Organized, trusted work with right-sized AI teams

ProofHorizon turns prompts into tasks and projects.Assembles the AI team.Verifies the evidence.

Start with a prompt—not a sprawling chat thread.

ProofHorizon automatically extracts structured tasks and projects your team controls, assigns the right agents from 400+ AI models, and runs every deliverable through automated gates, independent model review, and your human checkpoints.

Right-sized AI teams that perform better at lower cost

Every task logs its exact setup—models, tools, and reviewers—and records what survives verification. ProofHorizon uses that evidence to staff your next task with the most cost-effective configuration that delivers verified outcomes, not mere assertions, rather than defaulting to the biggest, most expensive model.

Prompt naturally while ProofHorizon builds a live tree of tasks, subtasks, and dependencies your team can edit, pin, and reorganize.

Automated Gates First

Deliverables hit deterministic rules and policy checks first. An independent AI model then cross-examines whatever survives them.

Human Sign-Off & Audit Trail

You decide where a person steps in. Every check stays permanently attached to the task, so work can be re-evaluated whenever conditions change.

Your team, your tools

An AI team assembled for your task.

Use ProofHorizon to coordinate new work or inspect the outcomes of the AI work your team already does.

Put a human–AI team to work

Describe what you need. ProofHorizon automatically assembles an AI team for the task within your scope, budget, and delegation limits. Add people and insert human checkpoints as needed.

Start with the work you already have

ProofHorizon for GitHub is the first entry point: deterministic PR verification, followed by deeper AI review and outcome insights. Bring your own model keys or discuss managed usage with us.

From ask to outcome

How the workspace works

Prompt our AI to assemble the team and extract the work. Tasks, subtasks, and projects stay organized automatically, with independent AI review before human review or approval.

01edit_note

Ask

Describe the result you need. Confirm the proposed task, deliverable, and acceptance criteria.

A task linked to the original ask
02hub

Assemble

Our AI assembles agents from over 400 models, within your scope and budget. Insert human checkpoints before work begins.

A team with clear boundaries
03memory

Collaborate

Tasks, subtasks, and projects stay organized as agents work. Follow dependencies, ownership, and handoffs in one place.

Organized work and deliverables
04verified

Review

At least one other independent AI model reviews the work before it reaches a person for review or approval. Inspect the result and its evidence together.

Evidence attached to the task

Improve

Learn which team configurations work for each kind of task, including failures, rework, and later outcomes.

gavel
ProofHorizon’s First Law of AI
“The system that says it completed the task should not be the same system deciding whether it succeeded.”
AI governance

Set the boundaries. Stay involved where it matters.

Authorize work when you assign it. Required checks follow the task’s risk; a smaller budget never removes them.

Clear authority

Trace work back to the original ask and the person or organization that authorized it. Keep the owner, author, and verifier distinct.

Limits that travel with the task

Set scope, spending, and delegation limits. Subtasks stay within the authority granted to their parent.

Insert human checkpoints

Choose where human review belongs in the workflow. Independent AI review comes first; “Needs you” brings people the results, evidence, and decisions that require their attention. Reserved decisions stay with the accountable person.

Governance for your environment

Discuss deployment, data access, retention, and model policies for your organization. Clinical work requires appropriate agreements and clinician oversight.

Where to start

One workspace. Different kinds of work.

Start with engineering and security workflows, where changes and checks provide concrete evidence.

Software engineering

Coordinate feature development, bug fixes, testing, and documentation. Preview what was built and inspect the changes and checks alongside the task.

Cybersecurity

Organize findings into remediation tasks. Assign implementation and independent review, track validation, and retain human control over infrastructure changes.

Healthcare quality improvement

Explore AI-assisted retrospective review and care coordination with clinical oversight. Keep patient context governed and clinician-reserved decisions with the responsible professionals.

Your existing workflow

Bring your current tools and agents into the conversation. We will help identify an initial workflow and the integration coverage it needs.

Team insights

Learn which teams deliver results.

Measure outcomes by kind of work and team configuration, with the evidence needed to interpret each result.

Capability with context

Compare team configurations with sample sizes, observation periods, and uncertainty in view. See “insufficient data” when evidence is sparse. An agent’s report alone does not establish success.

The cost of completed work

Track spend by task and project, including failed attempts and rework. Distinguish measured, estimated, and unknown costs when comparing verified completions.

Why ProofHorizon

Evidence behind the work.

Verification is part of the task, with a result you can inspect and a clear account of who did what.

Inspect the deliverable

Open the preview, changes, checks, and attribution from the task. Keep agent summaries visibly separate from the evidence supporting them.

Never rely on one agent’s word

An agent’s work or assertion is not enough. At least one other independent AI model should review any AI’s work before people need to review or approve it. Pair that review with deterministic checks and inspectable evidence.

Follow the outcome

Look beyond completion reports. Track whether a change was reverted, needed a fix, or remained stable over time.

A clear path to getting started

Our entry offering is free deterministic verification. AI execution and review draw on paid usage or capped credits; bring your own model keys or discuss managed models. Explore the workspace direction.
