Writing

Writing long-form articles

Any frontier chat model drafts well; the difference is how much of your own research and voice you feed it up front.

  1. 1. ChatGPT (GPT-class)Free tier · ~$20/mo

    Strongest all-round drafting and editing

  2. 2. ClaudeFree tier · ~$20/mo

    Best at long documents and holding a consistent voice

  3. 3. GeminiFree tier · ~$20/mo

    Cheapest long-context option with web grounding

Free route

Draft on a free tier, then rewrite the opening and closing yourself — that's where AI text reads flattest.

Watch out

Unedited AI drafts read uniform. Run the result through a detector-style read before publishing.

Code

Writing and debugging code

In-editor assistants beat chat windows for day-to-day work because they see your whole repository.

  1. 1. CursorFree tier · ~$20/mo

    Editor-native, multi-file edits and repo awareness

  2. 2. GitHub Copilot~$10/mo

    Cheapest inline completion inside existing editors

  3. 3. Claude CodeUsage-based

    Best for large refactors and terminal-driven work

Free route

Free chat models handle single-file bugs fine; pay only when you want repo-wide edits.

Watch out

Always run the tests. Confident-looking generated code fails most often on edge cases and auth.

Design

Generating images and graphics

Pick by output style: photoreal, illustration, or text-in-image reliability.

  1. 1. Midjourney~$10–30/mo

    Best aesthetic quality out of the box

  2. 2. Google Imagen / GeminiFree tier · usage-based

    Most reliable legible text inside images

  3. 3. Flux (open weights)Free / hosting cost

    Self-hostable, no per-image licensing worry

Free route

Free tiers are enough for social posts; pay once you need consistent characters or brand style.

Watch out

Check the licence before commercial use, and never generate real people's likenesses.

Video

Editing or generating video

Editing tools save far more time than generation tools for most people.

  1. 1. DescriptFree tier · ~$24/mo

    Edit video by editing the transcript

  2. 2. CapCutFree · ~$8/mo

    Fast captions, cuts and social formats, mostly free

  3. 3. Runway / Veo-class~$15–95/mo

    Actual generated footage for B-roll

Free route

CapCut plus a free transcription model covers most short-form workflows at zero cost.

Watch out

Generated footage still breaks on hands, text and continuity — use it as B-roll, not the hero shot.

Productivity

Meeting notes and transcription

All of these transcribe well; choose on where the notes need to land afterwards.

  1. 1. OtterFree tier · ~$17/mo

    Cheapest reliable transcription with a usable free tier

  2. 2. FathomFree · ~$19/mo

    Strong free plan with action-item extraction

  3. 3. Built-in (Zoom/Teams/Meet)Included

    No extra vendor or consent headache

Free route

Your conferencing tool's built-in recap is free and usually good enough.

Watch out

Recording consent is a legal issue in many regions — announce it every time.

Research

Research with sources

You want citation-first tools, not a chat model recalling from memory.

  1. 1. PerplexityFree tier · ~$20/mo

    Search-grounded answers with inline sources

  2. 2. Gemini Deep ResearchIncluded with paid tier

    Long multi-source reports

  3. 3. NotebookLMFree

    Answers restricted to documents you upload

Free route

NotebookLM is free and the safest option when the sources are yours already.

Watch out

Open every citation. Grounded tools still occasionally attach a real link to a wrong claim.

Data

Spreadsheets and data analysis

Upload the file to a model with a code interpreter rather than asking for formulas blind.

  1. 1. ChatGPT data analysis~$20/mo

    Runs real Python on your uploaded file

  2. 2. Claude with file uploadFree tier · ~$20/mo

    Best at explaining what it did to your data

  3. 3. Sheets/Excel built-in AIIncluded in paid plans

    Stays inside the file you already use

Free route

Paste a sample of 50 rows into a free model and ask for the formula — then apply it yourself.

Watch out

Never upload customer or health data to a consumer tier. Check the retention setting first.

Business

Automating customer support

Deflection rate matters more than model quality — measure it before scaling.

  1. 1. Intercom FinPer-resolution pricing

    Highest out-of-box deflection on help-centre content

  2. 2. Zendesk AIAdd-on per agent

    Best if you already live in Zendesk

  3. 3. Custom RAG botAPI cost only

    Cheapest at volume if you have an engineer

Free route

Start by generating better help-centre articles — that alone cuts ticket volume.

Watch out

Always leave a one-click path to a human. Forced bot loops cost more in churn than they save.

Productivity

Building slide decks

AI is good at structure and first-pass layout, weak at the argument itself.

  1. 1. GammaFree tier · ~$10/mo

    Fastest decent-looking deck from an outline

  2. 2. Canva MagicFree tier · ~$15/mo

    Best template library and brand controls

  3. 3. Chat model + your templateFree

    Free, and keeps your existing house style

Free route

Ask a free chat model for the slide-by-slide outline, then paste it into your own template.

Watch out

Generated decks look samey. Replace the stock imagery and rewrite the title slide.

Audio

Voiceover and audio

Quality is broadly solved; licensing and voice cloning consent are the real decisions.

  1. 1. ElevenLabsFree tier · ~$5–22/mo

    Most natural delivery and widest language support

  2. 2. OpenAI TTSUsage-based

    Cheapest per character via API

  3. 3. Built-in system voicesFree

    Free and offline for drafts

Free route

Free tiers cover a few thousand characters a month — enough for short videos.

Watch out

Cloning someone's voice without written permission is a legal and platform-policy problem.

How these picks are chosen

Recommendations weigh output quality first, then price, then how easily the tool fits a workflow you already have. Nothing here is sponsored and there are no affiliate links — where a free tier genuinely covers the job, that's listed as the free route instead of a paid pick.

This market moves monthly. Prices are indicative list rates and the leader in each category can change between releases, so check the vendor before committing to an annual plan.
