Turn your inbox and calendar into a team mate.
Clastines gives you an AI worker with its own email, calendar, files and phonebook — built to do the work for people who live in client emails, calls and scheduling.
You hand it follow-ups, scheduling and admin. It plans, executes and logs the work, so your team can focus on conversations, not coordination.

Who Clastines is for
Clastines is built for people and teams who:
If you spend your mornings in email and your afternoons on calls, Clastines is for you.
Send 100+ emails a day to clients, leads or partners
Spend hours scheduling, rescheduling and chasing replies
Jump between email, calendar, call notes and files all day
Think: marketing & creative agencies, SDR / sales teams, consultants, founders and operators who live inside their inbox.
Why this matters
At least 7 million people in the UK already use generative AI for work — mostly through disconnected tools and stateless chat boxes.
They still spend hours re-explaining context, fixing AI drafts and manually coordinating email, calendar and files.
We estimate even a conservative 3 hours per week per AI-using worker is burned "babysitting AI" instead of delegating to it — roughly £20bn/year in lost productivity in the UK alone.
Clastines exists to turn that into a worker you can actually delegate to.
What it means to have your own AI worker
Clastines doesn't just answer prompts. It acts like a digital account manager that knows your clients, your tone and your schedule — and does the boring parts of client work for you.
Your tone & style
Your worker learns how *you* talk to clients: formal vs casual, short vs detailed, emojis or none, UK vs US spelling, sign-off rules for new leads vs long-term clients.
Your time
It understands your real working day: when you take calls, when you block focus time, the gaps you keep between meetings — and it schedules around them automatically.
Your people
Boss, account leads, key clients, warm prospects, vendors — your worker builds a graph of who matters, how they relate to you and which threads/projects they belong to.
Your files
Briefs, decks, scopes, contracts, reporting templates — your worker keeps its own file space linked to each client and project so it can pull the right doc without you hunting for it. This becomes *your worker's* memory of each client, not just another folder in Google Drive.
Your rules
You decide what your worker can send or schedule on its own (e.g. nudges, reminders, standard follow-ups) and what always needs your approval (e.g. new pitches, sensitive comms).
You stay in control
Every new memory or automation is proposed first — accept, edit or decline. Your worker learns your world, but you stay in charge of what it knows and what it's allowed to do.
Accept
Let Clastines remember this preference
Edit
Refine the memory to be more accurate
Decline
Skip this one—no memory created
The Story (how Clastines works for you)
From understanding your request to coordinating email, calls and files — here's how your AI worker runs client workflows in the background.
Assign
Tell your worker what you need in plain language:
"Follow up with all ACME leads who didn't reply last week, suggest 2 call slots for next week, and attach the latest deck."
Understand
Your worker pulls the context from its own workspace:
- Checks its email inbox for the ACME campaign thread
- Sees who opened but didn't reply
- Looks at its calendar and your calendar for free slots
- Grabs the latest ACME deck from its file space
Plan
It lays out the plan before acting — so you're never surprised:
- Draft follow-up emails in your tone for each contact
- Propose 2 times that work across calendars
- Attach the right deck
- Update its own task list to track replies & no-responses
Execute
With your one-tap approval, it does the work:
- Sends emails from its own address (or drafts for you to send)
- Adds tentative holds or follow-up reminders to calendar
- Files sent versions of the deck where they belong
Remember
It learns for next time (with your consent):
- Which follow-up styles get replies
- Which contacts prefer mornings/afternoons
- How the ACME project is structured in your files
- Which campaigns you're running this quarter

Real-life Examples
See how Clastines handles complex, multi-step tasks in your personal style — from documents to desktop automation to client scheduling.
You request:
"Chase everyone from last week's webinar who hasn't booked yet. Two gentle nudges over the next 10 days, then a firmer 'last chance' email."
Clastines delivers:
Finds webinar attendees and filters 'no meeting yet', drafts 2 nudges + 1 final email in your agency's tone, staggers send times to avoid spammy bursts, tracks opens, clicks and replies in its own workspace, flags hot replies for you and auto-archives dead leads.
Key Steps:
- Filters webinar attendees without meetings
- Drafts 2 nudges + 1 final email in your tone
- Staggers send times naturally
- Tracks engagement in its workspace
- Flags hot replies; auto-archives dead leads
You request:
"Prepare monthly performance emails for my top 15 clients and suggest times for a 30-minute check-in next month."
Clastines delivers:
Pulls the latest metrics/notes from your tools & files, drafts client-specific updates in your style, proposes 2–3 call slots that fit both calendars, drafts invites and follow-ups for no-shows, and files reports and emails back into the right client folders.
Key Steps:
- Pulls latest metrics from tools & files
- Drafts client-specific updates
- Proposes 2-3 call slots per client
- Drafts invites and follow-ups
- Files everything in client folders
You request:
"Triage my inbox every morning. Summarise, draft key replies, and schedule anything that needs a call."
Clastines delivers:
Summarises yesterday's inbox into a 2-minute brief, drafts replies for clients, investors, partners in your tone, spots anything that needs a call and proposes slots, updates its own task list for follow-ups and deadlines, and shows you a short 'review & approve' queue instead of 200 emails.
Key Steps:
- Summarises yesterday into 2-minute brief
- Drafts replies in your tone
- Identifies calls and proposes slots
- Updates task list for follow-ups
- Shows short review queue, not 200 emails
