Revo is built for leaders and teams who operate across many signals including emails, meetings, chats, documents, and metrics. Instead of optimizing a single surface, Revo connects context across your entire company and turns it into structured intelligence, making it a powerful AI email assistant for teams and a true cross platform AI assistant.
While Jace focuses on email drafting and inbox management as an "AI Chief of Staff," Revo goes deeper. It understands why a message matters, how it connects to ongoing work, and what decisions or actions should follow. Emails are just one signal among many, not the whole story, which is why teams comparing Revo vs Jace or searching for the best Jace alternative often prioritize deeper context and business wide intelligence over simple AI inbox management.

See the difference
Same email. Two AI tools. Watch what happens when one knows your business, and one doesn't.
Jace is a capable inbox tool and AI email assistant, but it has real limitations that become obvious once you need more than basic email triage and simple AI inbox management. For teams comparing Revo vs Jace, researching Jace reviews, or looking for the best Jace alternative, these limitations matter when choosing an AI email assistant for teams that require deeper context and cross-platform intelligence.
Limited cross-platform support
While Jace has recently added Outlook support in open beta, it remains primarily Gmail-focused. Organizations using other email providers or requiring full multi-platform functionality may find limitations.
Revo works across email platforms and connects to your full business context regardless of which inbox you use.
Limited email history access
Jace's chat functionality on the standard plan only allows interaction with emails from the past 30 days. The Pro plan extends this to 3 years, but requires a higher-tier subscription. If you need to reference older conversations, client history, or long-running projects on the basic plan, you're limited.
Revo connects your full communication history with your CRM, documents, and business context, no artificial time limits.
Generates unnecessary drafts
Users report Jace generates drafts for low-value system emails like auto-generated calendar notifications. This creates noise instead of reducing it.
Revo understands business context and prioritizes what actually matters.
No team workspace support
Jace operates through personal Gmail/Calendar accounts only. There's no shared team workspace, meaning collaborative email management isn't possible.
Revo is built for teams, connecting signals across your entire organization.
Customer service concerns
Multiple reviewers have reported customer service issues, including disputes over misleading pricing information and unprofessional communication from staff.
Revo offers enterprise-grade support wit h dedicated account management and transparent pricing.
Ready for an AI that actually knows your business?
Jace is fine for basic Gmail inbox management. But if you need context-aware intelligence across your entire workflow, with drafts you can trust and team coordination, Revo was built for you.

FAQ

This is where Revo leaves other tools behind. Revo doesn't just "search" your tools when you get an email. Instead, it builds and maintains Intelligence Modules—a living memory of your company that updates in real-time.
The Difference: Revo already knows the status of every project, the decision made in this morning's meeting, and the latest Slack update before you even open your inbox.
Example: When a client asks, "Is the bug fixed?", Revo doesn't have to go look it up. It already knows the fix was shipped in v2.4 this morning and drafts the confirmation instantly based on that verified fact.
No human at Revo ever reads your emails. Revo is an automated infrastructure. We use secure APIs (the same ones Gmail/Outlook use) to structure context—like identifying a project deadline—and draft your reply. We are SOC 2 and ISO 27701 compliant and certified, and your data is siloed. It is never used to train public AI models. You own your data, period.
Absolutely. While Revo makes you faster individually, it makes teams significantly smarter. When your team uses Revo, you build a Shared Intelligence. Your drafts can reference context from a meeting your co-founder had, or a ticket your engineer just closed, ensuring everyone speaks with one unified voice.
Yes, if you want it to. Revo includes a high-fidelity Meeting Recorder that joins calls (Google Meet, Zoom, Teams) to capture decisions and action items. This "Meeting Intelligence" is instantly fed into your context modules, so your email drafts normally know what was discussed 5 minutes ago without you typing a summary.
