Invitation-only beta · US

Deep research you can check, line by line.

Sidereal Research discovers and interrogates real sources, assembles an evidence corpus you can inspect, and drafts long-form, fully cited reports — then ships a proof for every sentence, re-verifiable against the source it claims.

Where most AI research asks you to trust it, Sidereal is built to be checked.

Our mission

We build AI that produces work you can actually rely on — research meant to be checked, not merely believed.

Sidereal Intelligence is a research-technology company. Our platform, Sidereal Research, exists to close the gap between fluent answers and trustworthy ones: discover real sources, assemble an evidence corpus you can inspect, and defend every sentence against the source it claims.

Discover & interrogate

Real sources located across 28 backends, then vetted, fetched, and graded — not recalled from a model's memory.

A corpus you can inspect

Every claim, conflict, and citation lands in a manifest you can open and audit — before a single word is drafted.

A proof for every sentence

Each cited line is graded against its source and ships re-verifiable — where others ask for trust, we ship the receipts.

Why Sidereal is different

Trust isn't a tone of voice. It's a mechanism.

Five things every Sidereal report does that most deep-research tools don't.

01

Per-sentence citation audit

Every sentence is graded against the source it cites — supported, partial, or unsupported. Weak claims are healed or flagged before they ever reach you.

Most toolshand you fluent prose and hope you don't check.
Siderealgrades every sentence and shows its work.

The record converges on one asset: density of federal infrastructure — over 70 federal laboratories2, alongside major research universities. That combination translates directly into startup formation3 as procurement shifts, though most founders relocate within two years.

■ supported 86% ■ partial 9% ■ unsupported 5%
02

A proof for every sentence

Open any claim to see the exact source, the quoted passage, and a live link — re-verifiable whenever you like, not a dead footnote.

Most toolsdrop a URL and move on.
Siderealattaches a re-checkable proof to each line.

03

Conflict & corroboration ledger

When sources disagree, we surface it as a conflict — never averaged into one confident number. Independent corroboration is tracked and shown, too.

Most toolsblend contradictory sources into one answer.
Siderealkeeps the disagreement visible.
⚑ 2 conflicts ✓ 3 corroborations

An inspectable evidence corpus

Before a word is drafted you can browse the full manifest: every source, its type, its claim strength, and its bias-as-data. No black box between prompt and answer.

Researched live from real sources

Reports are built from live retrieval across peer-reviewed literature, government records, archives, code, and the open web — current sources, not the model's stale memory.
