Questions, answered.
What Aludel needs, where your data goes, what Pro costs, and how to get unstuck.
General
What is Aludel?
A macOS app that turns text (files, URLs, or pasted text) into a two-voice podcast, through a six-stage pipeline: ingest → normalize → script → voice → mix → export.
How is it different from NotebookLM?
NotebookLM helps you understand sources; Aludel helps you publish an episode. You edit the script before synthesis, choose voices and models, and can run entirely offline. See the full comparison.
Install & requirements
What does it run on?
macOS 12 or later on Apple Silicon (M-series). About 26 MB. The current beta build is Apple Silicon only.
Do I need an account?
No. Aludel works without any registration.
Do I need internet?
Once it's set up, no — the local providers (Ollama + Piper) run the whole pipeline offline. You do need a connection the first time, to download the Ollama model and the Piper voices, and whenever you choose a cloud provider (OpenAI, Anthropic, OpenRouter, ElevenLabs).
Content, script & languages
What can I import?
.txt, .md, .html and .pdf files, a URL, or pasted text. Long books are split into chapters automatically.
Can I combine several sources in one episode?
Not yet — Aludel works on one source at a time. Multi-source synthesis is NotebookLM's territory.
Can I edit the script before the audio?
Yes — it's the core of the product. Read and fix the full two-voice dialogue before anything is synthesized. It's the cheapest place to control quality.
Can the podcast be in a different language than the source?
Yes. Output language is decoupled from the input: give it English, get Italian (or one of 9 languages), written directly in the target language in one pass.
Models & API keys
Which providers can I use?
Local, free and offline: Ollama (LLM) and Piper (voices). Cloud (Pro), with your own API keys: OpenAI, Anthropic and OpenRouter for text; ElevenLabs, OpenAI TTS and OpenRouter TTS (e.g. Kokoro) for voices.
What do cloud providers cost?
You pay actual usage directly to the provider with your own keys. Aludel adds no fee or markup, and shows a cost estimate before cloud synthesis.
Where are my API keys stored?
Locally, in ~/.config/podcastgen/config.json. They never pass through any Aludel server — only the provider you use. They're currently kept in plain text there (protected by your OS user account); moving them to the macOS Keychain is planned.
Privacy
Does Aludel collect telemetry?
No. There are no analytics, trackers, or crash reporters, and no servers of ours. Aludel collects nothing and doesn't phone home for normal use.
When does Aludel connect to the internet on its own?
Only in explicit cases: cloud providers you choose; Pro license activation (key + a device ID to Lemon Squeezy, the payments provider, with a background revalidation ~every 30 days — Pro only); on-demand downloads of a Piper voice, an Ollama model, or a URL you import; and a once-a-day update check (fetches only a version number from aludel.matteobalocco.it, off-switchable in Settings). Nothing else leaves the app.
Are my documents used to train models?
No.
Export
What formats can I export?
MP3 (128 kbps by default), plus WAV and OGG on Pro, with ID3 metadata.
Is the file mine?
Completely. No watermark, no restriction. The audio is mixed with natural pauses and normalized to a consistent −16 LUFS, ready to publish.
Pricing & beta
What does it cost?
The full local pipeline is free, forever. Aludel Pro is €XX free while in beta (€XX once at launch) — a perpetual license, no subscription. See Free & Pro.
How does the beta work?
During the beta, purchasing is off. Download the free version and request a free, time-limited (renewable) beta key to try the Pro features. It's free during the beta; the €XX price takes effect at launch, and beta testers get a launch discount.
How do I report bugs or send feedback?
Email aludel@matteobalocco.it, or use 'Send feedback or report a bug' on the app's Settings → License page. Every report helps shape the launch.
Troubleshooting
I picked Ollama but it says it isn't running.
Make sure the Ollama app is running (it lives in the background), then press Re-check. On a non-standard host/port, use the custom host field.
Are Piper voices available in my language?
The Piper catalog is multilingual; pick voices filtered by your output language. For the best quality, the cloud voices (Pro) are stronger.
Still curious? Just try it.
