Features and specs

What each product offers, as listed by its team.

Velvr.app 8 features
SharpKeys 6 features
  • AI Auto-Reply
    Replies to every fan message automatically in your persona's voice — 9 archetypes plus a tone slider
  • Transparent 5-Phase Funnel
    Every fan tracked P1–P5; the inbox shows each fan's phase and what the engine will and won't offer next
  • Mechanical Compliance
    6 deterministic server-side validators on every reply, incl. EU AI Act Art. 50 disclosure and hard limits the AI can't override
  • Adaptive PPV Upselling
    Offers paid content only when a fan's message signals interest — never on a timer, never to everyone at once
  • Multi-Persona, One Account
    Run multiple personas in one account with strict data isolation between them
  • 14-Language Translator Mode
    Deterministic language switch via a numbered menu, not fragile auto-detection
  • Native Fanvue Billing
    Subscriptions through the official Fanvue App Store, hard-capped usage — no surprise overages
  • Privacy-First
    Does not train AI models on customer data
  • Open Source
    SharpKeys is available on GitHub, which means it is open source. This allows users to inspect the code, contribute to development, or customize it for their needs.
  • Free of Cost
    SharpKeys is entirely free to use, making it accessible to anyone without the need for a commercial license.
  • Simple User Interface
    The interface is straightforward and easy to use, which makes the process of remapping keys simple even for non-technical users.
  • Registry-Based Remapping
    SharpKeys makes changes directly to the Windows registry, ensuring that the remapped keys work across all applications without the need for additional software running in the background.
  • Minimal Resource Usage
    Because SharpKeys modifies the registry rather than running a constant background process, it uses minimal system resources.
  • Portability
    Once the registry changes are made, SharpKeys does not need to remain installed on the system, making it a lightweight, one-time-use tool.

Possible disadvantages

  • Windows Only
    SharpKeys is designed to work exclusively on Windows operating systems, which limits its usability for users on macOS, Linux, or other platforms.
  • Limited to Registry
    The tool operates by modifying the Windows registry, so it cannot handle complex remapping scenarios that need real-time processing, such as conditional key mappings.
  • No Advanced Features
    SharpKeys lacks advanced features found in more sophisticated key remapping software, such as macro recording, multi-key remapping, or application-specific profiles.
  • Requires Admin Rights
    Since changes are made to the Windows registry, administrative privileges are required, which might be restrictive in some organizational environments.
  • Potential for Errors
    Incorrect registry changes could potentially lead to system instability or errors, especially for users who are not familiar with the Windows registry.
  • Reboot Required
    For registry changes to take effect, a system reboot is necessary, which can be inconvenient for users needing immediate results.

Why this product is good

  • SharpKeys is a utility that allows users to remap keys on their Windows keyboards. It modifies the Windows Registry to achieve this, which is particularly useful for users who want to change the function of a specific key, disable a key, or swap keys to better match their personal typing preferences or overcome keyboard limitations.

Recommended for

    SharpKeys is recommended for Windows users who need to customize their keyboard layout, such as programmers, writers, or anyone who frequently uses specific key combinations. It is also suitable for users who want to disable keys that are accidentally pressed often, such as Caps Lock or Insert, as well as those who want to swap keys for ergonomic reasons or due to a damaged key on their keyboard.

Questions & Answers

As answered by people managing Velvr.app and SharpKeys.

What makes your product unique?

Velvr.app's answer

Velvr is the only Fanvue tool where compliance is mechanical, not prompt-based: every AI reply passes six deterministic server-side validators before it's sent — including a mandatory EU AI Act Article 50 disclosure on the first reply and hard limits the AI cannot override. It pairs that with a transparent 5-phase fan funnel you can inspect per fan, and true multi-persona isolation within a single account.

Why should a person choose your product over its competitors?

Velvr.app's answer

Most Fanvue AI tools rely on prompts and probabilistic judging. Velvr guarantees output compliance with deterministic, audit-logged validators, shows the engine's decision state transparently for every fan (no black box), and is Fanvue-native by design — every engineering hour goes into Fanvue depth, not platform breadth. Pricing is flat with hard usage caps and no revenue share.

How would you describe the primary audience of your product?

Velvr.app's answer

Fanvue creators and the operators and agencies who run them — from solo creators to multi-persona operators managing several personas from one account.

What's the story behind your product?

Velvr.app's answer

Velvr grew out of running a live AI-chat operation on Fanvue. Several rounds of prompt-hardening proved that prompts alone can't keep an AI reliably compliant, so we rebuilt the system around mechanical, server-side validators. That became Velvr's core idea: an adaptive engine with a transparent funnel and compliance guaranteed in code, not left to creator discipline.

Which are the primary technologies used for building your product?

Velvr.app's answer

Built on Next.js and TypeScript with a PostgreSQL backend, cloud-hosted, with durable background workflows. AI replies run on large-language-model APIs, always behind Velvr's deterministic server-side validators.

    You can remap the keys so that "Special: Power" key button does nothing.. Or even to the original function (on my keyboard it would mean Volume Down would be F12 instead). One Windows software to do that:... - Source: Hacker News / 4 months ago
