The problem
The record you need is already in your files.
Serious research rarely fails for lack of documents. It fails because nothing connects the ones you already have.

disconnected tools in a typical workflow
Transcription is where the time goes
A single census page can take an hour to read by hand. Multiply that by hundreds of records and you've spent your research time on data entry - and the documents still aren't connected to anything.
Every record names people you're throwing away
A baptism names godparents. A marriage names witnesses. A census names the whole street. Those are the people who knew your family, and every tool you've used treats them as ink on a page.
The same person, scattered across your own files
One ancestor appears under five spellings in three languages across birth, marriage, and immigration records. Nothing unifies them, so the link between an 1847 baptism and an 1882 census stays invisible - and your archive never gets smarter as it grows.
No way to know what's missing
You can't see the gaps you haven't found yet. Existing tools show you the records you have, not the decade with no records in it or where to look next.
Twelve tools, zero integration
Scanned images in one place, transcriptions in another, a separate family tree app, a spreadsheet for notes. Nothing talks to anything, so every connection has to be made in your head.
The big platforms search their records, not yours
Hints compare your tree against someone else's database and someone else's tree, mistakes included. Nothing looks inward at the archive you built, which holds the only evidence you've verified yourself.
What it does
Built for the full research workflow.
Persistent person profiles
Every mention becomes one profile.
Across birth records, census pages, and immigration papers, the same person appears under different name spellings in different languages. KleioBase finds the likely matches and shows you the evidence; you decide which ones to merge.
Gap detection
See what you're missing.
KleioBase models your family's timeline and flags the periods with no records, then tells you where to look next, down to specific archive sources.
Old handwriting, 100+ languages
Latin, Hebrew, Cyrillic, Arabic, German Kurrent and more, in handwriting centuries old.
Family tree builder
Import existing GEDCOM files or build from scratch. Watch the tree grow as records are processed.
Research companion
Ask natural-language questions. Get sourced answers drawn from everything you've uploaded.
Separate workspaces
Keep your own family, each client, and one-off lookups in separate knowledge bases that never mix.
How it works
Upload. Extract. Connect.
Read the transcript
You have just uploaded a new record. Before you process it, two things are worth doing.
Most register pages hold more than one record. Drag a box around the entry you want, and only that one gets read. Everything outside the box is ignored.
Then add anything you already know. A place, a year, a family name. It does not need to be complete. It helps resolve handwriting that could be read more than one way.
DeepScan reads the page with a stronger model. It costs five credits instead of one, and on a hand like this one, it earns them. Then click process.
You get the transcription in the original language, a translation, and the details pulled out separately. Read them before you accept them. If you find anything that is wrong, you can correct it here.
Clicking confirm saves the record and the people in it. Matching runs separately in the background. KleioBase never merges anyone on its own.
When it finds someone who might already be in your tree, it shows you both side by side with the evidence, and you decide whether to accept or dismiss the match. You can also ask the Research Companion about the match and make it accept it for you.
That is just one record. Every other one works the same way.
01
Upload any document
Drag and drop photos or scans of records - birth certificates, census sheets, immigration papers, diaries, handwritten letters - as JPG, PNG or PDF. Faded and hard-to-read pages are fine.
02
AI reads and structures it
KleioBase transcribes the handwriting, translates the language, and extracts structured data: full names, dates, places, relationships, and record type.
03
Your archive connects
Confirming a record builds and updates person profiles. Likely matches across records are flagged for you to review. Gaps are surfaced with specific research suggestions.
