omnicaptions-LaiCut

omnicaptions-LaiCut is a skill for Claude Code from lattifai/omni-captions-skills. It costs 49 tokens per session (1,559 once invoked), scanned A, original, MIT.

A service for matching written transcripts or captions precisely to the speech in an audio or video file. This process is called forced alignment and corrects subtitle timing.

In plain words
What is it for?
Use it to align an existing transcript, repair downloaded captions, or improve timestamps after automatic transcription. It requires a LattifAI API key.
Why use it?
It fixes captions that start too early, too late, or drift out of sync with the speaker.

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.

Security

Grade A, and why

omnicaptions-LaiCut 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 12d 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.

LaiCut

LattifAI's audio-text processing toolkit. Currently supports forced alignment, with translate and speaker diarization coming soon.

Requires LattifAI API Key - Get from https://lattifai.com/dashboard/api-keys

When to Use

  • Accurate/precise timing needed - When user requests accurate timestamps or precise alignment
  • Sync misaligned captions - Fix timing drift in downloaded captions
  • Align manual transcripts - Match text to speech precisely
  • Post-transcription alignment - Improve timing from auto-generated captions
  • Multi-format support - SRT, VTT, ASS, LRC, TXT, MD

When NOT to Use

  • Need full transcription (use /omnicaptions:transcribe)
  • No existing caption/transcript (nothing to align)
  • Very short clips (<5 seconds)

Setup

pip install "omni-captions-skills[laicut]" --extra-index-url https://lattifai.github.io/pypi/simple/

API Key

Priority: LATTIFAI_API_KEY env → .env file → ~/.config/omnicaptions/config.json

If not set, ask user: Please enter your LattifAI API key (get from https://lattifai.com/dashboard/api-keys):

Then run with -k <key>. Key will be saved to config file automatically.

CLI Usage

# Basic alignment (default: JSON with word-level timing, RECOMMENDED)
omnicaptions LaiCut audio.mp3 caption.srt
# → caption_LaiCut.json

# Then convert to desired format (preserves word timing in JSON for future use)
omnicaptions convert caption_LaiCut.json -o caption_LaiCut.srt

# Smart sentence segmentation (for word-level captions like YouTube VTT)
omnicaptions LaiCut video.mp4 caption.vtt --split-sentence
Option Description
-o, --output Output file (default: <caption>_LaiCut.json)
-f, --format Output format (default: json)
-k, --api-key LattifAI API key
--split-sentence AI-powered semantic sentence segmentation
-v, --verbose Show progress

JSON output preserves word-level timing for downstream tasks:

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
