Free AI tools for small business: 9 that are actually useful

Search for free AI tools and you get lists of a hundred apps, most of them free trials in disguise. If you run a small business in Ontario, you do not need a hundred. You need a few that save real hours on the jobs you already do: writing emails and posts, taking notes on calls, keeping your calendar sane, and making a decent graphic or short video.

Below are nine tools with a genuinely free plan. For each one we checked the vendor's own pricing or help page on October 14, 2026 and wrote down exactly what the free tier includes. Free plans change often, so treat this as a snapshot and check the page before you rely on a limit.

Free AI tools for small business: 9 that are actually useful at a glance — the short version.

Everyday assistants: Gemini, Microsoft Copilot and Claude

A general AI assistant is the one free tool almost every business owner will use daily: drafting a reply to a tricky customer email, turning rough notes into a job description, or explaining a supplier contract clause in plain English.

• Google Gemini. Google's plans page lists the free tier at 0 $CA a month with a Google Account. It includes access to the Flash-Lite model, image generation and editing, Deep Research, Gemini Live, Canvas, Gems, limited access to the Flow creative studio and 15 GB of storage across Gmail, Drive and Photos. Good for: research, first drafts and quick images if you already live in Gmail.
• Microsoft Copilot. Microsoft's support article says Copilot is available at no cost for chat, real-time answers based on web search and webpage summaries in Edge. Sign-in is not required, but signing in with a personal account adds chat history, image creation, longer conversations and voice. Copilot inside the Word and Outlook desktop apps belongs to the paid plans. Good for: Windows and Edge users who want answers with web results.
• Claude. Anthropic's pricing page lists the free plan as including chat on web, desktop and mobile, web search, file creation, memory across conversations, app connections and Artifacts, with up to five projects and voice mode. Good for: longer writing, editing and summarizing documents.

ChatGPT also has a free tier, but its pricing and help pages blocked our checker today, so we have left its limits out rather than guess.

Writing polish: Grammarly

For a business that writes a lot of quotes, emails and listings, a checker that catches mistakes before a customer does is worth having. Grammarly's plans page says the Free plan corrects spelling and grammar, shows your writing tone, and includes 100 AI prompts a month for generating text. Tone adjustment, full-sentence rewrites, and AI-text and plagiarism detection are on paid plans.

Who should not bother: if you already draft everything in one of the assistants above and rarely send long emails, the browser spell-check may be enough.

Meeting notes and transcription: Otter and Fathom

If you spend your week on client calls, AI notes can save you writing them up afterwards. Two free plans stand out:

• Otter. The Basic plan includes 300 minutes of transcription per user per month, shared across meetings, recordings and imports, with a maximum of 30 minutes per conversation. You also get three lifetime imports of pre-recorded audio or video files. Good for: short calls and voice memos.
• Fathom. Fathom's pricing page describes its free plan as free forever, with unlimited recordings and transcriptions, instant AI call summaries, a choice of bot-free (in beta) or bot capture, and clips, playlists and search across calls. Good for: owners who are on video calls most days and run past 30 minutes.

Before you record anyone, tell them. The Office of the Privacy Commissioner says an organization must tell the customer that it is recording, clearly state the purpose and obtain consent. This is general information, not legal advice.

Scheduling: Reclaim, and why Calendly's free plan is not AI

Reclaim plans your week around your meetings. Its free Lite plan is listed as free forever for one user, with five AI agents (Focus Time, Habits, Buffer Time, Smart Meetings and Meeting Quality), a one-week scheduling range, one calendar sync, one scheduling link and limited integrations such as Google Tasks, Slack, Zoom and Google Meet. Good for: protecting time for quotes, bookkeeping or site visits so meetings do not eat the whole day.

Calendly is still a fine free booking page. Its pricing page lists one event type, one calendar connection and a customizable booking page on the free plan, but its AI assistant and Notetaker are only on paid plans. Do not pick it expecting AI.

Design and video: Adobe Express and Descript

For social posts, flyers and short clips, two free plans are worth a look:

• Adobe Express. The pricing page says the Free plan includes access to 100,000+ static and video templates, 5 GB of storage, and limited generative AI credits and assets, with some AI tools allowing free daily generations. Good for: quick branded graphics without a designer.
• Descript. Descript's Free plan gives you text-based video editing with 60 media minutes a month, 100 AI credits as a one-time allowance, 720p export and 5 GB of storage. Free exports carry a watermark. Good for: trying out editing a talking-head video by editing its transcript.

Two common picks did not make the list. CapCut's pricing page lists free templates and basic editing on its free plan but no AI features; AI credits start on Pro at CAD 33.99 a month. Canva's pricing pages blocked our checker today, so we could not confirm its current free AI limits.

What not to paste into a free AI tool

Free tools are tempting places to paste a customer complaint, a spreadsheet of client names or a patient note. Stop and think first. The Office of the Privacy Commissioner of Canada's principles for generative AI say these tools do not sit outside privacy law, and that where possible you should use anonymized or de-identified information in prompts instead of personal information. Sensitive or confidential details should only go into a prompt where that is authorized.

In practice: replace names, phone numbers, addresses and account numbers with placeholders such as "Customer A", keep health and financial details out entirely, and read each tool's privacy settings before you start. PIPEDA applies to private-sector organizations that handle personal information in commercial activities, and Ontario businesses are generally covered, so using a free tool does not change your obligations. This is general information, not legal advice.

The bottom line

You can cover most small-business AI needs for $0: one assistant (Gemini, Copilot or Claude), Grammarly for polish, Otter or Fathom for call notes, Reclaim for your calendar, and Adobe Express or Descript for visuals. The catch is the limits: minute caps, one-time credits, watermarks and a one-week scheduling window. Start with the one task that eats the most of your week, use the free plan for a month, and only pay when you hit a limit that actually costs you time.
