Privacy

Nobody reads your prompts. Not even us.

On a cloud service, your prompts, your voice and your unreleased work are processed on servers you do not control, under rules you did not write. Foundry runs on your own PC, so none of it reaches us.

Under the hood

How Foundry runs on your PC.

Foundry is not a front end for a third-party service. The models are reworked by us and run through our own inference stack, on your machine. This is how a line of text becomes a performance.

  2. Plans the deliveryacoustic tokens, 12 times a second
  3. Holds the speakeridentity conditioning
  4. Adds the feelingstyle and emotion conditioning
  5. Renders the soundwaveform decode
Speech v4
A substantially reworked Qwen3-TTS foundation: stable long-form speech, fine expressive control, one consistent speaker.
Foundry Music v4
Built on a modified ACE-Step 1.5 foundation, with spectral-flux stabilization inside the generation itself. Six models for 6 GB to 12 GB+ cards.
Foundry ASR v4
Transcription with word-level timing and speaker separation. It drives Dubbing and Dictation.
Inference stack
All of it runs locally through our own C++ stack built around GGML and ONNX.

Frequently Asked Questions

Does Demodokos Foundry work offline?

Yes. All AI generation, voice cloning and audio processing happen locally on your GPU. Your prompts, scripts, voice samples and generated audio are not uploaded to a cloud service. An internet connection is still required for login and license verification. Foundry may sign you out if it cannot reach the authentication server for an extended period.

Does Demodokos Foundry upload my audio files to the cloud?

No. Your audio files, voice samples, prompts, scripts, project data and generated content stay on your computer. Foundry does not upload creative content to a cloud AI service for generation or processing.

What GPU do I need to run Demodokos Foundry?

An NVIDIA GPU with at least 4 GB of VRAM can run selected Speech models at reduced quality. 6 GB is a more practical starting point, while 12 GB or more is recommended for the best overall Music and Speech performance. AMD GPUs with at least 8 GB of VRAM can run both Music and Speech through Vulkan, although AMD support remains experimental. NVIDIA with CUDA is recommended.

I have an AMD GPU. Will that work?

Yes. AMD GPUs with at least 8 GB of VRAM can run both Music and Speech through Vulkan. AMD support remains experimental and may be less consistent than NVIDIA/CUDA, which provides the most mature Foundry experience.

Does Demodokos Foundry run on macOS or Linux?

Foundry is currently available for 64-bit Windows 10 and Windows 11. Native macOS and Linux versions are not currently available.

How much does Demodokos Foundry cost?

The Creator plan is $15.00/month and the Professional plan is $49.00/month. Discounted annual billing is also available. Both plans include unlimited local AI music and voice generation without per-generation credits; plan limits apply to project size, duration and advanced features. A free 7-day trial is included.

Is there a free trial?

Yes. Demodokos Foundry offers a 7-day free trial with the full capabilities of your selected license. It is processed through PayPal with a $0 authorization, and you are not charged unless you keep the subscription after the trial ends. Cancel any time before the trial expires.

Can I cancel my subscription anytime?

Yes, any time, under Billing > Cancel. Cancelling stops your next renewal and takes effect at the end of your current billing period - the current month for monthly plans or the current year for annual plans. You keep full access until then. Payments already made are not refunded, and there are no cancellation fees. During a free trial, you can cancel any time with no charge.

Can I clone my own voice with Demodokos Foundry?

Yes. Import a short recording of your voice (or another voice you are authorized to use) and Foundry creates the cloned voice locally on your machine. Cloned voices can speak all 10 languages and use more than 40 emotions and speaking styles, each with five intensity levels, without per-character or per-generation charges.

What languages does Demodokos Foundry support?

Demodokos Foundry supports music generation and lyrics in 50 languages, and speech and voice generation in 10 languages. The Creative AI agent is optimized for English conversation. Larger Creative AI models available on higher-VRAM systems understand additional languages and provide stronger multilingual lyric writing, text analysis and narration support.

Does Demodokos Foundry use open-source or proprietary AI models?

Demodokos Foundry uses proprietary AI systems and adapted models developed from open-source foundations. Demodokos extensively modifies, extends and further adapts those foundations before integrating them into its proprietary music, speech and audio-production architecture.

The Music v4 engine builds on a modified ACE-Step 1.5 foundation, with spectral-flux-guided stabilization integrated directly into the generation process. Speech v4 advances Qwen3-TTS through further adaptation and extensive architectural changes, while Creative AI uses constrained Qwen3 language models within a custom agentic pipeline. Demodokos has also re-engineered Metas AudioSeal technology into Tonotope, a lightweight AI-origin marking system embedded directly into generated audio while remaining inaudible.

All AI inference runs locally through a custom C++ inference stack built around GGML and ONNX.

Is Demodokos Foundry just a wrapper around open-source AI models?

No. A wrapper typically places a new interface over an existing model while leaving the underlying technology and workflow largely unchanged. Foundry goes much further.

Demodokos modifies and extends the models themselves, then builds proprietary generation, voice-consistency, orchestration and audio-processing systems around them. Music v4 and Speech v4 include changes that directly affect musical stability, speaker identity, expression and long-form consistency.

The difference is especially visible in the rich Speech Editor. It combines a familiar document-writing experience with tools built specifically for spoken production: visual speaker and delivery cues, background music and sound inserts, overlapping dialogue, natural crosstalk, sample-accurate timing and visually adjustable DSP effects. Every sentence can be previewed, edited or regenerated in context, with individual control over pace, pitch, volume and delivery.

Foundry´s agentic pipelines can process entire books, split them into chapters, summarize and analyze their content, inspect images and OCR text, identify speakers, create voices from AI-generated character descriptions and prepare narration. A separate narration pipeline can adapt text, choose the right speaker and select fitting emotions line by line.

Projects can then move into music generation, stem separation, section repair, timeline arrangement, mixing and final export. Foundry is not a front end for third-party models; it is an integrated local audio-production environment built to take long-form text from document to finished sound.

How is Demodokos Foundry different from ElevenLabs?

ElevenLabs is a cloud platform built around monthly usage credits. Demodokos Foundry is a local Windows audio-production environment: generation runs on your own GPU, your scripts, voices and audio stay on your machine, and output is not metered by characters or per-generation credits.

Foundry is also designed around complete productions rather than isolated generations. Its rich Speech Editor lets you write in a familiar document interface, assign speakers, direct emotion and delivery line by line, insert music and sound, build overlapping dialogue and crosstalk, regenerate any sentence in context, and adjust pace, pitch, volume, timing and DSP without leaving the document. Agentic workflows can prepare whole books by segmenting chapters, analyzing text and images, identifying speakers, designing voices and directing narration.

Music generation, stem separation, section repair, timeline mixing and automation are built into the same desktop application. The key difference is a private, integrated local studio instead of a cloud service whose usage is measured in credits.

Is Demodokos Foundry safe for business and GDPR compliant?

Yes. Demodokos Foundry is designed to support GDPR-compliant workflows. All AI generation, voice cloning and audio processing run on your own hardware, so business content, client audio, proprietary voice recordings, internal scripts and confidential narration stay on your premises instead of being sent to a cloud AI provider. No cloud AI provider receives or retains your creative content. This gives your organization direct control and data sovereignty over the generation workflow, making Foundry especially well suited for businesses, legal teams, healthcare, media agencies and other privacy-sensitive work.

Is Demodokos Foundry AI Act compliant?

Yes. Demodokos Foundry is designed to meet the applicable transparency requirements of the EU AI Act. Generated audio is identified as AI-generated in its metadata and carries Tonotope, Demodokos´ robust, inaudible AI-origin watermark.
