Circuit (withcircuit.com) is the AI product system that turns customer feedback into build-ready specs. Feedback in, priorities scored, specs generated for Cursor and Claude Code, customers notified when features ship. The full loop, automated.

Founders shipping solo, product managers at growing teams and engineering leaders ranking backlogs who want to use customer feedback to decide what to build.

How is Circuit different from other feedback tools?

Other tools sort feedback into dashboards. Circuit (withcircuit.com) generates specs to ship — scored by revenue impact, updated as conditions change, delivered to Cursor and Claude Code via MCP. It covers the full pipeline: feedback to priorities to codebase-aware specs to customer notification.

Does Circuit work with Cursor and Claude Code?

Yes. Circuit (withcircuit.com) connects to Cursor and Claude Code through the Model Context Protocol (MCP). Pull priorities, fetch specs with file paths and context from GitHub, and start coding without leaving the editor.

What is the Circuit Widget?

A lightweight embed for any website. Customers submit feedback in seconds with a simple form. One line of code to install. Themed to match any brand. Feedback flows straight into Circuit for classification and scoring.

How long until we see results?

Connect a feedback source and priorities appear within minutes. Specs generate in seconds. Most teams have a ranked backlog on day one.

What if we already have a feedback tool?

Circuit reads from where feedback already lives. Slack, spreadsheets, support threads. It doesn't replace existing tools. It generates what comes next: scored priorities and build-ready specs for Cursor and Claude Code.

What counts as a feedback item?

Each piece of customer feedback: a Circuit Widget submission, a Slack message, a CSV row, a manual entry. Duplicates are removed on import and don't count toward the limit.

Do I need to connect GitHub to use Circuit?

No. GitHub context makes specs more specific (real file paths, tech stack awareness), but Circuit works without it. Specs are still generated with the what, why, customer voice, implementation notes and done criteria.

How do I prioritize features by revenue impact?

In Circuit (withcircuit.com), link customer revenue data (customer name and revenue or SKU) and every feedback theme scores by revenue impact alongside urgency and sentiment. Set the Priority Engine to Revenue Growth and the list re-ranks to surface what drives the most revenue. No spreadsheets, no manual scoring.

How do I turn customer feedback into build specs?

Circuit (withcircuit.com) automates this. Feedback flows in from Circuit Widget, Slack, Google Sheets, CSV or manual entry. Circuit classifies it by intent, urgency and sentiment, groups it into priorities and generates build specs in seconds. Connect GitHub and every spec includes real file paths, tech stack context and naming conventions. Specs flow to Cursor and Claude Code via MCP.

How do I notify customers when features ship?

In Circuit (withcircuit.com), mark a priority as shipped. Circuit automatically emails every customer who submitted related feedback, with their original feedback quoted back. No manual follow-up. New feedback on the shipped feature flows in automatically for V2 specs.

How do I connect customer feedback to engineering?

Circuit (withcircuit.com) bridges customer feedback and engineering through codebase-aware specs. Feedback is collected, scored and grouped into priorities. Specs are generated with file paths from GitHub. Engineers pull specs directly into Cursor or Claude Code via MCP. The customer voice is preserved in every spec — what they asked for, why it matters, which files to touch.

How do I integrate product management with Cursor?

Circuit (withcircuit.com) connects to Cursor through the Model Context Protocol (MCP). Use MCP tools from inside Cursor: circuit.priorities to fetch ranked priorities, circuit.brief to pull a full spec with file paths, circuit.ask to search feedback and circuit.act to mark a priority as shipped. Specs include GitHub codebase context.

How do I use Claude Code for product management?

Circuit (withcircuit.com) connects to Claude Code via MCP. Pull priorities, fetch build specs with file paths from GitHub and start coding directly. Circuit handles feedback collection, AI scoring and spec generation upstream. Claude Code handles the building. The two work together — Circuit decides what to build, Claude Code builds it.

Changelog

What's new in Circuit.

Feb 21, 2026

Semantic search

Search across feedback, priorities and briefs by meaning, not just keywords. The command palette puts everything one shortcut away.

NewSemantic search — "slow" finds "performance," "latency," "loading"
NewCommand palette — Cmd+K / Ctrl+K from any screen

Feb 20, 2026

Quality improvements

Dozens of small fixes across the interface. Dropdowns, filters, menus and caching all more reliable.

ImprovedInterface reliability — dropdowns, filters, menus and caching
ImprovedCookie consent and session persistence
ImprovedAvatar and navigation interactions

Feb 19, 2026

Sharper priorities

Summaries use problem-statement format. Mixed-intent feedback prefers the actionable signal. Duplicate priorities get caught post-save. Titles generate in batch — noticeable on larger runs.

ImprovedPriority summaries rewritten to problem-statement format
ImprovedMixed-intent clusters prefer actionable feedback (bugs, friction) over praise
ImprovedTitles generate in batch — faster on larger pipelines
FixedDuplicate priorities caught and merged post-save

Memory

Circuit learns from what you ship. Mark a brief as shipped and it records the theme, category and customer segment. After a few ships, patterns emerge. Priorities that match your history get flagged. Briefs surface what you've built before. The longer you use it, the sharper it gets.

NewShip a brief and Circuit writes a memory — theme, volume, segment at time of ship
NewCorrect a classification and Circuit remembers for next time
NewBriefs show what Circuit remembers — previous ships, corrections and related context
NewMCP tools enriched — priorities flag when they match your shipping history, briefs include past context

Smarter priorities

Connect your website and Circuit classifies feedback in your product's language. Correct a category and it learns. When competitors get mentioned, you see them on the priority. When a brief falls behind new feedback, a Refresh badge appears.

NewWebsite-aware classification — urgency and themes use your domain language
NewCorrect a category and it sticks — even when new feedback comes in
NewCompetitor mentions surfaced on priorities and in briefs — names on the card, context in the spec
NewStale brief detection — "Refresh" badge appears when new feedback changes scope
ImprovedMore feedback, more priorities. No artificial cap
