Sitara

In development · pre-launch testing

AI creator matching and performance attribution for subscription apps and games. Brands find creators by predicted paid conversions, not follower counts, and pay them for verified results.

02Technology

AI matching technology

Understand each side, narrow the field, rank by predicted results and explain why. Matching runs in five steps.

  1. 1. Understand the app

    Gemini reads the app listing and brief

  2. 2. Understand each creator

    Multimodal analysis of public content

  3. 3. Retrieve candidates

    Shared embedding space and vector search

  4. 4. Rank by predicted results

    Trained on verified payments, refunds and renewals

  5. 5. Explain and act

    Plain-language reasons, one-click invitations

Three principles

  • Only public or creator-provided data

  • Unknown is shown as unknown, never guessed

  • People make the final decision; AI shortlists and explains

All source code is developed in-house and owned by NStar.
