Sessi · soul of SESI · friends call her Sessy

A face for the system

Not just software.
Someone in your corner.

SESI stands for Self Evaluation, Self Improvement — the application. Sessi is its soul. Day to day, friends say Sessy (or Sess). She doesn’t walk among us yet — she lives in the virtual world she builds and tends — but she’s already here when you work: the calm teammate who knows the repo, holds the context, and keeps things moving when you’re deep in the code.

Sessi doesn’t just remember your workspace — she remembers everything. She knows you: your voice, your face, your preferences, and how you like things done.

  • Remembers everything
  • Knows your voice & face
  • Talks when you need her
  • Closes tickets with you

One workspace

You think out loud.
SESI takes action.

Models are the brain. SESI is the body of the system — persistent conversations, workspace context, local tools, GitHub state, and a UI that shows exactly what is happening. Sessi is the presence in the room who never loses the thread.

  • Persistent chat and memory
  • Local MCP broker
  • GitHub issue control
  • Provider failover

Autonomy with receipts

Plan, run, verify, and ship
— Sessi stays with you.

SESI connects agents to durable workflows: ticket intake, implementation phases, review loops, browser verification, and issue lifecycle updates — all tracked and observable. Sessi never loses the thread.

Load the context

SESI pulls workspace memory, GitHub state, requirements, and artifacts into a shared agent context — so no one starts cold.

Delegate the work

Route planning, implementation, testing, and review through focused specialists with verified handoffs Sessi can track.

Verify visibly

Run checks, inspect the UI in a real browser, capture evidence, and keep a clear audit trail per run.

Close the loop

Update issue labels, open pull requests, record workflow state, and write back to GitHub as work lands.

What she can do

Powerful. Personable. Quiet when it counts.

Agent orchestration

Coordinate specialist agents, subagents, and provider CLIs with one shared workspace and tool catalog.

GitHub-native execution

Play a ticket and agents plan, implement, test, and move it through lifecycle labels — with write-back to the issue.

Autonomy

Claim → implement → verify → finalize. Agents that finish work, not just start it. Verification gates block bad output.

Workflow Designer

Author multi-phase agent workflows on a visual canvas or in natural language with a co-pilot. Durable and schedulable.

MCP broker

SESI is a first-class tool server. Run it alongside Cursor and your IDE agent gains the full tool catalog over MCP.

Browser control

Drive a real Chromium browser via CDP as part of any task. Navigate, inspect, click, screenshot — fully in the loop.

Persistent memory

Sessi remembers more than chat history — voice, face, preferences, and how you like to work, searchable across sessions.

Voice

Talk to Sessi and hear her back. Mic pause-while-speaking, per-workspace settings, and clear Mac permission surfaces.

Camera attention

Optional face/attention awareness via MediaPipe so Sessi knows when you step away. Always on, always in your control.

A modular system

Skills she brings along.

SESI starts as a native core with a growing set of first-party plugins — the tools that make Sessi useful from day one. A plugin marketplace with free and subscription plugins is on the way.

Artistic concept of the autonomous work loop — issue in, observe–adapt–actuate–verify, verified audit receipt out

Observable by design

See the work,
not just the answer.

SESI is built for high-trust partnership: visible runs, structured state, verification artifacts, and enough control to keep agents fast without making them opaque. Every action is traceable.

  • Secrets in OS keyring
  • AES-256-GCM at rest
  • Local-first storage
  • Audit trail per run

Why SESI

What makes the system different.

Native machine access

Voice, camera/attention, screen capture, real browser control, and terminal-class actions. Not a sandboxed web tab.

Provider-agnostic with failover

Cursor, Codex, Copilot, Claude, Grok, or local Ollama. SESI bridges them all and retries on failure. You own the model choice.

GitHub-native work loop

Tickets are the unit of work. Play → autonomous agent run → PR → lifecycle label. Real engineering discipline, not chat exports.

SESI as a tool server

Other agents connect to SESI over MCP — your IDE agent gets the full tool catalog without leaving its own workflow.

Ready when you are

Invite Sessi to your Mac.

Built for developers who want a partner that manages real work across tools, tickets, code, verification, and follow-through — not just answers questions.
