See the difference
Same email. Two AI tools. Watch what happens when one knows your business, and one doesn't.
Not every “smart inbox” feature actually helps your team get work done. Here’s where Shortwave hits limits.
Paywall-Gated Features
Some essential features, like read receipts, are only available on higher-tier plans.
Revo gives core intelligence across all plans.
Limited AI Customization
You can’t teach Shortwave to reflect your team’s tone or priorities.
Revo adapts to your business style automatically.
No Cross-Platform Workflow
Shortwave is Gmail-only, so switching between tools breaks your workflow.
Revo integrates across email, Slack, and project tools.
No Persistent Team Memory
AI forgets context outside recent threads.
Revo retains knowledge across projects, deals, and team conversations for smarter replies.
Email Automation That Actually Moves Your Business Forward
Shortwave speeds up replies, but Revo turns emails into tasks and actionable follow-ups across your team.
.avif)
Shortwave is handy for inbox speed but falls short on business context and team workflows.

Where Revo Wins
With Intelligence Modules, your inbox understands real team context across Slack, Jira, CRM, and meetings – not just a single thread.
Compare Revo to other tools.
Domande Frequenti
Hai domande? Abbiamo risposte di esperti per guidarti in ogni fase.
Yes, but only if you choose to enable it.
Revo includes a high-fidelity AI Meeting Recorder that joins Google Meet, Zoom, and Microsoft Teams calls to capture decisions, summaries, and action items.
That meeting intelligence is instantly added to your context, so when you open your inbox five minutes later, your email drafts already reflect what was discussed.
It is not a manual recap or copy-paste. Just seamless follow-through.
Absolutely! Individually, Revo makes you faster. As a team, it makes you smarter.
When your team connects their inboxes and tools, Revo builds Shared Intelligence. That means your draft can reflect context from a meeting your co-founder had, or a ticket your engineer just closed. You won’t be asking around for context.
It keeps everyone aligned, consistent, and on the same page across sales, ops, and product.
It literally takes about 30 seconds.

That’s it.
There’s no software to install. No Chrome extension. No new inbox to learn. Revo runs quietly in the background as your email automation tool. All you have to do is open Gmail or Outlook and your drafts are already waiting.
Yes. Revo works anywhere your email works.
Because it runs directly inside Gmail and Outlook, there’s nothing new to download. Just connect your account once, open the Gmail or Outlook app on your phone, and your AI-generated drafts will already be there, ready for you to review and send.
It’s a true native AI email assistant, not another app that you have to manage.
No, no human at Revo ever reads your emails.
Revo operates as secure, automated infrastructure. It uses the same encrypted APIs as Gmail and Outlook to structure context (like deadlines or project updates) and generate accurate drafts.
We’re SOC 2 Type II and ISO 27701 certified, fully compliant, and your data is completely siloed. It’s never used to train public AI models.
Just remember: You own your data. Always.
Revo doesn’t just search Slack or Jira when an email comes in. It builds Intelligence Modules.
No regular resets, but a real-time memory of your company that stays continuously updated.
Before you even open an email, Revo already understands project status, recent decisions, and the latest updates across your tools.
So when a client asks, “Is the bug fixed?”, Revo doesn’t scramble to look it up. It already knows the fix shipped in v2.4 this morning and drafts a reply based on verified context.
That’s the difference between a basic email AI and a true context-aware email automation tool.
