02THE TOOLKIT
Nothing extra for the sake of it
Everything the page
needs next.
Rekha keeps everyday PDF work close together, so you do not have to jump between a reader, a scanner, a file manager, and a dozen small tools.
02↗
Shape the pages
Merge, split, reorder, compress, and convert when a document needs a new version.

03AI, EXPLAINED
A useful boundary
Helpful, bounded,
easy to question.
PDF chat sends a limited page window with your question instead of silently sending an entire document. Rekha tells you which pages were included, so you can ask for another range when needed.

05QUESTIONS
The short answers
Before you
open the page.
Is the app free?
The Android build is available through the public release repository. Some AI features may have usage limits or require an account.
Where do official builds come from?
The private build pipeline publishes the signed release assets to the public Rekha-releases repository. That is the only download source linked by this site.
Can Rekha update itself?
Rekha can notify you when a new build is available and open the official APK installer. Android still asks you to approve the update; installs are never silent.
Why did PDF chat return no answer?
Check your connection and sign-in status, then try a smaller question or send the page range that contains the answer. AI answers can be imperfect, so check the cited page.
How do I request data deletion?
