What FILTERCODE LTD does

Filtercode Ltd is a privately-held, bootstrapped UK software company headquartered at 3rd Floor, 86-90 Paul Street, London EC2A 4NE, registered in England and Wales (company number 10554106). The company operates with a team of 1–10 employees and describes itself as building focused productivity and utility software alongside providing software engineering consultancy services. Its commercial footprint is primarily consumer-facing through the Apple App Store rather than enterprise sales.

The company currently ships two consumer products under distinct sub-brands. ThinkWeave is a productivity application for iPhone, iPad, Mac, and Apple Vision Pro that combines rich notes, linked tasks, projects, audio recording with on-device transcription, and Apple Intelligence-powered summarization, with data synced via iCloud. Folio is a private bill tracker and document scanner for iOS that uses on-device AI to extract structured fields — provider, amount, and date — from invoices and receipts captured by camera, eliminating the need for a bank login or any server-side processing. Both products share a privacy-first architectural posture: zero cookies, no analytics, no third-party trackers on the company website, and on-device computation wherever technically feasible.

Distribution is exclusively product-led via the Apple App Store, supported by dedicated per-product websites (thinkweave.app, folioscan.uk), a LinkedIn company page, and a GitHub organization (github.com/jandro-es). Revenue mechanics rely on App Store subscriptions/app sales through Apple's platform; no enterprise pricing, channel partnerships, or advertising-driven monetization is disclosed. The company has not raised institutional funding, has no parent organization, and operates without disclosed M&A or restructuring events in the available record.

Direct peers

• Scanbot: Scanbot offers mobile document and barcode scanning with on-device AI for data extraction, distributed via App Store subscriptions. Overlaps with Folio on receipt/invoice scanning and on-device processing approach.
• Cultured Code (Things 3): Maker of Things 3, a premium task and productivity app for Apple platforms (iPhone, iPad, Mac). Comparable as a small, focused, Apple-only productivity studio selling directly via the App Store with a privacy-respecting, design-led approach.
• Genius Scan: Genius Scan is a mobile document-scanning app that uses on-device processing to capture receipts and documents. Directly comparable to Folio's on-device document scanning and provider/amount/date extraction features.
• Craft Docs: Craft offers notes, documents, and tasks tightly integrated across iPhone, iPad, and Mac. Compares directly to ThinkWeave on Apple-platform productivity, cross-device sync, and consumer/team subscription GTM.
• Shiny Frog (Bear): Bear is a notes and writing app for Apple devices with markdown support, iCloud sync, and a privacy-conscious stance. Direct peer to ThinkWeave given similar Apple-platform focus, notes-as-core use case, and subscription App Store distribution.
• Obsidian: Obsidian is a markdown-based, local-first notes app popular among power users on Apple platforms. Comparable to ThinkWeave on notes-first productivity, privacy-respecting local storage, and indie-software positioning.
• You Need A Budget (YNAB): YNAB is a subscription-based personal budgeting and bill-tracking app sold directly to consumers, including on iOS. Comparable to Folio's bill/subscription-tracking use case for privacy-minded individuals managing personal finances.

Broad incumbents

• Notion: Notion is a much larger productivity suite spanning notes, tasks, databases, and projects across web, mobile, and desktop. Competes with ThinkWeave on the productivity/workflow category but operates at vastly greater scale and cross-platform breadth.
• Apple Notes: Apple's first-party Notes app ships free on every Apple device and now supports AI-driven summarization, document scanning, and task management. The most significant substitute threat to ThinkWeave given zero cost and deep OS integration.

Emerging players

• Monarch Money: Monarch Money is a subscription-based personal finance and subscription-tracking app with iOS support. Competes with Folio in the consumer bill/subscription-tracking category with a more collaboration-oriented feature set.
