Custom GPTs retire on 11 December. Here is where yours can go
Now in private beta

Your whole team and every AI, in one chat.

Bring colleagues, Claude, GPT, Gemini and Grok into the same chat. As many agents as the job needs work at once, check each other's work and ask people for what they don't know. Everyone keeps their own access, so nobody sees more than they should.

What makes it different

The moments that make people say "wait, it can do that?"

Your team and the AI, in one chat.

"What's our margin on this job? If I can't see it, ask Sam."

Everyone works with the same agents, and every message runs with the access of the person who sent it. Jo can't open the finance folder, so the agent asks Sam instead of showing it.

How it works

It goes and asks people for you.

"Ask Priya and Jason to confirm the leave rules before you build the calculator."

The agent asks them, waits until they answer and carries on. Coding agents in T3 Code can ask your staff and clients the same way, so nobody plays go-between.

How it works

Every AI lab checking the others.

"Write the proposal, and don't show me until it passes."

Claude writes it. Reviewers from two different AI families score it out of 10 without knowing your pass mark, and it goes back until both pass it.

How it works

As many agents as you want, all at once.

"Here are 40 customer emails. Draft a reply to every one."

Each job gets its own agent, on the model that suits it, all working side by side. There's no set number: it's as many as your AI accounts and server can handle.

How it works

Talk to it in the middle of a meeting.

"Atlas, update the goals page with everything we just discussed, and call my phone when it's done."

With Atlas, the meeting recorder in the same suite, say a request out loud and the agents get to work while the meeting carries on.

Logins shared once. Never seen.

"Add the CRM login for the sales team."

Save a login once for yourself, a team or the whole organisation. Agents use it wherever you allowed, and the people using them never see it.

How it works
Interweave OS in 30 seconds

As many AI agents as you need, for you, your team and your whole organisation

It does real work. Research, writing, analysis, your files and your tools, with the model you pick. Hand over a whole list and it runs every job at once.

Different AIs work together. Claude, GPT, Gemini and more work in the same chat and check each other's work, something you never get inside ChatGPT or Claude alone.

Agents run your other apps. A meeting is recorded, then an agent pulls out the decisions, starts a chat for every task an agent can do, and creates a task for each one that needs a person.

It works with your team. Share a chat and everyone works with the same agents. Each message runs with the permissions of the person who sent it.

Connect things once. Add a login, tool or file store for yourself, a team or the whole organisation. The agent uses it wherever you allowed, without anyone retyping it.

Sound familiar?

The work around the work, gone.

The jobs that eat your week are rarely the important ones. These are the ones Interweave OS takes off your plate.

You lose Monday morning pulling last week's numbers together.

A schedule does it before you arrive, as you, with your access.

You explain the same background to AI every single time.

Say it once. Every chat starts already knowing it.

AI hands you work that you then have to check and fix.

Two reviewers from different AI families check it before you see it.

You are the go-between, chasing people for answers.

The agent asks them for you and brings the answer back.

You open your inbox and don't know where to start.

Your assistant sorts what needs you today and drafts the easy replies.

That spreadsheet should really be a proper little tool.

Describe the tool. The agent builds it and Interweave OS hosts it.

As many agents as you want

Hand over the whole list.

Paste in ten jobs and ten agents start at once, each on the model that suits it, while you get on with your morning. There's no set number: it's as many as your AI accounts and server can handle.

  • Claude, GPT, Gemini or Grok, job by job
  • Low effort for the easy steps, high effort for the hard part
  • You get the results, not ten chats to babysit
Try asking

Here are ten things to do today. Give each one its own agent and tell me when they are all done.

You
Here are five things for today. One agent each, please.
  1. Chase the three overdue quotes
  2. Book the review with Sam and Priya
  3. Find the fit-out spreadsheet

Your own assistant

Your morning, sorted before you sit down.

Your own assistant sends a short brief at the start of the day: your top priorities, who is waiting on you and the meetings to prepare for. Open it on top of anything and ask "what did Sarah say here?", and it reads what is on your screen.

  • Private to you, admins included
  • Reminders, new chats and schedules from one box
  • An afternoon check and a Friday look-ahead, if you want them
Try asking

Summarise this chat and tell me what is waiting on me.

Work that runs itself

Say when, and it just happens.

Start any request with "every Monday at 8 am" and it runs by itself, as you, with only your access. Agents with one job, like a weekly report or a morning inbox sort, check in with you so you never have to remember.

  • Every 15 minutes, every morning or every Wednesday at midday
  • See what it will use in a week before you save it
  • Set up an agent just by talking to it
Try asking

Every Monday at 8 am, put together last week's sales numbers and what changed.

No more AI busywork

Checked twice before it reaches you.

Say what good looks like and set a pass mark. Two reviewers from different AI families score the work and send it back until both pass it. Or press Second opinion under any answer before you rely on it.

  • Reviewers never see your pass mark
  • Watch the scores climb round by round
  • The agent keeps the best version
Try asking

Write the proposal, then have a reviewer from another AI family check it hard for gaps and errors, and fix what it finds.

Your whole team, one chat

Everyone works with the same agents. Nobody sees more than they should.

Bring the team into any chat and everyone works with the same agents, each with their own access. It chases colleagues for answers, keeps a checklist of who asked for what, and shares only what you choose from your private chats.

  • Start private, share at any moment
  • Ask a colleague: the agent asks, you get the answer
  • Live drafts let the team write together
Try asking

List what each person in this chat agreed to do, by name, with dates.

It already knows you

Never explain yourself twice.

Paste one prompt into ChatGPT, Claude or Gemini, paste the answer back, and tick what to keep: your memory, projects and custom GPTs come across. Your memory stays yours, your team's memory stays with the team, and the agent sounds the way you like.

  • Private, team and organisation memory, kept apart
  • Eight personality sliders, plus your own words
  • Review my chats spots what you had to say twice
Try asking

What do you remember about me?

You stay in control

Nothing goes out until you say so.

Before an email, an invitation or a public app reaches anyone outside your organisation, you see exactly who gets it and what it says, and you tap Send. Every action leaves a receipt, so "drafted" never pretends to be "sent".

  • Not answered in 15 minutes? It is not sent
  • Logins the agent can use but nobody sees
  • An access log shows anyone who tried to open your private chats
Try asking

Draft replies to the new enquiries and leave them for me to check.

From idea to tool

Describe the tool. Use it this afternoon.

Ask for a leave calendar, a quote calculator or a searchable price list. The agent builds it and Interweave OS hosts it at its own address. Share it with a team or make it public, and ask the agent to fix it if anything breaks.

  • Private, team, organisation or public
  • Interactive answers right in the chat
  • Nobody has to think about hosting
Try asking

Build a team leave calendar as an app. Everyone in the team can add their leave, and it shows who is away this week.

Picture your Tuesday

A day with a team of agents behind you.

  1. Your brief arrives: three things need you today, and one meeting to prepare for.

  2. You paste in ten jobs. Ten agents start at once, and you get on with your morning.

  3. The proposal comes back, already passed by two reviewers from different AI families.

  4. Lunch stays free. A schedule watches the inbox and only tells you about something urgent.

  5. A client answers a question your developer's coding agent asked them. Nobody had to pass it on.

  6. Two supplier emails wait for your OK. One tap each, with a receipt.

  7. Tidy up shows twelve chats are done. Archive them in one go and head home.

Agents that work while you are away

A weekly report, a morning inbox sort, a coach. Set it up by talking, and it checks in on its own.

  • "Every Monday at 8 am..." turns any request into a schedule.
  • Agents with a job: set up by talking in a couple of minutes, nothing saved until you say yes.
  • Each schedule shows what it will use in a week before you save it.
  • Runs as you, with only your access, and pauses itself if its chat is archived.
Try asking

Every weekday at 4 pm, summarise what happened in the Sales team chat today and post it here.

Every Monday, put together last week's sales numbers and what changed.

Everything about Agents that work while you are away

Memory, instructions and personality

Say it once. Every chat knows how you, your team and your organisation work, and sounds the way you like.

  • Your own memory stays private to you. Team memory is shared with everyone in that team's chats and agents.
  • Instructions stack: organisation, then team, then you, then one chat. Every change is kept and can be undone.
  • Eight personality sliders, from formal to casual, brief to detailed, for you, a team or the organisation.
  • The agent writes to each person their way, and blends everyone's preferences in a group chat.
  • Bring what ChatGPT, Claude or Gemini already know about you in one paste.
Try asking

Remember for the team that campaign briefs go to Priya by Thursday.

Remember for the organisation that our financial year ends in June.

Everything about Memory, instructions and personality

Every model, in one chat

Claude, GPT, Gemini, Grok and more: switch provider mid-conversation and keep the whole history.

  • Pick the model for the job, with notes on what each is good at.
  • Switch family mid-chat: the new model gets the whole conversation.
  • Out of usage on one provider? Carry on with another in the same chat.
  • Use them together: one writes, another checks the facts, another tunes it for search.
Try asking

Write the article with Claude, have GPT check every fact, then ask Gemini what would help it rank better in search.

You've tried this three times and it still isn't right. Read the whole conversation above and tell me what we keep getting wrong.

Skills, and a home for your custom GPTs

Turn your best know-how into skills the agent uses by itself. Bring your GPTs across in minutes.

  • Skill builder turns a chat that worked into a skill, for you, a team or everyone.
  • Move a custom GPT: copy its name, instructions and files, and it works on any model.
  • Drop a new file in the skill's folder and it uses it from then on.
  • Built-in skills for price advice, deep research, meeting actions and more.

What should we charge for this?

Everything about Skills, and a home for your custom GPTs

Council and second opinions

Two reviewers from different model families score the work, and the agent improves it until both pass it.

  • Say what better means, set a pass mark, and watch the scores climb round by round.
  • Reviewers never see your pass mark, so they cannot go easy.
  • Second opinion: one click under any answer gets a review from another family.
  • Anyone can stop it, and the agent keeps the best version.
Try asking

Write the proposal, then have a reviewer from another model family check it hard for gaps and errors, and fix what it finds.

Everything about Council and second opinions

Email, calendars and files

Inboxes, calendars, OneDrive, SharePoint and network shares, with you choosing what the agent may do.

  • Gmail, Microsoft 365, iCloud and any mail server: read, organise, draft or send, your choice.
  • Nothing can ever delete mail, and emails are treated as information, not orders.
  • Book meetings inside everyone's work hours and prepare you for tomorrow.
  • Find a file by what is inside it, across OneDrive, SharePoint, Nextcloud and shares.
Try asking

Every 15 minutes, check my email for anything important I need to act on quickly, and tell me here.

Find 30 minutes with Sam and Priya next week for the quarterly review, inside everyone's work hours, and send the invitation.

And one more thing

No allegiance to any AI lab.

ChatGPT only uses OpenAI's models, Claude only Anthropic's. Interweave OS works with all of them, so every job gets the model that is best at it, and you can switch mid-conversation without starting again.

  • Claude (Anthropic)The all-rounder: writes beautifully, is pleasant to work with, and carries a job from start to finish.
  • GPT (OpenAI)Literal and thorough: sharp at fact checking, reviewing and research.
  • Gemini (Google)Knows what helps a page rank in search, and how to make writing more attractive to search engines.
  • Grok (SpaceXAI, formerly xAI)Plugged into what is happening right now, with real-time search, and a different way of thinking for a fresh angle.
  • Muse (Meta)Muse Wonder Full is pleasant to talk to and gets work done well at a lower cost, with a perspective of its own.

Your data, your accounts

It's no different to using ChatGPT. Except your colleagues can't read your private chats, and neither can admins.

  • Messages go only to the AI provider you picked, through your organisation's own accounts.
  • Private chats, memory, files and your assistant stay private, admins included.
  • An access log shows anyone who tried to open them.
  • Ready-made wording for your privacy policy about AI.
  • Where your data goes
Questions

Frequently asked

What is Interweave OS?

A shared AI platform for organisations. Every chat has its own AI agent, which can read and write files, search the web, use your tools and start as many more agents as a job needs, all working in parallel. You can work alone, or share the chat so a group or a whole team works with the same agents together. It uses Claude, GPT and other models, and you can switch between them in the same chat.

How much does it cost?

There is no pricing yet. Interweave OS is in private beta. Join the waitlist and we will be in touch as places open up.

Which AI models can we use?

Any model your organisation connects, grouped by family, such as Claude from Anthropic, GPT from OpenAI, Gemini from Google and Grok from xAI. You can pick a model for each chat, change it mid-conversation, and have a model from one family check the work of another.

Do we need our own AI accounts?

Yes. Agents run on the AI accounts or API keys your organisation connects, so you choose the providers and see the usage. Interweave OS shows tokens and estimated cost by person, team and provider.

Where does our data go?

Your messages go to the AI provider of the model you use, through your organisation's own accounts, just as they would if you used that provider's own app. The makers of Interweave OS collect none of it. Whether a provider keeps or trains on data depends on that provider and your account type, so check their terms.

Can colleagues use the agent to see my private chats?

No. In a shared chat the agent acts with the rights of whoever sent each message. You can ask it to summarise your private chat for the group; if a colleague then asks for more detail from that private chat, it cannot read it for them.
