We Build Free Apps ThatRival the Paid Ones
Novus Stream Solutions develops free, ad-supported tools that deliver the features most software companies charge a premium for. Eight apps are live today — AI background removal, beat-synced music visualizers, a PDF studio, private file conversion, source-grounded study, 2,428 generated test files, a synthetic probability research lab, and a privacy-first AI history dashboard — plus Novus Striker arcade soccer in early development.
Advertising helps support the free apps, and more products are already in build. Product guides live in documentation, updates and field notes on the product blog.

The ecosystem · 01
NSS Background Remover
One-click AI background removal that runs entirely in your browser — for images, video, and GIFs — plus image and video editors, upscaling, and 32 tools in total. Your files never leave your device.
- AI cutouts with edge refinement — free at full resolution, batch up to 100
- Image & video editors with layers, 22 filter presets, and 2×/4× AI upscaling
- Private by design: processing happens on your device
The ecosystem · 02
Novus Visualizers
Turn any track into a beat-synced music video. Nine engines carry six modes each — 54 in all — across a guided Classic editor and a node-based Studio, exported with no watermark and no render queue.
- Nine engines × six modes, all beat-locked to deterministic timing
- Classic editor or node-based Studio — one document, one renderer
- Free account adds saved projects, albums, and community remixes
The ecosystem · 03
Novus PDF Studio
One private hub for every PDF job. Seven page tools handle merge, split, organize, rotate, numbering, protect, and unlock — and the editor fills, signs, and marks up, all in the browser.
- AI field scan finds the blanks, including signature lines
- Seven page tools plus AES-256 password protection
- Draw signatures and export a vector PDF with selectable text
The ecosystem · 04
Novus Convert
1,022 published conversion routes, all running in your browser. Mix images, media, documents, and archives in one queue, choose an output per file, and download only after validation.
- 1,022 routes across images, media, documents, archives, CAD, and fonts
- Mixed batches with a different output for each file
- A build-time check refuses to list a route that would quietly fail
The ecosystem · 05
Novus Learn
Follow the source, see the connections. Bring a topic, a URL, a paper, a video, a textbook, an upload, or a codebase — and get notes, flashcards, a quiz, and a concept map built from that source's own sentences.
- Nine input modes, from a Wikipedia topic to a JavaScript codebase
- Extractive, not generative — when the source can't answer, it says so
- Teacher Hub turns any project into a printable, cited lesson
The ecosystem · 06
Novus Examples
2,428 test files across 17 categories — generated, not collected. Every one ships with an exact spec sheet and a clean ↔ noisy twin, so a before/after test is one download away.
- Deterministic scripts, fixed seeds, and a spec sheet on every file
- Browse by purpose — OCR, ASR, segmentation, CSV parsing, JWT
- Twelve live targets for the things a downloadable file can't test
The ecosystem · 07
Novus Odds
Synthetic sports probability research. Seven labs and nine sport models generate fictional markets you can run a million events through, then measure EV, ROI, calibration, and variance — informational simulation only.
- Seven labs, nine sport models, and reproducible seeds
- A discrepancy detector that labels which signals need hindsight
- No deposits, wagers, or sportsbook accounts — every price is fictional
The ecosystem · 08 · early access
Novus Striker
Arcade soccer in the browser — pick a team, chain combos, bury last-second screamers. No download, no install, and still in active development.
- Play in the browser with nothing to install
- Over-the-top arcade matches with combo chains
- Early access — play now and send feedback
The ecosystem · 09 · private beta
Novus AI Stats
See everything you build with AI. Import ChatGPT, Claude, Gemini, Claude Code, Codex, and Gemini CLI history into one privacy-first dashboard — local-first parsing, honest metric quality labels, and share cards without exposing transcripts.
- Six providers — web chats and coding agents in the same frame
- Metric quality labels so estimates never masquerade as facts
- Private beta — free during beta, no payment information required
How We Build It
Every app we ship is free to access — ads keep the lights on, AI-assisted development keeps the build fast, and the roadmap keeps growing. Here is the playbook behind the ecosystem.
Free First
Every product is free to use by design. Ad support covers our costs, so you get real access — no paywalls, no stripped-down free tiers, no bait-and-switch.
Better Features
We benchmark against paid alternatives and build to exceed them. If a competing app charges $20 a month, our free version delivers the same — and then some.
Complete by Default
The core job stays open from start to export. Useful features belong in the product people can use today, not behind a speculative upgrade screen.
Built with AI
AI-accelerated development is behind every app we ship. It helps a small software business build, maintain, and keep improving an entire free ecosystem.

Why Novus Stream?
Great software shouldn't require a subscription. We build free apps that go head-to-head with paid products and compete on the quality of the complete experience, not on how quickly a paywall appears.
The portfolio currently spans images, creator video, PDF forms, private file conversion, source-grounded learning, and free sample files for testing. New apps join that lineup as they are ready, with documentation and practical tutorials published alongside them.
