An audio-timing workflow that finds timestamps for individual words in a recording. Word-level timing shows when each spoken or sung word starts and ends.

Use it to align lyrics, set precise caption boundaries, and prepare timing data before burning captions into a video.

It makes captions and video cuts line up with the actual speech or lyrics instead of relying on rough sentence timings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.01192
Opus 5.5	$0.00014	$0.00477
Sonnet 5.5	$0.00007	$0.00238
Haiku 4.5	$0.00003	$0.00119

Measured 10d ago against content hash 21f20904a2b1, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

whisperx scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prerequisites

Install and load these skills before generating (skip if already in context via @pruna):

Skill	Description	Install
`generation-diversity`	Use when writing any generative prompt — ritual seed, explicit structure, scenario axes, and quality gates before paid API calls.	`npx skills add PrunaAI/pruna-skills@generation-diversity -y`
`pruna-api`	Use before any Pruna or Replicate HTTP call — credentials, upload/poll/download, parallel batches, and agent safety.	`npx skills add PrunaAI/pruna-skills@pruna-api -y`

Or install the full suite once: npx skills add PrunaAI/pruna-skills@pruna -y

Follow each skill's Before generating / craft sections — do not restate guide content here.

Agent habit

In the first reply, name `whisperx` in backticks, confirm REPLICATE_API_TOKEN (or stop with signup links from pruna-api), then ask for required inputs. Open intake → generation-diversity clarification intake before the first POST. Redirect when When NOT to use fits better.

When NOT to use

Use a different skill instead:

Skill	Description	Install
`music-2.5`	Use when someone wants an original AI song with vocals — sung lyrics, a style prompt track, or source audio for a music video.	`npx skills add PrunaAI/[email protected] -y`
`gemini-3.1-flash-tts`	Use when someone needs spoken narration or voiceover — explainer tracks, documentary lines, or voice to pair with generated video.	`npx skills add PrunaAI/[email protected] -y`
`video-editing`	Use when assembling or polishing already-rendered clips with ffmpeg — concat, crossfades, burned captions and subtitles, text/logo overlays, before/after sliders, background music beds, platform export — or when composing a multi-layer HTML combination video with Hyperframes. Not for AI video generation, prompt craft, or model-based video edits.	`npx skills add PrunaAI/pruna-skills@video-editing -y`
