What Yachiyo can do
The whole feature set fits on a handful of notes. Drag them around.
Reply Branching
Conversations form a tree. Explore different tones without losing the other paths.
Skills are just Markdown
Drop a SKILL.md into your workspace. No runtime. No API surface. It just works.
Multi-Provider Runtime
Claude today, Gemini tomorrow, your own model next week. Switch per-message.
Channel Multiplexing
One local instance for Telegram, Discord, and QQ — shared context, shared memory.
Scheduled Runs
Set one-off or cron tasks, then let Yachiyo run them while you focus elsewhere.
Coding Agent Dispatch
Hand implementation work to a subagent, then bring the result back in-thread.
Local-First Storage
Everything stays in SQLite under ~/.yachiyo/. No cloud. No telemetry.
Browser-Backed Research
Search live sessions, read pages into Markdown, and keep what matters.
Why Yachiyo?
Because your assistant should be yours.
Yours, not a platform
Most AI clients want to become ecosystems. Yachiyo respects your privacy and gets out of your way.
No MCP. No marketplace.
A skill is one Markdown file you can read, edit, and delete. That is the entire extension surface.
No telemetry
Your data never leaves your machine unless you send it. Local SQLite, local memory, local soul.
A living persona
SOUL.md and USER.md shape every interaction. She remembers, adapts, and grows alongside you.
