Demo Coming This Summer 2026, $2 in free credits to try.

Open-sourcing the core is planned for this winter.

I'm also looking for early contributors.

See It In Action

The Chainlit web UI and CLI share one workspace via Meta-Bifröst (unified workspace bridge). Web: pick a Realm, ask anything, expand Yggdrasil Reasoning. CLI: parallel realms, live streaming, cited final answers with cost and source stats.

CLI demo (Odin mode): using parallel realms, web search, streaming thoughts, and tool calls as the answer builds.

Expand

CLI full answer: full output from the Odin mode demo above, fibromyalgia research with citations, run stats, and sources.

Web UI home: parallel reasoning intro, Ten Realms picker, and Web, Tools, and Images toggles.

CLI demo (no parallel): single-realm run for comparison, same CLI, with parallel execution disabled.

Chat UI demo: Fast Path in seconds. Expand the trace for Answer Extraction, realm routing, and the full chain.

Real-World Use Cases

Real-world use cases for Yggdrasil Agent include software development, research, data science, business analysis, and multilingual work. Yggdrasil Agent adapts to your task: from spreadsheet analysis to citation-heavy research.

Software Dev

Debug production issues, code review, architecture design, security audits

Research

Literature reviews, multi-language sources, citation-heavy reports

Data Science

Excel/CSV analysis, statistical modelling, trend prediction with Sindri (autonomous coding agent)

High Quality Research Sources

Evidence-based sources, PubMed priority, peer-reviewed evidence valued, trusted guidelines and citations

Business

Market analysis, competitive intelligence, strategic planning

Multilingual

Translation, cross-language research, localisation (12+ languages)

Weather / Aura

Conditions, forecasts, and ambient context for planning and mood

Brainstorming

Ideation, alternatives, creative exploration with parallel branches

Learning

Explain concepts, summaries, Q&A, and step-by-step tutorials

Writing / Content

Drafts, outlines, editing, and long-form content with cited sources

Math & STEM

Proofs, physics, formal logic. Kvasir (verified math reasoning mode) with DeepSeek-R1 and ToRA verification

Document / OCR

Invoice and receipt processing, form extraction, scanned PDFs with Veðrfölnir vision

A note from the creator<br>Open source, this winter

Open-sourcing the core is planned for this winter. I'm also looking for early open-source contributors who want to work on agentic architecture, evaluation, open-source project maintenance, and especially the frontend from day one. The GitHub org is linked below for anyone who wants to follow the work.

Follow the work — contributors welcome from day one

Beyond the Chatbot

A typical AI answers once and moves on. Context bloats. Wrong paths finish. Yggdrasil explores from multiple angles, checks its own reasoning, and lands on one answer it can account for.

Where Yggdrasil Fits

Some tools code. Some deliver work. Some automate apps.<br>Yggdrasil consolidates those strengths in one stack, then validates the answer.

Different jobs. One stack.

Research breadth<br>Manus · Deep Research<br>Broad research agents. Sources, subtasks, one merged report.

Finished deliverables<br>Perplexity Computer<br>Cloud digital worker. Describe the deliverable. Models, connectors, background runs.

Coding loops<br>Cursor · Codex · Claude Code<br>Repo coding loops. Edits, refactors, terminal work, pull requests.

Personal automation<br>Hermes · OpenClaw<br>Self-hosted personal agents. Messaging, apps, skills that compound.

One Stack. Validated Answer.<br>Research, tools, code, files, connectors, long sessions. Pulled into one place.

Research: sources. Workers: routing. Code: sandboxes. Personal: memory.

◆ Multiple perspectives : evidence, synthesis, challenge, and first principles in parallel

◆ First-principles checks : what is known, what breaks, what would change the answer

◆ Conflict scoring : evidence strength, source independence, real separation between answers

◆ Echo-chamber checks : same sources do not count as independent agreement

◆ Cross-provider judging : scoring spans multiple model providers

◆ Self-fixing retries : weak drafts retried and checked against evidence

◆ Failure memory : remembers dead ends, not just preferences

◆ Fuller field view : evidence, conflicts, tradeoffs, and why this answer

GAIA scores vary widely by harness. The same model can swing by tens of points on tooling alone (see Princeton HAL). Public leaderboards mix bare models, custom scaffolds, and managed agents. Any figures here are self-measured on Yggdrasil's own harness and offered as a reference point, not...
