Live · AI fault diagnosis & technician matching
Film a 15-second Fault Reel of the leaking pipe, warm fridge or sparking socket. Faultlens identifies the likely fault, flags safety risks and matches you with a verified technician who repairs exactly that — from $1 a month.
15-second Fault Reels
Film the problem and say what you notice. No jargon needed.
AI fault brief
Item, likely cause, urgency and safety notes in plain language.
Skill-matched technicians
Matched by the exact repair, not a generic "handyman" listing.
From $1 a month
One flat plan for households. Repairs are quoted upfront by the technician.
Before the right technician
Most repair delays start with the wrong person turning up. Faultlens reads what is actually broken and sends it to the trade and skill that fixes it.

The problem
People can see that something is broken but rarely know what the fault is called or which trade repairs it. Technicians arrive without detail, diagnose on the first visit and return with parts on the second. Every extra call-out costs the customer money and the technician a paid slot.
Without Faultlens
With Faultlens
You describe a fault you cannot name: "it makes a noise and stops".
A 15-second reel shows the fault. Faultlens names the likely cause for you.
You call three people before finding someone who repairs that exact thing.
Jobs go only to technicians whose verified skills match the fault brief.
The technician visits, diagnoses, then returns another day with the part.
Technicians watch the reel first, so they quote and bring the likely part.
You have no record of what was fixed, by whom, or for how much.
Every job keeps the reel, the brief, the quote and a before/after repair reel.
Product
Each part of Faultlens removes one reason repairs go wrong: an unclear description, the wrong trade, a missing part or no record afterwards.
Record up to 15 seconds of the faulty item and narrate what you see, hear or smell. Photos and a short note work too.
Video captures sounds, error codes and leaks that a text description misses — so the first diagnosis starts from evidence.
Faultlens identifies the item, reads visible labels and error codes, and drafts the likely cause, alternatives, urgency and the trade needed.
You review and edit the brief before it is shared, so technicians receive a clear, accurate job description.
Sparks, gas smells, water near electrics and smoke are flagged immediately with stop-use guidance before any matching starts.
Some faults should not wait for a quote. Faultlens tells you when to switch off, step away or call emergency services.
Jobs are matched on trade, specific skills and brands, distance, availability and completed-job rating.
A compressor fault goes to a refrigeration technician, not to whoever is nearest. Fewer wasted visits for both sides.
Matched technicians watch the reel and brief, then send a quote range and the parts they expect to bring.
You compare like-for-like quotes and the repair is more likely to be finished in one visit.
After the repair the technician adds a short fix clip. Faultlens assembles a captioned before/after repair reel.
You keep proof of the work for warranties and landlords; technicians build a video portfolio of real repairs.
Landlords and managers share a reporting link. Tenants submit Fault Reels that arrive triaged and ready to assign.
No more chasing tenants for photos or forwarding vague messages to contractors.
How it works
The whole journey runs in the browser on any phone or computer — nothing to install.
Step 1
Open Faultlens in your browser and record a 15-second Fault Reel. Say what happened and when it started.
Step 2
Frames and narration are analysed to identify the item, visible damage, error codes and likely causes.
Step 3
Check the fault brief, urgency and safety notes. Edit anything that is wrong, then confirm.
Step 4
Compare matched technicians, their skills, ratings and quotes. Book the one you trust.
Step 5
The repair, cost and before/after reel are saved to your history for warranty and future repairs.
Interactive demo
Pick a Fault Reel, run the analysis, edit the brief, then compare matched technicians and request a quote. This demo runs in your browser with fictional sample data — no video is uploaded and no AI service is called.

Who it’s for
Where the AI is used
Faultlens uses computer vision, speech recognition and a foundation model for one job: turning a short video into a fault brief clear enough to match and quote. Every brief is reviewed by the customer and confirmed on site by the technician.
Fault Reel video frames, spoken narration, photos and the customer’s note.
Object and label detection identifies the item, brand, visible damage, leaks and on-screen error codes.
Narration is transcribed so symptoms like “clicking”, “burning smell” or “since yesterday” are captured.
A foundation model combines vision labels, transcript and Faultlens’ fault taxonomy into a structured fault brief.
The customer confirms the brief; the technician confirms the diagnosis on site. The brief guides, it does not replace inspection.
Skill tags drive matching, and the confirmed result improves future briefs for similar faults.
Technology
Every Fault Reel is a small video-processing job: it has to be stored privately, transcoded, analysed by vision and speech models, turned into a brief and routed to the right technicians within minutes. Faultlens’ architecture on AWS uses serverless, event-driven services so each reel moves through that pipeline independently and cost scales with the number of faults reported.
Customers and technicians sign in and upload Fault Reels from the browser.
Reels are stored as private objects; jobs and briefs as structured records.
Each upload starts a workflow that normalises video and extracts key frames and audio.
Vision labels and transcripts are combined into a fault brief with urgency and skill tags.
Matching logic ranks technicians and alerts them; customers get quotes and updates.
Fault Reel workflow
Browser upload (signed URL) → S3 private bucket → S3 event → Step Functions
→ MediaConvert (normalise, key frames, audio) → Rekognition (labels, text) ∥ Transcribe (narration)
→ Bedrock (structured fault brief + safety flags) → DynamoDB (job + brief)
Customer confirms brief → API Gateway → Lambda matching → SNS / SES alerts → technicians quote → booking
Repair complete → fix clip → MediaConvert before/after repair reel → CloudFront delivery
Media is private by default and shared only with technicians matched to that job, via expiring links. Data is encrypted in transit and at rest, access is scoped by Cognito role and IAM policy, and customers can delete reels from their history.
Serverless compute and on-demand storage scale with the number of reels uploaded, so cost follows usage. The Step Functions pipeline processes reels in parallel and retries failed stages without losing the job.
Video is transcoded once and analysed on a handful of key frames rather than every frame, and older raw uploads move to lower-cost storage while the brief and repair reel are kept.

Team
Faultlens is built by two siblings who set out to make getting things fixed as simple as showing someone the problem.
Founder, Faultlens
Shalom founded Faultlens to fix a problem every household knows: you can see something is broken, but you cannot describe the fault well enough to find the right person to repair it. Shalom leads the company and its product.
Co-Founder, Faultlens
Precious co-founded Faultlens alongside Shalom. Building it as siblings, the two share one goal: make getting something repaired as simple as filming the problem and choosing a technician you can trust.
Get started
Faultlens is running now. Send your details and the fault, and the team will set up your Fix Pass, Property or Technician Pro account and get your first job matched.
