Build a Source-Checked Competitor Table: A Computer Use Template

A useful competitor table lets another person check where each claim came from. The task in this tutorial is to compare Canva, Adobe Firefly, Leonardo.Ai, Ideogram and Recraft for a marketer preparing product images and social posts. The output is a comparison CSV plus a separate field-level evidence CSV. It is not an image quality ranking, and these five tools are not assumed to be direct substitutes for every part of Ofox.

Define the decision before opening five tabs

Write down the intended workflow: create a product image, change part of it, prepare readable text, keep recurring brand assets consistent and export a usable file. This gives the research a purpose. A long list of loosely related features would not tell the marketer which limitations need a follow-up test.

The table should distinguish image generation, selective image editing, background removal, text/layout, brand reuse, file formats, resolution, free-use restrictions and the unit used for paid usage. For commercial-use conditions, record the official source and applicable plan. Do not turn a marketing phrase into a legal guarantee.

Download the research kit: five-product comparison, field-level evidence, empty CSV templates and a reusable prompt. The prompt is a template, not an executed browser transcript.

Prepare the workspace and browser

Use a local Codex task with permission to create files in its workspace. Select the connected browser explicitly, since a built-in browser and an external browser can have different profiles and sign-in states. This exercise needs only public pages; it should not require a product subscription or a generation request.

Place targets.csv, both empty CSV templates and prompt.txt in the workspace. The targets contain the five selected official starting pages. They are entry points, not evidence that every requested field appears there. The agent should follow relevant official feature and documentation links that are visible on the page, recording the final URL for each fact.

If the browser is not available, consult the Computer Use permissions guide. An explicit access denial must be resolved through user controls; changing the tool or browser is not a research workaround.

Ask for evidence before the polished table

The prompt in the companion kit requests a row for each observed field. Each row contains product, field, value, source URL, source heading, a short supporting excerpt or paraphrase, collection time, plan/platform conditions and review status.

Use a two-stage prompt: “Return the evidence rows for review first; create the comparison table only after those rows are checked.” This reduces the temptation to compress uncertainty out of the final answer. It also makes mixed plan names and contradictory pages easier to notice.

A claim such as “exports SVG” must say which output or plan it describes. A feature page about vectors cannot establish that every generated raster image can be exported as editable vectors. Likewise, reading about text rendering does not measure spelling accuracy in a generated image.

Handle missing and conflicting information

Use explicit statuses; needs_clarification marks ambiguous quantities or units. not_verified means there is insufficient current evidence for the requested field. access_denied means the page could not be accessed under current permissions. conflict means the sources disagree. verified_vendor_statement means the field agrees with its cited official page; it does not mean the product was independently tested.

For prices, preserve currency, unit, billing period, plan and collection date. If annual and monthly billing controls are ambiguous, leave the amount unresolved. Never convert missing price information into a zero or label a free tier unlimited. Do not calculate a cheapest option from differently defined credits.

Review and export

Reopen every cited source for the fields used in the final comparison. Check the heading and limitation as well as the value. Remove an inference that the source does not support; do not just attach the homepage URL to it.

Write UTF-8 CSV with fixed columns, using a CSV writer to escape commas, quotation marks and line breaks. Import the fields as text in your spreadsheet application. Check that each product occupies one row and that source URLs are intact and can be opened or copied into a browser; automatic hyperlinks depend on the application. Keep the evidence file beside it so uncertainty is not lost when the summary is shared.

A partial worked example: five targets, three researched

Checked against official sources on September 28, 2026, the companion files contain five comparison rows and 32 field/status rows. The facts below came from official pages retrieved with web research, not from operating each product UI. Canva and Adobe Firefly remain unverified because the browser refused access. We did not use another method to retrieve their blocked pages. No images were generated in any product.

Sources: Leonardo editor, Ideogram Canvas, Recraft design features.

One useful finding is a qualification conflict inside the Ideogram Canvas page: the image menu associates PNG with Plus and above, while its export instructions mention Basic and above. We preserved a conflict status instead of choosing the more attractive claim. Its plan overview also tells readers to use live pricing for current entitlements and quantities. A static FAQ allowance should not override that instruction.

Another important distinction concerns commercial use. Recraft’s current terms restrict Free Tier Assets to personal use. A marketing page’s general discussion of commercial rights cannot establish that a free-plan output is suitable for a client campaign. The evidence file keeps this condition with its source; this is not legal clearance for a particular asset.

Each comparison cell with source evidence retains its available plan conditions, review notes and source URL. Denied and unresolved fields keep their status rather than an invented source. This is intentional: a neat Yes/No table would hide the precise limits that matter to the marketer. The files reopen with five product rows and consistent columns; a spreadsheet UI rendering check and a five-site browser repeat have not been done.

Reuse the workflow without overstating it

The reusable part is the evidence structure and review method. A second product category needs its own field definitions. Product capabilities and prices change, so date the table and recheck material fields before using it for a purchase. A research table can shortlist products for testing; it cannot replace a test of your own images, brand assets and final export requirements.
