YappJam

YappJam is a multiplayer AI workspace where product, design and engineering teammates share one live session with models like Claude, Codex, Gemini and Grok, preview the build, and ship to GitHub via pull request.

YappJam is a browser-based workspace that puts a whole product team inside a single AI coding session. Instead of a product manager writing requirements, a designer exporting mockups and a developer interpreting both weeks later, everyone joins one room and contributes to the same conversation with the AI. Participants can see each other typing, talk over built-in voice and video, and dictate prompts with speech-to-text. In practice, a session starts from scratch or by cloning a GitHub repository. The host shares a room code, teammates join, and the AI agent reads, writes and edits files directly in the workspace. The homepage demo shows a product lead describing a churn problem, a designer simplifying a Figma flow and a developer asking for the result to be built on a specific route, with the agent scaffolding the feature, running a live preview and opening a pull request. The dev server starts automatically, so the running product updates as changes land. Figma designs can be connected so the model sees visual context, and branches can be pushed to GitHub without leaving the session. The workspace supports models from Anthropic, OpenAI, Google and xAI, and providers can be switched mid-session. Plans are priced by monthly token allowance, with a bring-your-own-keys option, and the Team plan adds member management and per-seat billing. The product states that source code stays in the user's own GitHub repository and is not stored permanently. YappJam is aimed at cross-functional groups of product, design and engineering people, including members who do not code. Its main contrast is with single-user assistants such as Cursor or ChatGPT, which it positions as built for one person at a time. Teams that already have established developer-only workflows may find less benefit, while groups that lose time to handoffs are the intended audience.
