What makes your product unique?

GraphComment's answer

GraphComment is the only WordPress comment system that blocks spam structurally: it closes the native comment endpoint so bots are stopped at the source, not just filtered — no CAPTCHA for your readers. AI-assisted moderation is included on every plan, even the free one. And unlike hosted platforms, every comment syncs back into your own WordPress database, so you never lose your data. No ads, no tracking, EU-hosted and GDPR-compliant.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Why should a person choose your product over its competitors?

GraphComment's answer

Compared to Disqus, GraphComment shows no ads and never monetizes your readers' data. Compared to wpDiscuz, features like AI moderation, customization, themes and dark mode are included rather than sold as paid add-ons. You get structural anti-spam, AI-assisted moderation on every plan, near-native Core Web Vitals, and full ownership of your comments in your WordPress database. The free plan includes every feature; paid plans start at $29/mo.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

How would you describe the primary audience of your product?

GraphComment's answer

Publishers and website owners who want an engaged, well-moderated comment section without spam, ads or tracking — from independent blogs and mid-sized WordPress sites to news media handling large comment volumes. It fits anyone who takes reader discussion seriously and wants to keep control of their data.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

GraphComment's answer

GraphComment was built to solve comment moderation and spam at scale for online media. The same infrastructure that powers comment sections handling millions of comments a month for national media is now available to every WordPress site — with structural anti-spam and AI-assisted moderation included.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Which are the primary technologies used for building your product?

GraphComment's answer

GraphComment is a cloud (SaaS) platform: a lightweight JavaScript widget that embeds on any website, plus an official WordPress plugin (PHP). The backend runs on Node.js with a real-time layer for live updates, and AI moderation combines large language models with a contextual analysis layer. Hosted in the EU.

Diffyn's answer:

React, Next.js, POSTGRESQL
