Single Grain
Single Grain keeps publishing AI-for-marketing how-tos, not product changes
A side-by-side editorial comparison of MySignature and Metricool — release velocity, themes, recent moves, and the top alternatives to consider.
MySignature turned its digital business card into a lead-capture surface, then instrumented it.
MySignature started as an email signature designer and has spent the last year building out a second product around digital business cards. August was the month that surface stopped being a way to hand over contact details and became a way to collect them: a Collect Contacts form block, a Contacts list behind it, and analytics on views, clicks, QR scans and traffic sources. The signature editor keeps advancing separately, with reply and forward variants the newest addition.
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.

The direction is from presentation to acquisition. Design tooling — drag mode, AI layout suggestions, banner campaigns — made signatures look better; the card work makes them measurable and makes them capture. That is a different business: a signature is a design asset, a card that collects and reports on leads is a small marketing channel, and the Contacts list is the first place MySignature holds customer data of its own.
Expect the Contacts list to grow the obvious next pieces — export, tagging, and a route into the CRMs and marketing tools its Teams customers already run.
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.
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.
