Run your business on agents.
Tasklet lets you delegate real work to AI agents. Connect your tools, automate workflows 24x7, and share agents and context across your team. No developer needed.
Get your whole company using AI, not just one or two power users. Tasklet can handle every job function: • Sales: enrich new leads, update the CRM, and draft the reply • Marketing: turn Mondays industry news into LinkedIn posts • Operations: every Zendesk ticket gets a matching Linear issue • Finance: match Stripe payouts to QuickBooks and flag mismatches • Executive and admin: a prep brief in Slack before every meeting
Connect to everything. Tasklet connects to thousands of SaaS tools, MCP servers, or any API, even the private ones your company built. No API? Your agent has a browser, so it can work through vendor portals and internal apps the way a person would.
Automate work 24x7. Agents take ongoing responsibility for entire business processes and run on a schedule or on business events. You decide what they can do on their own and what needs a human first.
Share what works. Share agents so business-critical workflows keep moving when someone is out of office. Share connections so the team builds on your tools without sharing the keys. Share skills, files, and memory so everyone levels up together.
Need an internal app? Ask for it. Tasklet turns a prompt into live software, wired to your real data and tools, and shareable with your team.
Pay for work, not seats. Add unlimited team members for free and pay only for usage, with real-time spend analytics and credit caps per agent. Use the best models from Anthropic, OpenAI, Google, and open source, all in one place.
Everything IT needs to say yes: granular access controls, guardrails on what agents can touch, isolated cloud environments per agent, and full visibility into usage and spend. SOC 2 compliant.
