ACCESS AND PRICING

Access and team evaluations.

Start with experimental free PRAXIS access within app limits. For a team evaluation, scope one policy workflow, its sources and a review test. Paid upgrades are unavailable; team support and data handling must be agreed before a pilot.

Current access and development boundaries

What you can evaluate

Current free access, subject to the limits shown in PRAXIS. Paid upgrades are unavailable. Future prices and features are proposals, not offers.

Full team assignment and source-change review shown on this websiteConcept preview / product direction
The Example Advisory workspace and outputs are authored fictional illustrations. The complete project-linked team journey and automated source-change impact review remain development work; existing agent execution is a separate foundation.
User, Situation, Tool and Output capsule formatsReference formats
Four downloadable examples illustrate the model. They do not establish four complete PRAXIS authoring paths.
Conversational ontology editing and lossless interchangeIn development
Full round-trip portability needs validation.
Agent execution, queued research, approval and saved outputsExisting runtime / recorded bounded flow
Agent execution and durable run records exist. A queued research and owner-approval journey was recorded. General completion, source fidelity and the project-to-runtime bridge remain unvalidated. Dated evidence →

BEFORE YOU START

The pipeline, ontology, and DIALECTICA reference work are published on GitHub. Check each repository for its license, development status, and setup requirements.

PRAXIS access and pricing are shown in the application. The document-and-chat workflow is the starting point; advanced agent and portability features remain under development.

A team evaluation starts with a defined question, an agreed source set, and review criteria. Timing, confidentiality, pricing, and support are agreed before the work begins.

We welcome practitioners and researchers who can help test a concrete workflow. Tell us about your use case and the constraints you need us to work within.

Common questions

What actually works today?+
Dated PRAXIS checks cover document uploads, capsule proposal review, attachment to chat and saved history. Its agent runtime executes queued work with approval and durable run records. The complete capsule-aware project adapter, lossless interchange and end-to-end team acceptance remain unvalidated. Research artifacts do not imply hosted API availability.
Can I try PRAXIS now?+
Yes. Open praxis.tacitus.me for the current app and plans. For an institutional workflow, contact us to agree a source set, review criteria, and a bounded evaluation before committing to a pilot.
Can I self-host the features shown in the products?+
Open-source repositories and reference artifacts have their own licenses and setup requirements. They are not a complete self-hosted copy of the PRAXIS service. Confirm the capabilities and license of the specific repository before adoption.
Which license applies to the open-source work?+
Check the LICENSE file in the repository you intend to use. Licenses vary: the current DIALECTICA v3 reference uses Apache-2.0, while some public research code has rights reserved. A public repository is not automatically available for unrestricted reuse.
Do you run paid pilots?+
Contact us to discuss an evaluation. A paid evaluation is a proposal requiring scope, duration, pricing, support and data-handling terms; this page is not an offer.
What about data privacy?+
Full details on /trust. Product security, provider processing, and institutional requirements need a deployment-specific review.

Discuss the right starting point for your team.
