The tool stack for writing blog posts changed less between 2022 and 2026 than the workflow did. AI assistants now handle first drafts and keyword brainstorming, which makes the remaining tools — the ones that organize, edit and polish — more valuable, not less. This list keeps the five that survived the shift and notes where AI fits around them.
Quick Answer: Trello for organizing your editorial calendar, Google Keyword Planner for finding what people search, Thesaurus.com for word choice, Hemingway Editor for tightening prose, and Grammarly for grammar and typos. AI assistants slot in at the drafting stage before all of these.
1. Trello — for the editorial calendar
Most blogs don't fail at writing; they fail at publishing consistently. Trello's boards fix that cheaply: one card per post idea, lists for stages (idea → drafted → edited → scheduled → published), due dates and a checklist per card for the unglamorous steps (add images, internal links, meta description).
Notion has taken some of Trello's audience, and if you already live in Notion, its kanban views do the same job. Trello's advantage is that it stays boring in the best way — free tier, no setup ceremony, works the same in 2026 as it did in 2016.
Best for: anyone publishing on a schedule with more than one writer (or a forgettable memory).
2. Google Keyword Planner — for finding the topic people actually search
Writing about what interests you is a hobby; writing about what people search for is blogging. Google Keyword Planner (free with a Google Ads account, no ads required) shows search volume ranges and related terms for any seed topic, which is how you discover that "how to fix" beats "best ways to repair" before you write a word.
Pair it with Google Search Console on your own site — the queries you already rank for on page two are the cheapest articles you'll ever write.
Best for: deciding what to write next, not how.
3. Thesaurus.com — for word choice
The humble entry of the list. Repetitive wording is the most visible flaw in drafts: the same adjective three sentences in a row, "use" five times per paragraph. Thesaurus.com remains the fastest way out, with the usual warning that a thesaurus suggests — you still have to pick the word a human would say.
Best for: revising, not drafting.
4. Hemingway Editor — for tightening prose
Paste a draft into Hemingway Editor and it highlights long sentences, passive voice, adverbs and needlessly complex words, with a readability grade at the end. It's a blunt instrument — good writing isn't always grade 6 — but it's exactly the right editor for blog prose, where clarity beats flourish. The web version is free; the desktop app is a one-time purchase.
Best for: the second draft, when your sentences have grown lazy.
5. Grammarly — for grammar and typos
Grammarly's free browser and web-app checking catches the errors that embarrass: misspellings, subject-verb agreement, punctuation. The paid tiers add tone suggestions and rewrites. In 2026 every major word processor bundles some of this natively, and AI assistants do line-editing too — but a dedicated grammar checker catches things both you and the chatbot will miss because it's checking, not generating.
Best for: the last pass before publishing.
Where AI fits in 2026
The honest update since the original version of this list: AI assistants (ChatGPT, Claude, Gemini and friends) now do the drafting stage — outline, first pass, headline variations, meta descriptions. Two rules keep that from backfiring:
1. Facts come from sources, not the model. AI drafts confidently invent statistics; verify every claim you publish.
2. The tools above are the human layer. Outline in Trello, verify keywords in Planner, then edit what the model produced with Hemingway and Grammarly. Publishing unedited AI output is both a quality problem and, on Google, a scaled-content risk.

FAQ
What is the best tool for writing blog posts?
There's no single one — the job has stages. Trello organizes, Keyword Planner finds the demand, Hemingway and Grammarly clean the draft. If you only add one tool in 2026, make it an AI assistant for drafting, with Hemingway as the counterweight that keeps the prose human.
Are free tools enough for blogging?
For most blogs, yes. Every tool in the table above does its core job free. Paid tiers earn their cost when you write daily or publish for clients — Grammarly Premium's tone checks and a paid AI subscription are the two upgrades with real returns.
Is AI good for writing blog posts?
For outlines, first drafts and beating the blank page, yes — with verification. For final drafts, no: unedited AI text reads generic and risks search penalties on scaled content. The working pattern is AI draft, human rewrite, tool-checked polish.
How do I find keywords for free?
Google Keyword Planner with a Google Ads account, Google Search Console for queries your site already ranks for, and Google's own autocomplete plus the People Also Ask boxes. That combination covers most blogs' research needs without a subscription.
