Built for this. Reads long files and whole error traces without losing the thread, which makes it good at explaining unfamiliar code and debugging in a chat window.

Watch out: The chat window has no access to your project. For multi-file work you need the agent below or a dedicated editor.

Strong fit. Describe an app and it builds and runs it in the browser, with the code editable and deployable from there.

Watch out: Credits burn quickly on iteration, and a generated app is a prototype until someone reads it. Pro is sold in token tiers from 10M a month up, so its price is the entry rate rather than the bill.

Built for this. Connects thousands of apps and now runs agents across them. The integration count is the moat — an agent is only as useful as what it can touch.

Watch out: The breadth is also the complaint — it is a lot of product to configure before it helps. The free plan is real but holds 60MB, so it is storage that runs out rather than time or seats.

Brain, the AI layer, is a separate product in the navigation and does not appear on these plan cards
Two things separate these and both are on every card.
Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai startup tools?
There is no single answer, which is why this page lists 10 rather than one: ChatGPT, Claude, Lovable, Bolt.new, Gamma, Zapier, Notion, HubSpot, Trello, ClickUp. 6 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
10 of the 10: ChatGPT, Claude, Lovable, Bolt.new, Gamma, Zapier, Notion, HubSpot, Trello, ClickUp. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
