What is ManualNinja?

ManualNinja is a retrieval-augmented AI assistant for technical documentation. You feed it the PDF manuals your team already relies on, and it gives every technician an instant, expert answers channel — one that never hallucinates beyond the source material, because every claim is tied to a specific page in a specific manual.

It is purpose-built for appliance installers and repair technicians who need fast, accurate, verifiable instructions on the job. Upload a manual, ask a question in plain language, and get a step-by-step answer with a direct link to the source page.

Now with AI vision: snap a photo of a device label, error screen, or nameplate, and ManualNinja will read it, identify the device, extract error codes, and find the right answer in your manuals.

Core capabilities

RAG chat assistant

Questions are embedded and matched against your manual library, then a large language model composes a precise answer from the retrieved excerpts.

AI vision (new)

Upload a photo of a device label, error code display, or nameplate. The AI reads it, identifies the device, and searches your manuals automatically.

Page-specific citations

Every answer includes a clickable link to the exact manual and page number, so technicians can verify and read more context.

Multi-tenant organizations

Each customer gets an isolated workspace. Manuals, chat history, and usage are scoped per organization — no data leaks between tenants.

Google & LinkedIn login

Technicians can sign in with their Google or LinkedIn account — no new password to remember. One click and they’re in.

Self-service signup

New customers can register independently, verify their email, and start using the free trial immediately — no sales call needed.

Stripe subscriptions

Monthly recurring billing through Stripe. Customers can upgrade, downgrade, or cancel anytime via the self-service billing portal.

Tier-based limits

Questions per month, storage, question length, and manual count are all controlled per subscription tier. Upgrade for more.

Bot protection

Google reCAPTCHA, email verification, and IP rate limiting protect your account from automated abuse and credit consumption.

Multilingual — ask in your own language

ManualNinja automatically detects the language of your question and responds in the same language. Your manuals may be in English, but your technicians can ask in Dutch, German, French, or any other language — and get a clear, natural answer back.

Ask in any language

Type your question in Dutch, English, German, or any other language. The AI detects the language automatically and answers in that same language — no configuration needed.

Manuals stay in their original language

Upload manuals in any language. The AI translates the relevant excerpts on the fly and presents the answer in the language of the question. Your English manuals work for Dutch-speaking technicians.

How it works

From PDF to cited answer in four steps

1. Upload manuals

Admin uploads PDF manuals — installation guides, service manuals, error code sheets.

2. AI indexes

Each PDF is parsed, chunked, and embedded into a vector database for semantic search.

3. Ask or snap

Technicians type a question or upload a photo of a device label or error screen.

4. Get answers

The AI answers with step-by-step instructions and a direct link to the source page.

AI Vision: Snap. Identify. Solve.

Available on Business and Enterprise plans

A technician encounters an unfamiliar error code on a device display. Instead of searching through manuals, they simply snap a photo with their phone and upload it to the chat.

ManualNinja’s AI vision model analyzes the image and extracts:

  • Device type — what kind of equipment is this
  • Brand & model — from nameplates and labels
  • Error codes — from digital displays and LED patterns
  • Technical specs — voltage, wattage, pressure, etc.
  • All visible text — full OCR of labels and stickers

The AI then automatically searches your manual library using this information and provides a targeted answer with the right repair procedure.

Why it matters

Field technicians often can’t identify a device model from memory, especially with older equipment or rebranded units. A photo eliminates the guesswork:

  • No more calling the office to look up a model number
  • Error codes are read automatically — no manual transcription errors
  • Nameplate data (serial, voltage, production date) is captured instantly
  • The AI matches the photo data to the right manual page
  • Works with any device that has a label, screen, or nameplate

It’s like having a senior technician looking over your shoulder, who happens to have memorized every manual in your library.
