Single Grain keeps publishing AI-for-marketing how-tos, not product changes
A side-by-side editorial comparison of Postiz and Metricool — release velocity, themes, recent moves, and the top alternatives to consider.
Postiz v2.25 adds preview comments and relays Cloud MCP to self-hosted instances.
v2.25.0 on 2 October adds inline comments on post previews, with replies, resolving and anonymous commenting, plus a self-hosted connector that lets Postiz Cloud relay MCP tool calls to a user's own instance. A provider sweep turns dozens of Unknown Error failures into readable, correctly retried errors, and stalled media reads can no longer hang a publish. It follows August's streamed uploads and duplicate-post protection.
Metricool's feed is all how-to guides, now including one for its ChatGPT connection.
Metricool published five more articles on November 12 and 13: lead generation, posting frequency, community building, holiday campaigns and a guide to connecting Instagram to ChatGPT through Metricool. The ChatGPT guide is the only one tied to a product capability, and it documents an existing connection rather than announcing a release. Earlier entries were careers explainers and walkthroughs of the approval and inbox tools.

Reliability remains the steady line, but features have returned after a stretch dominated by security releases. Comments open the preview to people without an account, which suggests client review as a use case. The MCP work has moved from fixing OAuth to connecting self-hosters with the Cloud Claude connector and returning preview links an agent can share.
Expect more MCP tool additions, since the agent path is getting steady attention, and continued provider error mapping. The past security-release pattern keeps another advisory patch plausible.

The ChatGPT guide is the only one tied to a product capability, and it documents an existing connection rather than announcing a release. Earlier entries were careers explainers and walkthroughs of the approval and inbox tools.
The feed is a content-marketing channel aimed at small businesses and agencies, not a changelog. The ChatGPT guide suggests Metricool wants its analytics data used inside AI assistants for post planning, but the entries never say when or how that connection shipped.
More evergreen guides are near certain; whether Metricool extends the AI-assistant connection beyond Instagram and ChatGPT is unclear from these entries.
