AI that knows what you know.
Without uploading any of it.
Every AI tool that wants to help with your actual work asks for the same thing: hand over your inbox, your files, your notes, your accounts — into their cloud, on their hardware, priced by the seat. Inseam is the open-source alternative. Your data stays where it lives. You run it. You own it. Built by the people who'll use it.
Today, you get two bad deals.
Pick your poison.
You want AI to actually help with your work — your real work, the kind that lives across your inbox, your drive, your notes, your tickets, your account with that one vendor your team somehow can't quit. The market currently offers two ways to do that. Neither is great.
- Each tool has its own login, its own permission grant, its own search box, its own quirks.
- The AI only ever sees what each search box hands back. Usually badly.
- A question that touches three tools means three half-answers. You stitch.
- The tool your team actually depends on? Probably not on the supported list. Wait in line.
- A second copy of every email, file, message — chopped up and stored on the vendor's hardware.
- Per-seat pricing that turns into real money the day you finish the trial.
- Permissions mean "is this person inside our workspace?" — useless for talking to customers, clients, vendors.
- Whatever the last crawl picked up. Edit a doc this morning, the AI is still answering yesterday's version.
The thing both options assume is that somebody else has to hold your data for you to get any value out of it. They don't. That assumption is what Inseam is for.
Things you can do
that aren't possible anywhere else.
Not "we do them better." We do them at all. Here's what becomes a normal Tuesday once your AI talks to your stuff through Inseam instead of through a SaaS that's holding it hostage.
The answer is somewhere across your email, a Slack DM, the contract draft in Drive, and a sticky in Notion. Today you get four search boxes. With Inseam, you get the answer — pulled from all of them, in one conversation, with the actual text in front of you.
A customer signs in. Your AI answers about their emails, their invoices, their account — and can't see anyone else's, ever. Today this is built bespoke per company, or — far more often — not built at all, and the chatbot stays a useless toy that can't reference anything customer-specific.
Edit a doc at 9:00. Ask the AI at 9:01. You get the 9:01 version. Cloud-RAG systems ingest on a schedule and your "intelligent assistant" is forever a few hours behind. It's one of the things people quietly hate about every existing tool.
Move from Gmail to Fastmail. Rotate an API key. Drop a SaaS you no longer pay for. The memory of who said what, what was where, when it happened — that stays. Everywhere else, pulling a connector either purges the data or leaves dead weight behind.
Internal CRM. Niche project tracker. The thing one team built and the rest of the company adopted. Inseam is open, with a plugin model designed so anyone — including an AI helping you — can add support in an afternoon. Your stack doesn't have to wait on someone else's roadmap.
Quietly on a laptop for a personal setup. Inside a team's own infrastructure for a small company. On a self-hosted server you already pay for. There's no vendor cloud you have to route through; there's no "enterprise edition" gating the feature you want. It's open source. You run it where it makes sense.
Curious how it actually works under the hood? The architecture page walks through it.
What you're getting.
What you're not.
We've been around long enough to know that the marketing page is usually where software lies to you. So instead of adjectives, here's the actual deal.
- Open source. The kind you can read, run, and fork.
- Yours to run — your machine, your server, your call.
- Built so the community extends it, not so we gate it.
- Real about who-sees-what. Per person, not per workspace.
- The layer between AI and your stuff. Not another place to put it.
- Something that gets out of the way once it's working.
- A cloud we host. A SaaS we bill you for.
- A second copy of your documents on our hardware.
- A chatbot. We don't ship the AI; we ship what the AI talks to.
- A list of supported tools you have to pray yours is on.
- An enterprise upsell gating the features that matter.
- A pivot waiting to happen — there's no investor to please.
Early. Honest about it.
This isn't a "coming soon" page from a stealth startup. It's a project being built in public, on nights and weekends and afternoons, by people who want this thing to exist for themselves. Some of it works today. Some of it is being designed right now. Some of it is on the list.
If you'd want to use this — or contribute to it, or push back on a design while it's
still on paper — now is the time to show up. The work happens in the open under
/architecture. Issues and pull requests are read. Cheerleading isn't
necessary; honest argument is welcome.
The community is small and the tent is open. If a tool you depend on isn't on the list, that's where your plugin ends up. If a design decision looks wrong, the design docs are still drafts — say so. The repo is the front door.
