CommunicationOS

Search by meaning, not by wording

Describe what you remember. A result can match the topic even when you cannot recall the original words, and the same pass reads message text, voice transcripts and the contents of files.

Open originalCopy source link

One search across Alder Studio’s indexed history. The answer links to the messages it used, and each one opens inside the thread where it was written.

Search your archive without an expiry date

A conversation from five years ago opens the same way as one from this morning. Threads do not roll off after 90 days, and an older year is searched like a recent one.

No retention window

Search stays open for the life of the account on every plan. Conversations do not roll off after 90 days.

What the index holds

Timestamps, sender names, message text, voice transcripts and the text read out of images and files.

Imports from earlier tools

Bring the conversations already sitting in Trengo, Zendesk or another help desk into the same index.

Storage by plan

Starter holds 1 GB. Team holds 10 GB. Scale takes the archive to 1 TB. Enterprise limits are set in the order form.

Group chats indexed line by line

A busy project group produces more messages in a week than anyone reads. Each line keeps its speaker, so you can filter the room down to one person and read what they agreed to.

Speaker attribution

Filter a busy group chat down to one sender by name or phone number.

Side threads kept apart

A side discussion inside a room reads as its own thread rather than as noise in the main one.

Group digests

Read a short digest of an unread group before you answer it.

Indexed attachments in one place

A spreadsheet, a signed PDF and a screenshot from a phone sit in one list. Open a file and it takes you back to the message it arrived in.

Stored once

One checklist sent to eight people takes up storage once.

Original resolution

A photo or document keeps its original pixel count and metadata.

Search inside a file

Search for an invoice number printed inside a scanned PDF.

Link back to the thread

Every file keeps a link to the message it arrived in.

Keep the earlier version when a message is edited

Where the network supplies a revision event, the archive can retain the earlier version with its timestamp under the workspace privacy policy. That is the difference between remembering which date was agreed and being able to show it.

Ask the history a question in a plain sentence. The answer links to the messages it was built from, and each one opens in the conversation where it appeared.

Your archive only

The answer is built from your own conversations and from nothing on the open web.

Answers link to the messages used

Each sentence carries a link that opens the message it came from.

Gaps named

When the history does not hold the answer, the assistant says the record is missing.
