§ 01 — ManifestoSable / Launch editionp. 02

Most research is a guess wearing a citation. We skim forty tabs, trust the most confident sentence, and hope nobody asks where it came from. Sable doesn’t skim. It reads every filing, paper, transcript and footnote — then hands back only what it can claim prove.

Four movements.One brief you can defend.

Watch Sable work a real question end to end — from a messy prompt to a two-page brief where every sentence carries its receipt.

Ask.

Ask like you’d ask a sharp colleague.

Type a real question — messy, specific, opinionated. Sable turns it into a research plan you can edit before a single source is read.

Sodium-ion takes a real share of new grid storage by 2030 — but it won’t displace LFP.

Sodium-ion cell costs are on track to undercut LFP by 20281, and cycle life now clears daily-cycling duty2. The binding constraint is hard-carbon anode supply3, which caps a realistic 2030 share at 18–24% of new deployments4.

§ 05 — FAQSable / Launch editionp. 06

Fairquestions.

Anything else? Sable would read the docs for you — but here are the ones people ask first.

  • Anything with provenance: regulatory filings, peer-reviewed papers and preprints, patents, earnings-call transcripts, court dockets, procurement tenders, public datasets — plus the private documents you connect. It reads them end to end, including tables and footnotes, and scores every source for provenance before it is allowed to support a claim.

  • Every sentence in a brief is linked to one or more exact passages — document, page, paragraph, and the quoted span. Click a citation and the source opens at that line. If Sable can’t point to a passage, the sentence doesn’t ship.

  • Disagreement is information, so Sable keeps it. Each claim carries evidence for and against, a calibrated confidence, and a note on why the strongest counter-evidence was or wasn’t outweighed. Contradictions it can’t resolve are flagged for you instead of averaged away.

  • Yes. Desk plans connect data rooms, drives and PDF archives as private corpora. Your documents are cited exactly like public sources and are never used to train shared models.

  • Median eleven minutes for an exhaustive brief of around five thousand sources. You can watch it read in real time, steer the plan mid-run, or close the tab and get an email when it’s done.

  • No — Sable is a design and engineering concept by Cristhian Tilleria, exploring how an AI research product could look and feel at public launch. All names, figures and quotes are fictional, and the waitlist form is a demo that sends nothing anywhere.
