Larsen Code Labs Engineering Portfolio
We are a high-performance AI Automation agency and bespoke software studio. In addition to architecting and deploying custom workflow systems for enterprise clients, we design, build, and operate our own proprietary SaaS product family.
Tonalyzer
An AI-powered tone coach for workplace communication. Tonalyzer integrates directly into Slack and your browser, analyzing your message drafts before you hit send to ensure your point lands exactly as intended.
Eight detectors, organized into three families.
Every draft is checked against detectors grouped by what kind of problem they catch — friction between people, unclear asks, and mismatched confidence.
Interpersonal Friction
Passive-Aggression
Catches wording that reads as pointed or resentful under a polite surface.
Condescension
Flags phrasing that talks down to the reader, intentionally or not.
Performative Bluntness
Identifies "just being direct" framing that's really about optics, not clarity.
Microaggression
Surfaces subtle, often unintentional language that can land as exclusionary.
Clarity
Unclear Ask
Flags messages that don't state what action is actually being requested.
Fake Urgency
Catches artificially inflated time pressure that erodes trust over time.
Calibration
Anxious Over-Qualification
Flags excessive hedging and caveats that undercut a message's confidence.
CYA Hedging
Identifies defensive language written to protect the sender rather than inform the reader.
BizBooks
A beautiful, zero-bloat bookkeeping and accounting application designed specifically for independent consultants, agencies, and single-operator service shops. BizBooks bypasses corporate ledger noise, providing high-clarity cashflow tracking, invoice generation, and real-time tax forecasting.
Double-Entry Precision
Strict double-entry bookkeeping made completely visual and straightforward. No hidden automatic categorizations that break your reconciliation balances.
Plain-Text Portability
Your accounting files are saved in an open JSON or CSV schema, letting you export, back up, or transfer your transaction history seamlessly without database locks.
Zero-Tracking Privacy
We never see your banking connections, transaction histories, or billing information. All processing runs locally in your browser sandbox.
GovScan (unnamed / R&D)
A secure mobile utility for iOS and Android built for instant, fully local verification of government-issued digital credentials. Engineered for rapid check-ins, event gatekeepers, and physical site security where internet connectivity is sparse and data sovereignty is critical.
mDL Cryptography
Decryption of ISO 18013-5 Mobile Driver's Licenses using hardware-bound keys directly on the device, checking certificates of authority in under 150 milliseconds.
Zero Cloud Footprint
Scanned credential data never leaves the mobile device, ensuring compliance with strict privacy mandates. No server logs, no external APIs, and no telemetry.
High-Velocity Parsing
Optimized visual scanner engines that process PDFs417 barcodes, QR codes, and NFC fields reliably, even in low light or glare conditions.
Common questions about our portfolio and agency services
How are these applications funded?
We are completely independent and self-funded. We build software that people pay for directly through subscription or licensing fees, aligning our incentives with building durable, reliable tools rather than farming user data.
When can I access BizBooks or GovScan?
BizBooks is in active internal alpha with private beta invitations planned for later this year. GovScan is in research stages as we monitor evolving mDL standard implementations across state and federal security landscapes.
Is my data shared with LLM providers?
No. Our AI integrations, such as the modeling backing Tonalyzer, operate via strict API protocols with zero-data-retention agreements, ensuring none of your workplace communications are ever used for model training.
Can I request custom features or integrations?
Absolutely. We work closely with our early-access users and enterprise partners to tailor our deployment pipelines. Get in touch with us on our contact page to discuss partnership potentials.
