Desktop app for Microsoft 365

Find what you need.
Gather it into one place.

Search accessible SharePoint content, your own OneDrive and your own mailbox from one desktop app. Search, filter, preview and open originals for free. When you need a handover, collect selected files and emails in a local ZIP with a collection trial or paid plan. Microsoft 365 copying is optional.

Free discovery, with no trial clock. Start the 21-day collection trial when ready. No card required.

Find and review for free

Connect SharePoint, My OneDrive and My mailbox with read access. Search the sources you choose, filter results, preview and open originals. Keep using discovery after the collection trial ends.

Pay for the collection work

Use a trial or paid plan to gather selected documents and full .eml messages in one local ZIP. No destination library or tenant writes are needed. Optional Microsoft 365 copying is separately enabled.

Direct to Microsoft

No Sightline content proxy or hosted storage. Your desktop talks directly to Graph and SharePoint. Local previews, reports and ZIPs contain downloaded information; store and share them responsibly.

Documented handover

Give the next person context, not just a folder.

Each collection ZIP includes a readable summary, file index and content hashes alongside the actual files in each ZIP. Show where each item came from, what was selected, and which downloads failed — so a colleague can review the handover without reconstructing your work.

Collection records document selected accessible results; they do not certify legal admissibility, trusted timestamps or a complete tenant search.

Built for

Legal, compliance, and IT teams who need answers fast.

Subject request preparation
Collect relevant documents and messages you can access. Sightline is not a complete legal discovery or hold system.
Matter and claims packs
Gather selected content into a local ZIP for review, with recorded run outcomes.
Due diligence preparation
Search accessible project content and your own communications before a handover.
Personal handover
Review your own OneDrive and mailbox and package selected work for the next person.
No hosted content proxy. Sightline 365 talks directly to Microsoft APIs. A local ZIP is outside Microsoft 365; follow your organisation's storage and sharing policies.
