Artificial intelligence has moved from a corporate luxury into something genuinely available to everyone. The free tier of most major AI tools today would have cost thousands of dollars just a few years ago. Here is a clear list of what is worth using and why.
1. ChatGPT by OpenAI
The one that started the mainstream AI conversation. ChatGPT handles writing assistance, email drafting, brainstorming, article summarisation, and basic coding help. The free tier runs on GPT-4o mini, which is more than capable for most everyday tasks. No credit card required to start.
Best for: Writing, Q&A, summarising content, generating ideas.
2. Grammarly
Grammar and spell-check have existed for decades, but Grammarly's AI layer goes further. It checks tone, detects plagiarism, improves sentence structure, and makes suggestions based on your intended audience. The free version covers the essentials. The paid version adds deeper tone and style analysis.
Best for: Professional writing, students, anyone sending important emails.
3. Canva AI
Canva has always been the go-to for non-designers who need to produce visual content. The AI features — text-to-image, background removal, smart resize, and design suggestions — make it faster and more accessible than ever. The free tier is genuinely usable.
Best for: Social media graphics, presentations, marketing materials, thumbnails.
4. Otter.ai
Upload or record any audio and Otter transcribes it accurately with speaker identification. Useful for meetings, lectures, interviews, and voice notes. The free plan covers 600 minutes of transcription per month, which is enough for moderate use.
Best for: Meeting notes, lecture transcriptions, interview recordings.
5. Notion AI
If you already use Notion for notes or project management, the AI layer adds the ability to summarise pages, generate outlines, translate content, and rewrite sections. It works inside your existing workspace without switching context.
Best for: Note-takers, students, project managers, content teams.
6. Remove.bg
Single-purpose and excellent at it. Paste any image URL or upload a file and it removes the background instantly. Free for low-resolution output. Useful for product photos, profile pictures, and design work.
Best for: Quick background removal without opening Photoshop.
7. Zapier AI (Free Tier)
Zapier connects apps together and automates workflows. The AI features help you describe what you want to automate in plain language, and Zapier builds the automation for you. The free tier covers 100 tasks per month.
Best for: Automating repetitive tasks between apps you already use.
8. Lumen5
Turn a blog post or a piece of text into a short video. Lumen5 matches your text to relevant visuals and produces a draft video you can customise. Not perfect, but significantly faster than editing video manually for basic content needs.
Best for: Repurposing written content into short-form video.
