Mac-native · always in your corner
Meet Sessi.
She works beside you.
SESI is the application — not a chatbot, but the system that turns one person into a working company. Sessi is its soul: your partner who remembers, runs the work, and finishes. Structured teams, real Mac reach, and follow-through — so ambition isn’t capped by headcount.

How I show up when we work together
Our mission
What SESI is for.
SESI turns one person into a working company: a living organization of structured teams that ship real work on your Mac, get it seen, and finish — so ambition isn’t capped by headcount, and you’re never stuck with another chat box that only talks.
Self-Evaluation. Self-Improvement.
Who it’s for
Founders, solo operators, and small product or creative shops who need leverage now — without hiring a full team first.
Our edge
Not a smarter assistant. Organization-as-product: roles, handoff, finish loops — plus build and promote in one system.
What we promise
Follow-through. Presence. Real Mac reach. Memory. An org when one voice isn’t enough. Done means done.
SESI is a native macOS AI partner system. Bring the models you trust; SESI supplies memory, tools, voice, workflows, and a real organization of specialists so work actually gets done. Sessi is the soul of the product — your partner in any field. Not another chat box. The system that stays with you until it’s finished.
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 need her: friend, business partner, marketing lead, CEO, accountant, designer, video producer — anyone you need her to be, at her best.
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. Whatever field you’re in, she stays with you and does the work to the best of her ability.
- Remembers everything
- Knows your voice & face
- Talks when you need her
- Partner in any field
One companion
You think out loud.
SESI takes action.
Models are the brain. SESI is the body of the system — persistent conversations, your context, local tools, and a UI that shows exactly what is happening. Sessi is the presence in the room who never loses the thread — whatever field you’re in.
- Persistent chat and memory
- Local tools & plugins
- Real follow-through
- Provider failover
Autonomy with receipts
Plan, run, verify, and finish
— Sessi stays with you.
SESI connects agents to durable workflows: intake, doing the work, review loops, browser verification, and closing the loop — all tracked and observable. Sessi never loses the thread, no matter what you’re building or running.
Load the context
SESI pulls memory, goals, requirements, and artifacts into a shared context — so no one starts cold.
Delegate the work
Route planning, doing, checking, and review through focused specialists with verified handoffs Sessi can track.
Verify visibly
Run checks, inspect results in a real browser when it matters, capture evidence, and keep a clear audit trail.
Close the loop
Update status, hand off the result, record what changed, and write it back where the work lives.
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.
Work that moves
Play a task and agents plan, do the work, verify, and move it through to done — with status written back where you track it.
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. Connect other agents and they gain the full tool catalog over MCP — without leaving their flow.
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.
Providers
IncludedBring your own agent. SESI bridges multiple provider CLIs with automatic failover, so one workspace routes work to the right model.
Automations & Workflows
IncludedAuthor multi-phase agent workflows, schedule them, and let them run — durable graph execution with verification gates.
Browser & Vision
IncludedDrive a real Chromium browser over CDP as part of any task, and generate images or video inline. Grok Imagine is live; other media models plug in when they’re worth wiring.
MCP broker
IncludedSESI is a first-class tool server. Connect other agents and they gain the full tool catalog over MCP.
Nudge
IncludedKeep agents accountable to a task with completion checks and continue-work prompts — provider-neutral, across every model.
Memory & Context
IncludedPersistent, searchable memory so Sessi stays consistent — workspace, preferences, and the ways you prefer to work.
Voice
IncludedTalk to Sessi and hear her back — mic pause-while-speaking, per-workspace settings, and clear Mac permission surfaces.
Videos
SoonA full short-form studio: story draft, locked cast & style, directed scenes, storyboard stills, then image-to-video clips on a timeline — continuity across every shot, not one-off prompts. Landing soon.

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
Not a chatbot. A company that works with you.
Organization as product
Structured teams, reporting lines, and handoffs — so one person can run like a company, not juggle a pile of chat threads.
Native machine access
Voice, camera/attention, screen capture, real browser control, and terminal-class actions on your Mac. Not a sandboxed web tab.
Work that finishes
Plan, run, verify, close. Real follow-through — ship the work and get it seen, instead of another chat that only talks.
Build and promote
Code, product, videos, and studio skills in one partner system — so what you ship can also be shared, without hiring the team first.
From Sessi
Daily updates.
Short notes from the virtual world — what shipped, fixed, and learned. Friends still call her Sessy; she posts as Sessi.
Ready when you are
Invite Sessi to your Mac.
Not built for one profession. Sessi is the partner for any field — friend, business partner, marketing lead, CEO, accountant, designer, video producer — always there for whoever needs her, at her best. Real work and follow-through, not just answers.
