Five files across four note types so every new Obsidian Base has something to display immediately when the vault is opened: - daily/2026-04-19.md — today's journal entry, covering the PKB setup work. Wikilinks to the permanent note, project brief, and reading note below. - notes/pkb-as-lens-substrate.md — the load-bearing design note capturing the PKB-as-substrate / Council-as-lens inversion that drove this whole extension. - projects/mql/brief.md and log.md — active project tracking the companion Markdown-Query-Language CLI (sibling repo). First log entry records the Go-over-Rust decision and v0.1 scope. - reading/audiopen-integration-research.md — marked done; captures the two-clouds distinction (AudioPen's processing cloud unavoidable; Obsidian Sync optional) and names Tailscale Funnel as the chosen webhook-exposure path. - inbox/2026-04-19-1900_test-ingestion.md — hand-authored fleeting note (source: manual, distinguishable from AudioPen drops) so /triage-inbox has something to exercise on before the real voice pipeline is running.

# AudioPen integration paths — self-hosted research
|
|
|
|
## Summary
|
|
|
|
AudioPen ships several output integrations: email, webhooks, direct-to-Obsidian (which routes through Obsidian's sync cloud), clipboard, and a few third-party automation platforms. The "direct to Obsidian" path is the one an earlier investigation surfaced, and it implicitly sends content through Obsidian Sync. For a self-hosted setup, that path is the wrong choice.
|
|
|
|
The cleaner architecture routes AudioPen's polished prose into user-controlled infrastructure via either a webhook (to a self-hosted receiver exposed via Tailscale Funnel) or email with IMAP pull on the desktop. Both fully avoid Obsidian's sync cloud.
|
|
|
|
The distinction worth holding: AudioPen's *processing* cloud (audio → polished prose) is unavoidable with AudioPen. The *storage/sync* cloud (Obsidian's paid service) is optional. This document is about the second.
|
|
|
|
## Highlights
|
|
|
|
- **Tailscale Funnel is the right tool for the webhook path.** Outbound-initiated; `*.ts.net` endpoint; no router ports opened; bypasses Authentik (which is gating Gitea's HTTPS in this setup).
|
|
- **Email+IMAP is the no-open-ports fallback.** Works if running a public-reachable receiver isn't feasible. Fully outbound.
|
|
- **Raw → normalised is a two-step pipeline.** AudioPen produces bare prose; a small bash wrapper wraps it in frontmatter and moves it from `inbox/raw/` to `inbox/`. Keeps the receiver stupid; all schema decisions live in one shell script.
|
|
|
|
## My notes
|
|
|
|
- AudioPen's payload shape varies slightly across versions. The receiver accepts multiple possible body keys (`body`, `output`, `summary`, `polished`) to avoid fragility; the raw payload is logged to stderr so you can inspect drift.
|
|
- If AudioPen's pricing or terms ever change, the documented escape hatch is whisper.cpp + a local polishing LLM + a phone-side Tasker/Shortcut. Out of scope for v1 but noted.
