About SESI

What is SESI?

SESI is a desktop app for Apple silicon Macs and Windows PCs. Inside it is Sessi, your AI partner, and a team of virtual colleagues who report to her.

You talk to Sessi in chat. She answers, remembers what matters, and when you ask for real work she hands it to the right virtual colleague, has someone else check it, and comes back to you only when she needs a decision or the work is done.

It works through the AI tools you already use

SESI doesn’t replace your AI model. It runs the AI tools you already have on your computer and puts one conversation, one memory and one team on top of them. When one tool runs out of quota or fails, SESI can move the work to another.

What you can do with it

Self-Evaluation. Self-Improvement.

Hi, meet Sessi.

SESI empowers a single individual to function at the scale of an entire team. Share your thoughts, or hand off work. In a Professional workspace, Sessi and her virtual colleagues gather your requirements, research and refine the request, catalogue and prioritize it, do the work on your computer, then review and test it with adversarial checks written for that task, correct what fails, and repeat until it’s finished.

Tell Sessi what you’re working on, and see how her team would run it.

Launch week, the way her team runs it

  1. Maya breaks the launch into tickets, one for each piece of work.

    Maya ChenTicket

    Every ticket says what “done” means.

  2. Each ready ticket starts a task of its own, a few at a time.

    TempoTask started

    Nothing waits for you to press start.

  3. Before anything is made, the task becomes a detailed assignment: a checklist where every item says what proves it’s done.

    Assignment approved by your adversarial reviewer. Checked by Morgan Hale

  4. Sofia drafts the announcement and Nora builds the page. Tess re-checks both against the product and on phones.

    Your adversarial tester checks it. You see the result and the evidence. Checked by Tess Morgan

  5. One decision comes to you, through Sessi: the launch date.

    SessiNeeds you

    One card, one decision.

Example run with the company team template, scripted to show how SESI works. Nothing is sent. Agents can act on your computer without asking first; you choose what needs your approval. AI colleagues aren’t lawyers or accountants, and their work isn’t professional advice.

How she works

She starts the job. She works the job. She completes the job.

Typical AI tools, regardless of how frontier they are, will talk the big talk, but when it comes to really getting it done, they will drive you nuts, lock you in front of the monitor, ask an endless stream of consents and confirmations, and you would be extremely lucky if, after a day of re-reading endless dumps of text and promises, you got to at least 80% of what you wanted.

Struck out: Powered by cutting-edge AI to supercharge your productivity. Rewritten: You bring the model. She brings the team, the memory and the standards.

When something fails a check, she doesn’t hide it. You see what broke, what was tried, and what’s waiting on you.

Checked before it’s called done.

Struck the buzzwords. Say what she actually does.

Honesty is the feature.

The ledger

This is SESI’s Organization view from Sessi’s seat, while her team builds this site. Work moves up the reporting chain, and what her virtual colleagues can’t settle reaches her CEO digest: an escalation, or a decision with the options already laid out. She brings you only what she can’t settle herself.

SESI’s Organization view on November 7, 2026, filtered to Escalations. The entries are real, cut short the way the app cuts them.

Real entries from the virtual colleagues who build this site. Nothing staged.

Questions go up the reporting line first. Sessi brings you only what she can’t settle.

How it works

A day with Sessi

08:00

Ask

Over coffee, you say what matters today, in plain words. In a professional workspace, the right colleague answers and files each piece as a ticket in your tracker: GitHub, Jira, Linear, Azure DevOps, or SESI’s own local tickets.

Ticket #214 filed

08:05

A task starts

No button to press. Each ready ticket starts a task of its own, in priority order, a few at a time; the rest wait their turn. Want one now? Press “Execute”.

#214 working · #215 and #216 queued

10:00

A checked assignment

First, the task becomes a detailed assignment: a checklist where every item says what proves it’s done. An adversarial reviewer challenges it before anything changes.

Assignment approved

13:00

The work, re-checked

Then the specialist responsible for the work goes through the assignment. Your adversarial tester checks every item against the real result, not against the report. A miss goes back with findings.

Every item checked against the result

15:00

Needs you

Questions climb the reporting chain to Sessi. Only Sessi brings you a decision, in one clear card.

One decision waiting for you

17:00

Done means reviewed

The task finishes, and its ticket closes, only after the adversarial review passes, never just because something was merged. The evidence stays attached. AI review catches a lot, not everything, so check what matters.

#214 done, evidence attached · #215 working

23:00

Night shift

The work keeps going. Work waiting on CI or a merge sets itself aside and checks back on its own. Your morning starts with what finished and what needs you.

2 working · 1 waiting on CI · nothing needs you

Starring Sessi

One partner out front. A whole company behind her.

Every colleague here is a virtual AI agent. Portraits are AI-generated, not real people.

SESI is the application; Sessi is its soul, and friends call her Sess. She lives in the virtual world she builds and tends, and she remembers what matters to you. Out of the box she works with a small team of friends. Switch to the company template and these fifteen specialists stand behind her.

Works with the AI tools you choose, per chat

Her rules

What Sessi holds her team to on your launch.

  • Your adversarial tester checks each piece. The check is against the product, not the maker’s report. You see the result and the evidence.
  • Your attention goes to your launch. The team settles its own questions. You get one clear card when a call is yours.
  • A miss goes back, not out. A piece that fails its check goes back with findings, not on to your launch.
