History

From explainer videos to ads.

Same company. What we make changed.

  1. 2024

    An explainer video tool

    KnowlifyAI, Inc. launched a tool that turned documents and PDFs into explainer videos.

  2. 2025

    Backed by Y Combinator

    Knowlify joined Y Combinator's Summer 2025 batch.

  3. 2026

    From software to done-for-you

    We stopped selling software and started doing the work: custom videos first, then ads.

  4. October 2026

    Ads only

    We retired the explainer, training and self-serve products to make only ads.

Explainer videos

If you knew Knowlify for explainer videos.

We no longer make explainer, training, onboarding, e-learning or patient-education videos. The old explainer guides are gone.

For a single brand film or an explainer video, try a production studio or a self-serve AI video tool.
