coverage of in-product tasks.

Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
