Recollect

Recollect scans images with Tesseract OCR, indexes extracted text in a local SQLite database (via Gom), and provides a fast search UI built with GTK4 and libadwaita.

Features

• OCR-powered image text search: direct Tesseract C API, no CLI dependency
• Fast local search: SQLite database via Gom ORM
• List and grid view modes: toggle between compact results and thumbnail tiles
• Image preview sidebar: extracted OCR text and file properties at a glance
• Flexible search filters: fuzzy, case-sensitive, whole-word, and diacritics matching
• Sort by name or date: ascending or descending
• Date range filtering: narrow results by scan date
• Incremental file monitoring: folders are watched for changes and re-indexed automatically
• Downloadable language models: fast, balanced, and best Tesseract variants
• Onboarding wizard: guides first-time setup of folders and models
• Keyboard shortcuts: full shortcut reference available in-app (Ctrl+?)
• Background scanning: continues indexing even when the window is closed
• Internationalization: gettext-based translations
• 13 image formats supported: PNG, JPEG, TIFF, BMP, WebP, GIF, AVIF, HEIC/HEIF, JPEG XL, SVG

How it works

Recollect watches your chosen folders and runs each image through Tesseract OCR to extract its text. That text is stored in a local SQLite database, so searching is instant, with no re-scanning needed. When you type a query, Recollect matches against the indexed text and shows the matching images with a snippet of the recognized content.

Installation

Precompiled flatpak bundles are attached to each GitHub release. Download recollect.flatpak and install it:

flatpak install --user recollect.flatpak

Building from source

Dependencies (Arch Linux)

sudo pacman -S vala meson ninja gtk4 libadwaita sqlite tesseract \
               glycin glycin-gtk4 json-glib libsoup3

Other distributions: install the equivalent packages for each dependency.
A Gom-Vala fork is auto-fetched via meson wrap, so no manual setup is needed.

Build and install

meson setup build --prefix="$HOME/.local"
meson compile -C build
meson install -C build

The binary is installed to ~/.local/bin/recollect.

Troubleshooting

libgom.so.0: cannot open shared object file

If you see this error at runtime, the dynamic linker can't find the Gom library. Rebuild with the rpath fix applied (already included if you're using the latest build files):

meson setup build --prefix="$HOME/.local" --reconfigure
meson compile -C build
meson install -C build

Alternatively, set LD_LIBRARY_PATH:

export LD_LIBRARY_PATH="$HOME/.local/lib:$LD_LIBRARY_PATH"
~/.local/bin/recollect

Subproject gom-vala has no meson.build file

If meson setup fails with this error, it means the subprojects/gom-vala/ directory is missing its top-level meson.build. Ensure the repository includes subprojects/gom-vala/meson.build and subprojects/gom-vala/gom/meson.build with the correct include directory (pointing to '.', not '..').

Development profile

Use a separate application ID (org.laine.Recollect.Devel) so development builds don't interfere with the installed release:

meson configure build -Dprofile=development
meson compile -C build

Switch back to the release profile with:

meson configure build -Dprofile=default
meson compile -C build

Usage

CLI flags

Flag	Description
--reset	Reset all settings to defaults
--no-system-models	Skip system Tesseract models; only use downloaded ones
