Movement

This is the first edition on this tier, so no move can be computed for Slack yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated Slack across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“However, if you are hiring younger talent or have a "customer-experience first" sales culture, stick with Slack.” Qwen 3.7 Flash · Internal communications · paraphrase prompt · first choice

“Slack is the better choice if your company runs on Google Workspace or is more tech-forward” DeepSeek V4 Flash · Internal communications · paraphrase prompt · first choice

“For most mid-sized B2B companies, Slack or Microsoft Teams are the safest choices” Claude Haiku 4.5 · Internal communications · paraphrase prompt · first choice

“I'd recommend Slack or Microsoft Teams for most mid-sized B2B companies.” GLM 4.7 FlashX · Internal communications · paraphrase prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“General tools to avoid for pure frontline: Slack/Teams ... low adoption among deskless workers” Grok 4.1 Fast · Frontline employee apps · direct prompt · hard negative

“Slack / Teams are strong for messaging and collaboration but limited in employee engagement features, governance, and frontline‑specific workflows.” GLM 4.7 FlashX · Frontline employee apps · direct prompt · soft negative

“Office tools like Slack or Microsoft Teams often fail on the frontline because they assume every worker has a laptop, corporate email” Gemini 3.5 Flash · Frontline employee apps · scale prompt · soft negative

“Slack can be poor if you need structured engagement or HR insights, since it is mainly a messaging tool.[2]” Perplexity Sonar · Employee engagement surv · negative prompt · soft negative

A head-to-head page exists where both products are in a category's top three. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named Slack. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 59 of the 99 answers that named Slack and are not a share of its labels.

Names read as Slack

What the judge wrote, as written, with how often. The vendor table decides that these count as Slack; a claim can dispute any of them.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Slack's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Slack, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at slack.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
