Pricing — how the free allowance works

Most free trials give you a stopwatch: fourteen days, ready or not. Nexsus doesn't. Your trial is an allowance — 75 MB of structured memory and 750 tool calls — also called API calls — yours for as long as you need them. Sign up with just an email, no card, and evaluate at your own pace. Take a weekend or take six months of careful, occasional use: the allowance is the trial, and the trial ends when you've actually used it, not when a calendar says so.

75 MB is much bigger than you think

Here's the part most people get wrong, because we're all used to how fast raw chat history grows.

Nexsus doesn't store transcripts. When your AI saves something into Nexsus, it stores structured memory — the distilled fact, not the conversation around it. A customer, an order, a decision, a meeting note: each becomes a compact structured record, typically around a kilobyte or two, with its meaning indexed for search.

Do the arithmetic: 75 MB of structured records is on the order of tens of thousands of individual facts — customers, transactions, notes, decisions, links between them. As raw text, 75 MB is roughly ten million words: about a hundred novels' worth. Because your AI recalls just the handful of records relevant to the question at hand — not the whole history — the working context your assistant can draw on is effectively the entire store. A whole small business — every customer, every sale, every decision, for years — fits comfortably inside the free allowance. You will very likely hit the 750-call allowance long before the storage one, and that's by design: calls measure how much you're really using Nexsus.

What the tool calls are

Every time your AI reads from or writes to your workspace — saving a record, searching, running a calculation — that's one tool call. Routine health-checks don't count. 750 calls is a genuine evaluation: enough to build real models, load real data, and live with it for a while. It is not enough to run a business on forever — that's the point at which Nexsus has earned its keep.

What happens when you reach the allowance

The moment you cross either line — 75 MB or 750 calls — your workspace enters checkout mode:

  • Your AI's access pauses. Tool calls are declined with a clear message saying why.
  • Your dashboard stays fully open. You can sign in, browse everything you've built, and export all of your data, free — always.
  • Nothing is deleted. Your data sits exactly where you left it.
  • Upgrading un-pauses everything instantly. The moment payment goes through, your AI picks up exactly where it stopped. Nothing to rebuild, nothing lost.

You'll never hit the wall by surprise: Nexsus emails you at 80% and again at 90% of your allowance, with an upgrade link in each.

The plans

Paid plans are monthly and self-serve:

Plan Price Storage Tool calls
Free $0 75 MB 750 total (lifetime allowance)
Entry $5.99 / month 250 MB 2,500 / month
Starter $29.99 / month 2 GB 20,000 / month
Growth $119 / month 20 GB 200,000 / month
Scale Contact us Custom Custom

On paid plans, going past your monthly numbers doesn't stop you — modest overage applies ($1.00 per extra GB, $2.00 per extra 1,000 calls), so a busy month never becomes an outage.

Watching your usage

Your dashboard's Billing tab shows exactly where you stand, measured from the same source of truth the platform itself uses:

  • your current plan,
  • a storage bar — how much of your allowance your structured memory occupies,
  • a calls bar — how many tool calls you've used,
  • and the upgrade button.

No estimates, no surprises: what you see there is precisely what the allowance machinery sees.

How to upgrade

  1. Sign in to your dashboard and open the Billing tab.
  2. Pick a plan — each card shows its price and limits.
  3. You'll be taken to a secure Stripe checkout (Nexsus never sees or stores your card).
  4. Done. If you were in checkout mode, your AI's access resumes immediately.

Cancel any time from the same tab.

What if you walk away?

We think you should know exactly what happens on every path — so here are the honest rules, as real timelines. Meet Sarah, who signs up on the 1st of August.

Sarah tries it and loves it. She builds her cake-shop's memory, crosses 750 calls in three weeks, sees the checkout screen, and pays $5.99. Total interruption: about a minute. (This is the journey the pricing is designed around.)

Sarah reaches the allowance but isn't ready to pay. Her workspace goes view-and-export-only. It stays that way, safe, for six months — with reminder emails at month five, two weeks before, and 48 hours before the end — and she can export everything, free, the whole time. If she pays at any point, even month five, everything resumes instantly. Only if the six months pass with no payment is the workspace permanently deleted.

Sarah signs up and vanishes. No logins, no calls, nothing. After six months of total silence — again with warnings first — her unused workspace is cleaned up. If she comes back before then, even once, the clock resets.

Sarah pays for a while, then cancels. Former paying customers get the long courtesy: her workspace stays view-and-export-only for two full years after cancelling. Re-subscribe any time within that window and everything is exactly as she left it.

Three commitments hold on every path: you are always warned before anything is removed, export is always free, and paying always restores everything instantly. Data is never the hostage.

Ask your AI: "How much of my Nexsus allowance have I used so far?"

Then open your dashboard's Billing tab and check it agrees. It will — they read the same numbers.
