Daily planning & task extraction from mail, chat and notes

Employees let an AI assistant pull to-dos and deadlines out of their e-mails, chats and meeting notes, push them into the task list and propose a realistic plan for the day.

Quick win: proven, manageable effort, first results within weeks, low regulatory risk.

Parts needed to run it yourselfAgents & automationLanguage model

Commitments hide in threads: "Can you send me the offer by Friday?" sits in message 14 of a mail chain, a chat reply or a line of meeting minutes. An AI assistant reads these sources, proposes tasks with due dates and a link back to the origin, and suggests a day plan. The employee confirms, edits or discards each proposal. Typical benefit: fewer dropped follow-ups and a faster start into the day, with setup in days, not weeks.

Problem & value

  • Today: people keep to-dos in their head, flag mails, copy chat lines into a notebook or Excel list. Deadlines are missed when a thread is long or a person is out of office.
  • AI value: language models are good at spotting requests, owners and dates in free text and at turning them into a short, actionable title. Planning (ordering by deadline and effort) is a light second step.

Variants

  • Microsoft 365: Copilot turns a mail into a task and the Planner agent can create tasks from Outlook and Teams content into "My Tasks" or shared boards (availability depends on licence and admin settings).
  • Google Workspace: Gemini in Gmail and Google Tasks for the same pattern.
  • No-code flow: n8n or Power Automate reads flagged mails or a notes folder, calls an LLM and writes tasks to Planner, Nextcloud Tasks or Vikunja.

How it works

  1. mail / chat / notes
  2. (flag or trigger)
  3. LLM extracts: action, owner, due date, source link
  4. human reviews proposal
  5. task list (To Do, Planner, Nextcloud, Vikunja)
  6. morning prompt: open tasks + calendar
  7. proposed day plan
  8. human adjusts
  • Human-in-the-loop: every task is a proposal; nothing is created silently on behalf of others and nothing is sent. Due dates left blank by the model must be set by the person.
  • Trigger choice: opt-in (user flags a mail or presses a button) is safer and more accepted than a bot that scans every mailbox.

Data preparation

Which data: the user's own mailbox, chats, calendar and notes. No training data is needed. - Gaps: relative dates ("next Friday") without a reference date, mixed German/English threads, notes scattered across OneNote, Word and paper, and no single task list. - Steps (typically 2 to 8 hours per team): agree on one task tool; pass the current date and time zone in the prompt; define a folder or flag for opt-in sources; set a naming scheme (verb first, e.g. "Send offer to Müller"); exclude confidential mailboxes (HR, works council, management board) by access rules.

Implementation paths

Which path for whom

  • SMB: A. Most SMBs already have Microsoft 365 or Google Workspace; the built-in assistant is a mature, standard product. Use B/C only if you lack licences.
  • Enterprise: A. A commodity function; use the suite's assistant and govern it centrally.
  • Developer: C. Self-built n8n flow with a local model, full control and no vendor data flow.
  • Private: C. Local apps (Ollama or LM Studio with a notes app) keep private mail out of the cloud; A also works.

Path A — Buy (off-the-shelf)

  • Microsoft 365 Copilot with Outlook, Teams, To Do and Planner (the Planner agent). Check the EU Data Boundary and the "Flex Routing" setting in the admin centre: Microsoft documents that it can allow model inference outside the EU Data Boundary at peak load; reports say it was enabled by default for EU/EFTA tenants from April 2026 (verify in your admin centre), so decide on it deliberately.
  • Google Workspace with Gemini and Google Tasks.
  • Right choice when the suite is already licensed and mail/chat data may be processed by the suite vendor under your existing contract. Seat cost is the main driver; we have no verified current EU price here, so check the vendor price list.

Path B — Build on cloud APIs

  • Power Automate or n8n flow with an EU-hosted LLM API (e.g. Mistral, Azure OpenAI in an EU region, Aleph Alpha) extracting tasks into Planner or Vikunja.
  • Worth it when staff use mixed tools or you want the same flow for a shared inbox. Effort: 1 to 3 days.

Path C — Self-host (open source)

  • Stack: n8n (self-hosted) + Ollama with a small instruction model (7 to 14B class) + Nextcloud Tasks, Vikunja (AGPL, REST API, CalDAV) or Paperless-ngx for notes. All EU-hostable.
  • Hardware: HW1 is enough for short texts with a small model; HW2 gives faster, better German. Effort: 2 to 5 days plus light upkeep.
  • Choose C for sensitive mail content or when the same n8n/Ollama platform serves several AUTO use cases (Baukasten effect).

Path D — Custom training

Not needed; prompting is enough.

State of the art (2026)

  • Suite assistants now offer task creation from mail and chat, and agentic planners that write into Planner. Availability varies by licence and tenant settings.
  • Current LLMs extract explicit requests reliably, but struggle with implicit commitments, sarcasm, long threads with several owners, and relative dates.
  • Failure modes: hallucinated deadlines, tasks assigned to the wrong person, missed items in long threads, duplicate tasks from repeated runs, and tasks created from phishing mails (prompt injection via mail content, see GUIDE-013).

Shared resources & combinations

Effort, cost & KPIs

  • A: 1 to 3 days to enable, pilot and write a short guideline; cost is licence seats.
  • B: 1 to 3 days build, small API cost, low running effort.
  • C: 2 to 5 days build, server cost (existing HW1/HW2 may suffice), a few hours per month upkeep.
  • KPIs: share of proposed tasks accepted without edits, missed-deadline count before/after, minutes spent on morning triage (self-reported), number of false or duplicate tasks per week.

People & change

  • Works council: yes, likely. An assistant reading mail and chat can log user behaviour, and the BAG holds objective suitability for monitoring is enough for §87(1) no. 6 BetrVG. Also inform it early under §90(1) no. 3 and consider an expert under §80(3). Agree on: opt-in, no evaluation of individuals' task lists by managers, no use for performance review. Public sector: Personalrat.
  • DPO: involve early. Mail and chats contain personal data of third parties; a DPIA is usually not required for a purely personal, opt-in helper but check if processing is systematic or outside the EU; an AVV (Art. 28 GDPR) is needed with every provider (GUIDE-005).
  • AI literacy: support staff with a 1 to 2 hour intro on checking proposals and what not to feed in (AI Act Art. 4, GUIDE-006).
  • Rollout: pick a pilot group of 5 to 10 volunteers, name an AI champion, communicate that managers cannot see individual suggestions, collect feedback after 4 weeks (GUIDE-008, GUIDE-009, GUIDE-004).

Risks, regulation & compliance

  • EU AI Act: minimal risk as a personal productivity helper. Do not use it to rate employee performance; that would shift the picture toward Annex III. Art. 50 transparency applies only if text is sent to third parties as AI-generated chat (not here). See GUIDE-014.
  • GDPR: third-party personal data in mails; limit sources, set retention, document in the processing register. Check where processing happens (EU Data Boundary, Flex Routing).
  • Security: prompt injection through incoming mail; keep the assistant read-only on mail, with write access only to the task list.

Getting started

  1. Choose one task tool and one pilot team of 5 to 10 volunteers.
  2. Check licences and admin settings (Planner agent, EU data processing setting) with IT and the DPO.
  3. Brief the works council and agree the opt-in rules in writing (see GUIDE-004).
  4. Run a 4-week pilot with the prompt pattern above; track acceptance rate and false tasks.
  5. Decide go/no-go; if A falls short, test an n8n + Ollama flow on existing hardware.
