Go from blank sheet to system architecture.
Phosphor helps electronics teams work from requirements, datasheets, previous projects, and constraints toward concrete architecture decisions and tradeoffs.
Move faster from design to working board.
Phosphor is an AI agent that understands your design files, datasheets, and parts, helping you make decisions faster, catch issues before the next board spin, and bring up boards with less guesswork.
From block diagram to working board
Pick parts without getting lost in the weeds.
Phosphor searches distributor data, reads datasheets, and ranks candidate parts against electrical requirements, package fit, availability, pricing, lifecycle, and board constraints.
Catch issues before the spin.
Phosphor cross-checks the design the way an EE would: tracing signals through the schematic and PCB, comparing them to datasheets and interface standards, and surfacing places where the implementation deserves a closer look.
Escape integration hell.
After the board comes back, Phosphor helps keep bring-up moving: compare expected behavior against measurements, control bench instruments for debugging, write project documentation, and help AI coding agents write firmware that matches the actual board.
See it handle real engineering work.
Real conversations from the Phosphor desktop app, showing work across part selection, BOM checks, interface review, bring-up planning, documentation, and bench debugging.
01 - DesignSelect a boost converterWorks through a 3.3 V, 300 mA boost search for a near-dead alkaline cell, checking DigiKey stock, package area, startup voltage, and current-limit evidence before recommending parts.
02 - DesignReview PCIe interfaceFollows a PCIe connection through the schematic and PCB, checks routing and stackup assumptions, and separates verified design risks from baseboard-dependent unknowns.
03 - DocumentationCreate board documentationReads the schematic and PCB files, then creates documentation visuals and component notes that explain the board architecture.
04 - Bring-upPlan power rail bring-upTraces the power tree into a bring-up checklist covering rails, enables, resets, test points, and processor startup conditions.
05 - Bring-upCapture scope waveformFinds a connected oscilloscope, captures a measurement, and summarizes the result for debugging.
06 - ReorderReview BOM for reorderWalks a production BOM line by line, checking distributor availability, current pricing, lifecycle status, and sourcing risks before reorder.

Results you can trust.
Phosphor's citation system requires the model to cite source data for every claim. A verification step checks that each citation is accurate. You see page numbers, specs, and references alongside every answer, so you can confirm for yourself. A built-in knowledge library grounds the model in best practices for repeatable, reliable results.
What's the max output current for the LM3940?
PhosphorThe LM3940 can deliver up to 1A of output current[1] with a dropout voltage of typically 0.5V at full load[2].

You control your data.
Phosphor runs on your desktop. Your files are never uploaded to our servers. Design data sent to the LLM provider is not stored or used for training. Enterprise teams can bring their own API keys, route through their own LLM gateway, and self-host the document processing pipeline.
