Rhumb
A route between two sources that can be sailed without rewriting the coast.
A living atlas for research
Meridian draws your sources as routes, harbors, and weather. The plate is honest about disagreement. The signature on the cartouche stays yours.
Rhumb
A route between two sources that can be sailed without rewriting the coast.
Harbor
A port of agreement. Named. Dated. Allowed to silt.
Sounding
Depth of certainty. Shallow numbers are not a failure; they are the work.
Weather
What changed since the last plate. Fog is drawn, not deleted.
Instruments on the plate
02°
A rhumb is a constant bearing between two fragments. Meridian will not invent a coastline to make the line prettier. If the sources disagree, the plate shows two coasts.
14°
A harbor is where a team is willing to land. It needs a name, a date, and a keeper. Consensus is a port, not a fog bank.
28°
Every claim carries a depth. Twelve fathoms of evidence is drawn differently from two. The lead line stays on the table.
How a plate is drawn
I
Notes, transcripts, PDFs, half-true Slack threads. The plate accepts a mess. It will not pretend the mess is a coastline.
II
You mark which sources you trust enough to sail by. Meridian plots rhumbs between them and leaves the rest as fog.
III
Where the team can land, you write a harbor: a decision, a date, a keeper. Unsigned ports do not appear on the issued plate.
IV
The title block carries a name. That is the whole product. A chart without a helm is a decoration.
The bench
Meridian is not a dashboard pretending to be a map. The work still looks like a chart: dividers for distance, a lead for depth, a cartouche for the name you are willing to sign. The software holds the plate still while you decide.
If a tool cannot be named in the language of the bench, it does not ship.
What the plate will not do
Meridian will not smooth two contradictory sources into one pretty shoreline. You pick a bearing, or the plate shows both.
If a source moved, the weather glass records it. Confidence is drawn, not implied by a green badge.
The cartouche needs a human name. The model does not issue plates. It sharpens pencils.
Who lands here
A desk that plots claims as rhumbs and refuses a single coast when two desks disagree.
A plate for a paper that is still underway. Soundings instead of a fake “done.”
Harbors with keepers. Briefs that remember who signed, and what the weather was.
Passage
Coastal
$0/mo
One plate, one keeper. Enough to learn the grammar.
Offshore
$48/mo
A desk for a research crew. Harbors can be named.
Blue water
Letter
A chartroom. Several crews, one atlas, a keeper of the log.
Notices to mariners
No. It holds the plate. You take bearings, name harbors, and sign the cartouche. The model is a pencil.
It will not. Disagreement is drawn as two coasts, or as fog, until a keeper names a harbor.
No. There is no ops wall, no night desk, no glowing board. The product is a chart you can issue.
Offshore and Blue water issue a dated PDF with the cartouche, scale, and soundings. Coastal keeps the plate on the table.
In this template they do not. They are furniture. Submit the form and you will be told so, then pointed home.
