Mailyr
What is Mailyr?
Mailyr writes Gmail drafts from a subject line inside a Chrome extension, so you never leave your inbox to open a separate chat window. Open the composer in Gmail, type a subject, pick a tone and length, and the extension inserts a full draft you can edit before sending.
Compared with generic writing assistants, Mailyr stays inside Gmail and optimizes for outbound email speed rather than long documents. The free Starter tier runs on mid-tier models like GPT-4o mini and Gemini Flash with 14 complimentary credits, while Premium at $4.90 per month unlocks GPT-4o, Claude Sonnet, and 250 generated emails with faster throughput and priority support.
Busy professionals, founders, and support reps use Mailyr when they answer dozens of similar emails daily and want grammar-checked drafts without copying text between tabs.
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.
