AI Tool ConsultantLearn German with Claude
The daily method behind months of measured German progress, as skills Claude can run for you.
Four skills from a documented daily German journal: two-phase writing correction that tracks your error patterns, a learning coach built on what measurably worked (and what didn't), a speaking coach for voice recordings, and bilingual karaoke subtitles for videos of yourself speaking.
4 skills, each built from real work
German Writing Correction
Marks real errors with hints but no solutions, waits for your attempts, then gives honest feedback, the full error list, memory rules and a corrected version that keeps your style, tracking patterns in PROGRESS.md.
- From months of daily journaling at B2–C1
- Never credits an avoided construction
- Dictation tools aren't accepted as evidence (they silently fix errors)
German Learning Coach
Designs routines and sessions from a dated evidence log: yesterday's sentence spoken first, real work texts as material, pre-call briefings, pieces of five minutes or less, and honest progress measures.
- Every principle backed by a dated observation
- Pieces of five minutes or less with a fixed end
- Pre-call briefing that held up in a real interview
Language Speaking Coach
Transcribes recordings with word timestamps, re-checks doubtful words in isolation, and judges intelligibility first, pronunciation second and grammar last, with four fluency numbers and one sentence to repeat tomorrow.
- Intelligibility, then pronunciation, then grammar
- Four fluency numbers tracked over time
- Isolated re-checks catch the model 'repairing' your speech
Bilingual Karaoke Subtitles
Transcribes with word timestamps, re-checks doubtful words in isolation, aligns the highlight to the real voice, and renders with a resumable, rotation-safe script, plus notes comparing spoken and corrected text.
- Eight renderer versions distilled into one script
- Real word timings, not estimates
- Rotation-safe and resumable
Two minutes to install.

Which tools do the skills work with?
Claude.ai and Claude Desktop (upload a zip), Claude Code (plugin or folder), Codex (folder), and other agents that read the open SKILL.md format. A few skills include Python scripts; each skill page lists exactly what it needs.
How do I install them?
In Claude Code, add the private marketplace you're invited to after purchase and install the pack with one command. For Claude.ai and Claude Desktop, turn on code execution in Settings → Capabilities, then upload one zip per skill under Customize → Skills. For Codex, copy the skill folders into ~/.agents/skills/. Then ask normally; a skill switches on when your request matches it.
Do I get updates?
Yes. In Claude Code, turn on auto-update for the marketplace (/plugin → Marketplaces), or update a pack with claude plugin update <pack>@aitoolconsultant. Zip buyers can download the latest version from their purchase page.
Can I use them for my team or my clients?
Yes, for your own work and for client work you do. You can share a pack inside one team of up to five people at one company. Please don't resell or publish the files.
Do you see my data?
No. Skills are instructions and scripts that run inside your own AI tool. Nothing is sent to us.
