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.

ShardStitch's answer:

ShardStitch focuses on recovering the actual project state, not just preserving conversation history. It records verified files, git changes, failed attempts, known constraints, and next steps so coding work can continue after an AI session fails or moves to another tool.

Why should a person choose your product over its competitors?

Diffyn's answer

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

ShardStitch's answer:

ShardStitch is local-first, tool-agnostic, and designed for recovery. It helps developers continue from verified project state across multiple AI coding tools instead of relying on one provider’s chat history or memory system.

Which are the primary technologies used for building your product?

Diffyn's answer

React, Next.js, POSTGRESQL

ShardStitch's answer:

ShardStitch is built around local filesystem and git-state inspection, structured Markdown and JSON recovery packets, deterministic verification, and adapters for supported AI coding tools.

How would you describe the primary audience of your product?

Diffyn's answer

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

ShardStitch's answer:

AI-assisted developers, software engineers, technical leads, and small development teams who use coding agents and need reliable recovery when sessions get stuck, lose context, reach limits, or switch tools.

What's the story behind your product?

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.

ShardStitch's answer:

ShardStitch was created around a practical problem: AI coding sessions can make useful progress but still leave developers unsure what changed, what failed, and how to continue. ShardStitch turns that uncertain handoff into a structured, verifiable continuation process.

Who are some of the biggest customers of your product?

ShardStitch's answer:

ShardStitch is currently used primarily by individual developers, technical practitioners, and small teams experimenting with AI-assisted software development. No enterprise customers are publicly named at this time.
