Good fit for

Organisations standardised on Word, Excel, Outlook and Teams.

Look elsewhere if

Small teams that want a low-cost assistant without extra licences.

How it scored

  • Work quality: 70/100. Capable at drafting and summarising, but output quality depends on how well organised your files are.
  • Work integration: 90/100. Works inside Word, Excel, Outlook and Teams and grounds answers in your organisation's data.
  • Value: 40/100. An add-on from $21 per user a month on top of a Microsoft 365 subscription.

  • Expert & User Ratings: 70/100. Recommended by a couple of expert reviewers.

Our verdict

Copilot ranks fourth because its reach across Word, Excel, Outlook and Teams is excellent. The add-on cost on top of Microsoft 365 lowers its value, and results depend on how tidy your files are.

  • Grounds answers in your organisation's data
  • Enterprise admin and compliance controls
Cons
  • Business add-on from $21 per user a month on top of Microsoft 365

  • Complex licensing
Things to know before you buy:
  • It is a business add-on from $21 per user a month on top of an underlying Microsoft 365 subscription.
  • Microsoft 365 suite prices have risen, so check the total per-user cost, for example Business Standard moved from $12.50 to $14.50 on July 1, 2026.
  • Licensing can be complex, and answers depend on your files being well organised.
  • Price change: Jan 2025: consumer Microsoft 365 plans rose by $3 a month with Copilot bundled. Jul 1, 2026: business suites rose (for example Business Standard $12.50 to $14.50).
  • Outage: No Copilot-specific major outage found.

Comparison Table

How to Choose

Start with the tools your team already uses

An assistant that sits inside your email, documents and calendar saves copying and pasting. Teams on Google Workspace or Microsoft 365 will usually get the most from the assistant built into that suite, while teams on Notion may prefer Notion AI. If your work is spread across many apps, a standalone assistant with file uploads and connectors can be more flexible.

Match the assistant to the kind of work

Some assistants are all-rounders for writing, research and analysis, while others are narrower: Perplexity is built around sourced web research, and DeepSeek is aimed at coding and maths. Write down your three most common tasks and try each assistant on those before you decide.

Compare business plans, not just consumer prices

Headline prices often describe individual plans. Business and enterprise plans add admin controls, shared workspaces and sometimes different data-handling terms, and some assistants are sold as an add-on on top of an existing subscription. Add up the full per-user cost.

Read the data-handling terms for work use

Check whether your inputs are used to train models on the plan you are buying, where data is stored and what admin controls exist. Ask your IT or legal team to review the terms for the plan you plan to roll out rather than the free tier.

Pilot with a small group first

Give a handful of people a free tier or trial and a shared list of real tasks. Compare accuracy, tone and how often output needs correcting. Assistants can state wrong information confidently, so build in a check for anything customer-facing.

Plan for tidy data if you want company-wide answers

Assistants that search your files, mail and meetings can only be as useful as the material they can reach. Clear folder structure and up-to-date documents make a noticeable difference, so budget a little time for clean-up before a wider rollout.

Frequently Asked Questions

What is an AI workplace assistant?

It is a chat-based tool that helps with everyday work such as drafting emails, summarising documents, analysing data and researching topics. Some sit inside office apps, while others are standalone assistants you open in a browser or app.

Which AI assistant is best for teams on Google Workspace or Microsoft 365?

Google Gemini works inside Gmail, Docs, Sheets and Drive and is bundled into Workspace business plans. Microsoft 365 Copilot works inside Word, Excel, Outlook and Teams and is sold as an add-on to a Microsoft 365 subscription.

Are there free AI assistants that are good enough for work?

Several have free tiers, including Gemini, ChatGPT, Claude, Mistral Le Chat, Perplexity, DeepSeek and Meta AI. Free tiers usually have usage limits and fewer features, and they lack the admin controls of business plans.

Which assistant is best for research with sources?

Perplexity shows citations by default and can search uploaded files, which makes it quick to check where an answer came from. ChatGPT also offers a deep research mode. Reviewers note that citations should still be checked against the original pages.

How much do AI assistants cost per user?

Individual paid plans on this page start from about $5 to $20 a month, and business plans are priced per user and vary by vendor. Microsoft 365 Copilot's business add-on starts at $21 per user a month on top of a Microsoft 365 subscription. Check each vendor's pricing page for current rates.

How We Evaluated

Every Flickthru ranking follows the same five-step process, applied the same way to every product on the page.

  1. Market scan: We gathered the 14 platforms recommended across current expert reviews, buyer guides and verified-user ratings, then shortlisted the 10 that best fit this category and offer their own built-in AI.
  2. Evidence gathering: For each shortlisted product we collected features, plans and current pricing from the vendor, alongside the strengths and weaknesses reported in recent expert reviews.
  3. Risk checks: We checked every product for recent price changes and service reliability. Anything relevant is summarised in the product’s Detailed Analysis and reflected in its score.
  4. Scoring: Each product is scored against the five criteria in our Evaluation Methodology using the same rules for every product, and the Flickthru Score out of 100 combines them. Work quality, the main job these tools do, counts most. Value is judged on what the paid plans deliver for their price. Each product’s Detailed Analysis explains how it scored on every criterion.
  5. Editorial independence: Rankings are decided by Flickthru’s editorial process alone. Placement cannot be bought.

This ranking was last updated in September 2026. This page was researched and drafted with the help of Claude, an AI assistant made by Anthropic, which is one of the companies ranked here. We applied the same criteria to every assistant.
