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 Specs are often incomplete, outdated, or never written at all, while Slack and meetings remain the real source of truth.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.

Possible disadvantages of BitBucket

  • User Interface
    Some users find BitBucket's user interface less intuitive compared to competitors like GitHub and GitLab, which can lead to a steeper learning curve for new users.
  • Performance Issues
    There can be occasional performance issues, particularly with larger repositories or heavy traffic, which can slow down the development and deployment processes.
  • Smaller Community
    BitBucket has a smaller user community compared to GitHub, which may result in fewer third-party integrations, plugins, and community-driven support resources.
  • Limited Marketplace
    The BitBucket Marketplace offers fewer integrations and extensions compared to its competitors, which might limit customization options for advanced users or larger teams.
  • Less Popular for Open Source Projects
    BitBucket is less popular for hosting open-source projects compared to platforms like GitHub, which might be a drawback for teams looking to engage with a broader open-source community.

SIMY.one features and specs

  • Conversation-to-Code Pipeline
    Transforms Slack, meetings, and emails into structured engineering tasks and automatically generates production-ready code and pull requests.
  • Action Database with Done State
    Captures full conversational context (decisions, constraints, edge cases) and defines a clear โ€œdone stateโ€ to align implementation with team intent.
  • Autonomous AI Execution
    AI agents generate code, run tests, and submit GitHub PRs with minimal human input, reducing rework and increasing development velocity.

Questions & Answers

As answered by people managing BitBucket 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.

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.

BitBucket mentions (81)

  • GitHub, Demystified
    One last source of confusion worth clearing up. Git is the version control system itself, the underlying technology that does the change-tracking. GitHub is one popular place to host projects that use Git, and it is not the only one. GitLab and Bitbucket do much the same job. A beginner does not need to evaluate all three. Picking the one a tutorial or a friend already uses is a fine way to start because... - Source: dev.to / about 1 month ago
  • Take control of your job with GitLens Launchpad
    While browsing the web, I came across a feature of GitKraken called Launchpad. This feature enables us to get a big-picture view of all issues and PRs where we are the creator or a follower. If you donโ€™t know GitKraken, it is a Git client with an awesome UI for managing your repositories. You can use it as a desktop app, website, editor extension (GitLens), or the CLI. They have also released an MCP server in the... - Source: dev.to / 7 months ago
  • Integrating Bitbucket MCP with Cursor: A Practical Guide for Developers
    While Cursor supports bugbot for GitHub PR reviews, thereโ€™s nothing similar out-of-the-box for bitbucket users. Setting up Bitbucket MCP with Cursor changed that for meโ€”and made my dev life a lot smoother. - Source: dev.to / 12 months ago
  • GitHub Projects My Way
    I am using GitHub for both personal and work projects. In the past, I used BitBucket, and at some point I considered using GitLab, too. However, the popularity of GitHub and its ecosystem made it hard to ignore. I even use GitHub to follow trends in my profession. - Source: dev.to / about 1 year ago
  • Enhancing Open Source Visibility with License-Token
    Facilitated Collaboration and Funding: With easier identification comes better connectivity. Contributors, partners, and funders can more readily find projects that resonate with their interests and values. Moreover, platforms such as GitHub, GitLab, and Bitbucket are increasingly interested in integrating standardized licensing solutions like License-Token, paving the way for broader adoption and collaborative... - Source: dev.to / over 1 year ago
