As answered by people managing STEWARD by SOLEUM and JavaScript Tutorial.
STEWARD by SOLEUM's answer
Live data under the user's own login. Most embedded AI tools ingest your data and answer from a stored copy. STEWARD reads your REST API when the question is asked, with the signed-in user's own token. Answers reflect the record right now, and your existing permissions decide what each user sees.
A record your team owns. Every answer writes a full trace: prompt, response, source excerpts with provenance, tool calls and cost. Your team reads the same trace our operators read and can export every one.
A closed model path. AWS Bedrock is the sole model provider, reached through a private endpoint. AWS services alone process your content, and AWS commits that model providers never train on your inputs or outputs.
Bounded by design. Analysis code runs in a sealed sandbox with no network. Every turn has a hard deadline and a capped tool loop.
STEWARD embeds in any web product and ties you to no CRM, help desk or software suite.
STEWARD by SOLEUM's answer
STEWARD runs on AWS, with production and staging in separate AWS accounts.
STEWARD by SOLEUM's answer
STEWARD reads your live systems under the signed-in user's own login, at the moment of the question. No index and no copy of live records. Your API decides what each user sees, and STEWARD never holds a key.
Every answer shows its work. Inline citations point to the source excerpt. A full trace records the prompt, response, source excerpts, tool calls and cost. Your team sees the same trace our operators see, and every billed credit links to its trace.
When your material holds no answer, STEWARD says so and names the next step. No improvised answers.
AWS Bedrock is the sole model provider. No LLM API key exists anywhere in the platform.
STEWARD by SOLEUM's answer
Software companies and product teams who want an AI product expert inside their own product, serving their signed-in users.
STEWARD reads the host application's live data under each user's own login. The best fit is a web application with authenticated users and a REST API. Public sites without login get answers from the knowledge base only.
STEWARD serves four groups:
One engine, any industry. Built for the regulated. Works for everyone else.
STEWARD by SOLEUM's answer
Trust is the unsolved problem of the AI era. Institutions want AI. They need to trust it first. MIT NANDA's 2025 report, The GenAI Divide, found 95% of enterprise AI pilots show no measurable ROI.
Teams face a choice between full capability and control. STEWARD removes the choice. The expert reads live systems under each user's own login, answers only from the customer's material, and leaves a source and an audit record for every answer.
SOLEUM built STEWARD as a governed AI reasoning engine with a conversational surface. The leadership team is Donny Vanker (Co-CEO), Pablo Stefanini (Co-Founder and Chief Innovation Officer) and Anas Karkoukli (CTO). STEWARD launched publicly on 30 September 2026.
