Baselight Assistant
Free natural language query over 70,000+ public datasets — shut down July 7, 2026 when the Finisterra team joined Chainalysis.
Baselight is gone — Finisterra's team joined Chainalysis and shut the product down on July 7, 2026. When it ran, it did one job well: plain-English queries across a 70,000+ dataset library sourced from the Census Bureau, CDC, BLS and FBI, free and without an account. There is no export or archival path left, so it cannot be part of your workflow today. If you need natural language query over public data, look at Google Dataset Search or Data.gov instead, and treat Baselight as a lesson in depending on venture-funded free tools.

Skip Baselight if you need a working natural language data query tool today — it shut down on July 7, 2026 and offers no export, archive or successor product.
The real cost was the shutdown: Baselight went offline July 7, 2026 with no export or archival option, so any bookmarked queries or digests you relied on simply disappeared.
Baselight was free for everyone — solo researchers, journalists and small teams all paid $0, with no account required for basic queries. There was no paid tier to grow into, so it never fit organisations that needed contracts, SLAs or programmatic access, which pushed those buyers toward paid data platforms or direct sources like Data.gov. That absence of revenue is part of why the product did not survive.
In short
Baselight Assistant — Free natural language query over 70,000+ public datasets — shut down July 7, 2026 when the Finisterra team joined Chainalysis. Best for Readers researching what Baselight did before its July 7, 2026 shutdown, Analysts studying platform risk in free, VC-funded data tools. Free to use.

About Baselight Assistant
Baselight Assistant was a free, browser-based tool for querying structured public data in plain English. You typed a question — something like a request for census population figures or CDC disease counts — and it returned matching datasets drawn from a library the vendor put at 70,000+ datasets across 90+ sources, including the US Census Bureau, CDC, BLS and FBI. You could combine data across sources, browse galleries of public dashboards and datasets, review your query history, and subscribe to curated daily digest emails. Basic queries did not require an account, and there was no charge to use it. Finisterra, the team behind Baselight, announced on July 7, 2026 that it was joining Chainalysis, and the product was shut down as part of that transition. The site now shows only the farewell notice — there is no archival mode, no export path and no successor product. If you need natural-language querying of public data today, you have to look elsewhere, and the Baselight story is now mainly useful as a case study in platform risk for free, venture-funded tools.
Behind the Verdict
Baselight's appeal was narrow but real: it removed the annoyance of hunting for public datasets by hand. You asked a question in plain English and it pointed you at structured data from named government sources — the vendor cited the US Census Bureau, CDC, BLS and FBI among 90+ sources behind a library of 70,000+ datasets. It combined data across sources, let you browse dataset and dashboard galleries, kept query history, and emailed curated daily digests. Basic use needed no account and cost nothing, which made it an easy first stop for a journalist checking a figure or a researcher scoping a topic. The weakness was structural rather than functional. A free tool with no API, no on-premise option and no paid tier had no obvious way to convert heavy usage into revenue, and it depended entirely on the team staying interested and funded. That ended on July 7, 2026, when Finisterra announced it was joining Chainalysis and shut Baselight down, with no export or archival option offered. The practical lesson for anyone evaluating tools in this category: if a free data product sits between you and your work, check who pays for it before you build a habit around it. For teams that need dependable, programmatic access to public data, a paid platform or a direct source like Data.gov is the lower-risk choice.

Real-world workflow fit
Concrete scenarios for the personas Baselight Assistant actually fits — and what changes day-one when you adopt it.
Before July 2026, you would type a plain-English question into Baselight, get pointed at Census or BLS datasets, and cross-check a figure across sources without hunting through agency portals.
Outcome: Fast sourcing while the product ran — but with no export path and the July 7, 2026 shutdown, that workflow must now run on Google Dataset Search or Data.gov.
You used the dataset and dashboard galleries plus query history to map what public data existed on a subject, and subscribed to the curated daily digest to catch updates.
Outcome: Useful discovery while the service was live; today the digest is gone and the same scoping has to be rebuilt on an alternative platform.
You review Baselight's July 7, 2026 shutdown — Finisterra joining Chainalysis, no export offered — as a concrete example of what happens when a free VC-backed tool underpins a workflow.
Outcome: A clear argument for checking funding and revenue models before standardising on a free data product.
Use Cases
- Historically: ask a plain-English question and get pointed at matching public datasets without manual search.
- Historically: combine figures from multiple government sources — e.g. Census and BLS — for cross-analysis.
- Historically: browse pre-indexed public dashboards and datasets to scope a research topic.
- Historically: subscribe to curated daily digests of public data updates.
- Historically: pull cleaned structured data for pasting into spreadsheets.
- Today: study Baselight's July 7, 2026 shutdown as a platform-risk case study when choosing free data tools.
Limitations
- The decisive limitation is that Baselight no longer exists.
- Finisterra announced on July 7, 2026 that the team was joining Chainalysis and that Baselight had shut down as part of the transition.
- There is no archive mode, no data export and no successor product from the same team, so anything you built on top of it needs a replacement.
- Even before the shutdown, the product carried structural constraints: no API access and no on-premise deployment, which ruled it out for programmatic pipelines and for organizations with data-governance requirements.
- It was a free tool, which meant no support contract and no commercial leverage if you depended on it.

Free
$0/mo
Ideal for
Anyone who wanted quick plain-English lookups across public datasets without an account or a budget — now historical, as the service is discontinued.
What this tier adds
Starting tier and only tier: $0/mo with natural language query over 70,000+ datasets across 90+ sources, cross-source combination and daily digests — discontinued July 7, 2026.
Where the pricing makes sense
The company stage and team size where Baselight Assistant's pricing actually pencils out — and where peers do it cheaper.
Baselight was free for everyone — solo researchers, journalists and small teams all paid $0, with no account required for basic queries. There was no paid tier to grow into, so it never fit organisations that needed contracts, SLAs or programmatic access, which pushed those buyers toward paid data platforms or direct sources like Data.gov. That absence of revenue is part of why the product did not survive.
Setup time & first value
How long it actually takes to get something useful out of Baselight Assistant — broken out by persona, not the marketing-page minute.
As a browser tool with no account needed for basic queries, time-to-first-value was effectively minutes while it operated — you opened baselight.app and typed a question. That is now moot: the site serves a shutdown notice dated July 7, 2026. Replacing it takes longer, since you have to rebuild dataset discovery on Google Dataset Search, Data.gov or a paid platform.
Switching to or from Baselight Assistant
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual agency-portal searching: before July 2026, you moved to Baselight by typing plain-English questions instead of browsing Census, CDC and BLS sites directly.
- →From spreadsheet-only research: Baselight's cross-source combination replaced manually stitching figures from separate government downloads.
- ↗To Google Dataset Search or Data.gov: re-run your discovery there, since Baselight offered no export or archival path at shutdown.
- ↗To a paid data platform: needed if you require an API or programmatic retrieval, which Baselight never offered.
- ↗To direct agency sources (Census, CDC, BLS, FBI): the underlying public data Baselight indexed remains available from the original publishers.

Featured Head-to-Head Comparisons
Baselight Assistant vs Nectar Energy
If you're a commercial facility manager seeking active energy savings, Nectar Energy is the clear choice with real-time monitoring and automated controls. Baselight Assistant, while innovative, shut down in June 2026 and is not a viable option. For former Baselight users, Nectar Energy serves a different need; consider other data platforms for public dataset queries.
Baselight Assistant vs Screenplayiq
Unless you need backup for screenplay market analysis, Baselight Assistant is useless—it shut down on June 30, 2026. ScreenplayIQ is actively serving screenwriters and producers with financial prediction and structural feedback. Baselight Assistant was a free public data tool that is now defunct, so ScreenplayIQ is the only viable choice between the two.
Baselight Assistant vs Geologicai
GeologicAI is the only viable option for active use, serving large-scale mining with cutting-edge multi-sensor scanning and AI logging. Baselight Assistant offers no ongoing value as it shut down in June 2026. For data query needs, look elsewhere.
