AI does the heavy lifting, people stay in charge
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three stated task modules. Use deterministic code for graph construction, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One repository scope and supported language set; final architecture and correctness checks remain engineering. A model suggestion is never a verified fact, professional decision or authorization to act.
What your team sees
Primary screens: Repository connection and scope, Editable map workspace, Review and delivery. Use a thumbnail gallery for repositories and saved workspaces, a large central infinite canvas for diagrams, and a right-hand panel for source links, dependencies and comments. Let users compare diagram versions side by side. Display draft, changes requested and approved states. Provide a review link with comments anchored to the relevant code element. Make the task-specific outcome reviewer-approved source-linked code maps visible beside its evidence, review state and value baseline.
Accounts and administration
Project ownership, repository versions, review comments, approval states, access allowances, diagram limits, export history and a rights record for supplied code. Add organization access boundaries, named reviewers, usage caps, data retention controls, export logs and explicit approval for external actions.
Integrations and data access
Customer-owned repositories, authorized git providers and permitted documentation sources. Cloud code storage, IDE plugins and CI destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
How we build it
We build with our own AI software development factory, so most implementations take days to a few weeks of creation time, not months. You see working software at every step, and exact timing depends on availability.

Why we start with an MVP
An MVP, or minimum viable product, is the smallest version that your users can actually work with. It is not a cheap version of the full solution. It is a test, built to answer the questions that decide whether the rest is worth building.
- Pick the riskiest assumption. Here: will engineering leads and platform teams maintaining large or legacy codebases use it to solve "developers and reviewers cannot quickly see how modules, dependencies and features connect, so onboarding, change review and impact analysis take repeated manual tracing"?
- Build only what tests it. One team, one use case, a few core modules. People do the rest by hand for now.
- Run a paid pilot. Agree quality and outcome thresholds before the pilot using this measure: Accepted maps per engineering hour and corrections after review.
- Measure, then decide. Track accepted maps per engineering hour and corrections after review; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase. Then expand, change course or stop, with evidence instead of opinions.
MVP scope for this solution. Pilot scope: One repository scope and supported language set; final architecture and correctness checks remain engineering. Implement one approved input format, a bounded representative case set and the first two task modules: connect a repository and select scope; generate interactive clickable diagrams of code structure. Support the third module with operator review: map dependencies between modules, functions and components. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.
After the MVP. Once paid pilots prove usefulness, automate repeatable reviewed steps and add one verified source integration. Expand supported inputs and case volume only after new evaluation cases pass. Build reusable customer configurations and recurring value reports around reviewer-approved source-linked code maps. Retain the explicit scope boundary: One repository scope and supported language set; final architecture and correctness checks remain engineering.
What the build depends on. Repository upload and preview, asynchronous generation jobs, editable version history, reviewer access and tested export formats. High-fidelity production requires specialist engineering QA. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One repository scope and supported language set; final architecture and correctness checks remain engineering.

Selling it to your own clients: the go-to-market playbook
Pricing to test
Test a USD 300-1,500 fixed pilot for one defined repository package. Offer a monthly production allowance after repeat demand. Quote complex multi-repository or specialist integration work separately. These are test prices, not market benchmarks. Package the initial sale as one bounded reviewer-approved source-linked code map. Recurring fees must specify volume, review depth and integration support. For exchanges, test a disclosed coordination or successful-service fee rather than holding customer funds. Reprice only after measuring real delivery labor; platform-build cost is separate from a commercial pilot fee.
Message to test
Reduce manual code tracing while keeping every diagram linked to its source. Demonstrate a concrete reviewer-approved source-linked code map using the buyer's approved example and show the baseline, corrections and actual delivery effort.
Where to find buyers
Engineering leads and platform teams maintaining large or legacy codebases professional communities; specialist consultants serving this buyer; permissioned partner introductions; practical demonstrations at relevant trade or practitioner events.
Lead magnet
A reviewed sample reviewer-approved source-linked code map from a small authorized input set, with a transparent calculation of accepted maps per engineering hour and corrections after review and no promised savings.
The first 30 days
- Week 1: interview five engineering leads and platform teams maintaining large or legacy codebases and inspect a recent example of developers and reviewers cannot quickly see how modules, dependencies and features connect, so onboarding, change review and impact analysis take repeated manual tracing.
- Week 2: prepare a consented or synthetic demonstration of the three task modules.
- Week 3: seek one bounded paid pilot with agreed baseline and acceptance criteria.
- Week 4: measure accepted maps per engineering hour and corrections after review, reviewer effort and repeat-purchase interest. This is a demand-validation plan, not a thirty-day full-product delivery promise.
Paid pilot
Agree quality and outcome thresholds before the pilot using this measure: Accepted maps per engineering hour and corrections after review. Continue only if the buyer accepts the actual output, the intended job outcome improves without unacceptable errors, and measured delivery cost fits willingness to pay. Revise or stop if access is unavailable, qualified review cannot be provided, or apparent savings disappear after corrections and support. Use held-out cases when comparing model quality; use a properly reviewed comparison design before making causal claims. Record missing cases and negative results alongside successful outputs.
Success metrics
Accepted maps per engineering hour and corrections after review; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase.
Retention and expansion
Repeat the workflow when the buyer again needs reviewer-approved source-linked code maps. Retain permissioned settings and reviewed examples, report realized value honestly, and sell increased volume or adjacent approved workflows only after contribution margin and quality remain acceptable.
Why clients would pick it
A reusable library of approved diagram styles, repository constraints and review examples, together with reliable delivery for a narrow engineering niche. Build a permissioned library of representative task cases, reviewer corrections and verified operating constraints for engineering leads and platform teams maintaining large or legacy codebases. Repeatable delivery and useful integrations matter more than access to a base model.
Alternatives and positioning
CodeViz (YC S24), Eraser AI, ProductMap AI, Codalogy, Haystack, manual tracing and generic diagram tools. Compare this product with the buyer's present method on accepted maps per engineering hour and corrections after review. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.
Main delivery costs
Model inference attempts, repository parsing and storage, reviewer hours, client revision rounds and licensed source assets. Additional initial validation requires representative authorized sample preparation, buyer interviews, buyer-side evaluation and bounded validation of reviewer-approved source-linked code maps. Track cost per accepted output, including correction work, unsuccessful cases and support.
Safeguards
Preserve source attribution, code accuracy and usage permissions. Engineering leads approve substantive changes and publication scope. One repository scope and supported language set; final architecture and correctness checks remain engineering. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
