Off-Nadir Delta
Quick answer — what Off-Nadir Delta is

Off-Nadir Delta is an AI-ready OSINT and satellite GEOINT platform that decides what is worth observing. Disasters, conflict, environmental change, and infrastructure failures unfold worldwide every day, but the signals are scattered across news, open data, and satellite imagery — and reading them takes expertise and time. Off-Nadir Delta combines an AI analyst, maps, satellite data, and open sources to explore, visualize, and prioritize geographic events, and to answer the questions that precede any imagery spend: can a satellite settle this, is free Sentinel-class data enough or does it need commercial tasking, and when can the place next be imaged. Factual claims link to their sources, judgments are labelled as judgments rather than facts, and each brief reports its own citation coverage — naming any claim that lacks a source — instead of producing an assessment anyway. There are three ways to look, distinguished by scope: Delta Watchfloor (everywhere, today — today's prioritized picture of global risk, so you know where to look now; the latest events up to the previous day are free to browse, and the real-time view of today is on paid plans), Delta Map (one place, right now — verify an event from space with Sentinel-1 C-band SAR, NISAR L-band SAR, Sentinel-2 optical, VIIRS nighttime lights, and NASA FIRMS active fires, no GIS software required), and Delta Watchlist (what you care about, over time — fix an area or follow an event, pick what to count such as ships alongside a berth, a burn index or a water index, and every new Sentinel-1, Sentinel-2, NISAR or VIIRS acquisition over it is measured automatically, with unusual readings flagged against the history). And two ways to be told: Delta Agent (an AI analyst that explains what happened and why it matters, and recommends which satellite sensor and area to image next) and Delta Reports (a written daily assessment with Key Judgments, calibrated confidence, and an outlook). Built for OSINT, geopolitical-risk, and satellite-intelligence analysts, and for developers integrating live signals and briefs through the API and MCP. Also applicable to emergency management, media, enterprise-risk, and research workflows. No intelligence background required. Free tier available. Off-Nadir Delta has a Free plan, two individual plans (Starter and Pro) and team plans. The plan decides what you can open; tokens pay for the work you run. Tokens are deducted by operation. Tile requests, imagery searches, assessments, monitoring runs, and Analyst questions have different costs. Estimated and maximum costs are shown before execution.

Start free. Pay for what Free can't open.

Free already covers the Watchfloor — what happened in the world, on a map, up to yesterday — a Watchlist that emails you when something changes, the Delta Agent, Sentinel-1 and Sentinel-2 imagery, and the API. Paid plans add events as they happen, the full account and the evidence behind each one, a longer look back, night lights, NISAR L-band radar and change detection.

One real event, as each plan sees it

A live event from the last three days, picked automatically — not a mock-up. Switch plans to see what each one opens. Sections a plan does not open are shown locked.

Open this event's public page

Two things decide what you pay

No seats and no overage charges. When the month's tokens run out, metered actions pause until the next cycle — or you top up.

Your plan decides what you can open

Which satellites, whether you see today's events, how much of each event you see, how many places you can watch, and whether you may use the results commercially. The table below lists it all.

Tokens pay for the work you run

Each plan comes with a monthly allowance. Reading the Watchfloor, the daily World Brief and reports is free, and so is creating a watch. Your balance and each action's cost are shown as you go.

Pricing FAQ

What is free, and what needs a paid plan?▼
Free covers world events on the Watchfloor up to the previous day, Sentinel-1 radar and Sentinel-2 optical imagery on the map, terrain, every reference overlay, the Delta Agent, a Watchlist of three, one monitored area, and the REST API, MCP server and Python SDK. Starter adds VIIRS night lights, NISAR L-band radar, change detection, today's events as they happen, the full detail of each event, event search and filters, 30 days of dates to pick from and the weekly roundup. Pro adds the evidence behind each event (every source, related events, the imaging recommendation, market reasoning), the full record, the monthly brief, room to watch at scale, and the commercial-use license. The comparison table on this page lists every line.
Are thermal anomalies included?▼
Every plan shows on the Watchfloor map that a satellite measured an anomalous heat source, when, and where. The measurement itself — which facility or place it was near, how strong it was, how it compares with the weeks before, and the reporting linked to it — comes with the full account of each event; the comparison table shows which plans include it. The same rule applies in the app, to the Delta Agent and over the API.
Are transit anomalies included?▼
Every plan shows on the Watchfloor map each strait and canal where ship transits are measured, and whether they are within their usual range. The numbers — how far from the usual level a place is, the index and the trend — come with the full account of each event; the comparison table shows which plans include it. The same rule applies in the app, to the Delta Agent and over the API.
Are night-light anomalies, SO2 anomalies, earthquakes near facilities and cyclone wind exposure included?▼
Every plan shows on the Watchfloor map that one of these was recorded, its kind, when, and where. The detail — which city, volcano, facilities or storm it is about, and the values — comes with the full account of each event; the comparison table shows which plans include it. The same rule applies in the app, to the Delta Agent and over the API.
What are tokens and how are they used?▼
Your plan decides what you can open; tokens pay for the work you run with it. Tokens are deducted by operation. Tile requests, imagery searches, assessments, monitoring runs, and Analyst questions have different costs. Estimated and maximum costs are shown before execution. Reading the Watchfloor, the daily World Brief and reports is free, and so is creating a watch. A map tile is metered by its pixels, band count and processing type, so panning at a high zoom over a large area costs more than a single view, and tiles already cached in your browser cost nothing. The token guide lists the cost of every metered action.
What does a month of tokens get me?▼
A Delta Agent question is billed by the work it needed: from 5 tokens for a light one up to 123 for a heavy, tool-using one, with a typical question around 45. A quick event assessment is 5, change detection is 10 per run, and a page of signals over the API is 1 token per 10 signals returned, with a minimum of 3. Your balance and what each action cost are shown as you go, so you can size a month from your own use.
What happens when I run out of tokens?▼
Metered actions pause until your next cycle: new satellite tiles, analyses, Agent questions and API calls. Reading the Watchfloor, the daily brief and reports keeps working. There are no overage charges. On a paid plan you can continue right away with a one-time token package; on Free, upgrade or wait for the reset.
Do tokens expire?▼
Your monthly plan allocation resets at the start of each billing cycle — unused monthly tokens do not roll over. Tokens from one-time packages (available on paid plans) are separate: they never reset monthly and stay valid for 365 days from purchase, so you can spend them at your own pace on top of your monthly allowance.
Is there a free trial?▼
Yes. Your first Starter or Pro subscription starts with 3 free days. Cancel during the trial and you are not charged. The Free plan needs no card and does not expire.
Which plan is right for me?▼
Start on Free and use it on a place or an event you care about. Move to Starter when you hit something Free does not open — night lights, NISAR, change detection, today's events, or the full detail of an event — or when you want to watch more than a few places. Choose Pro when you need to see why an event is placed and weighted the way it is (every source, related events, the imaging recommendation), when you use Delta in commercial work or client deliverables, or when you run monitoring and the API at scale. The API and MCP server are on every plan, so you can build on Free and upgrade when the work needs it.
Can I upgrade or downgrade my plan?▼
Yes, you can change your plan at any time. Upgrades take effect immediately, with a prorated charge for the rest of the current cycle. Downgrades — whether switching to a lower-priced paid plan or moving to the Free plan — take effect at the end of your current billing period: you keep your current plan and tokens until then, with no refund for the remaining time.
Can I cancel my subscription?▼
Yes, you can cancel anytime from the billing portal. Your access continues until the end of the current billing period.
What payment methods are accepted?▼
We accept all major credit cards (Visa, Mastercard, American Express) and debit cards through our secure payment processor Stripe.
Is commercial use allowed?▼
A commercial-use license is included with the Pro and team plans. The Free and Starter plans are for personal, educational, and evaluation use only — upgrade to Pro for business use, client deliverables, or paid distribution. The license covers Off-Nadir Delta's own output (event records, summaries, assessments and exports); source articles remain their publishers'.
