The problem
Why old diaries are so hard to read
A family diary is one of the most personal documents you can inherit – and one of the hardest to use. Unlike a letter, a diary spans years or decades. The handwriting changes as the writer ages, eyesight worsens, or writing tools change. Entries from 1890 may be in careful copperplate, while entries from 1920 use a looser, faster hand that barely resembles the same person's writing. Add personal abbreviations, cramped pages, and faded pencil or ink, and even a fluent reader of old scripts can struggle.
Handwriting that changes over years – the same diary can contain multiple distinct styles
Personal abbreviations for recurring names, places, and daily activities
Cramped, space-saving writing – especially in wartime diaries where paper was scarce
Faded pencil, iron gall ink damage, and bleed-through on thin paper after 100+ years
Private shorthand that only the writer understood – no standard reference exists
The solution
AI that adapts to changing handwriting
Transkribus uses handwritten text recognition (HTR) – AI trained on millions of historical handwriting samples. Unlike letter-by-letter decipherment, the AI reads words in context: it predicts what comes next based on surrounding text, so it handles abbreviations and ambiguous letterforms far better than manual reading. Upload a photo or scan, select a model, and get readable text back in seconds.
Context-based recognition – the AI predicts words from surrounding text, not letter by letter
Adapts to changing handwriting styles within the same diary

Handwriting changes
When the handwriting changes across decades
A diary started in 1890 might begin in careful copperplate and shift to a looser, faster hand by 1920. Age, injury, arthritis, or simply changing conventions affect how people write. A writer who learned formal script in school may adopt a more personal style over decades – and wartime entries, written under stress or by candlelight, often look different again. The AI handles this because it recognises patterns in context, not by matching individual letters to a fixed alphabet.
Early entries in formal, taught script – later entries in a personal, evolved hand
Age-related changes: tremor, larger letterforms, simplified connections
Wartime entries often written in haste, pencil, or poor lighting conditions
Different writing implements across decades – steel nib, fountain pen, ballpoint, pencil
The AI adapts to each style without needing you to switch models manually
Abbreviations
Abbreviations, shorthand, and private notation
Diarists abbreviate far more than letter-writers. A letter needs to be understood by someone else, but a diary is written for the author alone. Recurring names, places, and activities get shortened to initials or personal codes. 'M.' might mean Mother, a neighbour, or a place – and the meaning may shift over years. The AI has a genuine advantage here: it uses the words around an abbreviation to predict what it means, rather than guessing letter by letter.
Personal codes for family members, neighbours, and recurring places
Abbreviations for daily routines – weather, meals, visitors, work
Context-based prediction resolves ambiguous shorthand better than manual reading
Recurring patterns become more reliable across multiple pages of the same diary
Confidence scores flag uncertain readings so you can check against context clues
Multi-page documents
200 pages? Here's how to approach it
A diary is not a single page – it can be 100, 200, or more. The demo widget above is perfect for trying a few pages instantly, free and without signup. For an entire diary, a free account is the practical approach: you get 50 credits every month (enough for about 50 pages), and batch upload lets you process all pages at once instead of one by one. No credit card required to start.
