SIMY is an AI development platform built to reduce the gap between team conversations and implementation. It turns discussions from Slack, meetings, Gmail, and other workplace tools into structured engineering context, then uses that context to generate code, tests, and GitHub pull requests.

We built SIMY from a problem we kept seeing in our own work: a team discusses a feature, everyone seems aligned, but once implementation starts, the intention shifts. Assumptions no longer match, edge cases get missed, and the final PR gets feedback like, โ€œusers wouldnโ€™t actually use this.โ€

The issue is often not lack of effort. It is that the assumptions inside the conversation never fully make it into the code. PMs may optimize for user value, while engineers optimize for correctness and safety. Both are reasonable, but the same words can still mean different things in practice.

Traditional fixes like writing better specs rarely work as cleanly as they sound. Specs are often incomplete, outdated, or never written at all, while Slack and meetings remain the real source of truth.

Most coding tools assume a human has already translated the discussion into a clean prompt or specification. SIMY is designed to remove that translation step. It uses the conversation itself as the input, reconstructs the relevant context, makes the done state explicit, and generates implementation from that shared understanding.

In internal benchmarks, SIMY achieved 86.7% first-shot success and increased pull requests per engineer by 17.7x on tested tasks. These are early internal results, and real-world performance will vary.

SIMY is currently connected to the Claude Code API, with support for additional backends planned over time. It is still early, and we are especially interested in feedback on where this breaks down in real teams.

Questions & Answers

As answered by people managing Windsurf Editor and SIMY.one.

What makes your product unique?

SIMY.one's answer:

SIMY uses real team conversations as the source of truth for software development. Instead of relying on manually written prompts or specs, it captures context directly from Slack, meetings, and emails, reconstructs intent, and generates code, tests, and pull requests from that shared understanding.

Why should a person choose your product over its competitors?

SIMY.one's answer:

Most AI coding tools require developers to translate discussions into prompts. SIMY removes that step. By working from original conversations, it reduces misalignment, avoids lost assumptions, and produces outputs that better reflect what the team actually decided.

How would you describe the primary audience of your product?

SIMY.one's answer:

Product and engineering teams building software collaborativelyโ€”especially teams that rely heavily on Slack and meetings and want to reduce friction between decision-making and implementation.

What's the story behind your product?

SIMY.one's answer:

SIMY was built from repeated experiences where teams aligned in discussions but diverged during implementation. Feedback like โ€œthis isnโ€™t what users needโ€ often came from assumptions that never made it into the code. SIMY was created to close that gap by making conversations directly executable.

Which are the primary technologies used for building your product?

SIMY.one's answer:

AI agents, large language models (via Claude Code API), cloud infrastructure, and integrations with collaboration tools (Slack, Teams, Gmail, Zoom) and GitHub.

Who are some of the biggest customers of your product?

SIMY.one's answer:

SIMY is currently in an early pilot phase and has not publicly disclosed customer names.

Windsurf Editor Reviews

Cursor vs Windsurf vs GitHub Copilot
Now, don't get me wrong, both Windsurf and Copilot are solid tools. Copilot is great for quick suggestions across different IDEs, and Windsurf impresses with its polished UI and intuitive workflow. Windsurf's Cascade feature even offers sophisticated real-time collaboration, comprehensive project understanding, and seamless context awareness that rivals Cursor's capabilities.

SIMY.one Reviews

  1. Stress-free for both executives and engineers.

    As a user, I had the opportunity to contribute to the development of SIMY.

    Perhaps due to the systemโ€™s complexity, there are still some bugs, but it has become much more stable over time. What impressed me most is the concept: capturing conversations from Slack, Gmail, Zoom, Teams, and more, then using AI to automatically create and update actions. Additionally, incorporating historical action data as contextual input for coding is a brilliant idea.

    For these reasons, Iโ€™m giving it 5 stars.
