Case Overview & Background

Denis Kirichenko spent years managing projects alongside his main job and found switching between planning tools on the move frustrating. Once AI became practical, he built a one-button prototype that turns a spoken sentence into a task. Voiset now serves entrepreneurs, field workers and people with ADHD who prefer to plan by voice.

How AI Is Used

AI is the product. Voiset is an AI planner that turns voice input into tasks, which he says saves up to 30 percent of planning time.

Step-by-Step Process

Step 01Solve your own planning pain

He built for people who capture ideas on the move.

Step 02Prototype with one button

The first version turned one spoken sentence into a task.

Step 03Test with small businesses

He tested with small business owners who run operations in messengers.

Customer Acquisition & Distribution

Testing with small business owners and listening closely to customers, by his account.

Limitations, Risks & Failure Modes

What may not apply to you, and what could go wrong:

  • The figures are self-reported and were not independently checked
  • Large task apps can add similar voice AI features

Key Takeaways

  • Voice plus AI can simplify a crowded app category
  • A clear one-click promise is easy to explain
