VertesseraSign inA card for every thought.
Vertessera is a card-based editor for writing and editing with an AI model. Each card holds one thought. Axes line those cards up into a text. Edits and the conversation about a card stay in one history, model sees this history and all the text at once.
Editing text with AI is difficult: long texts fall apart in the chat interface—edits, new segments, and discussions all get jumbled together in a single feed, making it nearly impossible to determine which version is the current one. Agent mode presents the opposite problem: edits are detached from the text itself and turn into a separate management process.
Vertessera keeps the text, its versions, and the AI dialogue within a single structure without conflating them. The model operates directly on the current card and its context, with the output immediately becoming a revision or a new card. This results in inference with virtually no overhead—there is no need for tool calls here.
To the left, an AI collaborator works with you card by card. Instead of confronting an empty screen, you talk through nascent ideas, explore alternative angles, and test drafts in real time.
Every conversation and proposed revision stays anchored directly to the thought itself. Context is never lost, and you always have an attentive partner ready to help you shape the next sentence.
Hypertext without all the fuss.
To the right, each card reaches out to the rest of your thinking. Direct ID links weave references across axes without breaking linear flow.
Alongside them, semantic embeddings index every card by meaning. Vertessera surfaces related thoughts automatically—uncovering echoes across axes, suggesting relevant context, and revealing connections you never had to manually wire together.
