Features and specs

What each product offers, as listed by its team.

replit 6 features
Diopter 5 features
  • Ease of Use
    Replit offers an intuitive interface that makes it easy to start coding without needing to set up development environments. This can significantly lower the barrier to entry for beginners.
  • Collaborative Coding
    Replit facilitates real-time collaboration, allowing multiple users to work on the same codebase simultaneously, similar to tools like Google Docs.
  • Supports Multiple Languages
    Replit supports a wide range of programming languages including Python, JavaScript, C++, and many more. This makes it flexible for users with different needs.
  • Cloud-Based
    Being a cloud-based platform, Replit enables users to access their code from any device with an internet connection, eliminating the need for local storage.
  • Built-in Package Manager
    Replit comes with built-in package managers for various languages, making it easier to include third-party libraries and dependencies.
  • Educational Tools
    The platform offers various resources for educators, such as interactive coding environments and classroom management tools, making it ideal for academic settings.

Possible disadvantages

  • Performance Limitations
    Being a cloud-based IDE, Replit may encounter performance issues for larger projects or those requiring intensive computational resources.
  • Limited Customization
    The environment may lack some customization options and advanced settings available in traditional, locally-installed IDEs.
  • Dependency on Internet
    Since it's cloud-based, an active internet connection is mandatory for coding, which can be a drawback in situations with unreliable internet access.
  • Privacy Concerns
    Hosting code on a third-party platform may raise privacy and security issues, especially for proprietary or sensitive projects.
  • Subscription Costs
    While Replit offers a free tier, advanced features, higher resource limits, and premium support come at a subscription cost, which may be a barrier for some users.
  • Limited Debugging Tools
    The platform's debugging tools may not be as robust as those available in more established, dedicated IDEs.
  • AI-Powered Code Review
    Diopter leverages artificial intelligence to automate and enhance code review processes, potentially catching issues faster than manual review alone.
  • Integration Capabilities
    The tool is designed to integrate with existing development workflows and version control systems, making it easier to adopt without disrupting current processes.
  • Time Efficiency
    By automating parts of the code review process, Diopter can help development teams save time and accelerate their software delivery cycles.
  • Consistency in Reviews
    AI-driven reviews can provide consistent feedback based on predefined rules and patterns, reducing variability that might occur with different human reviewers.
  • Scalability
    As an AI-based solution, Diopter can potentially scale to handle large codebases and high volumes of pull requests more efficiently than manual review processes.

Questions & Answers

As answered by people managing replit and Diopter.

What makes your product unique?

Diopter's answer:

Diopter scores the live call, not a file after the fact. Most detection tools ask you to upload media and wait for a verdict. Diopter runs alongside a Zoom, Microsoft Teams, Google Meet or Webex call and scores every participant continuously for the full length of the call, including someone who is not speaking.

It also combines four signals rather than one. Video deepfake detection, audio deepfake detection, identity and payment verification, and policy alignment resolve into a single recommended action, so a security or finance team gets one decision rather than four dashboards.

The verdicts are deliberately honest. Bands are AI, mixed, clean and inconclusive, each with a confidence level rather than a flat yes or no. If a call could not be fully checked, Diopter reports that rather than defaulting to clean. It does not identify who is speaking, uses no voiceprints or enrollment, and never treats accent, region or language as a signal.

Why should a person choose your product over its competitors?

Diopter's answer:

Because the attack happens on the call, and that is where Diopter works.

Identity verification tools check a person once, usually at onboarding or account recovery. That does nothing for a wire approval call three months later where the person on screen is a deepfake. Single-frame or file-based detectors judge a moment of media rather than the conversation shaping the ask.

Diopter runs for the whole call and scores every participant continuously, on Zoom, Microsoft Teams, Google Meet and Webex, and on VoIP and conference phone calls through Zoom Phone, Teams Phone, RingCentral and Dialpad. It combines synthetic media detection with identity and payment verification and policy alignment, then returns one recommended action.

It is also straightforward to deploy and clear about its limits. No caller-side install, works with a meeting bot or bot-free, on-prem and hybrid supported, configurable retention including zero data retention, and rollout through existing MDM such as Intune and Jamf. SOC 2 Type II in progress.

How would you describe the primary audience of your product?

Diopter's answer:

Security and fraud teams at organisations where a phone or video call can move money, grant access or hire someone.

The people who buy and run it are CISOs and security operations, fraud operations, and IT. The people it protects usually sit elsewhere in the business: finance and treasury staff approving wires, accounts payable teams handling vendor payment changes, recruiters and hiring managers interviewing candidates, executive assistants fielding urgent requests, and IT help desk agents resetting credentials.

The common thread is a live conversation where someone is asking for something consequential and the only proof of who they are is their face or their voice.

What's the story behind your product?

Diopter's answer:

Diopter was founded in April 2026 by Rohan Gupta and Jeremy Pippin, after they watched generative AI move from productivity use cases into impersonation, fraud and social engineering.

Both came from QuillBot, where Rohan was founder and CEO of a generative AI company with more than 35 million monthly users, and Jeremy was VP of Product, having previously held the same role at FanDuel. They had spent years on the building side of generative AI and could see how cheap and scalable the attack had become while defence stayed expensive and manual.

The belief that shaped the product is that fraud is rarely detectable from a single frame or voice sample. It unfolds across a conversation, so the arc is the unit of analysis: authority, urgency, isolation, escalation and the ask, scored continuously through a live call.

The company is based in Chicago, Illinois.
