🔭 Projects

Speekl · speekl.com · speekl.ai

Two apps, one goal — getting people talking. speekl.com connects learners with human tutors for live lessons. speekl.ai is a personal AI tutor for real, voice-first conversations you can have any time, in 25+ languages.

`.tasks` · speekl-official/tasks

An open format for tracking agent work that outlives a single session. Tasks are markdown files under .tasks/, committed alongside the code they describe — no server, no account, no network. Dependencies say what's ready to start, and claims stop two agents grabbing the same task.

@speekl/tasks is the reference CLI. Spec · Quick start

npm i -g @speekl/tasks
