SUBJECT Signal Brief: Doop puts AI agents on the canvas beside you
Doop
Doop — launched on Product Hunt September 2 — is an open-source infinite canvas where AI agents like Claude and Codex design beside you live, streaming frames onto the canvas, reviewing each other's work, and sharing one memory of your decisions, design taste, and context.
WHY IT MATTERS Design exploration stops being a handoff — the PM sketches the flow while agents draft variations on the same canvas, so the mock that reaches the stakeholder review is already three iterations deep.
doop.design →Caddi
Caddi — a top Product Hunt launch of August 28 — turns a narrated screenshare into a production agent: show the task once and it learns the process, builds the automation across your real tools, and takes updates in plain English, with every run logged and every permission scoped.
WHY IT MATTERS The recurring ops work no roadmap ever funds — compiling the launch checklist, syncing fields across tools, triaging inbound — becomes an agent you trained by doing the task once, not an automation project.
trycaddi.com →Keiki
Keiki — launched September 1 — lets you build one customer-facing AI agent and deploy it across SMS, iMessage, WhatsApp, Slack, Telegram, and email, with your knowledge, memory, tools, and boundaries plus one place to inspect conversations and approve sensitive actions.
WHY IT MATTERS A support or onboarding agent stops being six channel integrations — you build it once with explicit boundaries and a human-approval path, and it meets customers where they already reply.
onkeiki.com →Sider Code
Sider Code, new in the Sider Chrome extension and launched September 1 — reshapes any website with plain words: tell it how a site you rely on should work and it understands the page, writes the code, and makes the change, saved and under your control.
WHY IT MATTERS The tools your team cannot change — the analytics dashboard, the legacy admin — become malleable, so a PM can prototype the workflow they wish existed without filing a ticket or waiting on a vendor's roadmap.
sider.ai →Enter Pro
Enter Pro — a top Product Hunt launch of August 27 — is an AI-native platform that turns an idea into a working product in one continuous workspace: plan, build, preview, launch, and scale apps, sites, and custom AI agents with models, databases, auth, hosting, payments, and analytics built in.
WHY IT MATTERS The validation prototype stops dying at the demo — the same workspace carries it from idea to a launched, metered product, so a PM's experiment can become a real surface without a rebuild.
