Features

Everything the work needs.

Thirdpen reads your files and apps, runs real code, drives a browser and hands back finished work. Here is what it does, and how you stay in charge of it.

Get started How we keep it safe

01 · Finished work

The deck, not advice about the deck.

Thirdpen publishes real files into the thread: decks, spreadsheets, documents, PDFs and Markdown. Ask for a change and you get version two, with the first one kept. Open any of them in Google Docs, Sheets or Slides, or save a copy to Drive.

  • PowerPoint, Excel, Word, PDF and Markdown
  • Every version kept
  • Open in Google Docs, Sheets and Slides

02 · Your apps

Work inside the apps you already use.

Connect Gmail, Slack, Drive, Notion, GitHub, HubSpot and 124 more. For each app you choose whether an agent may only read, may make changes, or may also delete. Anything that sends, posts or deletes waits on a card until you press Allow.

  • 130 work apps
  • Read, change and delete, switched separately
  • A card before every send
Send Dana the follow-up.

Here’s the draft. It goes out once you allow it.

Sales wants to send email in Gmail

This runs in your connected Gmail account. Nothing happens until you allow it.

Hi Dana, congrats on the Reno opening. Here’s how the first month would look.

03 · Computer and browser

Its own computer for every piece of work.

Each thread gets a private Linux machine with a browser. Thirdpen writes and runs real code for the numbers, reads the web and clicks through sites the way you would. When a page needs your password, a passkey or a CAPTCHA, it stops and hands the browser to you.

  • Real code for the maths, not guesses
  • A browser you can watch, live
  • You take over for sign-ins and payments

04 · Routines

It shows up every morning.

Turn any work you repeat into a routine: every day, every weekday, or on the days you pick. Each run happens at the time you set, in your timezone, and emails you when the work is ready.

  • Daily, weekday or weekly
  • Runs in your timezone
  • An email when the work is ready

05 · Memory

Say it once. It remembers.

What you tell Thirdpen in one chat is there in the next. What it learns about you is kept apart from what each agent knows about its work, and an incognito thread is never remembered at all.

  • Carries context from chat to chat
  • Kept separately for you and for each agent
  • Incognito threads are never remembered

Exam dates Sep 14

My BIO 110 exam is December 12. It covers chapters 1 to 9.

Got it.

This week Sep 28

What should I study this week?

Chapters 7 to 9. They’re on your December 12 exam and you haven’t covered them yet.

06 · Skills

Tell it how you work.

Save a procedure once as a SKILL.md: your brand voice, the invoice check, the weekly update. Thirdpen reads only a skill’s name until the work calls for it, then follows the steps. Skills use the open Agent Skills format, so they stay yours.

  • Standard SKILL.md files
  • Loaded only when the work needs it
  • Admins choose the skills the team shares

  • Brand voice

    Use when writing for customers.

  • Invoice check

    Use when reconciling invoices.

  • Weekly update

    Use when writing weekly updates.

    weekly-update/SKILL.md

    1. 1. Lead with the big win.
    2. 2. Three short bullets.
    3. 3. End with what’s next.

07 · Apps

Ask for a tool. Get a live app.

When the work needs a tool rather than a file, an agent builds a small app with its own data, screen and buttons. Everyone in its chat can open it; share it with more people or the whole workspace, and their agents can act in it too. It starts with only what you asked for, and grows when you ask.

  • Built from one message
  • Shared with your team in one click
  • People and agents both press the buttons
Make a deal desk where reps request discounts and I approve them.

Done. Reps add a request, you approve it, and every agent can see what was agreed.

Workspace

Built for a team.

One workspace holds your agents and the finished work. Each person’s threads stay theirs, and anyone can share one when the team needs to pick it up.

  • An agent for each kind of work

    Give sales, support and the weekly report an agent each. Every agent has its own description, memory and routines.

  • One workspace for the team

    Invite people by email. Each thread is private to whoever started it until they share it with a colleague or the whole workspace.

  • Incognito when you need it

    An incognito thread is visible only to you. It never appears in anyone’s list and is never remembered.

08 · You stay in charge

You decide how much it does alone.

Pick a mode, and change it whenever you like. Reading your own files and working in its own computer never needs a card. Changes to the outside world do.

  1. 01

    Read only

    External apps can be read, never written to.

  2. 02

    Ask

    Every change to a connected app waits for your approval.

  3. 03 Default

    Auto

    Edits run; sending, posting and deleting wait for approval.

  4. 04

    Auto-all

    Every external action runs without asking.

Routines run with nobody watching, so the tools that create or change agents, skills and apps are switched off for them. More on security
