When you’re building your business alone, here are 10 underrated tools for solo marketers.
Gumloop — Zapier With an AI Brain
Think of Gumloop as what Zapier would look like if it were built in 2026 instead of 2012. It connects any major AI model — ChatGPT, Claude, Grok — directly to your existing tools and workflows without writing a single line of code. You can build automated workflows for competitor research, content creation, social sentiment analysis, and reporting, all in a clean drag-and-drop interface. It even includes access to premium AI models out of the box with no separate API keys required.
SparkToro — Know Exactly Where Your Audience Lives
SparkToro tells you what your target audience actually reads, watches, listens to, and follows online — without surveys, focus groups, or guesswork. For solo marketers trying to figure out where to spend their limited time and budget, it’s one of the most useful and most underused tools available. One SaaS team used it to discover their ideal buyers spent the majority of their online time in three specific industry newsletters — and newsletter sponsorships became their top acquisition channel within 90 days.
Kling AI — Professional Video Ads Without a Production Team
Kling AI is the tool behind many of the AI video ads that are quietly crushing it on social platforms right now. It functions as a full AI creative studio for generating video content from text prompts or images, with video models that keep getting sharper. The workflow top performance marketers are using: Claude for scripts, Kling AI for video snippets, ElevenLabs for voiceover, and Topaz Labs for final enhancement. The whole production stack costs less per month than a single hour of agency video work.
NotebookLM — Your Personal Research Assistant
Google’s NotebookLM is one of the most genuinely useful free tools released in recent memory, and most marketers have barely touched it. You upload your own documents, PDFs, competitor content, or research links, and it answers questions exclusively based on those sources — no hallucinations, no made-up stats. It also automatically generates a listenable podcast-style audio summary from whatever you feed it, which makes it extraordinary for processing large amounts of research quickly.
Perplexity Pro — Research That Actually Cites Its Sources
Perplexity Pro combines AI reasoning with live web search and real source citations, making it a dramatically more reliable research tool than any standard AI chatbot for marketers who need accurate, verifiable information. It’s especially useful for market research, competitor analysis, trend spotting, and fact-checking before anything goes to print. At roughly $20 a month, it’s one of the highest-value subscriptions available for a solo marketer who does serious research work.
ElevenLabs — Studio-Quality Voice for Everything
ElevenLabs produces AI-generated voiceovers so realistic that most listeners cannot tell the difference from a professional recording. For solo marketers producing video content, podcast ads, course material, or any audio-driven marketing, it removes the need for a recording setup, a voice actor, or hours of editing. You can clone your own voice for consistent brand audio or choose from hundreds of available voices across dozens of languages — which pairs perfectly with the global content opportunities opening up right now.
Exploding Topics — Find Trends Before They’re Trends
Exploding Topics surfaces emerging keywords, products, and topics months before they hit mainstream awareness — making it an extraordinary tool for content marketers and newsletter operators who want to be the first voice in a conversation rather than the hundredth. The free version gives you enough to be genuinely useful, and the Pro version lets you filter by category, growth rate, and time horizon so you can build an editorial calendar around topics that are about to matter rather than ones that already do.
Fathom — Meeting Notes That Actually Capture Everything
Fathom records, transcribes, and summarizes your calls and meetings automatically — then delivers clean, organized notes without a bot visibly sitting in your meeting making everyone uncomfortable. For solo marketers juggling client calls, sales conversations, and strategy sessions, it eliminates the note-taking tax and lets you be fully present in the conversation. The free plan includes unlimited recordings and transcriptions, which makes it one of the easiest productivity upgrades available at zero cost.
AI Peekaboo — See How AI Describes Your Brand
As more buyers turn directly to ChatGPT, Gemini, and Perplexity instead of clicking through search results, knowing how those AI systems describe your brand — or whether they mention you at all — has become critically important. AI Peekaboo tracks your brand’s visibility and sentiment across five major AI platforms, distills it into a single AI Visibility Score, and shows you exactly which sources each AI model draws from when generating answers about your category. For solo marketers building authority in a niche, this is the new rank tracking.
Beehiiv — The Newsletter Platform Built for Growth
Beehiiv was built by the team behind Morning Brew and it shows — it’s the only newsletter platform designed from the ground up with monetization and growth as first-class features rather than afterthoughts. It takes zero percent of your subscription revenue, includes a native ad network, referral programs, advanced segmentation, and analytics that tell you exactly what’s working. For solo marketers serious about building a newsletter business rather than just a hobby, it’s the most complete platform available at any price point.
I hope you will find these tools helpful in your online marketing journey.
