Best AI Tools for Customer Success Managers on Renewal Calls (2027)

The best AI tools for customer success managers on renewal calls cover two different jobs. Customer success platforms such as Gainsight, ChurnZero and Vitally track health, usage and renewal risk between calls. Call tools cover the conversation: Gong, Avoma and Fathom capture and analyze it, while Proshort's Aria privately puts sourced answers on the CSM's screen during the renewal call itself.

Disclosure: we build Proshort, one of the tools below. Competitor capabilities and prices were checked on each vendor's site in November 2026; Gong figures are attributed third-party estimates.

Key takeaways

• A renewal call needs five things: account context, open commitments, risk signals, accurate answers to pricing and contract questions, and follow-through after the call.

• Customer success platforms own the account picture between calls (health, usage, success plans, renewal forecasts). None of the three we checked describes help during the call.

• Of the tools checked, Proshort (Aria Live) and Avoma (real-time answer cards) describe putting answers on the CSM's screen while the customer is talking.

• Most CS teams need one tool from each side, so check how they connect before comparing prices.

What does a customer success manager need on a renewal call?

A renewal or QBR customer already knows your product and every promise made in the last year. CSMs lose credibility fastest by forgetting a commitment, missing a risk hinted at for weeks, or stalling on a pricing question.

1. Account context. Who is on the call, what changed since last time, usage trends, open support issues.

2. Open commitments. What your team promised (a feature, a fix, a training session) and whether it happened. Customers remember these.

3. Risk signals. A champion going quiet, a new stakeholder, a competitor mention, falling usage. See them before the call, not on it.

4. Live answers. Pricing tiers, contract terms, security questions, roadmap positions. A wrong answer costs more at renewal, because the customer remembers what they were told last year.

5. Follow-through. A recap in the customer's words, an owner for each action item, and CRM or CS-platform updates the same day.

No tool covers all five equally. The table shows which part each one takes on, per its own site.

Which AI tools help customer success managers on renewal calls?

Gong does not publish prices. Third-party estimates put its license at about $1,360 to $1,600 per user per year at list plus a platform fee of $5,000 to $50,000 a year (Avoma, October 2026; MarketBetter, August 2026). Our Gong pricing breakdown works out team-size totals.

How do the tools compare for renewal work?

Proshort (Aria): help during the renewal call

Aria joins the Zoom, Google Meet or Microsoft Teams call and puts the right answer, the proof point and the next question on the CSM's screen the moment the customer asks. Only the person using Aria sees it; the customer sees a normal meeting with the standard recording notice. Answers come from your own battlecards, docs and won calls, with the source shown, in under a second.

Around the call, Ask Aria answers questions such as "Brief me on all my upcoming calls today" with sources, and can send it as a scheduled morning email. Pattern and signal detection surfaces signs such as a champion going silent or a document asked for twice. Afterwards Aria drafts the recap with action items, owners and the next step; the CSM reviews and sends.

Best for: CS and account management teams whose renewal calls include pricing, contract, security or competitor questions that need an accurate answer on the spot.

Gainsight: the account picture and long-tail renewals

Gainsight describes a shared customer story that combines usage, health, goals, relationships, sentiment and commercial context. Its AI agents include a Risk Analyst that surfaces emerging risk and explains what changed, and an Expansion Analyst for growth signals. Atlas, its AI-native renewal service, uses autonomous agents for outreach and renewal motions across the long tail, backed by Gainsight renewal specialists.

Best for: large CS organizations that want health, success plans and renewal forecasting in one system, plus coverage for accounts no CSM reaches.

ChurnZero: an assistant inside the CS hub

ChurnZero's Kit answers questions about any account, for example a request for your 20 biggest renewals with usage down and no recent meeting, which can be saved as a live segment. Kit drafts pre-renewal emails that wait for your review. Named agents include Harbinger, which spots relationship risk early, and a Business Review Playbook that prepares QBR materials such as attendee context, talking points and a deck.

Best for: CS teams that run renewals from a CS platform and want AI prep and outreach inside it.

Vitally: assistant and meeting notes in one place

Vitally's assistant, Quin, draws on customer history, product usage, conversations, meetings and workflows already in Vitally. It answers questions, drafts emails and updates CRM fields. Its AI-powered meetings feature captures summaries, decisions, risks and next steps, which feed the customer context Quin works from.

Best for: teams that want the CS platform and meeting notes from one vendor.

Gong: churn risk from conversations

Gong's customer success page says it flags churn risk by analyzing customer sentiment, ghosting and stakeholder changes, and gives CROs visibility into renewal and expansion forecasts. Its help center describes Ask Anything, which answers plain-English questions about a deal or account from up to 60 calls and 500 emails. Gong works with Gainsight and ChurnZero. That page does not describe live help during calls.

Best for: companies already on Gong for sales that want post-sales teams on the same conversation data.

Avoma: renewal briefs and answer cards

Avoma says it tracks renewal signals in customer calls and flags renewal risk 90 days out with the evidence, and prepares a renewal brief covering the customer's goals, results, risks and plan. Its real-time guidance shows admin-approved answer cards on the rep's screen when trigger phrases come up, such as pricing questions or competitor mentions; each card stays visible for 20 seconds. Its help center says the cards are visible only to reps and never shown to external participants.

Best for: cost-conscious teams that want meeting notes, renewal risk and keyword-triggered answer cards from one vendor.

Fathom: low-cost notes and search

Fathom summarizes meetings, captures action items and lets you search past meetings with Ask Fathom. Its Business plan adds CRM field sync and Deal View. It works with Zoom, Google Meet and Microsoft Teams, with a bot-free capture option.

Best for: small CS teams that mainly need reliable notes and follow-ups at a low price.

Which combination fits your CS team?

How should you evaluate an AI tool for renewal calls?

1. Run it on a real renewal. Pick an account renewing next quarter, ask for a brief and check every fact.

2. Ask where each answer came from. An answer without a source is hard to trust on a contract call.

3. Check who sees what. For in-call help, confirm that prompts appear only on the CSM's screen and that the customer sees a normal meeting and the recording notice.

4. Test pricing and contract questions. Load your price book and standard terms, then ask what customers actually raise at renewal. A wrong number is worse than no answer.

5. Confirm write-back. Notes, risks and action items should reach your CRM or CS platform after a person approves them.

6. Price the real usage. Per-seat, per-recorder-seat and per-call-hour pricing give very different totals for a CS team.

Where Proshort fits (and where it does not)

Proshort fits when the renewal is won or lost on the call itself. Aria Live gives the CSM sourced answers to pricing, contract and product questions during the call, tracks every concern raised until it is resolved, and drafts the follow-up afterwards. Aria Live costs $3 per call hour, only on the calls you choose, so a CSM can turn it on for renewals and QBRs. See Proshort for customer success.

"Proshort gave our reps something they didn't have before: context going into every call, without any extra work." Deepak PG, Senior Director Sales Operations, MetricStream

Read the MetricStream case study. Proshort is not a customer success platform. If you need product-usage health scores, success plans and renewal forecasting, keep or choose a platform such as Gainsight, ChurnZero or Vitally and run Proshort alongside it. If your CSMs only need notes from routine check-ins, a notes tool will cost less.

Frequently asked questions

What is the best AI tool for customer success managers?

It depends on the gap. For health scores, success plans and renewal forecasting, choose a CS platform such as Gainsight, ChurnZero or Vitally. For capturing and analyzing calls, Gong, Avoma or Fathom. For help during the renewal call itself, Proshort's Aria puts sourced answers on the CSM's screen while the customer talks. Many teams run one of each.

Can AI help a CSM during a live renewal call?

Yes. Proshort's Aria Live joins Zoom, Google Meet or Microsoft Teams and shows the CSM the answer, the proof point and the next question as the customer asks, with the source shown and visible only to the CSM. Avoma also describes keyword-triggered answer cards that appear on the rep's screen during a call and are never shown to external participants.

Do customer success platforms like Gainsight and ChurnZero help during calls?

Their sites describe AI that works on account data: Gainsight's Risk Analyst and Expansion Analyst agents, ChurnZero's Kit assistant and Vitally's Quin. Vitally also captures meeting summaries, decisions and risks. None of the three describes help during the call on its site as of November 2026, so most teams pair the platform with a call tool.

How much do AI tools for customer success cost?

Gainsight, ChurnZero and Vitally do not publish prices. Fathom has a free plan and team plans from $15 per user per month, and Avoma starts at $19 per recorder seat (both billed annually). Proshort costs $75 per rep per month plus $3 per call hour for Aria Live. Gong publishes no prices; estimates put it at $1,360 to $1,600 per user per year at list plus a platform fee.

What should a CSM prepare before a renewal call?

Confirm who will attend and what changed since the last meeting. List every commitment your team made and its status, review usage and support trends, and note risk signals such as a quiet champion or a new decision-maker. Then load current pricing and standard contract terms so the answers you give on the call are accurate.
