Contrivance Inc · New York

Where software meets silicon.

Contrivance builds AI systems and the machines they run on: multimodal models that understand video, audio and text, with software tuned to the hardware underneath.

Talk to us

A New York corporation since 2017. We build and run our own inference: models, pipelines and the servers they sit on, so what we ship is ours end to end.

What we build

AI that handles the whole signal.

Most systems read text. Ours take the video, the sound and the words at once, and turn them into something a person can search, summarise and act on.Services in detail

AI software as a service

Services built on software using artificial intelligence for processing, analysing and generating video, image, audio and text data. Transcription, visual understanding, titling, summarisation, recommendation.

Software & systems development

Development of software and the systems it runs on: from on-device mobile apps to the GPU inference servers behind them, specified, built and tuned by us. We run what we build.

Research & consultation

Research and development, and consultation related to it, in artificial intelligence, machine learning and multimodal neural network systems.

Contrivance Labs

The research arm. Where the models get trained, evaluated against real material, and made small enough to run on hardware we own.

  • Multimodal understanding

    Joint models over video frames, speech and on-screen text, built so that a query about a place or a moment can be answered from what was actually recorded.

  • Self-hosted inference

    Serving open-weight models on our own GPUs rather than renting capacity, and measuring what that costs per user.

  • Retrieval over real footage

    Search that reads the video, not just its caption.

  • Evaluation

    Blind, corpus-grounded comparisons before anything changes what a model sees.

Product

Cohlta: watch the city, ask the city.

Our first product, and the reason the models exist. Cohlta is two co-equal halves: a feed of real video pinned to real places, and an AI concierge that answers from it. The feed builds a record of the city; Ask is what makes that record answer questions.

COHLTA AI

The videos people are making around you, a map of what is actually on, and an assistant that has watched the footage, so it answers about a street or a night from what was recorded there, not from a guess.

  • The feed

    Real video pinned to the place it was shot. Pulse for the city, Friends for your people.

  • Ask

    A city concierge grounded in that footage, live events and the open web.

  • Map and plans

    What is on, where, and what it looks like.

  • Social

    Messages, stories, and end-to-end encrypted calls.

About

A small company that builds the whole stack.

Contrivance Inc. is a New York corporation founded in 2017. We build the AI, the software it runs in, and the machines it runs on, and we use it ourselves before anyone else does. If you're working on something that has to understand video, audio and text together, we'd like to hear about it.
