Vocast - Article to Podcast Converter

Convert articles and reading lists into audio podcasts using local text-to-speech, so users can listen while walking or commuting. Self-hosted option avoids subscription costs. Target users are readers who want hands-free content consumption.

Text-to-audio conversion is genuinely crowded right now — Pocket, Instapaper, and even Apple's built-in Listen to Page feature already serve the commuter-reader use case, and ElevenLabs has made high-quality TTS a commodity API call. The self-hosted angle is the only real differentiator, appealing to privacy-conscious or cost-sensitive power users, but that same niche-within-a-niche constraint explains why the revenue ceiling sits at $3k/month — the audience willing to self-host is technically capable enough to stitch together an open-source equivalent in a weekend. The unit economics only work if there's a managed hosted tier with a clean per-seat or usage-based price, since pure self-hosted tools historically struggle to convert users into paying customers. The most likely failure mode is that TTS quality shipped directly inside browsers and mobile OS continues improving, quietly eliminating the reason to run a separate tool at all.
