AI · A practical guide

The right AI for the job.
No hype.

We use AI on every Stacklumen engagement — for code review, content drafts, research, internal docs. We also avoid it for plenty of things, and we don't think any single tool wins everywhere. Here's what we actually reach for, and why.

01 · Use it responsibly

Five rules we don't break.

These are the floor — everything below assumes you're operating inside them. Not a legal disclaimer, just what's worked for us across hundreds of AI-assisted deliverables.

01

Verify before you ship.

Treat AI output as a confident-sounding first draft, never a finished answer. Names, numbers, citations, legal language — all hallucinate-prone. Read every word before it leaves your hands.

02

Never paste anything you wouldn't email.

Anything you put in a public AI chat may be used for training and is stored on someone else's servers. Client data, internal financials, customer info, anything under NDA — keep it out, or use an enterprise plan with a zero-retention agreement.

03

Disclose when it matters.

Marketing copy and brainstorm output — fine. Anything where authorship matters (proposals, expert articles, client deliverables) — say AI helped. It's usually a non-issue if you mention it; it's a real issue if you hide it and someone notices.

04

Keep the human on the hook.

A person should still own every decision the AI helped with. The model can draft a refund policy; a human owns the consequence of shipping it. "The AI told me to" is not a defense.

05

Bias is real and quiet.

Every model is trained on a slice of the internet. That slice carries its biases — about who counts as default, what English sounds professional, whose problems get treated as universal. Watch for it.

02 · What to use for what

Eight common tasks, ranked picks.

For each task we list the tool we reach for first, why, and the alternative we'd pick if our primary wasn't a fit. Brand allegiance isn't a strategy.

01

Long-form writing + reasoning

Briefs, internal docs, policy drafts, anything where you need a model that holds onto a lot of context and reasons through it cleanly.

Pick first
Claude (Sonnet or Opus)

Best-in-class on long-context comprehension and writing that doesn't sound like every other AI. Strong at following nuanced style instructions.

If that's not a fit
  • ChatGPT — Fast, casual drafts where tone doesn't matter much. Free tier covers a lot of everyday writing.
  • Gemini — When you need to pull in real-time Google search results mid-draft.
02

Writing or debugging code

Pair-programming, refactoring, generating boilerplate, debugging a tricky stack trace.

Pick first
Claude (Sonnet / Opus) or Claude Code

Claude's coding output consistently leads on benchmarks and real-world refactors. Claude Code (CLI) lets it run commands and edit files directly. Cursor + Claude is the editor-integrated version.

If that's not a fit
  • GitHub Copilot — IDE-native inline completions while you type. Less context-aware than a chat, but lower friction.
  • ChatGPT — Quick standalone code questions when you're already there for something else.
03

Customer support + drafted replies

First-draft responses to inbound messages, FAQ writing, policy explanations.

Pick first
Claude

Safer defaults around tone and edge cases. Less likely to confidently invent a refund policy you don't actually have.

If that's not a fit
  • ChatGPT — Lower-stakes, high-volume support where a confident-sounding draft is more important than a careful one.
04

Quick everyday questions

Definitions, summaries, "what does this acronym mean", brainstorming a list of ideas.

Pick first
ChatGPT (free tier)

Free, fast, ubiquitous. For low-stakes one-shot questions, the easiest tool wins.

If that's not a fit
  • Claude — When your "quick question" actually involves a long document you want it to read.
  • Perplexity — When the answer needs a citation from the live web.
05

Image generation

Logos, illustrations, marketing visuals, mockups. Stacklumen does not ship AI-generated images for clients — we hire illustrators or commission photography — but here's where the tools stand if you're generating your own.

Pick first
Midjourney

Highest aesthetic ceiling. The best-looking generations of any tool we've tested. Discord-native, learning curve on prompts.

If that's not a fit
  • DALL·E (via ChatGPT) — You're already in ChatGPT and want something passable in one prompt with no setup.
  • Stable Diffusion / Flux — You want local, private, free generation and you're comfortable with technical tooling.
06

Research with citations

Anything where the answer needs to point at a source — competitive research, market sizing, finding case studies.

Pick first
Perplexity

Search-native. Every claim cites the source so you can verify.

If that's not a fit
  • ChatGPT with browsing — Already in your ChatGPT subscription — works when you don't want to spin up another tab.
  • Claude with web search — When the research is also a long-form synthesis and you want one tool to do both.
07

Voice + real-time conversation

Hands-free brainstorming, language practice, having something explained while you cook.

Pick first
ChatGPT voice mode

Best conversational latency, best voices, supports interruption. The closest thing to a real conversation.

If that's not a fit
  • Gemini Live — When you want the model to see what your camera sees while you talk.
08

Private + local

Anything that involves sensitive client data, internal financials, or anything you wouldn't paste into a public web form.

Pick first
Ollama running Llama or Mistral

Free, open-source, runs on your laptop. Nothing leaves your machine.

If that's not a fit
  • Claude API with zero-retention enterprise plan — You want frontier quality AND data privacy guarantees — pay for the enterprise tier.
03 · Marketing + content workflows

Where AI actually moves the needle on growth.

Blog → social → video → email is the loop most SMEs need to run, and it's where AI delivers the most leverage per dollar. Here's what we use across each step — content production, YouTube specifically, SEO, email, and customer research.

01

Blog + long-form content

SEO-targeted articles, thought-leadership posts, case studies. The places where 1,500+ words have to read like a human wrote them.

Pick first
Claude (Sonnet or Opus)

Strongest at structure, transitions, and not collapsing into AI-voice at length. Pair it with a brief + outline you write, not a one-line prompt.

If that's not a fit
  • Jasper / Copy.ai — You want template-driven blog flows with built-in SEO scoring baked in instead of doing the SEO check separately.
  • Notion AI — The article lives in Notion and you want generation inline with your other docs.
02

Short-form social (LinkedIn, X, threads)

Posts, threads, hooks, repurposing long-form into bite-size formats. Tone matters more than depth here.

Pick first
Claude with a voice prompt

Feed it five of your best past posts as the voice anchor, then ask it to write in that voice. Avoids the LinkedIn-default tone every model defaults to.

If that's not a fit
  • Taplio — LinkedIn-native — built around hooks, post scheduling, and pulling viral templates.
  • Typefully — Twitter/X threads with a clean drafting UX and built-in scheduling.
03

YouTube — scripts

Video scripts, intro hooks, B-roll callouts, end-screen CTAs. The hard part is the first 15 seconds; the rest is structure.

Pick first
Claude with a hook framework

Best at maintaining a consistent narrator voice across a 6-10 minute script. Drop in your channel's top three intros as examples and it patterns them well.

If that's not a fit
  • ChatGPT — You want quick variation on a script you already have — generate 5 different intros, pick one.
04

YouTube — titles, descriptions, tags

Where YouTube SEO actually lives. Title is the click; description is the rank.

Pick first
VidIQ

Plugged into YouTube's actual search data. AI suggestions are grounded in real keyword volume, not guesses.

If that's not a fit
  • TubeBuddy — Same category — pick whichever subscription you already have.
  • Claude — You've done the keyword research and just need 10 title variations from a known seed.
05

YouTube — voiceover + narration

You wrote the script and don't want to be on camera. Or you want consistent narration across a long series.

Pick first
ElevenLabs

Best voice quality on the market. Clone your own voice with a few minutes of clean audio, or pick from a library of natural-sounding presets.

If that's not a fit
  • Murf — Lower-volume use or a friendlier UI. Less natural ceiling but easier learning curve.
  • Descript Overdub — You're already editing in Descript and want voiceover inside the same tool.
06

YouTube — editing + clip extraction

Cutting a long-form video into short clips, removing filler words, generating captions, syncing B-roll.

Pick first
Descript

Edits video by editing the transcript. Cut a word, the video cuts. The single highest-leverage tool for a small content team.

If that's not a fit
  • Opus Clip — Pure clip extraction — feed it a podcast or webinar, get viral-shaped shorts back.
  • Submagic / CapCut AI — Animated captions + viral-style subtitle overlays for shorts/reels/TikTok.
07

Thumbnails + ad creative

YouTube thumbnails, ad creative variations, social graphics. The work where one good visual outperforms ten okay ones.

Pick first
Midjourney + Photoshop / Figma

Midjourney for the base imagery, then composite text + brand layers in Photoshop or Figma. AI generates the hero asset; a human ships it.

If that's not a fit
  • Canva AI — Lower-stakes thumbnails where speed matters more than uniqueness — built-in text + templates.
  • AdCreative.ai — You're running paid ads and need 20 creative variants for testing, fast.
08

SEO — content briefs + optimization

Keyword research, competitor analysis, content briefs that hit the structure search engines reward.

Pick first
Surfer SEO

Reverse-engineers ranking pages into briefs you can hand to a writer (or Claude). Scoring is grounded in actual SERP data.

If that's not a fit
  • Clearscope — Higher-end alternative used by content teams at scale. Strong topic modeling.
  • NeuronWriter — Cheaper Surfer alternative for solo creators or small teams.
09

Email campaigns + newsletters

Newsletter drafts, drip sequences, cold outreach, transactional copy.

Pick first
Claude for drafts, Beehiiv / ConvertKit for delivery

Generative quality matters more than the sending platform. Draft in Claude, paste into your ESP. Don't pay extra for "AI inside an email tool" when standalone is better.

If that's not a fit
  • Lavender — Specifically for cold sales email — scores subject lines and bodies against open/reply rates.
10

Customer research + interviews

Synthesizing customer interviews, finding patterns across support tickets, summarizing survey free-text.

Pick first
Claude (with the raw transcripts)

Largest context window of any consumer-grade model. Paste 50 pages of interviews, ask for themes, get them.

If that's not a fit
  • Dovetail — You're doing this regularly and want a research repository with tagging and search.
04 · Implementation tools

The wider stack, by category.

The matrix above covers tasks where AI is the work. This is the other half — tools where AI sits inside an existing job (CRM, support, scheduling, dev tooling) and quietly multiplies it. Reach for these as you hit the problem they solve, not all at once.

Workflow + automation

The connective tissue. Wire AI into the rest of your stack so it triggers automatically, not manually.

  • Zapier The default. 6,000+ integrations, AI agents built in, dead simple no-code triggers.
  • Make.com More power, more complexity. Visual scenarios for branching logic Zapier can't do cleanly.
  • n8n Self-hosted open source. Run it on your own server, pay nothing in API fees.
  • Pipedream For when you want to write actual code in the workflow steps.

Meeting + voice intelligence

AI-generated meeting notes, action items, follow-up emails. Highest-ROI category for most small teams.

  • Granola The best one we've tested. Local-first, never auto-joins, writes notes you actually use.
  • Fathom Free tier is genuinely usable. Strong on summaries and CRM integrations.
  • Fireflies Better for larger teams that want sentiment + speaker analytics on top of notes.
  • Otter Long-running incumbent. Transcript quality is excellent; UI is dated.

CRM + sales

AI-augmented pipelines, lead scoring, draft replies, deal summaries.

  • Attio New-default CRM with AI baked in. Auto-enriches contacts, drafts replies, builds reports.
  • HubSpot Breeze HubSpot's AI suite. Already in HubSpot? Use it. Not in HubSpot? Don't move just for the AI.
  • Clay Programmatic lead enrichment + outbound. Stacks 100+ data sources behind one workflow.

Customer support

AI-first ticket triage, knowledge-base answers, draft replies for human review.

  • Intercom Fin Best-in-class support AI. Resolves a real percentage of tickets end-to-end without a human.
  • Zendesk AI Enterprise-tier support. Plays nice with existing Zendesk workflows.
  • Plain For dev-tool / B2B support. AI built in, beautifully designed, founder-friendly pricing.

Notes, docs, knowledge

AI-aware writing surfaces. Where drafts live before they ship anywhere.

  • Notion AI Notion + AI = "AI Q&A across your entire workspace." Strong for distributed teams.
  • Coda AI Doc + database hybrid with stronger structured-data AI workflows than Notion.
  • Mem AI-native notes. Auto-tags, auto-links, auto-surfaces related notes as you write.

Project management + scheduling

Where work gets tracked + when it happens. AI is mostly a feature here, not a category.

  • Linear Best engineering PM tool, AI features in Beta. Issues, projects, cycles — everything fast.
  • Motion AI-scheduled calendar. Tell it your tasks, it auto-blocks time and reshuffles when life happens.
  • Reclaim Cheaper Motion alternative. Strong calendar habits without the full task layer.

Developer tooling

IDE + CLI tools where AI lives next to the code.

  • Cursor AI-native VS Code fork. Tab-complete that understands your whole repo, agentic edits.
  • Claude Code CLI agent that runs commands + edits files directly. The tool building Stacklumen, mostly.
  • GitHub Copilot The original. Still solid for inline completions if you want IDE-only AI without the agentic surface.
  • v0 / Lovable Prompt-to-UI generators. Great for prototyping a page in 30 seconds, less great for production code.
05 · Why we lean Claude

Where it earns the default slot.

We try every major model when it ships. Claude is what we reach for first on the work that actually crosses our desks — that's not a sponsored take, it's where our drafts come from cleanest.

Reasoning

Holds onto long context without losing the thread. The 200k+ token window is real, not a marketing number — we feed it whole codebases and full deal documents and it threads them.

Voice

Output reads like a person wrote it. Less of the corporate-LinkedIn voice GPT can drift into. Easier to steer toward a brand voice when you ground it with examples.

Code

Top-of-leaderboard on the coding benchmarks that map to real refactor work — not just leetcode. Claude Code in particular runs commands and edits files directly via CLI.

Safety defaults

Defers when it should, asks clarifying questions, refuses confidently on real edge cases. Lower hallucination rate on names, numbers, and citations than the alternatives we've tested.

That doesn't make it the right tool everywhere — see the matrix above. Claude doesn't generate images. It's not the cheapest free tier. For pure conversational latency in voice mode, ChatGPT still wins. Use the tool that fits the job.

06 · Where we don't use AI

A short list, by design.

The point isn't to use AI for everything. Some work is faster and better when a human owns it from the start. Here's what we deliberately keep off the AI's plate at Stacklumen.

  • Naming. Brand names, product names, headline copy that has to land in one shot. Models default toward safe and forgettable. We brainstorm with one in the room, then humans pick.
  • Final brand voice. A trained-on-the-internet model produces internet voice. To sound like you, it needs a corpus of you. We use AI to draft fast, then rewrite in the actual voice.
  • Client image generation. Stacklumen ships hand-photography or commissioned illustration on client work, not AI imagery. The tools are good and getting better — they still have a tell, and they raise legal questions we don't want to inherit.
  • High-stakes legal, financial, or medical language. Anything that creates legal exposure if it's wrong. The right answer there is a human professional, not a confident-sounding sentence.
  • Replying as a person. If something has someone's name on it, that person wrote it. AI drafts in a doc are fine; AI sending email as you is not.
07 · Stacklumen is AI-first

We carry the subscriptions so you don't have to.

Stacklumen runs on the same stack we recommend above. Every engagement we ship — Webflow build, custom application, retainer — uses these tools internally. Clients get the output of the stack without paying to evaluate it first, license it second, and learn it third.

A

The subscriptions, already paid for.

Claude Max + API. ChatGPT Plus. Midjourney. Perplexity Pro. ElevenLabs. Descript. Surfer SEO. Cursor. Zapier on the team plan. Granola, Attio, Linear. Roughly $1,800/mo of tooling sitting behind every Stacklumen engagement — you get the output, we eat the seat fees.

B

The integrations, already wired.

Auth, billing, support triage, content pipelines, lead enrichment — we've already plumbed these workflows on our own platforms. When we drop them into a client engagement, we're moving working patterns, not figuring it out for the first time on your time.

C

The judgment, already calibrated.

Which tool wins for which job changes month over month. We test new releases the week they ship and update what we recommend. You don't have to track which model leads at refactors this quarter or which voice-clone tool just got better — we already did.

D

Built for SMEs scaling up.

Small + mid-sized businesses can't afford to run the AI evaluation lab a Fortune 500 runs. Stacklumen is that lab — outsourced, on retainer, embedded with your team. We bring frontier tooling to engagements that would otherwise have to pick whatever showed up in last month's newsletter.

That's the whole offer: we run the AI-first agency so you don't have to staff one. Same Slack channel, same weekly demos, full code ownership — now with a tool stack that's been benchmarked against the work you're trying to do.
