Exhibit 99.1

Myseum.AI Highlights Continuing Progress on

AI Development Roadmap, Technology Advancements and Growth Initiatives in Letter to Shareholders

CEO Darin Myman highlights latest developments

for privacy-first, localized agentic AI platform supporting social media platforms

Myseum.AI’s core mission is to become

the trusted infrastructure layer for privacy-centric media intelligence

NEW BRUNSWICK, N.J., May 18, 2026 (GLOBE NEWSWIRE) – Myseum.AI,

Inc. (Nasdaq: MYSE) (“Myseum.AI” or the “Company”), a privacy-first AI and social media technology company, today

issued a shareholder letter by CEO Darin Myman detailing corporate progress, AI development, and the strategic roadmap for the “Picture

Party by Myseum.AI” next-gen social sharing platform launched in January 2026.

Dear fellow shareholders,

With our recent corporate name change to Myseum.AI, I want to take

a moment to reflect on our Company’s strategic technology initiative in agentic AI, share key business developments, and reveal

our plans for positioning our DatChat and “Picture Party by Myseum” social media platforms to capitalize on the widespread

need for content privacy and social media that solves challenges not addressed by current market offerings.

Privacy-First, Localized Agentic AI Platform

Users are currently demanding more AI powered experiences, while at

the same time they increasingly distrust centralized data collection. Myseum.AI is developing a privacy-first, localized agentic AI platform

that enables social media and digital media platforms to deliver intelligent photo, video, and messaging experiences without compromising

user privacy. The platform allows AI models to operate locally on-device or within secure edge environments, training directly on user-owned

content—including photos, videos, messages, voice notes, and media metadata—to power advanced personalization features while

maintaining user control and data sovereignty.

Myseum.AI’s core mission is to become the trusted infrastructure

layer for privacy-centric media intelligence.

Unlike traditional cloud AI systems that centralize sensitive user

data, Myseum.AI is developing localized inference and federated learning architectures to minimize data exposure. At the same time, those

architectures enable continuous enhancements to AI experiences that help users manage content and create media libraries without sacrificing

privacy and control. New features for our social media platforms may include agentic media assistants that autonomously organize and curate

user content for smart albums and memory creation, automate photo and video tagging, and more.

Accelerating Development with AI

Integrating Claude AI with our in-house development team has significantly

accelerated our platform development. Picture Party by Myseum.AI has moved from core capability development to user experience enhancements

through new features such as moderation tools, organizational tools and new experiential offerings. Additionally, we have successfully

launched our affiliate program and are making significant progress in the wedding space.

Marketing

Myseum.AI recently announced the appointment of Ian Goldberg to head

marketing, partnerships and monetization. Ian Goldberg is the former founder and CEO of iSport360, a youth sports technology and media

company, which was acquired by Signature Athletics in 2025. In his role, Goldberg launched, scaled and monetized the youth sports content

platform, reaching an audience of 3.5 million parents and coaches. An early innovator in digital marketing, Ian’s playbook uses content

and storytelling to quickly and cost-effectively scale tech-enabled brands.

Patent Portfolio

Myseum’s IP portfolio now includes 20 issued patents, and several

filed domestic and international patent applications. Our strong and growing intellectual property is powering our ongoing technology

development and platform expansion.

Right Place, Right Time

We are currently in a time where mistrust of social media platforms

and privacy concerns are growing exponentially. There is a rising dissatisfaction with how users are bombarded with advertisements and

nearly blatant disregard for our privacy and how our information is used. Our team believes we are in the right place at the right time

with a platform and technologies that are needed now more than ever. Most importantly, we have positioned Picture Party as much more than

a privacy platform — it makes it easier, more secure and more useful to use social media on based on users’ terms. Our focus

on privacy-first AI and social media puts Myseum.AI on what we see as a clear path to success for both our Company as a pioneer in privacy

and social media technology, and our fellow shareholders as valued partners in our future accomplishments.

Sincerely,

Darin Myman

Chief Executive Officer
