Epicenter GTM brain

Epicenter builds open-source local-first productivity apps that share portable user-owned memory for individuals and developers.

category

Local-first AI productivity and memory

market profile

  • text: Notes, transcripts and chat histories are fragmented across apps, making shared context and portability difficult.
  • text: Whispering competes in voice transcription while Epicenter's broader ambition is a shared local-first data layer across applications.

personas

  • title: Developer and local-first app builder
    pains:
    • App-specific data silos make user context hard to reuse.
    • Wants inspectable storage, self-hosting and freedom to select models and tools.
  • title: Knowledge worker using AI and transcription
    pains:
    • Moving recordings and notes between transcription, editing and AI tools requires copying or exports.
    • Cloud subscriptions and proprietary formats make accumulated work harder to own and move.
  • title: Privacy-conscious researcher or creator
    pains:
    • Sensitive notes or transcripts may be sent to a cloud provider without an acceptable trust model.
    • Wants a choice of local models and control over files after changing applications.

icp

  • text: Individual developers, technical knowledge workers and creators who already use Markdown, Obsidian, Git or local models.
  • text: Small teams and independent builders valuing open-source, self-hosted tools and portable transcripts over proprietary cloud workflows.

message pillars

  • text: Keep a portable shared memory under user control.
  • text: Bring existing tools and models into the workflow.
  • text: Inspect and adapt the software.

objections

  • objection: I already use Obsidian for notes.
    response: Epicenter describes a shared storage layer across apps; test whether transcription and other tools improve the existing Obsidian workflow.
  • objection: Does local-first mean hosted sync is end-to-end encrypted?
    response: The site says Epicenter Cloud's sync server can read plaintext; self-hosting changes that trust boundary. Review the deployment before storing sensitive data.
  • objection: Will I have to pay for a model provider?
    response: Whispering supports local and cloud models and users choose their own model or API key; provider charges depend on that choice.

    title: Founder
    role: Founder
    bio: At 18, I taught myself to code while studying ethics, politics, and economics at Yale. Since then, I’ve averaged ~10k commits/year and worked at three YC startups. I wrote my 65-page senior thesis on open-source governance and digital platforms. I care deeply about data ownership, open-source, and interdisciplinary thinking. https://github.com/braden-w/ I build tools to help automate the boring parts of my writing. Hopefully, something good comes from it!
