Remail

What is Remail?
Remail drafts and replies to Gmail messages from a Chrome extension and web app, pulling context from the thread plus your knowledge base when you need a fast answer. Pick positive or negative quick replies, set a tone, or type a short prompt and get multiple draft options you can send without rewriting from scratch.
Unlike single-purpose email writers, Remail bundles an AI sidebar, PDF and YouTube chat, LinkedIn post tools, and side-by-side LLM comparison in one browser extension. That breadth targets people who want email help without opening a separate chat tab for every task.
The product lists 210,000+ users and a 4.9 rating on the Chrome Web Store, with Gmail extension and Google Workspace marketplace listings. Pro starts at $19 per month with 6,000 queries; a 7-day free trial is available before you commit.
Opnbx.ai

What is Opnbx.ai?
Opnbx.ai is a B2B sales intelligence platform built around what the company calls Precision Prospecting. It gives sales and marketing teams a unified data layer to spot which accounts in their market are worth pursuing right now. The product focuses on ICP validation, intelligent segmentation, and account-level research rather than generic firmographic lists. Teams log in through app.opnbx.ai after booking a demo through the marketing site.
Most intent data vendors sell broad market signals that every competitor can buy. Opnbx.ai tries to correlate signals from your own closed-won deals with live account activity, then scores and prioritizes companies against that custom model. The homepage positions it as a replacement for stitching together a Franken-Stack of tools like 6sense, Clay, Bombora, and ZoomInfo. That trade-off is narrower fit modeling in one platform instead of buying the same commoditized feeds everyone else has.
It targets sales leaders, RevOps teams, and individual reps at B2B companies running outbound or pipeline development motions. Integrations listed on the site include Outreach, HubSpot, Salesforce, Salesloft, and Apollo.io. Customer testimonials on the homepage come from teams at Datavolo, Vial, Descope, and Pangia who cite faster account research and higher conversion rates after onboarding.
