For genealogists

Built on the Genealogical Proof Standard

For you who research on commission, write local history or lead a family history society – and want to defend every conclusion.

Proof standard

What the source says and what you conclude are two things

Mimir keeps each source's assertions apart from your conclusion. Conflicting information stands side by side until you have reasoned it out – and the reasoning becomes part of the tree.

Church-book excerpt for Erik's baptism in 1874

Six statuses, never embellished

The status is derived from the sources and your evaluation – never stored on its own, so it can never be left wrong.

Unsourced
No source supports the fact yet.
Sourced
At least one source supports it.
Confirmed
Two independent sources support it. Family tradition counts only once.
Proven
You have concluded, with a proof argument.
Disputed
A source says otherwise.
Disproven
You have concluded the fact is wrong.

The tools

Assertion and conclusion

Every assertion gets its information and evidence type – primary or secondary, direct or indirect.

Citation templates per kind of source

Parish registers, censuses, probate, mortgage registers, court records, emigration records, local histories and newspapers – each with the fields it needs.

Research log and tasks

Where you looked, what you did not find, and what comes next – per person and for the tree.

Proof argument

Write the reasoning behind a conclusion, with the sources it rests on – while the evidence is still being weighed, or once you have concluded.

Oral sources weighed rightly

An oral account is weighed by how the informant knows it – were they there, or did they hear it from someone?

No lock-in

The whole tree out at any time: GEDCOM 5.5.1 or 7, GEDZIP with the photos, or Mimir's documented lossless JSON format.

Privacy you can stand behind

Living persons are filtered on the server, in exports and search too. Data is stored in Norway, and nothing is shared with third parties.
