Product Weaver

Free plugin for Claude, ChatGPT and Codex, and GitHub Copilot

What to build next is hiding in your transcripts.

Product Weaver is a free plugin for your AI assistant. Point it at your customer interview transcripts and get a map of what customers are trying to get done, where they struggle and what they use today. Every claim is backed by their exact words.

No terminal needed. In the Claude desktop app, open Customize, then Plugins. Choose Add marketplace, paste this line and install productweaver. Then, in Cowork, choose a folder and say: Help me get started with Product Weaver.

Then say: “Process the interviews in my Interviews folder.”

Example study: one sentence from an interview becomes a job, a step, an outcome and a current solution on the map.

Sound familiar?

  • Transcripts pile up

    Ten calls, ten files, and no time to read them twice.

  • AI summaries sound right

    But you cannot tell which words the customer really said.

  • The team debates opinions

    The loudest voice wins, not the evidence.

What you get from a few transcripts

A knowledge base your whole team can check, and a map that shows it.

  • Quotes you can trust

    Each quote is checked word for word against its transcript. If the words are not there, it is refused.

  • A job map

    The jobs your customers are trying to get done, step by step.

  • The outcomes they want

    How they measure success at each step, in plain statements.

  • What they use today

    Tools, spreadsheets, people and workarounds. Also what they gave up, and why.

  • What to ask next

    The steps where your evidence is thin, so your next calls fill the gaps.

  • One map to share

    A single HTML file. It opens in any browser and grows with every batch of interviews.

Three steps. No new tool to learn.

  1. 1

    Install

    Copy the line for your assistant and use it once. In the Claude app you paste it; no terminal needed.

  2. 2

    Ask in plain words

    No syntax to learn. Say what you want.

    “Process this week's discovery interviews in the Interviews folder.”

  3. 3

    Review and open the map

    You get a review sheet with the decisions that wait for you, and the discovery map.

Made for people who talk to customers

  • Founders

    Know what to build before you spend the runway.

  • Product managers

    Walk into planning with evidence, not a hunch.

  • Advisors and coaches

    Give every startup you work with the same evidence-first method.

Your data stays yours

The plugin sends nothing unless you turn on usage statistics for a study, and even then never your interviews, names, quotes, prompts or file names. Your transcripts and the knowledge base stay in a folder on your machine. See what it runs.

Questions

What is Product Weaver?

Product Weaver is a free, open-source plugin for Claude, ChatGPT and Codex, and GitHub Copilot that turns customer interview transcripts into a jobs-to-be-done knowledge base, with every quote checked word for word against its transcript. It finds the jobs your customers are trying to get done, the steps of each job, the outcomes they measure success by and what they use today, and shows it all in a discovery map you can share.

How do I analyze customer interviews with an AI assistant?

Install the plugin, open the folder with your transcripts, and ask in plain words, for example “Process the interviews in my Interviews folder.” The assistant reads each transcript and pulls out the jobs, steps, outcomes and current solutions with the exact quotes behind them. The plugin checks every quote against its transcript, then writes a review sheet and a discovery map. The interview analysis guide shows each step, with or without the plugin.

How is this different from asking an assistant to summarize interviews?

A summary is gone when the chat ends, and you cannot tell which words the customer really said. Product Weaver keeps a knowledge base that grows with every batch of interviews, links each finding to the people who said it, and refuses any quote that is not word for word in its transcript. Anyone on your team can check every claim.

How is it different from Dovetail or a research repository?

Research repositories such as Dovetail are hosted services where a team stores, tags and searches its research. Product Weaver is a free plugin for the assistant you already use. It keeps the files on your machine and applies one method, jobs to be done, to turn transcripts into a job map, desired outcomes and value themes. See the full comparison.

What do I need?

Claude (the desktop app or Claude Code), ChatGPT and Codex, or GitHub Copilot, and Python 3.9 or newer on your computer. Your transcripts can be .md, .txt, .docx or .pdf files. The install guide has the details.

I use the Claude app, not Claude Code. Does it work?

Yes. In the Claude desktop app it works in Cowork, and you install it from the Customize menu, with no terminal. If you use claude.ai in a browser, run the plugin in the desktop app: it works with the files on your computer. The install guide has the steps.

Which assistants does it work with?

Claude: Cowork in the Claude desktop app, and Claude Code (terminal, VS Code, JetBrains and the Code tab of the desktop app). Codex CLI and the ChatGPT desktop app. GitHub Copilot CLI and VS Code. Chat on claude.ai in a browser is not tested yet.

How many interviews do I need?

Start with the few you have. Add more whenever you like: each batch goes into the same knowledge base, and the map grows.

Do my transcripts leave my computer?

Not through the plugin. It sends nothing unless you turn on usage statistics for a study, and even then never your interviews, names, quotes, prompts or file names. Your assistant works with your files as it always does.

What method is behind it?

Jobs to be done, in the Outcome-Driven Innovation (ODI) style. You do not need to know the method to start. Jobs to be done, explained covers the terms in plain words.

Is it free?

Yes. The plugin is open source under the Apache 2.0 license.

What comes next?

Sign-in and shared workspaces on this site, so a team can keep one knowledge base and reach it from any assistant. Until then, there is nothing to sign up for.

Got transcripts? You are one line away.
