Masonry gallery & instant keyword jump

Capture once. Keep organized. Find every word.

We reject synthetic blurs and cloud lock-in. InfiSnap pairs true-pixel scroll stitching with a calm, topic-driven screenshot knowledge library that lives entirely on your device.

True-Pixel Scroll Stitching

Fixed-layer modeling, row-majority consensus voting, and periodic disambiguation across dynamic feeds and chat wallpapers. Automatically cleans sticky bars, floating badges, and scrollbars while preserving real sampled pixels.

Topic Collections & Masonry New

Organize captures into custom icon-and-color topics with an automatic Unclassified view. One screenshot can belong to multiple topics, deleting a topic never deletes your images, and every collection browses in a real-image masonry grid.

Ranked Local Search & Filters

Decomposes multi-word queries on-device and ranks by keyword coverage and field relevance across titles, topics, tags, sources, and Vision OCR text. Filter by topic, source, tag, starred, or unread right inside the search bar.

Hold & Drag to Topic New

Long-press any screenshot card or list row and drag it directly onto an existing topic—or drop onto New topic to create and assign in one fluid gesture. Interactive edge-swipe navigation lets you move back and forth effortlessly.

Multi-Section Trim & Custom Share

Trim start/end screens or remove middle sections with magnified pixel handles. Share crisp 85% JPEGs using your editable title as a clean Unicode filename, or unlock Pro for footer-free PDF, lossless PNG, and custom JPEG quality.

Recoverable Trash & Markdown Export

Deleted captures move to Trash for 30 days by default (configurable 1–3,650 days) so nothing is lost by accident. Export your library's OCR text and topic structure as standard Markdown for any note app or AI agent.

Organize by topic. Browse in real-image masonry.

Your camera roll buries important screenshots between everyday photos. InfiSnap gives your long captures a quiet, structured home built around icon-tagged topics and visual recognition.

  • Multi-Topic Membership & Safe Deletion: Assign a screenshot to one or several topics by dragging, from the context menu, or in detail view—and create new topics right inside the chooser. Deleting a topic removes only the organization, never your images.
  • Automatic Unclassified & Consistent Masonry: Screenshots without a topic automatically appear in Unclassified. Every topic, All captures, and Starred view renders sharp, true-aspect previews in a two-column masonry layout.
  • Agent-Agnostic Markdown Export: Export titles, stable IDs, dates, source apps, topic names, and full OCR text as plain Markdown—ready for Obsidian, Notion, or any local AI workflow with zero cloud lock-in.

Original pixels are the highest respect to content

Conventional stitching apps either smudge boundaries with synthetic blurs, discard real repetitive messages, or fail when a chat has a fixed wallpaper or moving elements. InfiSnap adheres strictly to real sampled pixels.

  • Fixed-Layer Modeling & Row Majority Voting: Separates stationary bars, chat wallpapers, and floating badges from scrolling document pixels, voting out transient overlays while preserving authentic content.
  • Trim Ends, Remove Sections & Auto-Refresh: Trim leading/trailing screens or cut out middle sections anytime. Original sampled frames stay locally for 7 days so you can re-crop and receive automatic background stitch improvements.
  • Chunked 8-Language Vision OCR: Splits ultra-long screenshots into overlapping screen chunks so small fonts and cross-page lines are recognized accurately across English, Chinese (Simplified & Traditional), Japanese, Spanish, French, Korean, and German.
  • Visible Neutral Gap Stripes: If missing content cannot be proven continuous, an obvious diagonal stripe is inserted. Never gamble with legal, technical, or financial records.

Three steps to a searchable screenshot library

01

Capture or Import

Long-press Screen Recording in Control Center and choose InfiSnap while scrolling any app, or tap "+ Add capture" to import screenshots, a screen recording, or a web page.

02

Organize into Topics

Hold and drag captures onto existing topics or New topic, or browse unassigned items in Unclassified—all displayed in a consistent masonry gallery.

03

Search, Trim & Share

Filter by topic, jump to highlighted OCR text inside any long image, trim ends or middle sections, and share with clean custom filenames.

Everything you need to know

How do Topics and the Unclassified collection work?
You can create custom topics with 12 icons and 8 colors—either from the library home, inside the topic chooser, or by dragging a screenshot onto New topic. A single screenshot can belong to multiple topics at once. Screenshots not assigned to any topic automatically appear in Unclassified. Deleting a topic only removes that topic grouping—it never deletes your screenshots.
Why does a diagonal stripe appear on some stitched images?
This reflects InfiSnap's foundational principle: never fabricate missing content. When scrolling too fast skips critical frames, or when two segments lack reliable overlap, our engine inserts a visible neutral diagonal stripe with a review notice rather than guessing fake text. This ensures your captures remain trustworthy for legal, business, and personal records.
Does InfiSnap upload any screenshots, recordings, or text to cloud servers?
Never. InfiSnap operates with zero developer-hosted servers and zero third-party AI or analytics SDKs. Scroll stitching, chunked Vision OCR, and keyword ranking run 100% on your device. Microphone audio is never recorded during broadcasts. If you enable optional iCloud sync, your long screenshots and topics travel strictly through Apple's private CloudKit database tied to your personal Apple ID.
What is free, and what does the one-time InfiSnap Pro purchase unlock?
All capture, true-pixel stitching, topic organization, masonry browsing, on-device OCR search, Markdown text export, Trash recovery, and 85% JPEG sharing (including custom filenames) are completely free. Free exports append a small InfiSnap footer bar below your content. A one-time $2.99 lifetime Pro purchase (with Apple Family Sharing supported) removes the footer by default and unlocks More options: lossless PNG, multi-page PDF, and custom JPEG quality (10%–100%).
What happens when I delete a screenshot or clean up original frames?
Deleting a screenshot moves it to Settings → Trash, where it stays for 30 days by default (configurable from 1 to 3,650 days). Restoring brings back the image, title, topics, and notes; permanent deletion requires explicit confirmation. Separately, raw source frames (source-*.png) are kept locally for 7 days so you can adjust crops or benefit from automatic stitch updates, and can be cleared anytime in Settings → Storage without affecting your saved long screenshots.
Which iOS devices and languages are supported?
InfiSnap is crafted natively for iPhone (iOS 18.0+) and iPad (iPadOS 18.0+), adapting seamlessly to light/dark modes and Dynamic Type. The interface and on-device Vision OCR support English, Simplified Chinese, Traditional Chinese, Japanese, Spanish, French, Korean, and German.
