Invite-only. Every new account requires a unique, one-time code.

Research report12 sources

What changed, why does it matter, and where does the evidence disagree?

Comparing independent evidence

Sereyx searches multiple indexes, reads the strongest sources, and writes a direct answer with citations attached to the claims they support.

CAPABILITIES

From quick answers to recurring research and finished work.

Five search modes

Best, Fast, Pro, Reasoning, and multi-angle Research with visible progress and inline citations.

Resilient search

Kagi, Brave, Tavily, and Google fallback with Web, Academic, News, Social, and Finance focus.

Choose your evidence

Search the web, private files, both, or neither, with date, domain, language, and region controls.

Collaborative Projects

Share instructions, files, pinned research, discussion, activity, and curated source collections with Project viewers and contributors.

Research on a schedule

Durable reports and recurring daily, weekly, or monthly tasks continue after you close the app.

Create with Studio

Turn research into native PDF, Word, Excel, or PowerPoint files, plus Markdown, CSV, and sandboxed standalone web apps.

Personal, under your control

Set response preferences and explicit memories that you can disable, edit, export, or delete.

Continue shared work

Open a read-only public report, then continue from a private copy in your own library.

Provider-neutral AI

Use Workers AI, Fireworks, or another OpenAI-compatible model without exposing keys to the browser.

Evidence health

See automated citation coverage, source usage, quality signals, diversity, and invalid-reference warnings for every answer.

Your source rules

Boost domains you trust and block domains you do not want retrieved, read, or cited across every search provider.

Private Data Lab

Profile CSV, TSV, and JSON datasets for quality, statistics, relationships, and chart-ready summaries inside your Worker.

Claim-by-claim verification

Use an optional independent model pass to classify important claims as supported, partial, unsupported, or conflicted against the retrieved evidence.

Connected knowledge

Sync read-only JSON APIs and RSS feeds with separate sync and search permissions, encrypted credentials, and private cached retrieval.

Native Office exports

Download editable Word documents, Excel workbooks, and PowerPoint presentations without adding a document server or leaving Workers.

HOW IT WORKS

A research trail, not a black box.

  1. Ask naturally.Choose a search mode, source set, focus, region, language, domain, or collaborative Project.
  2. Watch the work.Follow search, reading, comparison, and synthesis as each stage completes.
  3. Verify and continue.Review evidence health and semantic claim checks, save a reusable source collection, analyze a dataset, schedule a task from a template, or create a native Office artifact in Studio.

ACCESSIBILITY

Built to remain useful when vision is limited.

Sereyx uses semantic landmarks, complete keyboard navigation, generous touch targets, visible focus, screen-reader status announcements, scalable text, reduced-motion support, and an optional high-contrast presentation.

SIMPLE PRICING

Unlimited research, one plan.

Invited accounts can try Sereyx with a daily allowance. Unlimited removes the query limit across all supported models and search modes. Provider costs remain controlled by your deployment.
