1. GrammarlyGO – Your AI Writing Assistant for Effortless Writing

GrammarlyGO (by Grammarly) is an AI-powered writing assistant that helps you compose, rewrite, and brainstorm text quickly. Integrated into the popular Grammarly app/extension, it not only corrects grammar but also generates content. For example, if you’re stuck replying to a long email or drafting a report, GrammarlyGO can suggest a full reply or a paragraph in your chosen tone. It analyses the context of your writing to draft thoughtful, tailored text, taking into account your voice and intent . This means you can spend less time writing emails or documents, and more time on higher-value tasks.

How it boosts productivity: GrammarlyGO accelerates writing tasks. You can instantly generate email replies based on an email’s context or get ideas to kickstart a blog post. It’s like having a smart writing partner that provides suggestions on the fly. For instance, if you need a friendly yet professional response to a client, GrammarlyGO will draft one with the appropriate tone in seconds. This saves you from typing from scratch or worrying about phrasing.

Key features (Free Tier):

• Compose and rewrite text with AI directly in any text field (emails, documents, social media).
• Customize the tone or intent (e.g., make text more formal, friendly, shorter, etc.).
• 100 AI prompts per month on free plan (renews monthly) for generative tasks – plenty for occasional use.

2. Bing Image Creator – Free AI Image Generation by Microsoft

Example image generated by Bing Image Creator (DALL-E 3) – a photorealistic mountain scene created from a text prompt.

Need custom visuals in a snap? Bing Image Creator is a free AI tool that turns your text descriptions into images. Powered by OpenAI’s latest DALL-E 3 model, it can produce anything from presentation graphics to concept art simply by typing what you imagine. For example, you could write “a modern office workspace with futuristic AI assistants” and Bing will generate a set of images matching that description. The tool is integrated into the Bing search platform, making advanced image generation accessible to anyone with a browser.

How it enhances productivity: Instead of scouring stock photo websites or waiting on a designer, you can create on-demand images for your needs. This is a boon for content creators, marketers, students, or entrepreneurs who need quick visuals. Users have leveraged Bing Image Creator for tasks like making illustrated story scenes, social media post graphics, YouTube thumbnails, and even unique slide backgrounds . It’s a time-saver when you need a specific image that doesn’t exist publicly – just describe it and get multiple AI-generated options in seconds.

Key features:

• Unlimited image generation for free (no subscription required) – new users get a few “boosts” for faster rendering, but even after those are used, it still generates images at a slightly slower pace .
• Powered by DALL-E 3, a state-of-the-art image model, which means outputs are high-quality and follow prompts closely (even complex scenes or specific art styles).
• Simple interface: just enter a prompt. You can refine results by adjusting the prompt or trying again. No design skills needed.
• Images include a subtle digital watermark for transparency (ensuring ethical use of AI images , but this is invisible in normal viewing and doesn’t detract from the image.

Platforms: Bing Image Creator is browser-based. You can access it on the web (on Bing’s site) from any device. It’s also integrated into the Microsoft Bing Chat (in Creative mode) if you prefer a chat interface. No installation needed – works on PC, Mac, or mobile browsers.

3. BeforeSunset AI – The AI-Powered Daily Planner and Scheduler

BeforeSunset AI is a smart day planner that uses AI to help you organize your tasks and time. Think of it as a digital personal assistant that takes your to-do list and automatically arranges it into an optimal schedule. You input your tasks (and import your calendar events), and with one click, BeforeSunset’s AI schedules your day – ordering tasks by priority, setting time blocks, and even suggesting focus sessions. It’s more than a to-do app; it actively helps plan your day for maximum productivity .

How it enhances productivity: Planning can be time-consuming. BeforeSunset AI eliminates the manual work of deciding when to do what. For example, if you list tasks like “Finish report, Team meeting at 3PM, Call client, 1 hour coding practice,” the AI will map these onto your day’s timeline around the fixed 3PM meeting, maybe scheduling the report in the morning when you’re fresh and the call right after the meeting. It ensures you don’t overlook breaks or overcommit, promoting a balanced schedule. By automating routine planning, it frees you to focus on executing tasks. Users overwhelmed by endless to-do lists find it helpful – it brings order to chaos by creating a realistic, optimized plan for the day .

• Focus Oasis Mode: A built-in focus mode (with Pomodoro timer, ambient sounds, etc.) to help you stay on track during the scheduled focus sessions .
• Integration: Syncs with calendars (so it knows your events) and lets you take notes within the app. It automatically carries over unfinished tasks to the next day (no task left behind). This all-in-one approach means you spend less time switching between calendar, to-do app, and notes.

Platforms: Available on Web, iOS, and Android . You can plan your day on the desktop web app and then check tasks or get reminders on the mobile app. The mobile app is handy for adding tasks on the go and staying synced.

Sign-up: Yes, you need to sign up (free) to save your plans. The free version offers core features so you can use AI planning at no cost. For power users, a Pro plan (~$8–10/month) unlocks unlimited AI usage and other advanced features , but many users find the free tier sufficient to start.

4. Otter.ai – AI Meeting Transcripts and Summaries on Autopilot

Otter.ai creates AI-generated meeting notes, with summaries, action items, and outlines for easy review.

Tired of taking meeting notes or missing details in long discussions? Otter.ai is an AI-powered transcription service that joins your meetings (virtual or in-person) and produces live transcriptions and summaries. Essentially, Otter.ai acts as a virtual notetaker: it listens to meetings or lectures, transcribes everything being said, and even highlights key points and action items. With a free Otter account, you get a generous allowance of transcription each month – making it a must-have productivity tool for anyone who attends a lot of meetings, classes, or interviews.

How it enhances productivity: Otter saves you from manual note-taking, allowing you to focus on the conversation. After the meeting, you instantly have a written record (no need to rely on memory or scribbles) and an AI-generated summary. This means you can quickly review what was discussed or share the notes with teammates who couldn’t attend. For example, if you had a one-hour team call, Otter can provide a summary highlighting decisions made and tasks assigned, plus a full transcript you can search later. It’s incredibly useful for students as well – record a lecture with Otter and get the notes and summary to study from. By eliminating the need to write notes, you reclaim time and ensure accuracy (no more “what was that figure mentioned?” moments – just search the transcript).

Key features (Free Plan):

• Live transcription and recording: Otter’s AI transcribes speech in real time (in English, and even French or Spanish) and identifies speakers. You see text appear as people talk. After the session, you can play back audio aligned with the transcript.
• Automated summaries and highlights: The AI meeting assistant not only transcribes but also generates a summary of the conversation and pulls out action items or key themes . This makes reviewing a 1-hour meeting possible in a minute.
• Meeting integration: Otter can automatically join Zoom, Google Meet, or Microsoft Teams meetings on your behalf as a virtual participant . It will record and transcribe the call for you (with all participants informed). No need to remember to hit record.
• Collaboration: You can share transcripts with teammates and even collaboratively highlight or comment within Otter. The free plan allows adding some team members to your workspace for shared meeting notes 

Limitations of free tier: The Basic (free) plan gives 300 transcription minutes per month, with up to 30 minutes per conversation . In practice, that could cover, say, ten 30-minute meetings a month. You can also import up to 3 audio/video files for transcription (lifetime limit on free). For many individuals, this is enough; if you need more, Otter’s paid plans increase these limits.

Platforms: Web and Mobile apps (iOS/Android). You can use Otter on a web browser for uploading files or live recording. The mobile app is handy for recording in-person meetings or lectures. It also integrates with Zoom (via an add-on) and has a Chrome extension for Google Meet. All data syncs across devices (start recording on phone, view transcript on laptop later).

Sign-up: Yes, you need to create an Otter.ai account (free). Once signed up, you can immediately start recording or invite the Otter assistant to your online meetings.

5. Gemini – AI Assistant with Google Workspace Integration

Google Bard – recently upgraded with Google’s Gemini AI model – is a conversational AI assistant that can help with a bit of everything: writing, research, coding, summarizing, and notably, it connects with your Google apps. Bard is Google’s answer to ChatGPT, and it’s freely available. What makes Bard stand out is how it can pull information from your Gmail, Google Docs, Drive, and other services (with your permission) to give you extremely contextual, useful help. This means you can ask Bard to summarize a long document stored in your Google Drive, or draft a response to an email by analysing the email’s content – tasks that blend AI smarts with your personal data (privately).

How it enhances productivity: Bard serves as an on-demand research buddy and creative helper. Need to draft a quick summary of a lengthy report? Paste the text (or if it’s in your Google Docs, let Bard fetch it) and it will summarize the key points. Unsure how to analyse some data in a spreadsheet? Bard can interpret a snippet of it or provide formulas. It’s also great for idea generation – ask for social media post ideas, or coding assistance. A powerful scenario is leveraging Bard’s new integration: for example, “Summarize the quarterly sales report from my Drive and draft an email to the team with the highlights”. Bard can do that in one go: find the file, pull the key stats, and produce a concise email draft. Similarly, if you’re job hunting, you could tell Bard to look at your CV in Drive and a job description, then “help me write a cover letter highlighting relevant experience” – a huge time-saver (Google Bard Now Integrates With Google Apps). By tying into the Google ecosystem, Bard cuts out the copy-paste dance and directly uses your content to give answers, making you far more efficient in managing information.

Key features:

• Generative AI chat: You can converse with Bard in plain English (and 40+ other languages) to get answers, explanations, or creative content. It can write code, translate, answer questions, and more. People use Bard for tasks like planning trips, drafting product descriptions, or explaining complex topics in simpler terms .
• Google Apps Extensions: This is Bard’s killer feature. With your consent, Bard can pull data from Gmail, Google Calendar, Docs, Drive, Maps, YouTube, etc. It will display relevant info from your Google apps to enrich its responses . (All your data stays private and isn’t used for training.) This effectively makes Bard a unified interface to query your personal information cloud – extremely handy for summarizing emails or documents.
• “Google It” Verification: Bard provides a button to quickly fact-check its answer against Google Search . This helps you trust but verify important answers, ensuring accuracy.
• Continuous conversations and context: Bard remembers what you’ve asked in a session, so you can refine requests. (E.g., “Actually, make that summary more formal” or “Now translate that into French.”) You can also share chat links, and others can continue the conversation from that point.

Platforms: Browser-based (web) – just visit the Bard website. There’s no dedicated mobile app yet, but the web interface works on mobile browsers as well. Bard doesn’t require any installation. (Note: On Android devices, Bard is gradually being integrated into the Google app/assistant.) Also, Chrome users can pin Bard for quick access. Since it’s web-based, it’s accessible anywhere you have internet.

Sign-up: You need to log in with a Google account (which most people have). Bard is free to use. There’s no waitlist as of 2025 – it’s open to all users globally. Just go to the site and start chatting.
