Teams collaborating on live products
Free forever

Platform live
Jira · Linear · Slack · GitHub · Claude Code
Works on any URL
localhost, staging, production — no setup
Your agents know the whole picture.
Connect any AI agent over MCP with a workspace token. It carries the full context of your system and business goals, turns scattered feedback into clear options, and gives customers, stakeholders, and your team what they need to decide in minutes — with control over every outcome.
Full context, on tap
Agents read the entire thread — feedback, screenshots, the element and its source, plus the system and goals you give them. No re-explaining.
Feedback becomes options
They surface root cause, trade-offs, and a proposed fix — the context decision-makers actually need to make the call.
You stay in control
Approve it, route it to Jira, or have the agent open the PR. Humans decide; agents do the legwork.
The "Place order" button does nothing on mobile. Lost my cart twice.
Root cause: onSubmit is gated behind a desktop-only hover state in Checkout.tsx:88. Two options:
- · A. Bind to tap (1-line) — ships now, low risk.
- · B. Refactor the CTA state — cleaner, ~1 day.
Go with A now, open a ticket for B. Ship it.
Collaboration without seat fees.
Your whole team — designers, devs, PMs, clients — collaborates directly on the running product. Free forever.
Free for your team
Every collaborator. Always free.
Most tools charge per seat. Yocoolab doesn't. Invite your entire team — devs, designers, PMs, clients, stakeholders — and nobody pays a seat fee. Ever.
No migration needed
Works on top of what you have.
Yocoolab is a collaboration layer for your live product — no imports, no file conversions, no syncing. It works alongside your design system, Storybook, or component library exactly where they already live.
Feedback to shipped
From comment to PR in minutes.
Click any element, leave feedback, and route it to your AI agent, Jira, or Linear. Your agent generates the fix, your team reviews it, the PR lands. No copy-pasting feedback into tickets.

How It Works
Go from "the button looks off" to a tracked issue with full context in three steps.
Connect
Link your GitHub repos, deployed URLs, and project trackers. Connect Jira, Linear, Slack, and Telegram in a few clicks. Setup takes under a minute.
Click
Pin comments on your live app or hit "Send to Agent" to capture any element. Share a link and stakeholders can comment without creating accounts. Screenshots, selectors, and styles are captured automatically.
Ship
Send it to Jira, Linear, or your AI agent. Issues get full context. Your agent generates PRs. Your team stays aligned with real-time updates in Slack and Telegram.
Feedback that lives on the real product
Pinned to the exact element, in the exact state — with the context an engineer needs to ship the fix.
Pin Comments Anywhere
Drop contextual feedback on any element of your live app — localhost, staging, or production — with pixel-perfect precision and no code changes.
Auto-Capture Screenshots
Every comment captures a screenshot with the pin overlay, attached to the thread and synced to Jira, Linear, and Slack for instant visual context.
Threaded Discussions
Reply, resolve, and react with emoji. @mention teammates to loop them in — with notifications that land where they already work.
Jira, Linear, Slack & Telegram
Send feedback to Jira or Linear in one click. Slack and Telegram get real-time updates at every stage — thread created, agent working, PR opened, resolved.
Zero-Account Guest Comments
Stakeholders drop feedback on your live app without creating an account. Share a link, they comment. Zero friction, zero seat fees.
Scoped to Your View
Comments stay attached to the UI state where they were created. Feedback left inside a modal only appears when that modal is open — no stale pins on hidden content.
Role-Based Access
Admin, write, and read permissions per repository, with team-based access control and org-level multi-tenancy.
Your desk isn't the only place work happens.
Because the review lives on the web — not in a desktop file — the collaboration comes with you. Keep things moving from your phone.
Review & reply from your phone
Yocoolab is web-first, so the dashboard opens on any phone. Triage open threads, reply, and mark things resolved from the train, the couch, or the coffee line.
Stakeholders comment from a link
Share a guest link and anyone can leave feedback from their phone browser — no install, no account. Their note lands in your team's thread instantly.
Stay in the loop anywhere
Slack and Telegram pings reach you wherever you are — thread created, agent working, PR opened, resolved — so nothing waits for you to get back to your desk.

Button padding looks off on the pricing card — can we tighten it?
Click it. Your agent fixes it.
Click any element on your live app, leave a comment, and route it straight to your AI agent — Claude Code, Cursor, or your own, connected over MCP with full context. Watch the fix land in seconds.
