Cited, inspectable answers
References help users verify the answer against approved sources.
Private access controls
Authenticated agents and role-based administration protect private knowledge.
The buying problem
“Chat with your documents” is a category, not a complete evaluation.
The decision depends on who will use the agent, where it will live, how evidence appears, and who maintains it.
Audience mix
A public visitor experience and a private employee expert impose different access and design requirements.
Operating effort
Administration, source updates, deployment, and review matter after the initial demo.
The Chat.co approach
Where Chat.co is differentiated in the test
Evaluate the combined platform when cited research is one of several agent experiences you need.
Multiple agent shapes
Create website, internal, and specialist agents in one no-code environment.
Inspect the evidence
Attach sources to grounded answers so users can review the underlying material.
Provider choice
Use supported models from multiple providers without rebuilding source knowledge.
Flexible deployment
Use embeds, links, QR codes, API access, and documented MCP workflows.
Private AI by design
Frontier models. Your knowledge stays yours.
For foundation models accessed through Chat.co on AWS Bedrock, your inputs and the AI's outputs are not shared with model providers and are not used to train or improve their models. That protection comes from service terms—not an opt-out toggle.
Model-provider isolation
Prompts and files are processed inside AWS; model companies do not receive that traffic.
No training on your data
Inputs and outputs are excluded from provider training and model-improvement programs.
Enterprise controls
AES-256 at rest, TLS 1.2+ in transit, role-based access, SSO, and domain restriction.
Your data, your control
Export your information or permanently delete it whenever you choose.
Training and provider-sharing commitments reflect AWS Bedrock service terms for foundation models accessed through Chat.co.

From source to answer
Launch the first useful workflow in three steps
Start with a narrow, valuable question set. Prove retrieval and citations before expanding the source set.
- 01
Connect approved knowledge
Upload documents, crawl websites, add text or Q&A, and connect supported knowledge sources.
- 02
Configure the agent
Choose instructions, audience, access rules, appearance, model, and the behavior you want to test.
- 03
Deploy and improve
Publish the experience, review real conversations, and strengthen the sources behind weak answers.
High-value starting points
Choose the first workflow to prove
Use a representative source set and real questions. Evaluate answer quality, citation usefulness, access, administration, and total operating effort.
