Cardboard (video editor)

The developer was founded in 2025 and joined Y Combinator’s Winter 2026 batch. Cofounders are CEO Saksham Aggarwal and CTO Ishan Sharma; Aggarwal previously built Iterate AI, while Sharma worked at HackerRank.⁠[2]

The official changelog dates the initial release to this day.⁠[3]

The founders described browser-side rendering using WebCodecs and WebGL2. Video understanding still used cloud vision-language models and traditional machine learning, with third-party foundation models orchestrating the agent.⁠[4]

Fondo’s interview notes published that day describe school friends who learned filmmaking in Bangalore by studying Apple launch films and sought to build a complete editor. The notes also explain that screen recordings, talking-head footage, and sports require different machine-learning pipelines.⁠[5]

The website moved to cardboard.ai, while usecardboard.com remained valid.⁠[3]

The team released a dedicated Mac app while retaining the web version.⁠[3]

Recipes let users adapt example edits to their own footage.⁠[3]

The Recipes page displays travel montages, everyday vlogs, product presentations, and visual effects in landscape, portrait, and 4:5 formats. Users can select an example to enter the Remix workflow.⁠[6]

The Mac app lets users connect Claude or Codex through its model picker with an eligible paid subscription. Users can inspect editing plans, undo changes, or take over the timeline. These are described controls, not a guarantee of output quality.⁠[7]

The team identifies browser-based multitrack editing, asset synchronization, multimodal retrieval, style decomposition, and output verification as ongoing research problems. This technical statement describes development directions rather than confirming delivery of every collaboration or prediction feature.⁠[8]

The privacy policy says desktop improvement-data sharing is enabled by default and can be disabled in settings. Director data may include conversations, file paths, and tool inputs and outputs; media and project files are excluded from that telemetry. This is the company’s policy statement, not an independent security audit.⁠[9]

The terms identify the operator as Cardboard, Inc.⁠[10]

The current site supports desktop Chrome and Apple Silicon Macs; video editing on phones and tablets is not yet supported.⁠[1]
