# BoardFix

> AI repair assistant and boardview viewer for component-level electronics repair. A technician opens the board file of the device on the bench, and the assistant answers about that specific board — reading its real parsed components, pins and nets — instead of guessing from general knowledge. Works with or without a board file: a symptom described in plain language already gets a structured diagnostic answer.

BoardFix is for people who repair laptops, phones, consoles and motherboards at component level — the ones who measure rails, chase shorts and read schematics, not the ones who swap modules. It runs in the browser, including on a phone at the bench.

## What makes it different from a general AI chat

**It is grounded in the actual board.** The assistant reads the parsed component list, pin list and nets of the uploaded file. Asked about a rail, it names the nets that really exist on this board.

**It checks itself and admits misses.** Before an answer reaches the technician, named parts and nets are verified against the board's real data. If the assistant referred to something that does not exist on this board, that is flagged in the answer rather than passed off as fact. Plausible-but-invented part numbers are the expensive failure mode in repair work — a technician sent to probe a component that isn't there loses hours — and the product is built specifically against it.

**It refuses to invent pin numbers.** Whole families of board formats carry no pin numbering at all. In those files the assistant will not produce a pin number even when the package pinout is well known; it gives the measuring point as "net on part" instead, which is a real address the technician can find.

**It opens files other viewers refuse.** Several proprietary and encrypted board formats are parsed directly, including ones common tools fail on.

## What technicians use it for

- Dead board, no power: which rails to measure, in what order, and what each reading rules out
- Short circuit on a power rail: locating the shorted part by resistance, voltage injection and thermal methods
- Reading a schematic: finding which controller generates a given voltage, and landing on that page of the PDF
- Identifying a chip from its marking and pulling its datasheet
- Liquid damage, charging faults, no display, boot-loop and power-sequence problems
- Questions asked with a photo: a board close-up, a thermal image, or a pinout screenshot from another boardview tool

## Features

**Board viewer.** Components and nets on both sides of the board. Click a part or a net and its entire path lights up across the board. Search by component or net name. Rotate, mirror, switch sides.

**Measurements logged in the chat.** The assistant states what to measure and where; the technician types the multimeter reading straight into the chat, and the next diagnostic step comes back based on the actual values. The diagnostic loop stays in one place instead of being retyped into a chat window.

**Schematics that open themselves.** A PDF schematic can be opened beside the board. Ask which controller makes a rail, and the assistant searches the whole document on its own — not only the page on screen — then scrolls the viewer to the page it found, so the technician is looking at the circuit instead of reading a page number. Any region of the schematic can be clipped with the scissors tool and sent into the chat as an image.

**Voice and camera.** Questions can be dictated, and a board photo taken from the phone or a USB microscope, without leaving the bench or switching apps.

**Sessions that come back whole.** Reopening an old chat restores the working state: the same board, the same schematic page, the same zoom and the selected part. A repair interrupted on Friday continues on Monday.

**Knowledge base of solved cases.** Finished repairs can be saved as cases. When a similar symptom comes up later, the assistant cites the earlier case explicitly — stating what it ended with, and marking it as another board's repair rather than a fact about the current one.

**Datasheet database.** Chip datasheets, free on every plan including the free one, with no plan limits.

**Discussion mode.** Besides strict diagnostics, hypotheses can be talked through the way they would be with a colleague at the next bench.

**Thinking mode.** Deeper analysis for hard cases, on paid plans.

**Personal cloud library.** Board files and PDFs stored in folders and reachable from any device, on paid plans.

**BiosFix — BIOS dump analysis and repair.** A separate paid service, independent of the subscription plans. Send a dump read from the chip with a programmer (an archive is fine) and it is analysed: vendor, regions, and whether the block holding the machine-specific data survived. If the dump is damaged, it is repaired — the serial number, UUID and MAC are transplanted into a clean official image and the checksums recomputed. Finding the official image is not the technician's job. The analysis costs €5 and is charged in any case because it is always performed; the repaired file unlocks after a further €10. If a dump cannot be repaired there is nothing more to pay. Usually ready within a day; the order, the report and the file stay in the account.

## Board file formats

Parsed directly: .brd, .bvr, .bdv, .gr, .cst, .fz, .cad, .tvw, .asc, .bv2, and BoardFix's own .bfx. A .zip, .rar or .7z archive can be uploaded as is — the board file or PDF schematic inside is picked out automatically. A PDF schematic opens in the built-in viewer. Every format is available on every plan, including free — paid plans differ by AI usage and storage, never by which files you may open.

## What BoardFix does not do

Worth knowing before choosing it, so the tool matches the job:

- **It does not draw or reverse-engineer schematics.** It will not produce a schematic, a CAD/PCB file or a drawing from photos of a board. It works with board files and PDF schematics that already exist, and from photos it identifies parts and helps find the fault.
- **It does not supply board files or schematics.** The technician brings the boardview or PDF for their device; BoardFix opens and reads it. Without one, the assistant still diagnoses from the symptom and photos, but cannot name the nets of that exact board.
- **It is not a PCB design tool.** No layout editing, no Gerber export.
- **It does not repair the device remotely.** It tells the technician what to measure and what the readings mean; the hands, the meter and the soldering iron are theirs.

## Plans

Per month. Board viewing in all formats, the PDF viewer and the datasheet database are included everywhere, free plan included. The free plan's AI questions are a one-time allowance per account, not a daily one: once they are used up, asking the assistant requires a paid plan.

- **Free (€0)** — 8 AI questions in total (a one-time allowance, it does not reset), 5 boards in history
- **Plus (€9.99)** — 25 AI questions per day, thinking mode, personal library (10 GB), PDF history (50)
- **Pro (€19)** — 48 AI questions per day, more thinking mode, library (50 GB), PDF history (150)
- **Max (€48)** — 150 AI questions per day, most thinking mode, library (200 GB), PDF history (500)

## Languages

Interface in English, Russian, Latvian, Spanish and Portuguese (Brazilian). The assistant replies in the language the question was asked in, whatever language the board data is in.
