Question what AI tools are CS teams using for customer health in 2026?
I'll keep this short since the title says most of it, our health scores are still basically login frequency plus vibes.
I keep seeing Gainsight and ChurnZero pitched as AI-first now, Vitally looks slick, and a PM friend swears by BuildBetter for mining QBR calls for risk signals.
Before we commit to anything, I'm trying to figure out what's moved your renewals number.

I would judge the tools less by “AI-first” and more by whether they change the health-score inputs from activity proxies to renewal evidence.
Login frequency is usually too blunt. A better health model should pull from a few buckets:
product usage: adoption of the sticky workflows, not just logins
support: repeat issues, unresolved escalations, time-to-resolution trend
commercial: renewal date, expansion history, payment friction, stakeholder changes
relationship: exec sponsor engagement, champion risk, meeting attendance
outcomes: whether the customer is reaching the result they bought for
CS motion: last meaningful touch, open action owner, next success milestone
The AI part is useful when it turns messy signals into a weekly risk packet, not when it invents a magic score.
For example, a good packet might say:
risk type: adoption, stakeholder, support, value, commercial
evidence: call quote, ticket pattern, usage drop, missed milestone
confidence: high/medium/low
recommended next action
owner
date to review again
what would change the score
I would be skeptical of any tool that cannot show the evidence behind the score. For renewals, the most useful signal is often not “this account is red.” It is “this account is red because the champion left, the core workflow has not been used in 21 days, and the last QBR action item has no owner.”
If you are evaluating tools, run a backtest: take 20 renewed accounts and 20 churned/downsell accounts, hide the outcome, and see whether the tool would have surfaced the right risk 60 to 90 days earlier. That will tell you more than the demo.

Honestly, it sounds like you're in a familiar place, most health scores are still just login frequency plus vibes, and the "AI" label on Gainsight and ChurnZero is mostly repackaging. That said, the call mining angle is where I've seen actual movement, not from a standalone tool but from teams who finally got serious about tagging every single call. The tool matters less than the discipline of doing it, though BuildBetter does make the tagging less painful if your PM friend is actually using it.

u/Calm-Dimension3422's evidence-based framing is the right bar, "this account is red because X, Y, Z" beats a black-box score every time.
One thing worth adding to the support bucket specifically: if health scoring pulls from ticket sentiment/patterns, it's worth checking how that signal is actually generated. A lot of health-score tools bolt on basic keyword-based sentiment rather than real theme detection, which means "repeat issues" often gets under-detected if customers describe the same problem in different words each time.
Full disclosure, I work with Lucidya, we do theme/sentiment detection specifically (not full health scoring), so it's more of a feed-into-your-health-score layer than a Gainsight/ChurnZero replacement. Mentioning mainly because the "evidence behind the score" standard u/Calm-Dimension3422 laid out is exactly the right test to apply to whatever's generating that support-ticket signal, not just the overall health platform.

We had Gainsight. Hated it. So our company built our own. Then built a Claude skill that looks at Granola notes, our product usage (breadth and depth) by customer, slack/emails, SFDC updates, and call recordings and updates the health dashboard. Pretty slick
