A retired chemist turned a newsletter archive into an AI that writes book

A retired analytical chemist built an AI pipeline that turns French herbal newsletters into a research database and a full, evidence-ranked book chapter.

A retired analytical chemist sat on a personal collection of French-language phytotherapy newsletters and a dream of a book. In the program they built an AI agent that reads each letter, files the science into a relational database and writes chapters to their own strict standards. It is a story of a scientist's rigour meeting new tools, and of choosing real sources over easy volume.

Wetenschappelijke e-mail-extractie: phytotherapy knowledge pipeline

Before

They had a personal collection of phytotherapy newsletters in French, along with a plan for a book on herbal health. The material was rich but scattered across PDFs and languages. Turning it into something structured and trustworthy, with a chemist's standard for evidence, was a large manual job.

“This project turns that collection into a self-sustaining pipeline: source newsletter → structured extraction → relational database → publication-quality book chapter, with an AI agent doing the work at every step.”

In their own words

The turning point

Lesson 9 gave them the Memory, Brain and Skill framework, and Lesson 10 added the BRAIN framework of Base, Rules, Actions, Intelligence and Navigation. They wrote their own quality-standards document as the Rules layer and built two custom Claude Skills to read and extract each newsletter. Every new source now moves through the same four stages, ending in a written log that carries the work across sessions.

“Real data needs a live quality-control pass — direct API writes beat CSV re-import for anything you'll maintain.”

In their own words

After

Their pipeline reads a newsletter in French, Dutch or English, strips it to its science and feeds a five-table Airtable database of letters, conditions, remedies, sources and prescriptions. During the submission the agent scaled the database live, added peer-reviewed papers, fixed three data-integrity issues through the API and wrote a full chapter on Bacopa monnieri and cognitive ageing. They also tested it on two other named health writers, and it held up.

What it lets people do

The pipeline lets a researcher turn a pile of informal health newsletters into a searchable, linked body of knowledge. It writes chapters that rank evidence, use full Latin names, give dosage ranges rather than prescriptions, and treat newsletter claims as anecdote only.

What they learned

They learned that real data needs a live quality check, and that writing directly through the API beats re-importing files. Above all, they found that refusing to pad the count with promotional or invented content made the work stronger. In their words, working from real sources only was a feature, not a limitation.

“Working from real sources only turned out to be a feature, not a limitation.”

Description I'm a retired analytical chemist building a multilingual herbal-health knowledge base from a personal collection of French-language phytotherapy newsletters, as the foundation for a planned Amazon KDP book. This project turns that collection into a self-sustaining pipeline: source newsletter → structured extraction → relational database → publication-quality book chapter, with an AI agent doing the work at every step. What it does (achievements) Two custom Claude Skills read a newsletter PDF (French, Dutch, or English), strip it to its scientific content, and generate importable records for a five-table Airtable database (letters, conditions, remedies, sources, and prescriptions linking them). During this submission Claude used the pipeline to scale the database live and adding verified peer-reviewed papers with DOIs if available. Claude  also fixed three data-integrity issues directly through the Airtable API, and wrote one full chapter ("When Memory Falters: Bacopa monnieri and the Ayurvedic Approach to Cognitive Ageing") to a quality standard I'd defined in an earlier lesson: evidence hierarchy, full Latin nomenclature, dosage ranges rather than prescriptions, and a firm rule that newsletter content is treated as clinical anecdote, never as evidence on its own. Tools Claude (Cowork) as the orchestrating agent; two custom Claude Agent Skills (Scientific Content Extractor, Letter-to-Airtable-record); Airtable via its MCP connector as the relational "Brain"; a self-authored DNA quality-standards document as the Rules layer. Methodology Built on the Memory · Brain · Skill framework from Lesson 9, extended with the BRAIN framework (Base, Rules, Actions, Intelligence, Navigation) from Lesson 10. Each new source moves through the same four stages: extraction, structured storage, quality-standard-governed synthesis, and a written project log for continuity across sessions. Learnings Real data needs a live quality-control pass — direct API writes beat CSV re-import for anything you'll maintain. The pipeline generalizes across authors, not just Dr Willem's own writing (tested on two other named health writers). And the sharpest lesson was a constraint Claude set itself: given 15 new source documents, AI excluded 5 that were promotional or off-topic rather than pad the count, and declined to fabricate "in the style of" content to hit a target scale. Working from real sources only turned out to be a feature, not a limitation.

One source PDF, e.g. Gmail - Dormez comme un bébé !.pdf — the raw French newsletter, so you see what the agent actually reads. Its matching extraction in Dutch, e.g. 01-Astma-natuurlijke-remedies.docx. — the structured output from the same letter. For your convenience, an English translation of the above extraction: 01-Asthma-natural-remedies-EN.docx. It is kept structurally identical to the Dutch original so you can pair it with the French source PDF and see the extraction step directly AIM26-Skill-ScientificContentExtractor.docx — the actual skill definition (Role · Goal · Format · Tone · Rules) AIM26-Lesson10-Artefact03-DNA-Document.docx — the quality-standards reference that governs the book chapter's evidence hierarchy and disclaimers.
