D&D General I built a free web tool to automate 5e prep (Visual Encounter Graph, Cursed Items, Shops). Looking for veteran feedback!

[Sunday Update] We hit #1! + The "Oracle" Engine is Live!

First off, a huge thank you to this community. Because of your testing and feedback, DM Co-Pilot officially hit #1 on the global AI charts this week!

To celebrate (and to handle the massive 2,700+ user traffic spike), I just pushed a major backend overhaul: The Oracle Engine. >

• Instant Lore Memory: I’ve integrated a global semantic cache. If you generate a common monster or lore prompt, the app now bypasses the "AI thinking" phase and serves the result instantly. Zero lag for your live sessions.

• Knowledge Graph Stability: Fixed the rendering bug on the Lore Web—it’s now fully interactive and draggable for mapping out faction relationships.

Jump in and let me know if the "Instant" generations feel as snappy as they should!

Update: 4,369 Runs & v4.0 Roadmap (VTT Export Incoming!)

Hey everyone, just wanted to drop a quick update and a massive THANK YOU for the feedback.

We just hit a huge milestone: 4,369 automated generations handled by the tool! Because of your testing, DM Co-Pilot is currently the #1 ranked AI app on Viberank.

What’s next? I heard you loud and clear on integration. v4.0 is officially in development, and the headliner feature is the VTT Webhook Hub. You'll soon be able to "blast" any monster or NPC you forge directly into Foundry VTT or Roll20 with one click.

Stay tuned, and keep the critiques coming!

Update: #1 on Viberank & 4,369 Generations! (v4.0 Bridge Incoming)

Quick update for the veterans here: Because of your constant testing and feedback, DM Co-Pilot just hit the #1 spot on the global Viberank charts for AI apps!

We just crossed 4,369 automated generations. To keep up with the demand, I've implemented "The Oracle"—a Redis-backed caching engine to ensure the tool stays fast during your live Sunday sessions.

Next up for v4.0: Direct VTT Webhooks. No more downloading files; just one click to blast your forged lore directly into Foundry or Roll20. Thanks for being the best QA team an indie dev could ask for!

[Update v3.4] The VTT Bridge is officially functional!

Massive thank you to everyone here for the feedback on the previous builds. You asked for a way to move data into your games without the "JSON shuffle," and I’ve delivered.

What's new in v3.4:

• Direct VTT REST API Bridge: Inside the Audio Scribe, you can now enter your Foundry VTT or Roll20 API URL and "Blast" your session journals directly into your live server.
• UI Stabilization: I’ve implemented "Component Airlocking." The bugs where microphones or buttons would "ghost" onto other pages have been completely eliminated.
• Performance: We’ve hit #3 on the global AI charts this month thanks to you guys! I’ve optimized the backend to handle the 4,000+ generations we've clocked so far.

Give the VTT blast a spin in your next session and let me know how the handshake feels!

Update: Real-Time Rules Lawyer is now Agent-Powered (v4.0)

I just pushed a major backend update to DM Co-Pilot. The Rules Lawyer tool now runs on a two-agent "Researcher/Auditor" loop. One agent is restricted to only pulling raw 5e SRD mechanics, while a second high-reasoning agent audits those facts against your specific table dispute.

It effectively eliminates the "creative guessing" AI usually does, providing a legalistic ruling DMs can actually rely on mid-session.

[Update v4.1] The Fate-Threader Combat Simulator is LIVE (and we hit #1!)

First of all, I am completely blown away. Because of the insane amount of stress-testing and feedback from this specific thread, DM Co-Pilot just hit #1 on the global Viberank charts for AI Apps! I literally could not have done this without you guys breaking my code all weekend.

To celebrate, I spent the entire night building the most requested feature: The Fate-Threader (v4.1).

If you are ever worried about accidentally TPK'ing your party with a homebrew boss, you can now input your party size, average HP, and the monster's expected Damage Per Round. The app instantly runs 1,000 parallel Monte Carlo simulations in the background and spits out a TPK Probability % and a Survival Rating (Safe, Dangerous, or TPK Likely).

I just finished doing some midnight code surgery to make sure it runs with zero latency directly in your browser. Give it a shot before your next boss fight: dm-copilot-cloud.onrender.com

I'm officially signing off and crashing for the night. Keep the feedback coming, and I'll check the server logs in the morning!

[Teaser] What's coming in v5.0...You guys helped me push the combat simulator to the limit, so I want to share what I'm building next.

1. The Butterfly Effect Graph: A visual, interactive map of your campaign that dynamically changes colors and links when your players do something chaotic.
2. Ghost NPCs: A feature where you can click a button, speak into your mic, and the AI will respond out loud in character as your NPC.Time to start coding!

We hit #1! + v5.0 is LIVE with the "Butterfly Effect" Map (And a tease for what's next...)

Hey everyone, first off—thank you. Your feedback on the Fate-Threader combat math was invaluable, and thanks to you guys stress-testing the app, DM Co-Pilot actually hit the #1 spot on the Viberank AI charts this week!

But we aren't slowing down. I just pushed v5.0 live, and it introduces a massive new feature: The Predictive Heatmap.

I wanted the AI to actually understand the consequences of your world. Now, you can type in a chaotic player action (e.g., "The rogue burned down the Sleeping Giant tavern"), and the engine will calculate the ripple effects and generate a visual, interactive web of nodes. It shows you exactly which factions just turned hostile, friendly, or neutral based on that one action. It's the Butterfly Effect, mapped in real-time.

What's Next (The Tease): Ghost NPCsI am currently prototyping a sub-second Voice-to-Voice agent. Soon, you'll be able to click a button, let your players speak directly into the microphone to interrogate a goblin or barter with a merchant, and the AI will respond out loud, in character.

The code surgery for the voice engine starts today. Let me know what you think of the Heatmap in the meantime!

[Update v5.0] The 'Onyx' Voice Engine is Live!

Hey everyone, thanks for the incredible feedback on the Fate-Threader combat math. While that was building, I was performing some 'code surgery' on our NPC interactions.

I’ve officially replaced the standard gTTS engine with a premium OpenAI Onyx Voice Engine. If you’ve been using the tool, you know the old voice was a bit... robotic. Now, the NPCs have a deep, gravelly, world-weary tone that actually fits a D&D session.

What's new:

• Sub-Second Latency: Talk to the mic, and the NPC answers almost instantly.
• Cinematic Tone: Specifically tuned the 'Onyx' engine for gritty fantasy roles.
• Secure Vaulting: Your API keys are now handled via secure environment variables to ensure zero downtime.

Give the 'Ghost NPC' tool a spin and let me know if it's immersive enough for your tables!

[Update v5.0] We hit #1! + The Voice-to-Voice "Ghost NPC" Engine is LIVE

Hey everyone, first off—a massive thank you. Because of your relentless stress-testing and feedback over the last few weeks, DM Co-Pilot officially hit the #1 spot on the global Viberank charts for AI Apps this week!

To celebrate, I just pushed the v5.0 Masterwork Update live, and it includes the feature I am most excited about:

Ghost NPCs (Voice-to-Voice Agent): You can now speak directly into your microphone to interrogate a goblin or barter with a merchant, and the AI will respond out loud, in character, with a cinematic "Onyx" voice.

How to use it (The "BYOK" Model): To keep the servers from melting, the logic engine requires you to drop your own (free) Groq API key into the sidebar. However, as a thank you to this forum, I am bankrolling the premium OpenAI Onyx voice. Your first 5 voice interactions per session are completely on the house!

The Predictive Heatmap: I also added a Butterfly Effect engine. Type in a chaotic player action, and the app will generate an interactive web showing exactly which factions just turned hostile or friendly.

Thank you for being the best QA team an indie dev could ask for. Give the voice engine a spin and let me know how it feels at the table!Live App: Streamlit
