Gong is a leader in conversation intelligence, but many teams now prioritize in-call, real-time guidance over post-call analytics alone. If you want software that helps reps in the moment with context-aware prompts, these five alternatives are the strongest options to evaluate in 2025.
Methodology, at a glance We prioritized platforms that:
- Deliver live prompts in-call for objections, pricing, and competitor mentions.
- Learn from your top calls to keep prompts fresh and relevant.
- Provide governance and measurable impact via tracked usage and outcomes.
Why real-time matters: A large field study from Stanford HAI found AI assistance increased agent productivity by ~14 percent, with the biggest gains for less experienced reps — strong evidence that in-flow guidance can move the needle. Read the summary.
#1 Nomi.so — Best for a "Living Playbook" inside the call
What it does Nomi is purpose-built for one job: providing the absolute best real-time, in-call coaching experience. While other platforms add real-time features to an analytics suite, Nomi's entire architecture is designed to surface the right words at the right second. It achieves this through what it calls a Living Playbook, which automatically learns from your top performers and delivers their winning talk tracks as live suggestions to the entire team.
Why consider it
- Laser-focused on live guidance: Its core strength and entire focus is on the in-call experience.
- Auto-builds and updates playbooks: Minimizes admin time by learning directly from calls.
- Clean, intuitive UX: Designed for reps to adopt quickly without friction during live conversations.
Mind the fit Nomi is not a heavy post-call analytics suite like Gong. It's designed for teams who have decided that their primary bottleneck is inconsistent execution during the call and want a dedicated tool to solve that specific problem with maximum impact.

#2 Clari Copilot — Best for an All-in-One Revenue Platform
What it does Clari Copilot (formerly Groove) blends conversation intelligence with a broader revenue platform that includes forecasting and pipeline management. It offers real-time call guidance as part of a larger suite of "RevOps" tools.
Why consider it
- Unified Platform: Combines coaching with pipeline and forecasting tools.
- Deep Ecosystem: Integrates tightly across Clari's entire revenue platform.
Mind the fit Ideal if your primary goal is to consolidate vendors and have coaching tied closely to pipeline hygiene and forecasting within a single stack. The real-time coaching is a feature, not the entire product focus.

#3 Outreach Kaia — Best Embedded Assistant for Outreach Users
What it does Outreach Kaia (Knowledge AI Assistant) joins meetings live to help reps handle objections and answer questions by surfacing content cards. It also captures summaries and action items after the call.
Why consider it
- Native Integration: Perfect for teams already running their entire sales motion on Outreach.
- Content-driven: Excels at surfacing existing sales collateral (battle cards, FAQs) in real-time.
Mind the fit The deepest value is unlocked if Outreach is your primary operating system for prospecting and meetings. It's less of a fit for teams using a different sales engagement platform.

#4 Cresta — Best for Enterprise Contact Centers
What it does Cresta is a powerful real-time intelligence platform that started in the contact center and has expanded to sales. It excels at agent assist, with prompts, precise answers, and AI summaries across multiple channels (voice, chat).
Why consider it
- Mature Agent-Assist: A very deep feature set designed for complex, high-volume organizations.
- Multi-channel: Extends real-time guidance beyond sales calls to include chat and service interactions.
Mind the fit A strong choice for large enterprises that want a unified real-time assist platform across both sales and customer service departments. It may be too complex for smaller, sales-only teams.

#5 Salesken — Best for Rapid Rollout in SMB & Mid-Market
What it does Salesken provides a combination of real-time AI assistance and post-call conversation intelligence. It offers live prompts for objections, competitor mentions, and key talking points.
Why consider it
- Emphasis on Live Coaching: A core part of their value proposition is in-call guidance.
- Balanced Feature Set: Provides a good mix of live prompts and post-call analytics for teams that want both.
Mind the fit Well-suited for SMB or Mid-Market teams that want to get started quickly with a balanced platform for both live cues and post-call insights.

FAQ
Is real-time coaching a replacement for post-call analysis?
No. Post-call analysis informs what goes into your Living Playbook. Real-time coaching operationalizes those insights during the conversation.
Are these tools only for enterprise?
No. Nomi and Salesken work well for SMB to mid-market teams, while Clari Copilot and Cresta often serve larger or more complex environments. Outreach Kaia shines if you are already on Outreach.
How can we validate impact quickly?
Track leading indicators first — prompt show rate, accept rate, time to handle objections — then monitor stage conversion and cycle time. For why in-flow assistance can move productivity, see Stanford HAI's field study summary. Read it.
