An “AI employee” service from Kuse Inc. in the United States. Instead of being prompted for every task like a chatbot, Junior joins your Slack or Microsoft Teams workspace as a coworker and takes on role-based work across sales, marketing, and operations. It has its own email address, connects to more than 3,000 apps such as CRMs and ad accounts, and works while remembering your organization’s past exchanges and decisions. The official site describes it as starting on day one and getting smarter every week.
Key Features
- Lives in Slack / Microsoft Teams: There is no new dashboard to learn. Junior joins your existing chat workspace as a member. You can mention it with a request, and it also moves scheduled work forward without being told
- Prebuilt role templates: Eleven roles are offered officially, including AI Sales Rep, AI Executive Assistant, AI Media Buyer, AI Customer Support Rep, AI Recruiting Coordinator, and AI Finance Assistant. You pick the one closest to the job you want covered
- Connects to 3,000+ apps: External services are reached through Pipedream. That covers work spanning multiple tools ─ updating CRM records, monitoring campaigns and reallocating budget, organizing invoices, screening candidates and coordinating interviews
- Has its own inbox: Junior receives and replies from its own email address, answering inquiries and scheduling meetings. Cases it cannot judge are meant to be escalated to a human
- Remembers organizational context: Conversations, documents, and past decisions accumulate and feed into later work, so you re-explain background less often
- Runs around the clock: Because it works 24/7, teams with overseas offices or customers in other time zones spend less time waiting
Pricing
| Plan | Monthly price | What you get |

The Standard plan works by setting how much budget your Junior gets each month. It can be changed at any time from the dashboard with prorated billing. The site also mentions SOC 2 Type II and availability through AWS Marketplace.

Pros & Cons
✅ Pros
- It drops into your existing Slack / Teams, so there is little overhead in learning a new tool or handing out accounts
- Role templates mean you do not have to design “what to delegate and how” from scratch
- With 3,000+ app integrations, routine work that spans several tools can be handed over as a whole
- Budget is set in $100 increments, making it easy to start small and expand as results come in
- Because it remembers organizational context, instructions get shorter the more you use it
⚠️ Cons
- Autonomy cuts both ways: without careful permission design and review, mis-sent messages or wrong record updates are a real risk
- Even on Standard, a budget large enough for production use adds up, and the free tier alone is not enough to judge by
- Since external integrations are the premise, you need internal agreement on how far it may reach into sensitive data such as CRM and email
- The free trial limits available models and concurrent sessions, so production-level load is hard to simulate
- Public information about operating it in Japanese-language environments is limited, so validate your own use case before rolling out

Who Is It For
- Startups where hiring cannot keep up and routine sales or operations work is piling up
- Teams where Slack or Teams is the center of work, so bringing tasks there keeps things moving
- Marketing and sales groups that want to cut manual work spanning CRM, ads, email, and calendars
- Leaders who want to test AI agents on real work with a small budget first and expand based on results
- Organizations with customers or partners in other time zones that want to shorten response delays
Summary
Junior commits fully to treating AI not as a handy chat partner but as a coworker with a job title. Living in Slack or Teams, holding its own email address, connecting to 3,000+ apps, and retaining organizational context, it is built to move work forward rather than wait for instructions. That same autonomy, however, depends entirely on how you design permissions and review. A practical path is to start with the free trial on a single role, decide where human confirmation belongs, and widen the scope from there.
