# Keep what your company learns. ZeroWidth closes the gap between what your company learns and your next change, so every lesson is kept, proved and put to work. [Work with us](https://zerowidth.ai/work-with-us) [Get started](https://console.zerowidth.ai/start) ## Or try it yourself in your AI tools, over MCP, a skill or a plugin - [Claude](https://zerowidth.ai/docs/connect/claude) - [ChatGPT](https://zerowidth.ai/docs/connect/chatgpt) - [Cursor](https://zerowidth.ai/docs/connect/cursor) - [GitHub Copilot](https://zerowidth.ai/docs/connect/vs-code) - [Any MCP tool](https://zerowidth.ai/docs/connect/other-tools) ![In ChatGPT, Ana Ruiz agrees to drop the card step from signup. In ZeroWidth the decision is watched for 28 days and marked Worked: trial starts went from 318 to 412 a week. Later, when someone asks Claude whether to put a card check back on signup, Claude warns that it would undo that and suggests blocking throwaway emails instead.](https://zerowidth.ai/hero-poster-light.webp) ## Two ways to start Most companies start by mapping their business with us. If your team already works in AI tools, you can connect ZeroWidth yourself. ### Map your business with us We interview your people, map how the work runs and what each step costs, and price each change before it ships. Then we connect ZeroWidth, so every result is kept and checked. Quoted per round of mapping. [Work with us](https://zerowidth.ai/work-with-us) ### Connect ZeroWidth yourself Connect the AI tools your team already uses. ZeroWidth keeps each decision from day one and checks it against your numbers. Plans priced by team size, starting free. [Get started](https://console.zerowidth.ai/start) ## Your team's decisions are already written down. Every chat, thread and document your team writes holds the decisions behind the work. Right now, those decisions are waste. - Chats with Claude, ChatGPT and Copilot - Replit and other AI agents - Your engineers' coding agents - Slack and Notion - Google Docs and Word - GitHub, Jira and Linear - Meetings and email - Then those decisions sit unused. ZeroWidth puts those decisions to use. ## ZeroWidth finds the decisions in what your team wrote. In a chat, a thread or a commit, ZeroWidth picks out what the team chose to do, and which of your numbers the choice was meant to move. Raise the Pro plan from $20 to $25 a month. Growth, in ChatGPT. Revenue Retire preview environments. Engineering, in a coding agent. Page load Ship the after-hours bot behind a feature flag first. Support, in Slack. Support tickets Replace search analytics with fuzzy matching. Product, in Linear. Page load ## ZeroWidth maps where your team's work is happening. Decisions gather into areas of the business, like support tickets or the edge cache. Each week, ZeroWidth shows which areas are heating up and which are cooling down. Acme / Map ![Acme's map: every area Acme's teams decide about, as clusters of decisions, the latest standing out](https://zerowidth.ai/img/acme-map-light.jpg) ## ZeroWidth finds which decisions worked. A decision worked when your numbers moved the right way, by more than they usually move. The best and worst of one quarter: Best Retire preview environments. Page load moved 17.7 times the usual swing, the right way Replace search analytics with fuzzy matching. Page load moved 17.7 times the usual swing, the right way Pause work on the Kubernetes cluster until autoscaling is done. Page load moved 17.7 times the usual swing, the right way Worst Add reduced motion to the accessibility audit for teams over fifty seats. Support tickets moved 6.4 times the usual swing, the wrong way Ship the after-hours bot behind a feature flag first. Support tickets moved 6.2 times the usual swing, the wrong way Retire the Android app for enterprise accounts. Support tickets moved 6.1 times the usual swing, the wrong way ## Your team's AI tools can see what worked. Before the next decision, your team's agents check what your team already tried, and what happened. Support, in SlackTry the after-hours bot with ten customers first. The last launch raised tickets. Product, in ClaudeRaising Pro to $25 lifted revenue 25%, so a Basic rise has a good record behind the idea. Engineering, in a coding agentKeep preview environments off. Retiring them was one of your best decisions last quarter. ## ZeroWidth adapts to how your business works, and finds the metrics and decisions that moved things in the right direction.
