AI guitar tone apps compared: matchers, modellers and chatbots
AI guitar tone tools come in four kinds. Matchers such as Tonelify, ToneAdapt, TonesMatch and ToneMatcher take a song and your gear and return knob positions for the amp you own. Modeller AI such as Positive Grid's Spark AI and BIAS X builds the sound inside its own amp models. Capture libraries such as TONE3000 give you real amps as free models, and general chatbots answer anything but do not know your amp's panel.
Which one fits depends on where your sound comes from. If you play a real amp in a room, you need a matcher, because the other kinds only work inside their own software or hardware. We make Tonelify, one of the matchers, so weigh this page with that in mind: every claim about another tool comes from that tool's own site, checked on 30 September 2026.
The tools side by side
The table groups the tools by what they produce: settings for your own amp, a sound inside a product, or a model of a real amp. The descriptions are each maker's own, shortened.
| Tool | Kind | Runs on | What it does, per its maker |
|---|---|---|---|
| Tonelify | Matcher | Web | Returns gain, EQ, pickup and effects order for the amp and guitar you name, from the documented rig behind the recording. No audio is analysed. |
| ToneAdapt | Matcher | Web, iOS | Researches the rig behind a song from rig rundowns and interviews, then translates it onto the channels and controls your amp and guitar have. |
| TonesMatch | Matcher | Web | Lists 17,916 researched tones, calibrated to your guitar and amp. Browsing the gear used on a song is free. |
| ToneMatcher | Matcher | Web, iOS | Writes a tone recipe for your amp and pedals, validated against the controls that exist on the models you pick. |
| ToneMirror | Matcher | Web | Lists 11,000+ songs, with amp settings, pickup position, tuning and pedal chain adapted to your rig. |
| Get That Tone | Matcher | Web | Lists 2,580+ songs. Searching is free; generating settings for your gear is on its paid plan. |
| ToneAmp | Matcher | iPhone | Lists 1,300+ songs, including Turkish rock, identifies songs with ShazamKit, and adapts tones to your gear on its Pro tier. |
| Spark AI | Modeller AI | Spark app, for Spark amps | Generates a Spark preset from a typed description of the tone. |
| BIAS X | Modeller AI | Mac and Windows, standalone or plugin | Builds a tone in its own amps and effects from a text prompt or an uploaded clip of a guitar tone. |
| ToneCraft | Modeller AI, plugin | Mac and Windows plugin | Sets its six built-in effects from a description or an uploaded guitar stem. Needs a free account. |
| OnePedal | Modeller AI, pedal | Hardware pedal and app | Analyses a song you search for or upload and recreates it with the pedal's virtual amps, cabinets and effects. |
| TONE3000 | Capture library | Web and a free plugin | Hosts community Neural Amp Modeler captures and impulse responses of real amps, pedals and cabinets. Free. |
| ChatGPT, Gemini | General chatbot | Web and apps | General-purpose assistants, not built around a gear database. |
Matchers: settings for the amp you already own
A matcher does not make sound. It tells you where to put the knobs on the amp, guitar and pedals you have, which makes it the only kind of AI tone tool that helps if you play a valve combo, a solid-state practice amp, or a modelling amp from a brand without its own AI. Matchers differ in three places: how many songs they cover, where the rig information comes from, and whether the answer sticks to the controls your amp really has.
On song count, the bigger catalogues are well ahead. TonesMatch lists 17,916 tones and ToneMirror 11,000 songs, while Tonelify's free library has 57 songs, each with its sources linked, although Tonelify also matches songs outside the library.
On controls, ToneMatcher says its recipes only reference controls that exist on the exact models you pick, and ToneAdapt says it translates onto the real channels and controls of your amp. For the amps in its catalogue, Tonelify takes the front panel from the maker's manual and writes the answer for those controls only.
Modeller AI: a tone inside someone else's amp
Positive Grid's Spark AI builds a preset in the Spark app from a description you type, and BIAS X does the same inside its desktop software, where it can also work from an uploaded clip. ToneCraft's plugin and Groundhog Audio's OnePedal work in a similar way with their own effects and virtual amps.
The result can sound good, but it only exists inside that product. If your sound comes from a Marshall or a Fender in the room, a Spark preset does not move to it. If you already own a Spark or use BIAS X, though, its own AI is the obvious place to start, because it writes straight into the presets you will play.
Captures: free, real amps, no matching
TONE3000 hosts community captures made with Neural Amp Modeler, along with impulse responses, and its plugin is free. A capture is one real amp at one setting, so it gets as close to a song as the capture someone made of it, and no closer.
It suits a player who records into a computer and wants a particular amp without owning it. It does not tell you how to set the amp you have.
Can I just ask ChatGPT?
General chatbots will write amp settings for any song and any amp, for free, and they are fine for a first idea. What they lack is a reliable list of the controls on your particular amp, so an answer can include a knob you do not have.
A simple check: ask for settings on a Boss Katana-50 MkII. BOSS's own manual shows no Presence knob on the 50, only on the 100-watt models, so an answer with a Presence setting was not written for your amp. Checking any answer against the owner's manual takes a minute and catches most of these.
How to test any tone tool in five minutes
Ask for a song whose rig is well documented and check the answer against the sources. Master of Puppets is a good test: James Hetfield recorded it on a Jackson King V through a Mesa/Boogie Mark IIC+ used as a preamp into Marshalls. An answer that names an ESP guitar is describing gear from after the album.
Then ask for settings on your own amp and hold them against its manual. Every control named should exist on your panel, the channel or amp model should be one your amp has, and the answer should say which pickup to use. Last, look for where the rig information came from: a claim you can check is worth more than one you cannot.
Which kind to choose
A real amp, valve or solid-state, in a room: a matcher. A Spark amp, or BIAS X on a computer: its built-in AI first. Recording into a computer and happy with a plugin: TONE3000 captures or an AI plugin such as ToneCraft. Just curious about one song: a chatbot or a free song page, checked against your amp's manual.
Whichever matcher you pick, try a song you know well on your own amp before paying, and compare it with the record at the same loudness. Tonelify's song pages show a free starting point and the sources behind each rig, and matching for your own amp and guitar starts with a seven-day free trial.
Common questions
What is the best AI app for guitar tone?
It depends on where your sound comes from. For a real amp, a matcher that writes its answer for your amp's actual controls; for a Spark amp or BIAS X, their built-in AI; for recording, Neural Amp Modeler captures or an AI plugin. Test any of them on a well-documented song and against your own amp's manual before paying.
Is there an app that tells you the amp settings for a song?
Yes. Matchers such as Tonelify, ToneAdapt, TonesMatch, ToneMatcher, ToneMirror, Get That Tone and ToneAmp take a song and return amp settings, and most of them adapt the settings to the guitar and amp you own. They differ in song count, platform and where their rig information comes from.
Can ChatGPT give me amp settings for a song?
It can give a starting idea for free, but it does not have a reliable list of your amp's controls. Check the answer against your owner's manual: a Presence setting for a Boss Katana-50 MkII, for example, points to a knob that amp does not have.
Are there free AI guitar tone tools?
TONE3000's captures and plugin are free, ToneCraft's plugin needs only a free account, and general chatbots are free. Most song-to-amp matchers let you browse songs or try them free and charge for settings adapted to your gear.
Does AI tone matching analyse the audio of the song?
Some tools do. BIAS X, ToneCraft and OnePedal can work from an uploaded recording. Tonelify works from the documented rig behind the recording and the gear you enter, as text, and never analyses audio.

Settings for your own amp
This guide covers what is true of every rig. For a specific song on a specific amp, Tonelify reads the documented chain behind the recording and returns gain, bass, middle, treble and presence values for the controls your amp actually has. Free for 7 days, no charge until the trial ends.
