Yes, Decidel uses a Bring-Your-Own-Key (BYOK) model. You provide your own API key from providers like Groq (which has a generous free tier), OpenAI, or Anthropic. This means your data goes directly to your chosen provider — never through our servers.

Decidel supports Groq, OpenAI, Anthropic (Claude), Ollama (local models on your Mac), and on-device AI. Free users can use one provider at a time. Pro users can switch between all of them.

Your reading history, bookmarks, and settings never leave your device. When you use cloud AI providers (Groq, OpenAI, Anthropic), the HN content you summarize is sent to that provider's API — the same as if you used their service directly. For maximum privacy, use Ollama or on-device AI, which process everything locally.

Pro ($3.99/month or $19.99/year) unlocks unlimited AI summaries, unlimited Smart Mute concepts, multiple AI provider switching, offline reading bundles, advanced export to Notion and Obsidian, custom feed views, and priority feature requests.

Yes. Manage your subscription through the App Store. When you cancel, you keep Pro features until the end of your billing period, then revert to the free tier with all your data intact.

The free tier is the trial. Use 15 AI summaries per day and 3 Smart Mute concepts to see if Decidel fits your workflow. Upgrade to Pro only when you want more.
