Fuse design and engineering
A reference library for fuse design, built for engineers.
Browse and search real fuse designs, specs and patterns in one place. Claude analyses and tags every uploaded design and datasheet, writes a structured summary, and powers natural-language search.
Private beta. Access is by invitation.

01 How it works
One library for the designs your team keeps reusing.
Three steps from upload to a reusable reference.
-
STEP 01
Browse and search
Find real fuse designs, specs and patterns in one place. Search by what you need, in plain language.
-
STEP 02
Upload and let Claude read
Add designs and datasheets. Claude analyses each upload and tags it so it can be found later.
-
STEP 03
Get structured summaries
Every item gets a structured summary of its specs and patterns, ready to compare and reuse.
02 Features
Find, compare and reuse fuse designs.
Wweer keeps designs, datasheets and drawings in one searchable library, and reads each upload so you can find it by what it does.
-
Search
Search in plain language
Type the condition you need, the way you would ask a colleague. Examples:
- fast-acting 10 A fuses for a 24 V supply
- holders for 6.3 × 32 mm cartridges
- low-profile blade fuses with an indicator
-
Tagging
Claude tags every upload
Each design is tagged by fuse type, rating, package, standard and application, so filters and search work on the same fields.
-
Summaries
Structured spec summaries
Datasheets become a structured summary of ratings, dimensions, breaking capacity and time-current characteristics, ready to check against the source.
-
Compare
Side-by-side comparison
Put two or more fuses next to each other, row by row, with the same fields in the same order.
-
Team
A shared team library
Your team works from one reference instead of folders of files. Access is by invitation during the private beta.
-
Uploads
PDFs and drawings
Upload datasheets as PDF and drawings as files. Each upload is stored with the design it belongs to.
03 Who it is for
Engineers and designers who reuse fuse work.
For people who work on fuse designs and need to reuse what already exists.
- Design engineers check existing fuse layouts and patterns before starting a new one.
- Electrical engineers compare specs and datasheets without opening every file.
- Product teams keep one shared, searchable reference for fuse work.
04 How Claude is used
Claude reads, tags and summarises. Search runs on the results.
Wweer uses the Claude API to read uploads, write tags and summaries, and answer natural-language search. The product itself is built with Claude Code.
-
01 · UPLOAD
You add the file
A design, datasheet or drawing goes into the library.
-
02 · READ
Claude reads it
The Claude API reads the file and picks out the fields that matter.
-
03 · TAG AND SUMMARISE
Tags and a summary
Claude writes tags and a structured summary, stored with the upload they came from.
-
04 · SEARCH
Search runs on the results
A question in plain language is matched against those tags and summaries.
Wweer is an early-stage product, so the details will change as the beta grows.
-
API
Processed through the Claude API
Uploads are sent to Claude through the Claude API to produce tags and summaries.
-
Training
